IMF-006-02-0009-en	What are semantic qualifiers, and what do they do to a case?	Contrasting descriptors such as acute against chronic or focal against diffuse; they compress many observations into a form that activates useful illness patterns.

IMF-006-02-0011-en	Distinguish overdiagnosis from a false positive.	Overdiagnosis correctly identifies a condition that would never have caused symptoms or harm in that person's lifetime; a false positive is simply an incorrect result.

IMF-007-01-0004-en	Why does the normal activation sequence reach the septum and apex before much of the free wall?	The His bundle, bundle branches and Purkinje fibres distribute activation rapidly in that order, which produces efficient ejection.

IMF-007-01-0023-en	Why must increased myocardial oxygen demand be met almost entirely by increased coronary flow?	The myocardium already extracts a high fraction of delivered oxygen at rest, so extraction cannot rise much further.

IMF-007-02-0002-en	What do the end-diastolic and end-systolic pressure-volume relationships each reflect?	The end-diastolic relationship reflects passive compliance; the end-systolic relationship reflects contractile state more closely, though loading and geometry still matter.

IMF-007-02-0005-en	Why does wall thickening follow pressure overload while chamber enlargement follows volume overload?	Thickening initially reduces wall stress for a given pressure, whereas volume overload increases chamber size and tends to add sarcomeres in series.

IMF-007-02-0006-en	Why can a patient have symptoms despite a preserved ejection fraction?	Ejection fraction describes only the proportion ejected from the volume present; a thick, poorly compliant ventricle fills at high pressure, which is transmitted to atrium and veins.

IMF-007-02-0009-en	Explain ventricular interdependence and one situation in which it causes collapse.	The ventricles share the septum inside the pericardium, so acute right-ventricular dilation shifts the septum leftward and reduces left filling, as in massive pulmonary vascular obstruction.

IMF-007-02-0012-en	Give one way each that sodium-channel block and potassium-channel block can be proarrhythmic.	Sodium-channel block can slow conduction enough to promote a different circuit in diseased myocardium; potassium-channel block prolongs repolarisation and permits early afterdepolarisations.

IMF-008-01-0001-en	Why is the absolute pressure at one point less informative than the gradient between two points?	Flow is driven by a pressure difference and opposed by resistance, so flow follows the gradient rather than any single absolute value.

IMF-008-01-0002-en	For laminar flow in a cylindrical tube, how does resistance depend on length, viscosity and radius?	It varies directly with length and viscosity and inversely with the fourth power of the radius, which is why small arteriolar diameter changes have large effects.

IMF-008-01-0004-en	Why does blood velocity fall in capillary beds even though each capillary is tiny?	Velocity equals flow divided by total cross-sectional area, and the combined capillary area is enormous, so transit is slow and exchange is supported.

IMF-008-01-0005-en	A patient has no audible murmur or bruit. Why does that not exclude vascular disease?	Murmurs and bruits arise from turbulence, which needs conditions such as high velocity, large diameter, low viscosity or abrupt narrowing, so disease can be present silently.

IMF-008-01-0006-en	How is mean arterial pressure approximated from a cuff reading, and why is it not the midpoint of the two values?	Diastolic pressure plus one third of the pulse pressure, because at normal rates mean pressure lies closer to diastolic than to systolic pressure.

IMF-008-02-0004-en	Why can a pressure that one patient tolerates cause cerebral or renal hypoperfusion in another if it is lowered abruptly?	Chronic hypertension shifts the autoregulatory operating range, so flow falls once pressure drops below that shifted range.

IMF-008-02-0005-en	Which two renal mechanisms stabilise filtration, and what does each respond to?	The myogenic response of the afferent arteriole to stretch, and tubuloglomerular feedback to sodium chloride delivery at the macula densa, which also modifies renin release.

IMF-008-02-0006-en	What does the endothelial glycocalyx contribute, and what disrupts it?	It influences permeability, mechanosensing, coagulation and leukocyte interaction and supports the effective oncotic gradient; inflammation, hyperglycaemia, ischaemia-reperfusion and mechanical stress disrupt it.

IMF-008-02-0007-en	How can visible oedema coexist with intravascular volume depletion?	Increased permeability lets protein-rich fluid leave the circulation, so tissue swelling grows while effective circulating volume falls.

IMF-008-02-0008-en	How do unstressed and stressed volume differ, and what does venoconstriction do to them?	Unstressed volume fills vessels without generating much pressure while stressed volume stretches the system and drives venous return; venoconstriction shifts volume into the stressed compartment, raising mean systemic filling pressure without added fluid.

IMF-008-02-0009-en	How do spontaneous inspiration and positive intrathoracic pressure differ in their effect on venous return?	Spontaneous inspiration lowers right-atrial pressure and usually supports return, whereas positive pressure raises it and reduces the return gradient, especially with hypovolaemia.

IMF-008-02-0010-en	Why does a normal or restored arterial pressure not guarantee normal tissue perfusion?	Microvascular flow can be heterogeneous through endothelial swelling, leukocyte adhesion, microthrombi, altered red-cell deformability, shunting and impaired vasomotor control, so extraction stays limited despite adequate global delivery.

IMF-008-02-0011-en	Why is a raised lactate not a direct meter of whole-body oxygen absence?	It can rise through reduced oxidative metabolism, adrenergic acceleration of glycolysis, impaired clearance or regional stress, so it serves as a severity and trajectory marker instead.

IMF-009-02-0010-en	Why can the pressure gradient across a severely stenotic valve be low?	The gradient rises with flow, so a small stroke volume produces a low gradient despite severe anatomical narrowing.

IMF-009-02-0011-en	Why is murmur loudness an unreliable guide to lesion severity?	Intensity follows flow and pressure difference, so very low output softens a severe stenotic murmur and pressure equalisation shortens a regurgitant sound despite dangerous physiology.

IMF-010-01-0001-en	What defines shock, and why can blood pressure be normal in a shocked patient?	Shock is acute circulatory failure causing inadequate tissue perfusion and cellular oxygen use; pressure may be low, normal, or temporarily maintained.

IMF-010-01-0002-en	State the determinants of oxygen delivery as the manuscript gives them.	Oxygen delivery equals cardiac output multiplied by arterial oxygen content, and cardiac output equals heart rate times stroke volume.

IMF-010-01-0003-en	Why can a patient have a normal oxygen saturation yet inadequate oxygen delivery?	Arterial oxygen content depends mainly on haemoglobin concentration as well as saturation, so anaemia or low cardiac output can leave delivery insufficient.

IMF-010-01-0004-en	What happens to oxygen consumption once delivery falls beyond the critical point?	Increased extraction no longer compensates, consumption becomes supply-dependent, anaerobic metabolism increases, and lactate may rise.

IMF-010-01-0005-en	Why is lactate a severity and trend marker rather than a direct meter of tissue hypoxia?	It also rises from adrenergic stimulation, reduced clearance, mitochondrial dysfunction, seizures, or drugs.

IMF-010-01-0006-en	Why can an organ be poorly perfused despite an apparently adequate arterial pressure?	Effective perfusion also depends on local resistance, venous pressure, autoregulation, microcirculation, and baseline disease, so a congested organ perfuses poorly.

IMF-010-01-0007-en	In hypovolaemic shock, what lowers stroke volume, and why may the expected signs be absent?	Reduced venous return lowers stroke volume; medicines, age, pregnancy, or neurogenic states can alter the tachycardia, vasoconstriction, and cool skin.

IMF-010-01-0008-en	What is characteristic of filling pressures in cardiogenic shock, and what follows from that?	Filling pressures are often high, producing pulmonary or systemic congestion, although right-sided and left-sided patterns differ.

IMF-010-01-0011-en	Name the causes of obstructive shock and the treatment principle that follows from them.	Massive pulmonary embolism, cardiac tamponade, tension pneumothorax, and dynamic hyperinflation; the obstruction must be relieved rather than escalating fluid or vasopressor doses.

IMF-010-01-0012-en	Trace the mechanism by which tamponade produces pulsus paradoxus during spontaneous inspiration.	Greater right-sided venous return displaces the shared septum leftward within the restricted pericardium, left-ventricular filling and stroke volume fall, and systolic pressure drops excessively on inspiration.

IMF-010-01-0013-en	In tamponade, what is the anatomical problem, and why can contraction still look vigorous?	Filling is restricted from outside the heart rather than contraction failing, so a vigorously contracting but underfilled ventricle still delivers little blood.

IMF-010-01-0015-en	Which other condition can produce pulsus paradoxus, and what does that imply for its interpretation?	Severe obstructive airway disease can produce it, so the sign must be connected with filling mechanics and the overall clinical state before a cause is assigned.

IMF-010-01-0016-en	Why does a single normal blood pressure reading not exclude shock?	Compensated shock can preserve pressure, and warm vasodilated shock may even show bounding pulses early, so perfusion must be examined directly.

IMF-010-01-0017-en	What does a fluid bolus test, and against which observations is the response judged?	It tests whether increasing stressed intravascular volume improves output; response is judged by pressure, pulse, perfusion, urine output, lung findings, and dynamic measures when available.

IMF-010-02-0006-en	What does fluid responsiveness mean, and what does it fail to prove?	It means stroke volume is likely to rise after preload increases; it does not prove that fluid is the best treatment or that tissue perfusion will improve.

IMF-011-01-0011-en	Why can a low circulating iron alone not show whether true deficiency or inflammatory restriction is operating?	The measurement describes only the circulating compartment, whereas haemoglobin production also depends on storage, release, transport, uptake, and the marrow's ability to use delivered iron.

IMF-013-01-0016-en	How does the ventilation-perfusion ratio differ between the lung apex and the dependent bases?	At the apex perfusion falls more than ventilation so the ratio is relatively high, while at the bases both are greater but perfusion predominates so the ratio is lower.

IMF-013-01-0022-en	By which two mechanisms does carbon monoxide impair oxygen transport?	It occupies haemoglobin binding sites and increases affinity at the remaining sites, so both carriage and unloading fall.

IMF-013-01-0023-en	In the red cell, what does carbonic anhydrase do, and what becomes of the bicarbonate formed?	It accelerates conversion of carbon dioxide and water to carbonic acid, which dissociates, and bicarbonate then exits in exchange for chloride while haemoglobin buffers hydrogen.

IMF-013-02-0001-en	Why can alveolar-arterial oxygen difference trends not be compared across different oxygen devices?	A high inspired fraction raises alveolar oxygen greatly, so the numerical gradient grows, and variable-performance devices deliver a fraction that depends on the patient's inspiratory flow and breathing pattern.

IMF-013-02-0004-en	Why does anaemia lower the carbon monoxide diffusing capacity, and what can raise it?	Less haemoglobin is available to bind the test gas, while polycythaemia and alveolar haemorrhage can raise the measurement.

IMF-013-02-0006-en	Which assumption of pulse oximetry do dyshaemoglobins violate, and what measurement answers this?	Pulse oximeters assume ordinary oxyhaemoglobin and deoxyhaemoglobin, so co-oximetry with multiple wavelengths is used to estimate carboxyhaemoglobin and methaemoglobin more directly.

IMF-013-02-0007-en	Which mechanisms raise carbon dioxide when oxygen is given in chronic hypercapnic disease?	Improved oxygenation releases carbon dioxide from haemoglobin, reversal of hypoxic pulmonary vasoconstriction increases flow to poorly ventilated units, and reduced ventilatory drive may contribute in some patients.

IMF-013-02-0010-en	A patient's oxygen requirement is rising. Why is simply increasing the flow an inadequate response?	A rising requirement is itself a signal of deterioration, so device fit, airway, secretions, alveolar collapse, pneumothorax, pulmonary oedema, embolism, and low cardiac output are reconsidered.

IMF-014-01-0018-en	In susceptible chronic hypercapnic disease, why is oxygen controlled and reassessed rather than withheld?	Oxygen must not be withheld from a dangerously hypoxaemic patient, but worsened ventilation-perfusion matching, the Haldane effect, and altered ventilatory drive can raise carbon dioxide.

IMF-018-02-0008-en	In hypokalaemic metabolic alkalosis, what does the presence or absence of hypertension suggest?	With hypertension it suggests mineralocorticoid or channel-driven sodium retention; without hypertension it suggests vomiting, diuretics, or inherited salt-wasting physiology.

IMF-019-01-0002-en	Which reaction does carbonic anhydrase accelerate, and where does the manuscript locate the enzyme?	The combination of carbon dioxide with water to form carbonic acid, which dissociates into hydrogen and bicarbonate; it acts in red cells, kidney, and other tissues.

IMF-019-01-0004-en	How does the proximal tubule reclaim filtered bicarbonate, and why does that not add new buffer?	By hydrogen secretion and carbonic-anhydrase reactions, which only recover existing buffer; new bicarbonate appears when hydrogen is excreted with urinary buffers instead of being returned to blood with bicarbonate loss.

IMF-019-01-0005-en	Which urinary buffer becomes titratable acid, and which buffer can be adapted in quantity?	Phosphate accepts secreted hydrogen as titratable acid; ammonium is the quantitatively adaptable buffer, and acidosis increases ammoniagenesis.

IMF-019-01-0006-en	Trace how the kidney makes ammonium and traps it in the urine.	Proximal cells metabolise glutamine to ammonium and bicarbonate; ammonia diffuses into the collecting system, binds secreted hydrogen, and becomes trapped as ammonium.

IMF-019-01-0008-en	Compensation limits pH change but never carries it past normal. What follows if measured compensation differs substantially from the expected value?	Another primary disorder is present.

IMF-019-01-0009-en	How is the anion gap calculated, which electrolyte is usually omitted, and what does it estimate?	Sodium minus chloride and bicarbonate, with potassium commonly omitted; it estimates unmeasured anions.

IMF-019-01-0010-en	Sodium is 138, chloride 98, and bicarbonate 10. Work out the anion gap and say what it points to.	Chloride and bicarbonate total 108, so the gap is 138 minus 108, that is 30; the gap is raised, so unmeasured anions such as lactate, ketones, retained renal acids, or toxic alcohol metabolites should be sought.

IMF-019-01-0011-en	Why can a low albumin conceal a high-gap acidosis?	Albumin is a major unmeasured anion, so a low albumin lowers the expected gap and a pathological rise can sit within an apparently normal value.

IMF-019-01-0012-en	What does a normal-gap metabolic acidosis usually reflect, and which causes are listed?	Bicarbonate loss or impaired renal acid excretion with chloride retention, from diarrhoea, pancreatic or intestinal loss, renal tubular acidosis, early kidney disease, or chloride-rich fluid administration.

IMF-019-01-0013-en	A patient with severe metabolic acidosis breathes deeply and rapidly. Why is that not evidence of primary lung disease?	Kussmaul breathing is the respiratory compensation, the lungs raising ventilation to lower carbon dioxide.

IMF-019-01-0014-en	When does lactic acidosis arise, and why is treating the lactate number inadequate?	It arises when production exceeds clearance, and the number does not identify the mechanism, which may be tissue hypoperfusion, severe hypoxaemia, seizures, adrenergic stimulation, liver dysfunction, mitochondrial toxins, drugs, malignancy, or thiamine deficiency.

IMF-019-01-0015-en	Metabolic alkalosis needs generation and maintenance. What is required for it to persist?	Impaired renal bicarbonate excretion, commonly from volume and chloride depletion, reduced filtration, potassium deficiency, or ongoing mineralocorticoid effect.

IMF-019-01-0016-en	What does urine chloride separate in metabolic alkalosis, and what confounds it?	Chloride-responsive states such as remote vomiting or diuretic effect from chloride-resistant states with ongoing mineralocorticoid activity; active diuretics and kidney disease complicate the interpretation.

IMF-019-01-0017-en	What harms follow when the blood pH becomes severely alkalotic?	Cerebral and coronary flow fall, ionised calcium is lowered, potassium shifts into cells, and arrhythmia is promoted.

IMF-019-01-0018-en	Why can a near-normal pH hide severe chronic hypercapnia?	Over days the kidneys retain bicarbonate and excrete acid, so chronic compensation returns pH toward normal while carbon dioxide stays high, and a further acute rise gives acute-on-chronic respiratory acidosis.

IMF-019-01-0019-en	In metabolic acidosis the carbon dioxide is low. When may that be called a separate respiratory alkalosis?	Only when it falls more than predicted; otherwise the low carbon dioxide is the expected compensation.

IMF-019-01-0020-en	Which two acid-base disorders does salicylate toxicity classically combine, and why can the pH mislead?	Respiratory alkalosis from central stimulation together with high-gap metabolic acidosis, so a near-normal pH can conceal severe poisoning.

IMF-019-01-0021-en	Why does a normal osmolar gap fail to exclude methanol or ethylene glycol poisoning?	The early osmolar gap can fall as the parent alcohol is metabolised to toxic organic acids and the anion gap rises, so neither gap excludes late poisoning.

IMF-019-01-0023-en	Acid-base state and potassium interact, but simple rules have exceptions. Which exceptions does the manuscript give?	Mineral acidosis tends to shift potassium out of cells while organic acids may behave differently, and insulin treatment of ketoacidosis shifts potassium into cells even when total body potassium is depleted.

IMF-019-01-0024-en	Bicarbonate therapy is not indicated in every acidosis. What harms can it cause?	It adds sodium, generates carbon dioxide, can lower ionised calcium, shift potassium, expand volume, and overshoot.

IMF-019-02-0002-en	Bicarbonate is 8 in metabolic acidosis and the measured carbon dioxide is 32. Work out the expected value and interpret the difference.	One and a half times 8 is 12, plus 8 gives an expected carbon dioxide of about 20, so a measured 32 is higher than expected and indicates concurrent ventilatory failure.

IMF-019-02-0004-en	Why is loss of respiratory compensation urgent in severe metabolic acidosis, and what makes intubation hazardous?	The patient must sustain a high minute ventilation, so sedation, fatigue, chest disease, or neuromuscular weakness causes a sudden pH fall, and intubation is hazardous if post-intubation ventilation fails to match the previous compensatory demand.

IMF-019-02-0005-en	Carbon dioxide has risen. How do you read a bicarbonate that is lower, or higher, than that rise would predict?	Acute retention raises bicarbonate only a little through buffering and chronic retention raises it more through renal acid excretion, so less bicarbonate than expected suggests a concurrent metabolic acidosis and more suggests metabolic alkalosis or a higher previous baseline.

IMF-019-02-0006-en	What is post-hypercapnic metabolic alkalosis, and what maintains it?	After chronic hypercapnia is corrected rapidly with ventilation the retained bicarbonate stays temporarily high, and volume depletion, chloride deficiency, potassium loss, and diuretics maintain it.

IMF-019-02-0008-en	How is the urine anion gap calculated, and what do a negative and a positive value suggest?	Sodium plus potassium minus chloride; a negative value suggests high ammonium chloride excretion and an appropriate renal response as in diarrhoea, and a positive value suggests reduced ammonium.

IMF-019-02-0009-en	Lactate is clearing but the pH stays low after chloride-rich resuscitation. What has happened, and why is it not treatment failure?	The organic-gap acidosis has been replaced by a hyperchloraemic acidosis as lactate or ketones clear, so the pH can remain low while perfusion is in fact improving.

IMF-019-02-0010-en	In the physicochemical approach, how do giving chloride and losing chloride move the strong-ion difference and the pH?	Giving chloride narrows the strong-ion difference and promotes acidosis, while losing chloride, or adding sodium without accompanying chloride, widens it and promotes alkalosis.

IMF-019-02-0011-en	Which weak acids does the physicochemical approach use besides carbon dioxide and the strong-ion difference, and what does a low albumin do?	Weak acids such as albumin and phosphate; a low albumin exerts an alkalinising effect that can offset another acidosis.

IMF-019-02-0012-en	Why can bicarbonate therapy worsen intracellular or central acidity even though blood bicarbonate rises?	It generates carbon dioxide, and if ventilation cannot eliminate the carbon dioxide produced, the acidity inside cells and centrally may worsen.

IMF-020-02-0013-en	Why can a kidney biopsy still miss the responsible lesion?	It samples a small piece of tissue, so patchily distributed disease can be missed and chronic scarring can be mixed with active lesions.

IMF-021-01-0001-en	Why is rapid renewal of the gut epithelium both protective and a source of vulnerability?	Rapid renewal helps repair injury, but it also makes the mucosa vulnerable to antimetabolites, radiation, inflammation, and ischaemia.

IMF-021-01-0002-en	What distinguishes the general effects of parasympathetic and sympathetic activity on the gut?	Parasympathetic activity generally promotes digestion, whereas sympathetic activity generally inhibits motility and secretion and constricts vessels.

IMF-021-01-0004-en	How does cholecystokinin coordinate the response to a meal rich in fat and protein?	Responding particularly to fat and protein, it stimulates pancreatic enzyme secretion, contracts the gallbladder, and slows gastric emptying.

IMF-021-01-0005-en	What distinguishes the lower oesophageal sphincter problem in achalasia from that in reflux?	In achalasia the sphincter fails to relax, impairing entry to the stomach; in reflux, inappropriate retrograde flow exposes squamous epithelium to acid.

IMF-021-01-0006-en	Why does gastric emptying slow when the duodenum contains acid, fat, or hypertonic chyme?	These signals, together with distension, indicate that processing capacity is exceeded, so the distal stomach meters chyme into the duodenum more slowly.

IMF-021-01-0007-en	How do segmentation, peristalsis, and the fasting migrating motor complex divide the work of small-intestinal motility?	Segmentation mixes chyme, peristalsis advances it, and after absorption the fasting migrating motor complex clears residue.

IMF-021-01-0008-en	How is parietal-cell acid secretion balanced between stimulation and restraint?	Histamine, acetylcholine, and gastrin stimulate parietal cells through converging pathways, while somatostatin and prostaglandins restrain secretion and support mucosal defence.

IMF-021-01-0009-en	Why are pancreatic proteases secreted as inactive precursors?	Because they are activated in the intestinal lumen rather than in the gland, which reduces the risk of pancreatic autodigestion.

IMF-021-01-0010-en	Why does pancreatic insufficiency particularly cause steatorrhoea and fat-soluble vitamin deficiency?	The pancreas supplies the digestive enzymes, including lipase with colipase for triglyceride, so its failure causes maldigestion that shows particularly as fat loss and fat-soluble vitamin deficiency.

IMF-021-01-0011-en	Why do bile acids matter for fat absorption, and what follows when the enterohepatic cycle is interrupted?	Their amphipathic structure emulsifies fat and forms micelles that carry lipids to the brush border; most are reclaimed in terminal ileum, so interruption can cause diarrhoea, fat malabsorption, or both.

IMF-021-01-0013-en	How does the absorptive route of long-chain fatty acids differ from that of shorter fatty acids?	Long-chain fatty acids and monoglycerides are re-esterified in enterocytes, packaged into chylomicrons, and delivered through lymph, whereas shorter fatty acids enter portal blood more directly.

IMF-021-01-0014-en	Why can disorders of either the gastric parietal cells or the terminal ileum impair vitamin B12 absorption?	Parietal cells secrete intrinsic factor, vitamin B12 must bind intrinsic factor, and the bound vitamin is absorbed in the terminal ileum.

IMF-021-01-0015-en	How does the response to fasting help distinguish osmotic from purely secretory diarrhoea?	Fasting tends to improve osmotic diarrhoea, which is driven by unabsorbed osmoles, but not purely secretory diarrhoea.

IMF-021-01-0016-en	Why does an association between a microbial pattern and a disease not prove that the microbes cause it?	Antibiotics, diet, infection, inflammation, and altered transit can themselves disrupt the microbial ecology, so association alone does not establish causation.

IMF-021-01-0017-en	Why are villus tips especially vulnerable to hypoxia?	Villi are efficient exchange structures, but their countercurrent circulation leaves the tips poorly protected against hypoxia.

IMF-021-01-0018-en	In intestinal ischaemia, why is pain disproportionate to early examination findings an important warning?	Peritonism and systemic collapse come later with infarction, so the early examination can appear deceptively mild despite severe ischaemia.

IMF-021-01-0019-en	Why are hepatocytes exposed to orally administered drugs before systemic distribution?	Absorbed substances reach the liver in portal blood, which traverses sinusoids where hepatocytes exchange across fenestrated endothelium before blood drains to central veins.

IMF-021-01-0020-en	Why are centrilobular hepatocytes more vulnerable to hypoxia and selected toxins than periportal cells?	Centrilobular cells have lower oxygen exposure and prominent drug-metabolising activity, whereas periportal cells receive more oxygen and support oxidative metabolism and urea formation.

IMF-021-01-0023-en	Why can refeeding after prolonged undernutrition be dangerous, and how is the risk managed?	It drives phosphate, potassium, and magnesium into cells, causing arrhythmia, weakness, respiratory failure, and neurological injury; identify risk, replace thiamine and electrolytes, start cautiously, and monitor closely.

IMF-021-02-0001-en	Why can stronger gut contraction without coordination worsen symptoms instead of improving transit?	Slow waves set windows for contraction, but propulsion requires spatial coordination, so stronger uncoordinated activity can worsen pain or obstruction.

IMF-021-02-0002-en	What distinguishes mechanical obstruction from ileus, and why does the distinction matter?	Obstruction creates a transition point with proximal distension, whereas ileus is diffuse failure of propulsion; both cause vomiting, sequestration, aspiration, and perforation, but definitive treatment differs.

IMF-021-02-0003-en	Why is blocking the gastric proton pump effective acid suppression, and why should long-term use be reviewed?	The pump is the final step of the histamine, acetylcholine, and gastrin pathways, so blocking it overcomes several upstream signals; long-term suppression can alter mineral or vitamin handling, infection risk, and drug absorption.

IMF-021-02-0005-en	Why does modest ileal dysfunction cause diarrhoea, whereas extensive ileal loss causes steatorrhoea?	Modest dysfunction sends excess bile acids into colon, stimulating secretion; extensive loss depletes the total bile-acid pool, so fat is malabsorbed.

IMF-021-02-0007-en	How does the stool osmotic gap help separate secretory from osmotic diarrhoea?	A low gap means measured electrolytes account for most stool osmolality, supporting secretion; a high gap suggests unmeasured osmoles.

IMF-021-02-0012-en	Why does post-pyloric feeding not remove aspiration risk?	Aspiration also depends on consciousness, reflux, positioning, oral hygiene, and airway protection, and post-pyloric feeding does not prevent aspiration of oral secretions.

IMF-021-02-0013-en	Why should a normal lactate not delay assessment when intestinal ischaemia is suspected?	It does not exclude early localised ischaemia; peritoneal signs, acidosis, and organ failure appear only as the process advances, so contrast imaging and surgical and vascular review are not delayed.

IMF-022-01-0005-en	How can recurrent hypoglycaemia make later episodes more dangerous?	Repeated episodes blunt autonomic warning, so counter-regulatory symptoms fail to alert the person and dangerous unawareness develops.

IMF-022-01-0006-en	Why is exogenous insulin essential for survival in type one diabetes, and what role do autoantibodies play?	Immune-mediated destruction of beta cells produces absolute insulin deficiency; autoantibodies support classification but are not the direct cause of tissue injury.

IMF-022-01-0009-en	Why can glycated haemoglobin misrepresent glucose exposure in some patients?	It estimates recent average exposure through red cells, so changes in red-cell lifespan, haemoglobin structure, pregnancy, kidney disease, transfusion or assay interference distort it.

IMF-022-01-0017-en	How does insulin deficiency in diabetic ketoacidosis produce a high-gap acidosis?	Without insulin restraint, lipolysis drives hepatic ketone production, and the ketoacids consume bicarbonate, producing high anion gap acidosis.

IMF-022-01-0018-en	Why is total-body potassium depleted in ketoacidosis even when initial serum potassium is normal or high?	Insulin deficiency, hypertonicity and acidaemia shift potassium out of cells, so the serum level masks losses of total-body stores.

IMF-022-02-0014-en	Why do protein intake and resistance exercise matter during weight reduction, especially in older or frail patients?	Loss of muscle during weight reduction reduces function and metabolic capacity, so adequate protein, resistance exercise and gradual monitoring protect it.

IMF-023-01-0001-en	Why can a hormone concentration not be read simply as a measure of gland activity?	It reflects secretion, distribution, binding, metabolism and clearance, not gland activity alone, so interpretation needs paired hormones, physiological context and dynamic response.

IMF-023-01-0002-en	How do peptide and steroid hormones differ in synthesis, storage and site of action?	Peptides are made as precursors, stored in vesicles, released by exocytosis and act on membrane receptors; steroids derive from cholesterol, are usually made on demand, cross membranes and regulate transcription via intracellular receptors.

IMF-023-01-0003-en	Why can pregnancy or liver disease distort a total hormone measurement without changing hormone action?	Only unbound hormone is readily available to tissues and clearance, so changes in binding proteins alter total concentration without changing free biological activity.

IMF-023-01-0004-en	How do trophic hormone levels distinguish primary gland failure from central failure?	Both give low peripheral hormone, but primary failure has high trophic drive, whereas central failure has an inappropriately low or normal trophic hormone.

IMF-023-01-0006-en	Why can a single hormone value be misleading?	Many hormones are pulsatile or circadian, for example growth hormone pulsing in sleep and cortisol peaking near waking, and meals, exercise, stress, posture, menstrual stage and acute illness also alter results.

IMF-023-01-0007-en	What distinct questions do suppression tests and stimulation tests answer?	Suppression tests ask whether autonomous secretion can be restrained; stimulation tests ask whether reserve can respond. Each should answer a defined question, not compensate for indiscriminate screening.

IMF-023-01-0008-en	How does hypothalamic control of prolactin differ from control of the other anterior pituitary hormones?	The other hormones are driven by releasing hormones, but dopamine tonically inhibits prolactin, although thyrotropin-releasing hormone can also stimulate it.

IMF-023-01-0009-en	In what ways can a pituitary mass cause disease, and what do upward and lateral extension damage?	It can secrete hormone, compress normal tissue, or both; upward extension compresses the optic chiasm, classically impairing temporal fields, and lateral invasion affects ocular motor nerves and sympathetic fibres.

IMF-023-01-0011-en	What stimuli release vasopressin, and how do they differ?	Osmoreceptors respond sensitively to rising effective osmolality, while substantial volume depletion provides a powerful non-osmotic stimulus.

IMF-023-01-0013-en	Why is diabetes insipidus most dangerous when water access is limited?	Deficient vasopressin secretion or renal resistance causes large volumes of dilute urine, so without free water intake hypernatraemic dehydration develops.

IMF-023-01-0014-en	How do treatment approaches differ between central and nephrogenic diabetes insipidus, and what can mimic both?	Central disease responds to desmopressin; nephrogenic disease needs correction of cause and less solute and urine load. Primary polydipsia can mimic the pattern, so plasma and urine concentration are compared under supervision.

IMF-023-01-0015-en	In inappropriate antidiuresis, why does treatment depend on symptom severity and duration?	Water retention lowers sodium while urine stays inappropriately concentrated, and overly rapid correction of chronic hyponatraemia can cause osmotic demyelination.

IMF-023-01-0016-en	Why is insulin-like growth factor one useful for screening growth hormone status, and what limits it?	It integrates growth hormone secretion over time, but nutrition, liver disease, kidney disease, pregnancy and age also influence it.

IMF-023-01-0017-en	What determines whether growth hormone excess causes gigantism or acromegaly, and how is excess confirmed?	Excess before epiphyseal closure causes gigantism and after closure acromegaly; diagnosis uses insulin-like growth factor one and failure of glucose to suppress growth hormone, then pituitary imaging.

IMF-023-01-0018-en	Why does diagnosing growth hormone deficiency usually require stimulation testing?	Symptoms are non-specific and a random growth hormone value is unhelpful, so other axes are assessed and reserve is tested by stimulation.

IMF-023-01-0019-en	How do suckling and delivery enable lactation?	Suckling reduces hypothalamic dopamine and so increases prolactin secretion, while falling sex steroids after delivery permit lactation in a breast prepared by pregnancy.

IMF-023-01-0020-en	How does hyperprolactinaemia cause infertility and bone loss, and why is galactorrhoea an unreliable sign?	High prolactin suppresses gonadotropin-releasing hormone, causing menstrual disturbance, infertility, sexual dysfunction and reduced bone protection; galactorrhoea is neither required nor specific.

IMF-023-01-0021-en	Why must a prolactinoma be distinguished from medication effect or stalk compression before treatment?	The same prolactin elevation has different implications: dopamine agonists suppress secretion and usually shrink prolactinomas, whereas drug effect or stalk interruption has a different cause to address.

IMF-023-01-0022-en	Why is adrenocorticotropic deficiency immediately dangerous, and which replacement must come first?	Cortisol support is lost, though aldosterone is usually kept by the renin-angiotensin system; cortisol is replaced before thyroid hormone, since thyroid replacement first can precipitate crisis.

IMF-023-01-0023-en	What distinguishes the presentation of thyroid-stimulating and gonadotroph pituitary tumours?	Thyroid-stimulating tumours cause central hyperthyroidism with non-suppressed thyroid-stimulating hormone, whereas gonadotroph tumours are often clinically non-functioning and present through mass effect.

IMF-023-02-0001-en	How can a hormone value be abnormal without gland hypersecretion, or normal despite disease?	Concentration integrates secretion, pulsatility, binding, distribution, conversion, degradation and clearance, and effect depends on receptor abundance and sensitivity, so normal levels can coexist with resistance.

IMF-023-02-0002-en	Why is endocrine physiology tissue-specific as well as systemic?	Local enzymes alter hormone action within tissues: deiodinases activate or inactivate thyroid hormone, 11-beta hydroxysteroid dehydrogenase controls cortisol access to mineralocorticoid receptors, and aromatase makes oestrogens from androgens.

IMF-023-02-0003-en	When is a trophic hormone within the reference range still abnormal, and when does a non-suppressed one need confirmation?	It is pathological when the target is clearly deficient. With a high target, a non-suppressed trophic value raises assay interference, resistance or autonomous central secretion, confirmed before imaging.

IMF-024-01-0003-en	How do paired thyroid-stimulating hormone and free thyroxine results distinguish primary from central hypothyroidism?	Primary disease gives high thyroid-stimulating hormone with low free thyroxine, whereas in central disease from pituitary or hypothalamic failure thyroid-stimulating hormone is inappropriately low or normal.

IMF-024-01-0004-en	Why should iron, calcium, food and gastrointestinal disease be considered when setting a levothyroxine dose?	They reduce levothyroxine absorption, and absorption is one of the factors, with body composition, age, cardiac disease, pregnancy and residual function, that determine the replacement dose.

IMF-024-01-0006-en	How do Graves disease, toxic nodules, thyroiditis and exogenous hormone each produce thyrotoxicosis?	Graves disease stimulates the thyroid-stimulating hormone receptor, toxic nodules secrete autonomously, thyroiditis releases stored hormone, and exogenous hormone bypasses synthesis.

IMF-024-01-0007-en	How does radionuclide uptake help identify the cause of thyrotoxicosis, and why cannot ultrasound replace it?	Increased uptake indicates active synthesis, whereas low uptake suggests destructive thyroiditis or exogenous hormone; ultrasound answers structural questions but does not replace biochemical classification.

IMF-024-01-0009-en	Which features raise concern about a thyroid nodule, and how is it evaluated?	Compression, suspicious nodes, radiation history, rapid growth, voice change or high-risk imaging raise concern; evaluation uses thyroid-stimulating hormone, ultrasound risk assessment and selective needle sampling.

IMF-024-01-0012-en	What stimulates renin release, and what suppresses the renin-angiotensin system?	Renin is released in response to reduced renal perfusion, reduced sodium chloride at the macula densa, and sympathetic stimulation; volume expansion suppresses the system.

IMF-024-01-0013-en	What hormone pattern distinguishes primary from central adrenal failure?	Primary failure destroys the cortex, giving cortisol and aldosterone deficiency with high adrenocorticotropic hormone and renin; central failure reduces adrenocorticotropic drive and usually preserves aldosterone.

IMF-024-01-0014-en	Why does hyponatraemia not distinguish primary from central adrenal insufficiency, and which features point to primary disease?	Hyponatraemia occurs in both forms through impaired water excretion, whereas hyperpigmentation, salt craving, hyperkalaemia and marked volume depletion suggest primary disease.

IMF-024-01-0016-en	How is endogenous Cushing syndrome divided by mechanism?	It is adrenocorticotropic-dependent when pituitary or ectopic secretion drives it, or independent when an adrenal lesion produces cortisol; overall, iatrogenic exposure is the most common cause of the syndrome.

IMF-024-01-0020-en	Why can total calcium misrepresent calcium status, and what is preferred when uncertainty is critical?	Albumin binds a substantial fraction of calcium, so total calcium changes with albumin and pH; direct ionised calcium measurement is preferable.

IMF-024-01-0023-en	Why is intravenous calcium for severe symptomatic hypocalcaemia given with cardiac monitoring?	Hypocalcaemia causes QT prolongation as well as tetany, seizures and laryngospasm, so severe symptoms need intravenous calcium under cardiac monitoring.

IMF-024-02-0001-en	Why does a large acute iodine load have different effects in normal, autonomous and autoimmune thyroid tissue?	In normal physiology it temporarily suppresses organification and release, but autonomous tissue uses the substrate to produce excess hormone, and susceptible autoimmune glands may become hypothyroid.

IMF-024-02-0002-en	Why should thyroid-stimulating hormone not be rechecked too soon after a levothyroxine dose change?	Hormone and feedback turnover are slow, so it takes weeks to reach a new steady state; testing early provokes repeated dose changes and oscillation.

IMF-024-02-0003-en	Why do thionamides help Graves-type synthesis-driven disease but not destructive thyroiditis?	Thionamides block synthesis, which drives hyperthyroidism, whereas destructive thyroiditis causes thyrotoxicosis by releasing stored hormone that thionamides cannot stop.

IMF-024-02-0004-en	Why is thyroid storm defined clinically rather than by hormone level, and in what order is it treated?	It is severe decompensation, not a hormone threshold; treatment blocks adrenergic effects, then new synthesis, then hormone release after synthesis blockade, then peripheral conversion and the trigger.

IMF-024-02-0005-en	How do inherited adrenal enzyme defects cause adrenal hyperplasia and varied clinical signs?	Cortisol deficiency raises adrenocorticotropic hormone, causing hyperplasia, while precursors are redirected so mineralocorticoid and androgen output rise or fall by block, giving salt loss, hypertension, virilisation or undervirilisation.

IMF-024-02-0006-en	Why does central adrenal failure usually preserve aldosterone?	Central failure removes adrenocorticotropic drive to cortisol, but aldosterone remains under renin-angiotensin regulation; hence hyperkalaemia, salt craving and high renin are more typical of primary disease.

IMF-024-02-0010-en	Before surgery for a catecholamine-secreting tumour, why is alpha blockade established before beta blockade and volume restored?	Alpha blockade first avoids unopposed vasoconstriction, and chronic vasoconstriction has reduced circulating volume, which often needs restoring before surgery.

IMF-024-02-0011-en	How does kidney failure lead to secondary hyperparathyroidism?	Failing kidneys retain phosphate and activate less vitamin D, and fibroblast growth factor 23 rises early but also lowers active vitamin D, so the parathyroid is stimulated and may become partly autonomous.

IMF-024-02-0012-en	Why can calcium replacement fail in severe magnesium deficiency, even though mild deficiency stimulates parathyroid secretion?	Magnesium is needed for parathyroid hormone release and action; severe deficiency paradoxically suppresses secretion and causes resistance, so calcium may not work until magnesium is corrected.

IMF-024-02-0013-en	How does the parathyroid hormone level split the differential diagnosis of hypercalcaemia?	Elevated or inappropriately normal levels point to primary hyperparathyroidism, tertiary disease, lithium or familial calcium-sensing variants; suppression favours malignancy, vitamin D pathways, granulomas, medicines or immobilisation.

IMF-025-01-0002-en	How does testicular development direct internal and external differentiation, and what happens when its products are absent?	The developing testis produces anti-Mullerian hormone and androgens that direct differentiation; in their absence, ovarian and female tract development proceeds through alternative pathways.

IMF-025-01-0003-en	What hypothalamic change initiates puberty, and how does it produce secondary sexual characteristics?	Pulsatile gonadotropin-releasing hormone activity, restrained in childhood, increases and drives luteinising and follicle-stimulating hormones; the resulting gonadal steroids produce secondary sexual characteristics, growth and bone maturation.

IMF-025-01-0004-en	How do theca and granulosa cells cooperate to produce oestradiol in the ovarian follicle?	Theca cells supply androgens, and granulosa cells, in follicles recruited by follicle-stimulating hormone, convert those theca-derived androgens to oestradiol.

IMF-025-01-0005-en	How can rising oestradiol both restrain gonadotropins and trigger ovulation?	Early in the rise it exerts negative feedback, but sustained high levels switch to positive feedback, generating the luteinising-hormone surge that triggers ovulation and luteinisation.

IMF-025-01-0006-en	Without pregnancy, what sequence leads from the corpus luteum to menstrual shedding?	The corpus luteum regresses, progesterone and oestradiol fall, spiral arteries constrict, and the functional endometrium sheds.

IMF-025-01-0007-en	In the testis, how are the roles of luteinising hormone and follicle-stimulating hormone divided?	Luteinising hormone stimulates Leydig-cell testosterone production, while follicle-stimulating hormone together with intratesticular testosterone supports Sertoli cells and spermatogenesis; inhibin contributes feedback.

IMF-025-01-0008-en	What distinguishes the neural control of erection from that of ejaculation?	Erection depends mainly on parasympathetic nitric-oxide signalling with smooth-muscle relaxation, arterial inflow and venous occlusion, whereas ejaculation uses sympathetic and somatic pathways.

IMF-025-01-0009-en	Why should sexual dysfunction be assessed by separate domains rather than one label?	It may arise from vascular, neurological, endocrine, medication, pain, psychological, relational or structural factors, so desire, arousal, orgasm, ejaculation, pain, fertility and satisfaction are assessed separately.

IMF-025-01-0011-en	Why is the placenta described as an active organ rather than a passive filter?	Its exchange depends on flow, surface area, membrane properties, metabolism and gradients, and it produces chorionic gonadotropin, progesterone, oestrogens, placental lactogen and other signals.

IMF-025-01-0012-en	How does the character of bleeding help distinguish placental separation before birth from placenta praevia?	Placental separation before birth causes painful bleeding with fetal compromise, whereas implantation over the cervical opening (praevia) typically causes painless bleeding.

IMF-025-01-0017-en	Why does insulin resistance rise later in pregnancy, and how does gestational diabetes arise from it?	It preserves nutrients for the fetus; pancreatic secretion normally compensates, and gestational diabetes results when that compensation fails.

IMF-025-01-0018-en	What keeps the fetal shunts (ductus venosus, foramen ovale, ductus arteriosus) open before birth?	High pulmonary vascular resistance and low placental resistance maintain the shunts that route blood around the liver and lungs.

IMF-025-01-0019-en	At birth, what closes the foramen ovale and what promotes ductal closure?	Lung expansion lowers pulmonary resistance and cord clamping raises systemic resistance, so rising left atrial pressure closes the foramen ovale functionally; oxygen and reduced prostaglandins promote ductal closure.

IMF-025-01-0021-en	How is bleeding normally limited after placental separation, and why is uterine atony therefore a major cause of postpartum haemorrhage?	Uterine contraction compresses the vessels and limits bleeding; an atonic uterus fails to contract, so the vessels are not compressed and bleeding continues.

IMF-027-01-0017-en	How does the cochlea separate frequencies, and how do inner and outer hair cells divide the work?	Basilar-membrane mechanics place high frequencies near the base and low near the apex; inner hair cells provide most afferent output, while outer hair cells amplify and sharpen tuning.

IMF-027-01-0018-en	Why does a unilateral central auditory lesion rarely cause complete deafness in one ear?	Auditory pathways relay bilaterally through brainstem, thalamus, and cortex, so input from each ear reaches both sides.

IMF-027-01-0020-en	Why is visceral pain diffuse and often referred to a skin site that is not injured?	Visceral input is sparsely represented and converges with somatic pathways, so pain is poorly localised and follows shared spinal segments rather than the actual injury site.

IMF-027-01-0022-en	Why do placebo and nocebo effects not imply that a patient's pain is fabricated?	They recruit genuine descending modulation, in which pathways from cortex, hypothalamus, periaqueductal grey, and medulla inhibit or facilitate dorsal-horn transmission.

IMF-027-01-0023-en	How does central sensitisation differ from peripheral sensitisation?	Peripheral sensitisation lowers nociceptor thresholds; central sensitisation amplifies spinal and supraspinal responses, enlarges receptive fields, and makes normally innocuous input painful.

IMF-027-01-0024-en	What distinguishes nociplastic pain from neuropathic pain?	Neuropathic pain results from disease or lesion of the somatosensory system; nociplastic pain reflects altered nociceptive processing without tissue or nerve damage sufficient to explain its severity.

IMF-027-02-0001-en	Why does perception combine current evidence with prior expectation, and when does this backfire?	Sensory noise, ambiguous input, and incomplete sampling make evidence uncertain; when priors become excessively strong, the process yields illusions, bias, or persistent threat interpretation.

IMF-027-02-0002-en	Why does convergence of visceral and somatic input onto spinal neurons help explain referred pain?	Convergence increases sensitivity but reduces localisation, so visceral signals arriving on neurons that also receive somatic input can be attributed to a somatic site.

IMF-027-02-0010-en	What distinguishes nociception from pain, and how can they diverge?	Nociception encodes potential tissue threat; pain is the conscious protective experience. Anaesthesia can block pain despite injury, and central sensitisation or neuropathy can sustain pain after danger has reduced.

IMF-027-02-0012-en	Why should long-term opioid benefit be demonstrated rather than assumed from short-term relief?	Opioids also produce tolerance, dependence, hyperalgesia, endocrine effects, constipation, sedation, and respiratory depression, so benefit must be shown through function and harm review.

IMF-029-01-0014-en	Why are brain and mind not competing explanations when psychiatric symptoms appear?	The same symptoms can arise from primary mental illness or from neurological disease, endocrine or metabolic disturbance, drugs, infection, or delirium, so both must be considered.

IMF-029-01-0015-en	How do the two regulators of sleep interact with light, and why is melatonin not an off switch?	Circadian timing, aligned to light by retinal input to the suprachiasmatic nucleus, combines with homeostatic pressure from wakefulness; melatonin signals biological night rather than switching consciousness off.

IMF-029-01-0016-en	How does rapid-eye-movement sleep differ from slow-wave sleep, and how are the two distributed across the night?	REM sleep brings cortical activation, vivid dreams, and skeletal-muscle atonia sparing the diaphragm, unlike NREM with reduced sympathetic activity; slow-wave sleep dominates early, REM later.

IMF-029-01-0017-en	Why do sleep-deprived people tend to underestimate their own impairment?	Subjective adaptation often exceeds objective recovery, so they feel better adjusted while vigilance, reaction time, and judgement remain impaired.

IMF-029-01-0018-en	Why can insomnia outlast its trigger, and why is cognitive behavioural therapy preferred over routine sedatives?	Perpetuating behaviours and conditioned arousal persist, which the therapy targets; sedatives help only selected short-term situations and risk dependence, falls, cognitive effects, and respiratory worsening.

IMF-029-01-0019-en	What sequence of events occurs in obstructive sleep apnoea, and why does a lack of sleepiness not exclude it?	Recurrent upper-airway collapse causes intermittent hypoxaemia, pressure swings, and arousal; daytime sleepiness is a common but not required feature, so its absence does not exclude disease.

IMF-029-01-0020-en	Why does a small unilateral hemispheric lesion not by itself cause coma?	Arousal depends on distributed ascending systems and awareness on bilateral cortical and thalamocortical function, so coma requires bilateral hemispheric dysfunction or injury to the arousal network.

IMF-029-01-0021-en	How do delirium and dementia differ, and why is hypoactive delirium a particular risk?	Delirium is an acute fluctuating failure of attention caused by physiological disturbance, dementia a chronic acquired decline; they can coexist, and hypoactive delirium is easily missed.

IMF-029-01-0022-en	What distinguishes a minimally conscious state, unresponsive wakefulness, and locked-in syndrome?	A minimally conscious state shows reproducible but limited awareness, unresponsive wakefulness has eye opening without behavioural evidence of awareness, and locked-in syndrome preserves consciousness but removes most motor output.

IMF-029-01-0023-en	How is cerebral perfusion preserved on standing, and what can cause orthostatic hypotension when this fails?	Baroreceptors drive vasoconstriction and a faster heart rate, aided by muscle pumping and hormones; failure may reflect volume depletion, drugs, autonomic neuropathy, neurodegeneration, or deconditioning.

IMF-029-02-0001-en	Why is apparently poor memory approached by identifying the failed operation rather than a damaged centre?	The same poor performance can arise because information was not attended to, not consolidated, not retrieved by effective strategies, or could not be expressed, each implicating a different network.

IMF-029-02-0002-en	Why should bedside testing begin with arousal and sustained attention before memory or language scores are interpreted?	Arousal and attention networks underpin every other test, so tasks such as digit span or months backward must show they are intact before other scores can be read as specific deficits.

IMF-029-02-0003-en	Why can behaviour in a quiet examination underestimate the daily-life disability of a frontal syndrome?	Frontal syndromes are shaped by fatigue, medication, mood, and the structure supplied by the environment, so a quiet examination setting can mask how disabled the patient is in daily life.

IMF-029-02-0004-en	How does the memory impairment of frontal disease differ from that of bilateral medial temporal injury?	Medial temporal injury causes severe anterograde amnesia with immediate span and motor skills relatively spared; frontal disease impairs organisation, free recall, and source monitoring, often improving with cueing or recognition.

IMF-029-02-0005-en	Why is establishing a reliable yes-or-no channel important when assessing language?	A patient who cannot understand language may seem confused, while a severely dysarthric patient may be cognitively intact, so a reliable channel prevents dangerous misclassification.

IMF-029-02-0007-en	How does loss of orexin signalling explain the features of narcolepsy type one?	Orexin stabilises wakefulness and prevents inappropriate state transitions, so its loss allows sleep attacks, cataplexy, sleep paralysis, and REM phenomena to intrude into wakefulness.

IMF-029-02-0010-en	How do time awake in bed, irregular rising, and excessive time in bed each maintain insomnia?	Time awake in bed conditions the bed as a cue for vigilance, irregular rising weakens circadian stability, and excessive time in bed reduces sleep pressure.

IMF-029-02-0011-en	What does a unilateral dilated, poorly reactive pupil with declining consciousness suggest, and what can mimic it?	It suggests compression of the third nerve and requires emergency action, although ocular disease and drugs can produce a similar pupil.

IMF-029-02-0012-en	Why is an isolated Glasgow Coma Scale total less informative than component scores and trend?	Intubation, aphasia, deafness, paralysis, sedation, and facial trauma distort individual components, so the total can mislead while components and change over time show the true pattern.

IMF-029-02-0013-en	Why is hypoactive delirium dangerous, and what role do antipsychotics have?	Its quiet withdrawal is mistaken for cooperation or fatigue; antipsychotics do not cure delirium and are reserved for selected severe distress or immediate safety risk after reversible triggers are addressed.

IMF-029-02-0014-en	How does the heart-rate response on standing distinguish volume depletion from neurogenic orthostatic hypotension?	In volume depletion heart rate usually rises as pressure falls, whereas in neurogenic orthostatic hypotension the rise is disproportionately small because sympathetic efferent failure is part of the disease.

IMF-030-01-0015-en	When does a convulsive seizure become status epilepticus, and how is persistent coma afterwards approached?	At about five minutes or recurrence without recovery: give a benzodiazepine promptly, then a longer-acting antiseizure medicine; persistent coma may be non-convulsive status and needs electroencephalography.

IMF-030-01-0016-en	Why does intracranial pressure rise steeply once compensation is used up?	The rigid skull initially compensates by shifting venous blood and cerebrospinal fluid, but once that reserve is exhausted, small volume increments sharply raise pressure.

IMF-030-01-0017-en	What does the combination of hypertension, bradycardia, and irregular respiration signify in raised intracranial pressure?	It is a late sign of dangerous brainstem distortion; papilloedema can be absent in acute deterioration, so its absence does not reassure.

IMF-030-01-0018-en	What is the role of brief controlled hyperventilation in raised intracranial pressure?	It is a rescue bridge in imminent herniation, not routine therapy; definitive treatment may require lesion evacuation, cerebrospinal-fluid drainage, or decompression.

IMF-030-01-0019-en	How should cultures, antimicrobials, and investigations be sequenced in suspected meningitis?	Obtain cultures and begin empirical antimicrobials promptly without harmful delay for imaging or lumbar puncture; cerebrospinal-fluid pattern, molecular tests, immune status, and exposure then refine diagnosis.

IMF-030-01-0020-en	What lesion pattern defines multiple sclerosis, and how do relapse treatment and disease-modifying therapy differ in purpose?	Inflammatory demyelinating lesions disseminated in time and central nervous system space; corticosteroids may treat acute relapses, while disease-modifying therapy reduces future inflammatory activity.

IMF-030-01-0021-en	Why can small-fibre neuropathy be missed by routine testing, and how does large-fibre injury differ?	Small-fibre injury causes burning pain and autonomic symptoms with relatively preserved strength and routine nerve-conduction studies, whereas large-fibre injury impairs vibration, proprioception, reflexes, and balance.

IMF-030-01-0022-en	What must be monitored in Guillain-Barre syndrome, and which treatments modify the disease?	Vital capacity, swallowing, rhythm, and pressure, because deterioration can be abrupt; intravenous immunoglobulin or plasma exchange modifies disease, whereas corticosteroids alone do not.

IMF-030-01-0023-en	What clinical combination distinguishes Lewy body disease from Alzheimer disease?	Alzheimer disease begins with progressive episodic-memory impairment, whereas Lewy body disease combines cognitive fluctuation, visual hallucinations, parkinsonism, sleep behaviour disorder, and autonomic dysfunction.

IMF-030-01-0024-en	Because diagnosis of neurodegeneration remains clinical, which reversible contributors must be considered?	Drugs, depression, sleep apnoea, sensory loss, thyroid disturbance, vitamin deficiency, hydrocephalus, infection, and subdural blood, since these can be corrected.

IMF-030-02-0001-en	What three questions frame neurological diagnosis, and what does a sudden maximal deficit suggest?	Where the lesion is, what process can act there, and how quickly it developed; a sudden maximal deficit points toward vascular interruption, haemorrhage, seizure, or trauma.

IMF-030-02-0002-en	Why should a low stroke screening score not reassure when posterior-circulation signs are present?	Posterior-circulation stroke may cause diplopia, dysphagia, dysarthria, severe gait or truncal ataxia, crossed findings, or reduced consciousness, and a low score does not make these benign.

IMF-030-02-0003-en	Why is penumbral tissue potentially salvageable, and what can convert it into core?	In the penumbra electrical function fails before membrane integrity, but systemic hypotension, hypoxaemia, fever, and marked glucose disturbance can recruit it into the core.

IMF-030-02-0004-en	How do intravenous thrombolysis and mechanical thrombectomy relate in acute ischaemic stroke?	They are complementary rather than competing: thrombolysis treats eligible patients after haemorrhage and important contraindications are excluded, and thrombectomy physically removes selected large-artery thrombi.

IMF-030-02-0005-en	Why is swallowing screened before oral intake after stroke?	Because silent aspiration is common; stroke care remains physiological after reperfusion decisions, and complications such as fever, dehydration, and malnutrition worsen recovery.

IMF-030-02-0006-en	Why does spontaneous improvement of an acute deficit not close the episode?	The event may be a transient ischaemic attack or a stroke that has recanalised, and early recurrence risk still requires assessment.

IMF-030-02-0007-en	How does the location of an intracerebral haemorrhage suggest its mechanism?	Deep basal ganglia, thalamic, pontine, and cerebellar bleeds commonly reflect hypertensive small-vessel damage, while lobar bleeding in an older adult raises cerebral amyloid angiopathy among other causes.

IMF-030-02-0008-en	How far do lateral tongue injury, postictal confusion, and urinary incontinence support a convulsive seizure?	Lateral tongue injury and prolonged postictal confusion support a convulsive seizure but are not mandatory, whereas urinary incontinence, like brief myoclonic jerks after syncope, is not specific.

IMF-030-02-0009-en	Why should status epilepticus receive an adequate benzodiazepine dose rather than repeated small doses?	Status is a failure of seizure termination that becomes progressively harder to stop, and repeated small doses delay definitive therapy.

IMF-030-02-0010-en	What trade-off accompanies hypertonic saline or mannitol in raised intracranial pressure?	They create an osmotic gradient, but each carries volume, sodium, renal, and haemodynamic consequences.

IMF-030-02-0011-en	What examination findings distinguish upper from lower motor-neuron weakness?	Upper motor-neuron disease gives increased tone, brisk reflexes, and pathological plantar responses after the acute phase, whereas lower motor-neuron disease gives reduced tone, wasting, fasciculation, and depressed reflexes.

IMF-030-02-0012-en	Why can limb strength and pulse oximetry mislead in Guillain-Barré syndrome?	Limb strength can underestimate respiratory decline and oximetry can stay normal until ventilatory failure is advanced, so vital capacity is tracked serially and bulbar weakness may mandate intubation before carbon dioxide rises.

IMF-030-02-0013-en	Which features suggest dementia with Lewy bodies, and which drug sensitivity matters clinically?	Fluctuation, recurrent visual hallucinations, rapid-eye-movement sleep behaviour disorder, and spontaneous parkinsonism; marked antipsychotic sensitivity is clinically important.

IMF-030-02-0014-en	Why should an abrupt stepwise decline not be attributed to the underlying neurodegeneration alone?	Infection, medicines, constipation, pain, sleep, dehydration, or new vascular injury may be responsible, and these must be sought.

IMF-031-01-0001-en	In what order does neurological diagnosis pose its two core questions, and why can incidental imaging not replace this reasoning?	It first asks where the lesion is, then what process produces it at that speed; coherent localisation guides testing, and an incidental imaging finding never replaces anatomy.

IMF-031-01-0002-en	How does a deficit that is maximal at onset differ in likely mechanism from one that evolves over hours to days?	Maximal deficit at onset suggests embolism, haemorrhage, seizure, migraine or trauma, whereas evolution over hours to days suggests inflammation, infection, infarct progression, metabolic disturbance or compression.

IMF-031-01-0003-en	Why should the clinician ask the patient to describe what failed rather than accept a label such as dizziness?	Labels are ambiguous: dizziness may mean vertigo, presyncope, imbalance or non-specific disequilibrium, and each points to a different mechanism and localisation.

IMF-031-01-0004-en	Which features of an episodic event should a witness description reconstruct?	Posture, prodrome, colour, eye and head movement, motor sequence, responsiveness, duration, injury, tongue biting, recovery and provoking circumstances.

IMF-031-01-0005-en	When red flags such as thunderclap headache, declining consciousness or spinal pain with sphincter disturbance are present, how does the order of assessment change?	Stabilisation and urgent treatment take priority over a leisurely complete examination, because these features signal immediately threatening disease.

IMF-031-01-0006-en	Why are arousal and attention assessed before memory, language and executive testing?	Impaired arousal or attention invalidates downstream cognitive testing, so poor performance on later tasks cannot be interpreted until these are established.

IMF-031-01-0007-en	From which conditions must aphasia be distinguished, and why does this matter?	From dysarthria, deafness, low arousal and language unfamiliarity, because each can mimic a language disorder without the lesion that aphasia implies.

IMF-031-01-0008-en	Why is decision-making capacity assessed for the specific decision rather than inferred from a diagnosis or screening score?	Scores are influenced by education, language, culture, sensory loss, distress, fatigue and disability, and neither a score nor a diagnosis shows whether the person can make this particular decision.

IMF-031-01-0009-en	What does a relative afferent pupillary defect indicate, and why is papilloedema an imperfect sign of raised pressure?	It indicates asymmetric retinal or optic-nerve dysfunction; papilloedema suggests raised pressure but is neither immediate nor universal, so its absence does not exclude it.

IMF-031-01-0011-en	Why does examination of palate, voice, cough and swallowing carry safety significance beyond localisation?	Lower cranial dysfunction can threaten the airway and nutrition, so poor secretion control or unsafe swallowing is a direct risk, not only a localising clue.

IMF-031-01-0012-en	How do spasticity, rigidity and paratonia differ when a relaxed joint is moved at different speeds?	Spasticity is velocity-dependent, rigidity is more uniform, and paratonia varies with the patient's cooperation or with frontal dysfunction.

IMF-031-01-0013-en	Which muscle groups are preferentially weak in pyramidal weakness, and how does this differ from root or nerve lesions?	Pyramidal weakness often affects upper-limb extensors and lower-limb flexors more than their opposites, whereas root and nerve lesions follow myotomal or named-nerve patterns.

IMF-031-01-0014-en	Which reflex findings support upper motor-neuron dysfunction, and why must reduced reflexes be interpreted cautiously?	Hyperreflexia, clonus and extensor plantar responses support it; reduced reflexes suggest lower motor-neuron, nerve or root disease or acute spinal shock but can be normal variants.

IMF-031-01-0015-en	Why are cortical sensory tests such as graphesthesia and stereognosis uninterpretable in some patients?	They require intact primary sensation and attention, so a deficit in either produces failure that does not reflect cortical sensory dysfunction.

IMF-031-01-0016-en	What do a sensory level, saddle loss and a stocking distribution each suggest?	A sensory level suggests spinal cord disease, saddle loss suggests cauda equina or conus involvement, and a stocking distribution suggests polyneuropathy.

IMF-031-01-0017-en	What does falling only when the eyes are closed on Romberg testing indicate, and why is it not a cerebellar test?	Removing vision exposes impaired proprioceptive or vestibular compensation; the test assesses maintaining stance without visual input, not cerebellar function in general.

IMF-031-01-0018-en	How do brainstem and cerebellar lesions differ in their pattern of signs?	Brainstem lesions often combine cranial-nerve signs with contralateral body findings, whereas cerebellar lesions produce ipsilateral coordination deficits, eye signs, dysarthria and gait disturbance without primary weakness.

IMF-031-01-0019-en	How do the motor signs of a spinal-cord lesion differ at its level and below it?	It produces segmental lower motor-neuron findings at the lesion and bilateral upper motor-neuron findings below it, possibly with sphincter dysfunction.

IMF-031-01-0021-en	How are neuromuscular-junction disease and myopathy distinguished from each other and from polyneuropathy?	Junction disease causes fatigable motor dysfunction and myopathy proximal weakness with reflexes often preserved until late, both without sensory loss, whereas polyneuropathy is usually length-dependent and symmetric.

IMF-031-01-0022-en	What does non-contrast computed tomography do well, and when is magnetic resonance preferred?	Computed tomography rapidly detects blood, mass effect, hydrocephalus and fractures; magnetic resonance gives superior contrast for infarction, demyelination, tumour, infection, posterior fossa, cord, nerve and muscle.

IMF-031-02-0001-en	Why is an opening summary such as sudden left-sided weakness and numbness with normal speech more useful than possible stroke?	It specifies failed function, distribution, onset and associated features, turning the narrative into a testable anatomical model rather than a diagnostic label.

IMF-031-02-0002-en	What distinguishes positive from negative neurological phenomena, and why is the distinction not absolute?	Positive phenomena suggest excessive or spreading neural activity and negative ones loss of function, but focal seizure may be followed by temporary weakness and transient ischaemia can occasionally produce positive symptoms.

IMF-031-02-0004-en	Why do convulsive movements alone not establish epilepsy, and which features raise the likelihood of seizure?	Briefly inadequate cerebral perfusion in syncope can cause them; prolonged post-event confusion, stereotyped focal onset, lateral tongue injury and sustained rhythmic motor activity favour seizure.

IMF-031-02-0005-en	Why is a documented change on serial examination often more informative than one elaborate assessment?	Signs evolve in conditions such as stroke, raised intracranial pressure, spinal compression, neuromuscular respiratory failure and delirium, and repetition separates a stable deficit from measurement noise.

IMF-031-02-0008-en	How do monocular loss, bitemporal loss and a homonymous defect localise along the visual pathway?	Monocular loss lies anterior to the chiasm, bitemporal loss suggests chiasmal disease, and a homonymous defect lies behind the chiasm on the contralateral side.

IMF-031-02-0009-en	Why does pupillary involvement matter in a third-nerve palsy, and why can sixth-nerve weakness mislead localisation?	Pupillary involvement raises concern for compression; sixth-nerve weakness limits abduction but may be a non-localising consequence of raised intracranial pressure.

IMF-031-02-0010-en	How do tongue findings distinguish lower motor-neuron disease from bilateral corticobulbar involvement?	Tongue wasting and fasciculation support lower motor-neuron disease, whereas slow spastic tongue movement with a brisk jaw reflex supports bilateral corticobulbar involvement.

IMF-031-02-0011-en	Why is normal oxygen saturation false reassurance in neuromuscular ventilatory failure, and what is monitored instead?	Saturation can stay preserved until carbon dioxide retention is advanced, so look for orthopnoea, weak cough, fewer words per breath, neck flexion weakness and paradoxical breathing, and measure forced vital capacity serially.

IMF-031-02-0013-en	Why should a spinal sensory level be checked from both directions, and why does a normal early examination not exclude cord disease?	The sensory level can lie below the structural lesion, and acute cord injury may first cause flaccidity and absent reflexes, so early normal reflexes do not refute an upper motor-neuron lesion.

IMF-032-01-0001-en	Why can musculoskeletal disease arise from failures other than the contractile machinery?	Function depends on muscle, motor control, matrix, bone, cartilage, synovium, tendons, vessels and nerves, so failure of connective tissue, mineralisation, perfusion, innervation, immune tolerance or mechanical adaptation can all cause disease.

IMF-032-01-0002-en	How does a sarcomere shorten even though its filaments do not shorten?	Actin slides past myosin through repeated cross-bridge cycling, so the sarcomere shortens while the thin and thick filaments keep their own length.

IMF-032-01-0003-en	What does adenosine triphosphate do in the cross-bridge cycle, and what happens in its absence?	Its binding releases myosin from actin and its hydrolysis recocks the myosin head; without it, cross-bridges cannot release and remain attached.

IMF-032-01-0004-en	Why does muscle force fall with both excessive shortening and excessive stretch?	Force depends on actin and myosin overlap, and both extremes reduce the number of productive cross-bridges that can form.

IMF-032-01-0005-en	What functional trade-off distinguishes parallel from pennate fibre architecture?	Parallel fibres permit greater excursion and speed, whereas pennate fibres pack more contractile material into a given volume and generate greater force; physiological cross-sectional area predicts force better than visible bulk.

IMF-032-01-0006-en	How does tendon compliance change the link between fibre shortening and joint movement?	A compliant tendon temporarily stores elastic energy, so fibre shortening and joint movement are no longer in a fixed relation.

IMF-032-01-0007-en	How does a muscle action potential lead to cross-bridge cycling?	It spreads along sarcolemma and transverse tubules, where voltage-sensitive proteins activate ryanodine receptors to release calcium from sarcoplasmic reticulum; calcium binds troponin C and moves tropomyosin off actin sites.

IMF-032-01-0008-en	Why does rapid repeated stimulation increase force until tetanus occurs?	Each stimulus arrives before calcium pumps have fully returned calcium to sarcoplasmic reticulum, so force summates, and sufficiently rapid stimulation produces tetanus.

IMF-032-01-0009-en	Why do slow oxidative fibres resist fatigue while fast glycolytic fibres do not?	Slow oxidative fibres have abundant mitochondria, myoglobin and capillaries and produce lower force economically, whereas fast glycolytic fibres generate high power but fatigue rapidly.

IMF-032-01-0010-en	How do energy systems supply adenosine triphosphate as activity lengthens?	Stored adenosine triphosphate lasts only briefly, phosphocreatine buffers it rapidly, anaerobic glycolysis gives fast substrate-level phosphorylation, and oxidative phosphorylation supplies most energy in sustained activity.

IMF-032-01-0011-en	Why is lactate not merely waste, and why does it not explain delayed soreness after eccentric exercise?	Lactate is a transferable fuel and gluconeogenic substrate; delayed soreness after unfamiliar eccentric exercise reflects microinjury and inflammation rather than retained lactate.

IMF-032-01-0014-en	How do resistance and endurance training differ in the adaptations they produce?	Resistance training first increases neural activation, then hypertrophy through protein synthesis and satellite cells; endurance training increases mitochondria, oxidative enzymes, capillaries and fuel handling, because adaptation is specific to demand.

IMF-032-01-0017-en	How do osteoblast-lineage cells, osteocytes and osteoclasts cooperate in remodelling?	Osteoblast-lineage cells make osteoid and coordinate mineralisation, osteocytes sense strain and signal through canaliculi, and osteoclasts resorb; coupling resorption to formation repairs microdamage and adjusts architecture.

IMF-032-01-0018-en	Why does bone mass alone not fully determine fracture risk?	Strength also depends on geometry, microarchitecture and material quality and on accumulated damage, and fracture additionally depends on falls.

IMF-032-01-0019-en	What distinguishes primary fracture healing from healing through callus?	Callus healing passes from haematoma and soft callus to hard woven-bone callus and remodelling; primary healing occurs with little callus across rigidly compressed, anatomically reduced surfaces.

IMF-032-01-0020-en	How do collagen and proteoglycans divide load-bearing in articular cartilage?	Type-two collagen resists shear and maintains shape, while negatively charged proteoglycans attract water and resist compression; loading expresses fluid and unloading lets it recover.

IMF-032-01-0021-en	Why is cartilage repair limited, and why does prolonged immobilisation harm it?	Cartilage is avascular and fed mainly by synovial fluid, which movement circulates; prolonged immobilisation removes this and weakens multiple joint tissues.

IMF-032-01-0022-en	Why does rest without graded reloading often fail in tendinopathy?	Tendinopathy reflects disordered matrix and load response, not simple inflammation alone, and matrix, which adapts more slowly than muscle, gains stiffness and capacity through progressive loading.

IMF-032-01-0023-en	Why does joint flexibility alone not establish an inherited connective-tissue syndrome?	Inherited matrix defects produce variable combinations of hypermobility, skin fragility, vascular risk, eye disease, bone weakness and organ dysfunction, so phenotype and family history guide genetic evaluation.

IMF-032-01-0024-en	Why must examination separate loss of force from other causes of perceived weakness?	Failure at different levels, including pain inhibition, stiffness, instability, fatigue and poor coordination, can all feel like weakness while needing different management.

IMF-032-02-0001-en	Why are motor units recruited from small low-threshold units toward large fast units?	This size principle keeps ordinary activity economical with fatigue-resistant units while preserving the high-force reserve of large units; rising discharge frequency then summates force.

IMF-032-02-0003-en	Why may a patient be able to lower a load they cannot lift?	In concentric shortening force falls as velocity rises because attachment time shrinks, whereas eccentrically lengthening muscle resists greater force at lower metabolic cost through cross-bridges and elastic proteins.

IMF-032-02-0004-en	Why is strength tested at one joint angle an incomplete measure for rehabilitation?	Joint torque is muscle force times a changing moment arm, altered further by tendon angle, co-contraction and passive tension, so one angle samples only one mechanical state.	Integrated Medical Foundations; chapter 32, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 41eeb620842aa1acb1f75c85a1789c1619a2ff5ed17e74c95b389b9d76e1fa54; editorial review pending	imf lang::en chapter::032 module::032-02 review::pending
IMF-032-02-0005-en	Why can power decline with ageing before manual strength grades change?	Power is force times shortening velocity, and ageing preferentially reduces fast motor units and type-two fibre area, which supply speed.

IMF-032-02-0006-en	Why are heart rate, breathlessness, repetitions, speed, force loss and recovery time recorded when a patient reports tiredness?	The same complaint covers different mechanisms, so these measures name the limiting system and allow recovery intervals to match it rather than a universal number.

IMF-032-02-0007-en	Why is weight-bearing permission not decided by the instruction to stop if it hurts?	Pain does not capture fracture pattern, fixation stability, bone quality, wound, infection, imaging, surgical restrictions or falls risk, so these are combined and loading progresses from below the point where gait deteriorates.	Integrated Medical Foundations; chapter 32, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 41eeb620842aa1acb1f75c85a1789c1619a2ff5ed17e74c95b389b9d76e1fa54; editorial review pending	imf lang::en chapter::032 module::032-02 review::pending
IMF-032-02-0008-en	Why can bone of apparently adequate density still be weak?	Toughness needs collagen and mineral together: defective collagen or excessive mineralisation lowers it, and trabecular perforation weakens structure beyond mineral loss, which density does not directly measure.	Integrated Medical Foundations; chapter 32, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 41eeb620842aa1acb1f75c85a1789c1619a2ff5ed17e74c95b389b9d76e1fa54; editorial review pending	imf lang::en chapter::032 module::032-02 review::pending
IMF-032-02-0009-en	How does dynamic loading promote bone formation, and why is rest between bouts useful?	Strain-driven canalicular fluid flow lowers sclerostin and other inhibitory signals; the response saturates with repeated cycles, and rest restores mechanosensitivity and permits repair.	Integrated Medical Foundations; chapter 32, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 41eeb620842aa1acb1f75c85a1789c1619a2ff5ed17e74c95b389b9d76e1fa54; editorial review pending	imf lang::en chapter::032 module::032-02 review::pending
IMF-032-02-0010-en	Why can an increase in bone remodelling temporarily reduce strength?	Resorption precedes refilling, so higher turnover creates temporary spaces that weaken bone if formation does not catch up, as in oestrogen deficiency with increased turnover and uncoupling.	Integrated Medical Foundations; chapter 32, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 41eeb620842aa1acb1f75c85a1789c1619a2ff5ed17e74c95b389b9d76e1fa54; editorial review pending	imf lang::en chapter::032 module::032-02 review::pending
IMF-032-02-0011-en	How does the degree of fracture stability determine the pattern of repair?	Relative stability permits callus that bridges the fracture, absolute stability across precisely reduced surfaces allows direct remodelling, and too much motion disrupts vascular ingrowth and mineralisation.

IMF-032-02-0012-en	Why can joint swelling cause weakness out of proportion to muscle loss?	Joint swelling itself inhibits activation of surrounding muscle, particularly the quadriceps, producing weakness beyond structural muscle loss.	Integrated Medical Foundations; chapter 32, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 41eeb620842aa1acb1f75c85a1789c1619a2ff5ed17e74c95b389b9d76e1fa54; editorial review pending	imf lang::en chapter::032 module::032-02 review::pending
IMF-032-02-0013-en	Why is tendon pain managed with progressive loading rather than complete rest or imaging?	Pain does not gauge structural damage and imaging abnormalities occur without symptoms; complete rest reduces capacity, so symptom-guided loading restores force tolerance, then speed and energy storage.

IMF-032-02-0014-en	Why does exercise prescription aim to build reserve rather than tolerance of the clinic exercise?	Enough reserve makes ordinary life a smaller fraction of maximum capacity, leaving room for perturbation, fatigue and ageing without crossing the threshold into failure.

IMF-033-01-0001-en	Which two distinctions come first when sorting musculoskeletal symptoms, and why is the first one prioritised?	First urgent versus non-urgent, because threatened limb, open fracture, compartment syndrome, septic joint, spinal compression and systemic vasculitis cannot wait; then inflammatory versus predominantly mechanical disease.

IMF-033-01-0002-en	Why does soft-tissue injury need a balance between protection and movement rather than maximal immobilisation?	Too little protection permits repeated disruption, but prolonged immobilisation causes stiffness, atrophy, reduced matrix capacity, thrombosis and delayed return.

IMF-033-01-0003-en	How do the inflammatory, proliferative and remodelling phases each contribute to soft-tissue repair?	Inflammation clears debris and recruits repair cells, proliferation creates new matrix, and remodelling aligns the tissue with the load it carries.

IMF-033-01-0004-en	Cold, compression, elevation and analgesia relieve an acute soft-tissue injury. What determines definitive care, and what suits many stable injuries?	Definitive care depends on the injured tissue and its severity, not on symptom relief; many stable injuries do best with early protected movement and progressive loading.

IMF-033-01-0005-en	Why should modest pain not reassure the examiner when tendon rupture is possible?	Rupture may cause surprisingly little pain yet still produce a palpable gap, altered contour, weakness and loss of a normal mechanical test, so function must be examined.

IMF-033-01-0006-en	What distinguishes a low-energy fragility fracture from a pathological fracture in what it implies about the bone?	A fragility fracture implies generally reduced bone strength, whereas a pathological fracture occurs through a focal disease process in the bone.

IMF-033-01-0007-en	Why does an open fracture need urgent antibiotics, tetanus assessment and surgical debridement?	Because the fracture communicates with the environment; it also needs sterile coverage and stabilisation, and the wound should not be repeatedly probed.

IMF-033-01-0008-en	An early radiograph looks normal but focal bony signs persist. How should this be managed, and why?	Immobilise and repeat or advance the imaging, because apparently normal early radiographs can miss occult fractures.

IMF-033-01-0009-en	Why can compartment syndrome be present while distal pulses remain palpable?	The problem is raised pressure inside a closed fascial space impairing tissue perfusion, not major arterial occlusion, so pain out of proportion, pain on passive stretch, tense swelling and neurological change are the warnings.

IMF-033-01-0011-en	Why is osteoarthritis described as whole-joint failure rather than simple cartilage wear?	It involves cartilage, subchondral bone, synovium, ligaments, capsule and muscle, with attempted repair, osteophytes, bone remodelling and intermittent synovitis accompanying cartilage loss.

IMF-033-01-0012-en	Which features of joint pain argue against osteoarthritis and suggest another process?	Osteoarthritis typically causes activity-related pain with brief stiffness after rest, so marked inflammation, prolonged morning stiffness, systemic features or an unusual distribution suggest something else.

IMF-033-01-0014-en	Why does neither a normal serum urate nor the finding of urate crystals settle the diagnosis of an acute hot joint?	Serum urate can be normal during a gout flare, and needle-shaped negatively birefringent crystals support gout but do not exclude concurrent infection.

IMF-033-01-0018-en	Why does chronic osteomyelitis need source control rather than antimicrobials alone?	Chronic disease may form necrotic bone, sinus tracts and biofilm, so treatment combines source control, targeted antimicrobials guided by deep-tissue or bone microbiology, perfusion and pressure management, and stabilisation.

IMF-033-01-0019-en	What does a positive anti-citrullinated-peptide antibody add in suspected rheumatoid arthritis, and what does a negative result fail to do?	It is more specific than rheumatoid factor and may predict erosive disease, but negative antibodies or normal markers do not exclude clinical synovitis.

IMF-033-01-0020-en	Why is rheumatoid arthritis treated early with disease-modifying drugs aiming at remission rather than with analgesia?	Immune-mediated synovitis can destroy cartilage, bone, tendon and ligament, and early disease-modifying treatment improves long-term outcome; the aim is remission or low activity.

IMF-033-01-0021-en	How does inflammatory back pain of spondyloarthritis differ from typical degenerative back pain, and where does HLA-B27 fit?	It often improves with movement, disturbs the second half of the night and begins younger; HLA-B27 supports risk in context but is not diagnostic.

IMF-033-01-0022-en	Why is a positive antinuclear antibody alone insufficient to establish lupus likelihood or activity?	It is sensitive but poorly specific, so more specific antibodies, complement, blood counts, urine sediment, protein excretion, kidney function and phenotype are needed.

IMF-033-01-0023-en	In suspected vasculitis, what role do autoantibodies play compared with biopsy or vascular imaging?	Autoantibodies support the diagnosis but do not replace the clinical phenotype, whereas biopsy or vascular imaging often establishes it.

IMF-033-01-0024-en	Why should immune therapy not be reflexively escalated when an immunosuppressed patient develops fever?	Fever may reflect infection, disease flare or both, so dangerous infection must be excluded before escalating immunosuppression.

IMF-033-02-0001-en	How does comparing pain on active and passive movement help localise the painful structure, and what limits this?	Pain on active but not passive movement suggests contractile tissue, pain through passive range suggests joint or capsule, but guarding and severe pain blur the distinction.

IMF-033-02-0002-en	How does joint distribution discriminate rheumatoid arthritis, psoriatic arthritis, gout and spondyloarthritis?	Symmetric metacarpophalangeal and proximal interphalangeal synovitis suggests rheumatoid arthritis, distal interphalangeal disease with nail change psoriatic arthritis, abrupt first metatarsophalangeal inflammation gout, and axial or entheseal disease spondyloarthritis.

IMF-033-02-0003-en	After limb trauma the limb is warm and pink. Why can important arterial injury still be present?	Collateral flow can keep the limb warm and pink, so asymmetry, expanding haematoma, bruit, neurological deficit or mechanism can still mandate vascular imaging or exploration.

IMF-033-02-0004-en	What sequence of pressure failure leads from a tight fascial compartment to nerve and muscle ischaemia?	Venous outflow fails first, which raises interstitial pressure further until capillary flow and nerve conduction decline.

IMF-033-02-0005-en	Why can neither synovial-fluid leukocyte count nor a negative Gram stain rule out septic arthritis?	Fluid appearance and leukocyte count overlap among bacterial, crystal and immune arthritis, and Gram stain lacks the sensitivity to exclude infection.

IMF-033-02-0006-en	Why does osteoarthritis pain correlate poorly with radiographic change?	Cartilage itself lacks nerves, so pain arises from innervated bone, synovium, capsule, tendon and sensitised neural pathways rather than from the cartilage loss seen on imaging.

IMF-033-02-0007-en	Why does starting urate-lowering therapy often provoke early gout flares, and how is premature abandonment prevented?	Effective urate lowering gradually dissolves deposits, and starting it mobilises them, provoking flares; prophylaxis and explanation prevent the patient stopping too early.

IMF-033-02-0008-en	In rheumatoid arthritis, pain persists although swelling and inflammation have resolved. Why is further immunosuppression alone not the answer?	Residual pain may come from fibromyalgia, structural damage, tendon disorder, mood or sleep rather than active synovitis, so these deserve consideration.

IMF-033-02-0009-en	Why is urine examination essential in systemic lupus erythematosus even without renal symptoms?	Lupus nephritis may be clinically quiet, so proteinuria and active sediment must be sought directly.

IMF-033-02-0010-en	In scleroderma renal crisis, why is rapid angiotensin-converting-enzyme inhibition continued even as creatinine rises?	Abrupt hypertension with kidney injury defines the crisis, and rapid angiotensin-converting-enzyme inhibition is the central treatment despite rising creatinine.

IMF-033-02-0011-en	Why is suspected giant-cell arteritis with visual threat treated before biopsy, unlike most vasculitis?	Biopsy is usually obtained before prolonged immunosuppression, but waiting for it in giant-cell arteritis with visual threat can cost sight.

IMF-033-02-0013-en	A patient on immunosuppression develops new breathlessness with little fever and low inflammatory markers. Why is infection not excluded?	Scant fever and low markers are not grounds for reassurance, so disease-related lung involvement, opportunistic infection, drug-induced lung injury, thrombosis and heart failure are considered in parallel.

IMF-034-01-0001-en	Why should a skin eruption be described before it is named?	Dermatological diagnosis relies on morphology and distribution, so an accurate description of what is seen must come before the diagnostic label.

IMF-034-01-0002-en	How does the epidermis build a water-resistant barrier, and what follows when it is disrupted?	Basal cells proliferate, migrate outward, make keratin and lipids and flatten into corneocytes set in lipid layers; disruption increases water loss and lets irritants, allergens and pathogens enter.

IMF-034-01-0003-en	What mainly determines differences in skin colour, and how does melanin protect the skin?	Colour differences mainly reflect melanosome activity and distribution rather than melanocyte number; melanin transferred to keratinocytes absorbs ultraviolet radiation and limits DNA damage.

IMF-034-01-0004-en	How does the skin increase or reduce heat loss, and what mainly controls eccrine sweating?	Cutaneous vasodilation transfers core heat to the environment and vasoconstriction conserves it; eccrine sweat cools by evaporation under mainly sympathetic cholinergic control.

IMF-034-01-0008-en	Why is food avoidance without evidence discouraged in atopic dermatitis, and what does management rely on instead?	Unsupported food avoidance can cause nutritional harm; management uses emollients, irritant avoidance, topical anti-inflammatory therapy, infection treatment when present, and escalation for severe disease.

IMF-034-01-0014-en	What distribution does varicella-zoster reactivation follow, and why is early antiviral treatment important in high-risk sites and hosts?	It follows a sensory distribution and can cause persistent neuralgia, eye disease, ear-facial syndromes or dissemination, so early antivirals matter where these risks are high.

IMF-034-01-0016-en	How do keratinocytes, fibroblasts, angiogenesis and contraction each contribute to wound healing?	Keratinocytes close the surface, fibroblasts deposit matrix, angiogenesis supplies granulation tissue, and contraction reduces area; scar strength rises for months but never matches uninjured skin.

IMF-034-02-0002-en	Why are bland emollients and avoidance of harsh cleansers mechanistic rather than cosmetic treatments?	Barrier damage raises transepidermal water loss and admits irritants and antigens, provoking inflammation that further damages the barrier; these measures break that loop.

IMF-034-02-0003-en	Why does the same topical corticosteroid carry more risk on eyelid or intertriginous skin than on the palms?	Thin eyelid, facial, genital and intertriginous skin absorbs more drug than palms or soles and is more vulnerable to corticosteroid atrophy.

IMF-034-02-0004-en	In atopic dermatitis, what does and does not indicate infection, and which pattern demands urgent antiviral treatment?	Weeping or crusting alone does not prove bacterial infection, whereas spreading pain, pustules, fever or systemic illness raise concern; monomorphic painful punched-out erosions suggest eczema herpeticum.

IMF-034-02-0008-en	Why can necrotising soft-tissue infection look modest early, and why are antibiotics alone insufficient?	Destruction progresses deep along fascia, so skin findings lag; antibiotics cannot adequately penetrate and control devitalised tissue, so exploration and debridement are diagnostic and therapeutic.

IMF-034-02-0010-en	Why can deep muscle be injured by pressure before the epidermis breaks down?	Pressure injury arises from prolonged deformation, shear and impaired reperfusion, and tissue strains over bone differ, so deep muscle may be injured first.

IMF-034-02-0013-en	Why is excision biopsy preferred for a suspicious pigmented lesion, even when dermoscopy is available?	Dermoscopy improves discrimination but does not replace biopsy; excision preserves architecture and allows Breslow thickness to be measured, which guides staging and margins.

IMF-035-01-0022-en	How does quorum sensing let bacteria coordinate virulence?	Secreted signals let bacteria estimate local population density, and this estimate can regulate biofilm formation and virulence.

IMF-035-01-0023-en	Why does finding dysbiosis not establish that altered microbiota caused a disease?	Dysbiosis describes alteration, not a proven mechanism; associations require control for confounding, and interventions require demonstrated benefit.

IMF-035-02-0001-en	Why does active bacterial growth matter for killing by wall-active drugs?	Wall-active drugs weaken the peptidoglycan structure as it expands, so active growth is important for killing.

IMF-035-02-0002-en	How can porin changes in Gram-negative bacteria combine with beta-lactamases to create substantial resistance?	Porins restrict drug entry by size and chemistry, so their loss or alteration reduces entry while periplasmic enzymes further reduce intracellular drug exposure.

IMF-035-02-0003-en	Why is encapsulated bloodstream infection particularly dangerous when splenic function is absent?	Capsules and surface polysaccharides inhibit complement deposition and phagocytosis, so efficient clearance depends on opsonising antibody, which is less effective without splenic function.

IMF-035-02-0004-en	Why can infection relapse from a protected site even when the laboratory reported the organism as susceptible?	The result came from rapidly growing cells, but persister cells survive as transient phenotypic survivors without genetic resistance, and their descendants may again be susceptible.

IMF-035-02-0005-en	Why can source control or device removal be decisive in biofilm infection?	The matrix limits immune access and diffusion, so antibiotics may suppress planktonic shedding without sterilising the adherent reservoir.

IMF-035-02-0006-en	When fever or bacteraemia persists during antibiotic treatment, what should be reassessed before changing the drug, and why?	An uncontrolled source and drug delivery, because drainage, relief of obstruction or debridement may be needed rather than a different drug.

IMF-035-02-0007-en	Why must negative-sense RNA viruses carry or produce an RNA-dependent RNA polymerase, unlike many positive-sense viruses?	Positive-sense RNA can often function directly as messenger RNA, whereas negative-sense RNA cannot, so the polymerase is needed to produce messenger RNA.

IMF-035-02-0009-en	Why does viral evolution not guarantee reduced virulence over time?	Evolution has no intention: selection enriches variants that reproduce and transmit, and severity results from replication, transmission route, host immunity and ecological opportunity.

IMF-035-02-0012-en	Why should exposure history be taken before immune therapy in people from endemic settings?	Strongyloides can maintain infection through autoinfection for decades, and corticosteroid or other immunosuppression can trigger accelerated dissemination and secondary bacterial sepsis.

IMF-035-02-0014-en	What findings strengthen the case that a detected microbe is causing disease rather than merely present?	Finding it at the diseased site, burden fitting the syndrome, tissue invasion or characteristic injury, aligned host risk and timing, and weaker alternative causes.

IMF-036-01-0001-en	Why does detecting an organism in a sample not by itself establish that it caused the patient's illness?	Exposure does not guarantee colonisation, colonisation does not guarantee disease, and detection does not guarantee causation, so the result must be linked to organism, site, burden, host, timing, syndrome, and test performance.

IMF-036-01-0003-en	How do the incubation period and the latent period differ, and why can a person transmit infection without symptoms?	Incubation ends when symptoms begin, whereas latency ends when infectiousness begins, so communicability may precede symptoms or persist after recovery.

IMF-036-01-0008-en	Why is virulence described as relative, and how can host damage arise from both too little and too much defence?	A factor useful in one tissue may be irrelevant elsewhere, and opportunists cause severe disease when host defences change; damage can reflect deficient defence or an excessive, misdirected response.

Integrated Medical Foundations; chapter 36, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 0cf2141590ebc966d5940534608ff1aa93f0751733dec61575ff7c6a660f318f; editorial review pending	imf lang::en chapter::036 module::036-01 review::pending
IMF-036-02-0001-en	Why does viewing infection as a causal chain matter both for prevention and for interpreting a positive assay?	Disease needs every link from reservoir to host damage, so breaking any link prevents it, and a positive assay is only one element to integrate with exposure, site, host, burden, and timing.

IMF-036-02-0002-en	Why is respiratory spread better treated as a particle-size continuum than as two separate categories?	Large wet particles settle quickly while smaller aerosols stay suspended and accumulate in poorly ventilated rooms, so dose depends on distance, time, airflow, activity, masks, filtration, and inactivation.

IMF-036-02-0003-en	Why is an infectious dose conditional rather than a fixed number?	Fewer organisms can establish disease when delivered directly into tissue or when local defences such as gastric acid, ciliary clearance, urine flow, or intact skin are lost.

IMF-036-02-0004-en	Why does a virulence factor produce disease only in context, as shown by the capsule and acid tolerance?	Each trait helps in a particular niche: a capsule is especially valuable in blood, whereas acid tolerance matters during gastric passage, and some factors raise persistence without acute tissue destruction.

IMF-036-02-0005-en	Why can clinical improvement lag behind microbial killing?	Host injury can be immune-driven as well as microbe-driven, and inflammatory mediators and damaged tissue need time to resolve even after the organisms have died.

IMF-036-02-0006-en	Why do correlates of vaccine protection differ between types of immune memory?	Each acts at a different step: circulating antibody may prevent invasion, mucosal antibody may reduce entry, and T-cell memory may chiefly prevent severe disease.

IMF-036-02-0007-en	How do T-cell deficiency and asplenia differ in the infections they favour, and why?	T-cell deficiency permits opportunistic viruses, fungi, mycobacteria, and protozoa and weakens granulomas, whereas asplenia impairs clearance of opsonised encapsulated organisms and infected erythrocytes.

IMF-036-02-0008-en	Why is recording 'immune suppression' inadequate, and what makes slight inflammation a warning sign?	Each biological agent blocks different cytokine and cellular pathways, so drugs, doses, dates, and counts must be recorded; inflammation slight relative to illness severity itself suggests dangerous infection.

IMF-036-02-0009-en	Why may saliva-contaminated sputum in pneumonia, or a surface ulcer swab in osteomyelitis, mislead?	A specimen is a physical sample of the diagnostic hypothesis, and these samples reflect oral flora or surface organisms rather than alveolar or bone infection.

IMF-036-02-0010-en	Why do blood culture volume and separate venepunctures matter?	Bloodstream organisms may be sparse, so adequate volume often improves yield more than repeated low-volume sets, and separate venepunctures help distinguish contamination and assess persistence.

IMF-036-02-0011-en	Why does the sensitivity of nucleic-acid amplification create interpretive problems, and when is a negative result useful?	It also detects colonisation, latent carriage, transient passage, contamination, and dead organisms; a negative helps only if sampling was at the right site and time and the assay covers the variant.

IMF-036-02-0012-en	Why can a highly specific test produce more false than true positives in a low-risk patient?	Predictive values depend on pretest probability, so when a test is used broadly where disease is unlikely, false positives can outnumber true positives.

IMF-036-02-0013-en	Why does a 'susceptible' result not guarantee success at every infection site?	Urine, blood, cerebrospinal fluid, bone, lung, and intracellular compartments reach different free drug concentrations, and inoculum, abscess acidity, foreign material, biofilm, and source control are not reproduced on a plate.

IMF-036-02-0014-en	Why should a microbiology statement separate observation from inference, as with a skin organism in blood cultures?	One low-volume bottle is compatible with contamination, but persistent growth in several sets with an intravascular device may be true bacteraemia; explicit reasoning prevents both dismissal and overtreatment.

IMF-037-01-0001-en	Which four conditions must all hold for antimicrobial therapy to succeed?	An active drug must reach the site at sufficient exposure, the pathogen must be vulnerable, source control must occur, and host defence must complete clearance.

IMF-037-01-0002-en	Why does selective toxicity of antimicrobials remain only relative?	Mitochondria resemble bacterial ancestors, fungi are eukaryotic, and parasites share many human pathways, so substantial toxicity to human cells remains.

IMF-037-01-0003-en	How do pharmacokinetics and pharmacodynamics differ, and which exposure indices link them to antibacterial killing?	Pharmacokinetics sets concentration over time, while pharmacodynamics relates exposure to killing, via time of free drug above the minimum inhibitory concentration, peak relative to it, or total area under the curve.

IMF-037-01-0004-en	Why does the bactericidal versus bacteriostatic distinction not rank clinical effectiveness?	The distinction varies with organism, exposure, and method, and bacteriostatic drugs work by inhibiting growth while immune clearance completes the job.

IMF-037-01-0005-en	How do beta-lactams kill bacteria, and what kind of pharmacodynamic activity do they generally show?	They bind penicillin-binding proteins and disrupt peptidoglycan cross-linking, and their activity is generally time-dependent.

IMF-037-01-0006-en	Why is careful evaluation of a beta-lactam allergy label clinically valuable?	Labels are often inaccurate, and history and testing that separate immediate anaphylaxis from delayed benign rash or severe immune reactions can restore safer narrow options.

IMF-037-01-0007-en	Why does adding a beta-lactamase inhibitor not guarantee activity against a resistant organism?	Inhibitors protect selected partners but do not inhibit every enzyme, and extended-spectrum enzymes, AmpC, and carbapenemases have different implications, so susceptibility results and site guide therapy.

IMF-037-01-0008-en	Why is vancomycin exposure monitored in serious infection, and why can oral vancomycin not treat systemic infection?	Monitoring balances efficacy against kidney toxicity, and oral vancomycin acts within the gut rather than reaching systemic infection.

IMF-037-01-0009-en	Why are aminoglycosides active against aerobic Gram-negative organisms but not anaerobes?	They must be taken up by an oxygen-dependent mechanism before binding the thirty-S subunit to cause mistranslation, and anaerobes cannot provide that uptake.

IMF-037-02-0003-en	Why do aminoglycosides suit large separated doses in suitable patients?	Their killing relies substantially on a high peak relative to the inhibitory concentration, and a post-antibiotic effect persists between doses.

IMF-037-02-0004-en	In critical illness with renal failure, why may a full loading dose still be needed?	Capillary leak and resuscitation expand the distribution volume of hydrophilic drugs, and the loading dose depends mainly on distribution, while clearance governs only maintenance dosing.

IMF-037-02-0005-en	Why does nitrofurantoin treat lower urinary infection but not pyelonephritis or sepsis?	Urine can reach very high concentrations even when tissue levels are modest, so the drug must match the infected compartment rather than the culture source.

IMF-037-02-0006-en	How should a beta-lactam reaction history separate intolerance, a remote mild rash, and dangerous reactions?	Isolated gastrointestinal upset is intolerance, not allergy; a remote mild rash differs from immediate urticaria, bronchospasm, hypotension, or severe delayed syndromes, and severe immune reactions are not challenged casually.

IMF-037-02-0013-en	Why should treatment failure prompt structured review rather than reflexive broadening?	Failure may reflect a non-infectious syndrome, wrong sampling, missed doses, or undrained pus or foreign material, and broader therapy adds toxicity while delaying the needed procedure.

IMF-037-02-0014-en	When is conversion from intravenous to oral therapy appropriate, and why is intravenous access not inherently stronger?	Convert when a bioavailable active drug reaches the site and the patient can absorb it, because efficacy depends on exposure at the site rather than on route.

IMF-038-01-0001-en	Why is sepsis defined as a syndrome rather than a culture result, and what does this imply about fever and hypotension?	Sepsis is life-threatening organ dysfunction from a dysregulated response to infection, so it is identified by that dysfunction and may occur without fever or hypotension.

IMF-038-01-0002-en	What distinguishes antimicrobial stewardship from simply giving weaker treatment?	Stewardship is disciplined selection, optimisation, narrowing, and stopping of antimicrobials, aiming for the best outcome rather than less effective therapy.

IMF-038-01-0003-en	How can the host response in sepsis cause both tissue damage and immune exhaustion?	Pro-inflammatory and anti-inflammatory signals occur simultaneously, so injurious inflammation and immune exhaustion can coexist in the same patient.

IMF-038-01-0004-en	Why can an apparently adequate blood pressure coexist with impaired tissue perfusion in sepsis?	Microcirculatory shunting diverts flow away from tissues, so global pressure may look adequate while cells remain underperfused.

IMF-038-01-0005-en	Why is serum lactate a risk marker rather than a direct meter of oxygen debt, and how should a persistent rise be handled?	Lactate also rises from adrenergic glycolysis, reduced clearance, drugs, and seizures, so a persistent rise demands renewed assessment rather than automatic fluid.

IMF-038-01-0006-en	How can neutropenia and beta blockade make sepsis harder to recognise?	Neutropenia can blunt local inflammation and beta blockade can blunt tachycardia, removing signs that would normally reveal infection or deterioration.

IMF-038-01-0007-en	Why must the assessment of suspected sepsis include a search for non-infectious mimics, and which are named?	Scores do not replace judgement, and haemorrhage, pancreatitis, pulmonary embolism, adrenal crisis, anaphylaxis, toxic ingestion, drug reaction, infarction, and inflammatory disease can resemble it.

IMF-038-01-0008-en	How is septic shock operationalised, and why should treatment not wait for formal criteria?	It is commonly taken as vasopressor need to maintain pressure with elevated lactate despite adequate volume assessment, but failing perfusion requires action before criteria are met.

IMF-038-01-0011-en	Why is antimicrobial timing governed by proportional urgency rather than one clock for every suspected infection?	Shock or likely severe infection needs urgent active therapy after rapid cultures, whereas in stable uncertain cases focused investigation reduces unnecessary exposure without compromising safety.

IMF-038-01-0012-en	Why may a full loading dose be needed in sepsis even when the kidneys are failing?	Sepsis expands the volume of distribution and alters protein binding and clearance, so the initial dose must fill a larger space regardless of renal dysfunction.

IMF-038-01-0013-en	Why does clinical improvement not confirm the original diagnosis, and what can deterioration on therapy reflect?	Improvement proves nothing retrospectively, and deterioration may reflect resistance, inadequate exposure, the wrong source, immune injury, or non-infectious disease.

IMF-038-01-0014-en	Why are fixed large fluid volumes risky in sepsis, and what guides further fluid better than static pressure?	They can harm patients with limited cardiac or renal reserve; passive-leg-raise response, capillary refill, urine output, mentation, and echocardiography guide further fluid better.

IMF-038-01-0015-en	Which vasopressor is usually first for distributive shock, and when are corticosteroids considered?	Norepinephrine is the usual first vasopressor; corticosteroids are considered in vasopressor-dependent shock, not as routine treatment for every infection.

IMF-038-01-0016-en	Why can antibiotics alone fail in sepsis, and what should failure to improve after treatment prompt?	Antibiotics cannot drain pus, remove necrosis, relieve obstruction, or sterilise many foreign bodies; failure to improve requires another search for collections, devitalised tissue, device infection, or a second source.

IMF-038-01-0018-en	What determines antimicrobial duration, and why is automatic extension for persistent radiographic change harmful?	Duration follows syndrome, source control, immune status, response, and evidence; persistent imaging change or nonspecific inflammation does not itself indicate ongoing infection, so extending for it adds harm.

IMF-038-01-0021-en	Why does every invasive device need a continuing indication, and does a surgical drain justify continued prophylaxis?	Every invasive device breaches host defence, so it must be reviewed and removed when no longer needed; a drain alone does not justify continued prophylaxis.

IMF-038-02-0004-en	Why do trajectory and reserve matter more than a single organ-dysfunction score in sepsis?	Failure of one organ increases the demand on others, so the direction of change and remaining reserve predict course better than one snapshot.

IMF-038-02-0005-en	Why can lactate rise even when oxygen is present, and why is forcing its normalisation with fluid harmful?	Adrenergic stimulation accelerates glycolysis and lactate production regardless of oxygen; chasing normal values with repeated fluid can cause pulmonary oedema and abdominal or venous congestion.

IMF-038-02-0006-en	Why is initial fluid framed as a therapeutic trial, and why may a fluid-responsive patient still not need fluid?	Each amount is tested against stroke volume, perfusion, and congestion; responsiveness is not need if perfusion is already adequate or pulmonary risk outweighs benefit.

IMF-038-02-0007-en	What makes passive leg raising more useful than static central venous pressure for predicting fluid responsiveness?	Passive leg raising gives a reversible internal volume challenge when paired with a responsive output marker, whereas static central venous pressure poorly predicts responsiveness.

IMF-038-02-0008-en	Why should a rising vasopressor requirement not be read as simple underdosing?	It may signal ongoing haemorrhage, tamponade, tension pneumothorax, pulmonary embolism, adrenal insufficiency, a persisting infective source, or acidaemia, each needing specific reassessment.

IMF-038-02-0009-en	How do poorly filled blood culture bottles and contamination each cause harm, and what does diagnostic stewardship mean?	Underfilling reduces sensitivity and contamination increases unnecessary therapy; diagnostic stewardship means taking the right specimen before treatment when safe, not withholding tests indiscriminately.

IMF-038-02-0010-en	Why does delayed source control allow sepsis to progress despite adequate serum antibiotic levels, and why take deep samples?	An undrained focus sustains microbial growth, toxin production, and inflammatory signalling; deep operative samples are taken because superficial swabs can misdirect therapy.

IMF-038-02-0011-en	In what sense does stewardship protect the treated patient first, beyond limiting resistance?	Avoiding unnecessary antimicrobials reduces allergy, kidney and liver injury, cytopenia, cardiac effects, interactions, C. difficile disease, and microbiota disruption in that patient.

IMF-038-02-0012-en	Why do pyuria and cloudy or odorous urine not justify treating bacteriuria in a catheterised patient?	Bacteria commonly inhabit catheterised tracts without disease, pyuria is common, and urine appearance is nonspecific; treatment without compatible symptoms causes adverse effects and resistance.

IMF-038-02-0014-en	Why do critical, semicritical, and noncritical devices need different processing?	Risk follows contact: devices entering sterile tissue need sterilisation, those contacting mucosa need validated high-level processing, and those touching intact skin need lower-level disinfection.

IMF-039-01-0001-en	Why is an abnormal blood count not a diagnosis, and what establishes the mechanism?	An abnormal count may reflect altered production, maturation, release, distribution, consumption, destruction, or clonal expansion, so morphology, lineage, tempo, symptoms, organ enlargement, and molecular findings establish mechanism.

IMF-039-01-0002-en	What distinguishes clonal haematopoiesis from leukaemia, and why is progression not inevitable?	A stem-cell mutation expands without diagnostic malignancy; it can raise future blood-cancer and cardiovascular risk, but additional genetic, epigenetic, and environmental changes shape progression.

IMF-039-01-0005-en	In lymphocytosis, how does the appearance of the cells help separate reactive from malignant causes?	Atypical reactive lymphocytes, as seen with viral infection, differ from a monomorphic malignant population, which suggests lymphoid neoplasia.

IMF-039-01-0006-en	Why should a persistent low white count be reviewed as a trend alongside the other lineages?	Trends and coexisting anaemia or thrombocytopenia reveal whether one lineage or the whole marrow is affected, and persistent abnormalities should never be dismissed without trend review.

IMF-039-01-0007-en	What determines infection risk in neutropenia, and why can a serious infection be missed?	Risk rises with the depth and duration of neutropenia and with skin, mucosal, device, and cellular-immune defects; profound neutropenia can produce serious infection without pus, focal signs, or fever.

IMF-039-01-0008-en	Why is fever during significant neutropenia handled as an emergency, and what is the first response?	Infection can progress without the usual signs, so cultures are taken, skin, mouth, lungs, abdomen, perineum, devices, and neurological state are assessed, and broad antipseudomonal antibiotics are given promptly.

IMF-039-01-0010-en	What can granulocyte colony-stimulating factor do in neutropenia, and what can it not replace?	It prevents or shortens selected treatment-related neutropenia, with bone pain and rare splenic or pulmonary complications, but it does not substitute for antimicrobial treatment in established sepsis.

IMF-039-01-0015-en	How does the output of myeloproliferative neoplasms differ from that of myelodysplastic neoplasms, as shown by polycythaemia vera?	Myeloproliferative neoplasms overproduce mature myeloid cells; polycythaemia vera expands red cells and often leukocytes and platelets, causing thrombosis, microvascular symptoms, itch, and splenomegaly.

IMF-039-02-0006-en	How does marrow infiltration produce a leukoerythroblastic film?	Leukaemia, lymphoma, fibrosis, granuloma, or metastatic cancer infiltrating the marrow releases nucleated red cells and immature myeloid cells into the blood.

IMF-039-02-0007-en	Why must marrow molecular findings be interpreted together with morphology?	Age-related clonal haematopoiesis can produce mutations without diagnostic cancer, so a mutation alone does not establish malignancy.

IMF-039-02-0008-en	What can cause a dry tap, and how should a negative result from an inadequate specimen be treated?	Fibrosis or densely packed disease can prevent aspiration; a negative result from an inadequate specimen is not absence of disease, so repeat sampling or another site is considered.

IMF-039-02-0010-en	Why is acute promyelocytic leukaemia uniquely urgent, and why is the platelet count alone an inadequate bleeding guide?	Abnormal promyelocytes activate coagulation and fibrinolysis, causing catastrophic bleeding, so bleeding risk must be read with clotting factors, fibrinogen, and repeated coagulation tests.

IMF-039-02-0011-en	How does hyperleukocytosis become leukostasis, and why can leukapheresis not stand alone?	Poorly deformable cells obstruct and activate microvasculature, mainly in lung and brain; leukapheresis has selected roles but cannot replace definitive antileukaemic treatment.

IMF-039-02-0012-en	Why are corticosteroids avoided before lymph-node biopsy for suspected lymphoma, and when is that rule overridden?	They rapidly shrink lymphoid tissue and obscure the architecture the diagnosis depends on, unless an airway, cord, brain, or other organ threat demands treatment.

IMF-039-02-0013-en	Through which mechanisms do plasma-cell clones injure the body by mass and by protein?	Marrow replacement causes anaemia, osteoclast activation causes lytic bone disease and hypercalcaemia, filtered free light chains damage tubules, and low normal immunoglobulin increases infection.

IMF-039-02-0014-en	In tumour lysis syndrome, why is asymptomatic hypocalcaemia not corrected casually?	Phosphate complexes calcium, so added calcium can increase calcium phosphate deposition in the kidney; symptoms and the chemistry as a whole guide correction.

IMF-040-01-0001-en	Why is malignancy not defined simply by rapid growth?	Cancer is clonal evolution within tissue, and tumours vary in differentiation, invasion, metastasis, treatment sensitivity and host interaction, so growth rate alone does not capture malignant behaviour.

IMF-040-01-0002-en	What distinguishes how proto-oncogenes and tumour-suppressor genes contribute to cancer?	Proto-oncogenes promote growth or survival and become drivers through activating mutation, amplification or fusion; tumour suppressors restrain proliferation, and both copies often need functional loss at the cellular level.

IMF-040-01-0003-en	Why can a mutation found in a tumour not be assumed to drive it?	Passenger changes accumulate without providing major advantage, and even a driver essential in one clone can be bypassed by another clone.

IMF-040-01-0004-en	How does treatment itself shape the tumour population that later relapses?	Tumours contain subclones with different vulnerabilities; treatment removes sensitive cells and selects resistant populations, while new mutations and non-genetic plasticity continue evolution.

IMF-040-01-0005-en	Tumour-only sequencing suggests a possible inherited variant. Why does this matter beyond the tumour, and what follows?	A germline defect exists throughout the body and affects relatives, surveillance and therapy, so the finding requires counselling and confirmatory testing.

IMF-040-01-0006-en	Why is no single hallmark of malignancy sufficient to make a cell cancerous?	No hallmark is unique to cancer; malignancy emerges from the combination and persistence of the traits, which genomic instability and tumour-promoting inflammation enable.

IMF-040-01-0007-en	Through which mechanisms do oncogenic infections promote cancer, and how does this make some cancers preventable?	They act through microbial proteins, inflammation, immune suppression or regeneration, so vaccination and antimicrobial treatment can remove the cause and prevent cancer.

IMF-040-01-0008-en	Why should cancer prevention messages avoid blaming the individual?	Risk is probabilistic: exposure does not guarantee cancer, and messages should account for social, commercial and environmental determinants rather than personal fault.

IMF-040-01-0009-en	How does hypoxia in a tumour promote progression and treatment failure?	Hypoxia stabilises transcriptional programmes that support angiogenesis, glycolysis, invasion and treatment resistance.

IMF-040-01-0010-en	Why do tumour vessels supply resources yet leave perfusion uneven?	New tumour vessels are structurally abnormal, leaky, heterogeneous and poorly organised, so they deliver resources while perfusing the tumour unevenly.

IMF-040-01-0011-en	How can a tumour continue to grow despite anti-angiogenic therapy?	It can recruit alternative vascular pathways or invade along existing vessels, bypassing the inhibited angiogenesis.

IMF-040-01-0012-en	Why is metastasis not a single irreversible switch such as epithelial-mesenchymal change?	Epithelial-mesenchymal programmes increase movement and plasticity, but cells must still enter vessels, survive shear and immunity, arrest, exit and adapt to a foreign niche.

IMF-040-01-0013-en	Why can distant metastases appear years after the primary tumour is treated?	Most disseminated cells fail, but some remain dormant for years before outgrowth once blood flow, adhesion, chemokines and niche allow.

IMF-040-01-0014-en	What does lymph-node involvement imply about how distant metastases arose?	It reflects spread and prognosis, but it does not mean every distant metastasis passed sequentially through each node.

IMF-040-01-0015-en	Why does portal drainage favour liver metastasis while systemic venous drainage favours lung?	Circulating tumour cells arrest in the distant capillaries their drainage reaches, and metastasis depends partly on blood flow, alongside adhesion, chemokines and niche compatibility.

IMF-040-01-0016-en	Why can checkpoint inhibitors cause inflammation in almost any organ, and what does management require?	They release inhibitory brakes on T cells, and the activated immunity can inflame skin, bowel, liver, lung, endocrine organs, heart, kidney or nerves; early recognition and graded immunosuppression are crucial.

IMF-040-01-0020-en	Why can a tumour marker rarely diagnose cancer on its own?	Benign disease can raise tumour markers and some cancers do not secrete them, so the marker gives both false positives and false negatives.

IMF-040-02-0001-en	Why can a repeat biopsy or circulating tumour analysis change treatment?	A biopsy samples one region at one time, and because selection keeps reshaping the tumour, the dominant clone in a metastasis or relapse may differ from the primary.

IMF-040-02-0005-en	Why is adjuvant systemic treatment given after surgery has removed all visible disease?	Surgery cannot prove that microscopic disseminated cells are absent, and dormant cells can reactivate years later, so treatment is given when recurrence risk justifies toxicity.

IMF-040-02-0008-en	Why should a patient with suspected immune toxicity and physiological instability be treated before infection is excluded?	Myocarditis, severe pneumonitis, neuromuscular-junction disorders and adrenal crisis are uncommon but rapidly fatal, and mild symptoms do not establish that an organ is safe.

IMF-040-02-0009-en	Why is imaging used to target a viable advancing margin rather than the most accessible site for biopsy?	The most accessible site is not necessarily the most representative, and a necrotic centre may not yield viable tumour for diagnosis.

IMF-040-02-0014-en	In a stable patient with superior vena-cava obstruction, why should radiation not be rushed before tissue diagnosis?	Radiation before biopsy can destroy the pathology needed for diagnosis; only airway compromise, cerebral oedema or circulatory crisis justify treating before diagnosis.

IMF-041-01-0001-en	Why can an autoantibody result not substitute for clinical reasoning in suspected autoimmune disease?	Diagnosis rests on phenotype and objective organ involvement, and similar syndromes arise from infection, malignancy, drugs or inherited immune dysregulation; autoantibodies only modify probability.

IMF-041-01-0003-en	How do central and peripheral tolerance differ in the way they control self-reactive lymphocytes?	Central tolerance deletes or edits strongly self-reactive lymphocytes during development; peripheral tolerance restrains escaped cells through anergy, regulatory T cells, inhibitory receptors, antigen sequestration, and absent costimulation.

IMF-041-01-0004-en	Why do most people exposed to triggers such as infection, ultraviolet radiation or smoking not develop autoimmune disease?	Autoimmunity reflects an interaction among inherited risk, immune history, sex and age, environment, and chance, so a trigger alone is not sufficient.

IMF-041-01-0006-en	Why should a clinician not assume a single damage mechanism in an autoimmune patient?	Injury can come from receptor-blocking or stimulating antibodies, immune complexes, complement, cytotoxic T cells, macrophages, granulomas, thrombosis or fibrosis, and several can operate at once.

IMF-041-01-0007-en	Why is a positive antinuclear antibody weak evidence on its own, and when should it be tested?	It occurs in healthy people, infection, drugs, cancer and relatives as well as connective-tissue disease, so it is tested only when pretest probability justifies it; titre and pattern guide follow-up but do not diagnose.

IMF-041-01-0009-en	Why are inflammatory markers a poor guide to serious autoimmune organ disease, and what gives stronger evidence of damage?	They are nonspecific and can be normal during serious organ disease; complement consumption, blood counts, urine sediment, protein excretion, kidney function, imaging and biopsy often show damage better.

IMF-041-01-0010-en	Why does lupus require regular blood pressure, creatinine, urine sediment and protein measurement even without symptoms?	Lupus kidney involvement ranges from mild urinary abnormalities to proliferative or membranous glomerular disease and can be silent; regular measurement detects it, and biopsy classifies it when treatment depends on it.

IMF-041-02-0009-en	In scleroderma renal crisis, why is angiotensin-converting-enzyme inhibition continued despite an early creatinine rise?	When the diagnosis fits, renin-driven vascular injury otherwise progresses, so inhibition is started promptly and continued.

IMF-041-02-0010-en	Why is inflammatory myopathy followed by serial power measurement rather than creatine kinase alone?	The disease is recognised through loss of power, so weakness of neck flexion, shoulder and hip movement, finger flexion, swallowing, cough and respiration is measured serially.

IMF-041-02-0011-en	Why can imaging and temporal-artery biopsy for giant-cell arteritis be arranged without delaying glucocorticoids?	Ultrasound, arterial imaging and temporal-artery biopsy retain diagnostic value for a period after treatment, so treatment of threatened visual ischaemia need not wait.

IMF-041-02-0012-en	In suspected alveolar haemorrhage, why are cultures and imaging obtained before and after immunosuppression begins?	Lung opacity and anaemia arise from both infection and haemorrhage, so specimens and imaging around the start of treatment are needed to tell them apart.

IMF-041-02-0014-en	During treatment, why must clinicians neither reflexively escalate immunosuppression nor wait for complete certainty?	Escalating without new specimens and anatomy can worsen the true cause, yet waiting during visual loss, alveolar haemorrhage, renal crisis or mesenteric ischaemia causes irreversible damage.

IMF-042-01-0001-en	Why can illness progress more rapidly in children than in adults?	Airway diameter, fluid, glucose and cardiorespiratory reserve are all limited, so a child has little margin before decompensating.

IMF-042-01-0002-en	How do the resistance changes at birth lead to functional closure of the fetal shunts?	Aeration lowers pulmonary resistance and cord clamping raises systemic resistance; increased pulmonary venous return then raises left-atrial pressure, and the fetal shunts begin to close functionally.

IMF-042-01-0003-en	Why do some congenital cardiac lesions deteriorate after birth, and what is the trade-off of prostaglandin infusion?	They depend on ductal flow and worsen as the duct closes; prostaglandin preserves patency while anatomy is defined, but it may cause apnoea and so requires specialist support.

IMF-042-01-0004-en	In newborn resuscitation, what shows that ventilation is working, and where do compressions and medicines rank?	A heart-rate response indicates successful ventilation, and in most neonatal collapse compressions and medicines are secondary to lung inflation.

IMF-042-01-0005-en	Why do neonates lose heat quickly, and why does cold stress worsen hypoglycaemia and acidosis?	A high surface-area-to-mass ratio, thin skin, limited insulation and poor behavioural control speed heat loss, and brown-fat thermogenesis consumes oxygen and glucose.

IMF-042-01-0006-en	Why is the newborn at risk of hypoglycaemia, and why can it be missed?	Glucose supply must shift from placental transfer to feeding and endogenous production, and the resulting hypoglycaemia may be silent rather than causing jitteriness, apnoea, lethargy or seizure.

IMF-042-01-0008-en	Which features distinguish pathological from physiological neonatal jaundice?	Jaundice in the first day, rapid rise, prolonged elevation, pallor, illness, dark urine, pale stool or high concentration suggest pathology, and conjugated jaundice is never physiological.

IMF-042-01-0009-en	Why is a bilirubin concentration interpreted by postnatal age and risk rather than as a single cut-off?	Unconjugated bilirubin can enter brain and cause encephalopathy or kernicterus, and prematurity, haemolysis, acidosis, sepsis or low albumin binding raise that danger.

IMF-042-01-0010-en	What is the danger of excessive early weight loss in a feeding newborn, and how should feeding support be approached?	It can cause hypernatraemic dehydration; support should identify tongue, palate, cardiac, respiratory, neurological and other barriers without blame.

IMF-042-01-0011-en	Why is serial growth velocity more informative than a single centile?	A single point cannot show trajectory, whereas serial velocity and the relation among measurements reveal how growth is changing; age is corrected for prematurity when appropriate.

IMF-042-01-0012-en	Why is developmental regression more concerning than isolated mild delay, and what can mimic global delay?	Regression may signal neurodegenerative, metabolic, epileptic, structural or psychosocial disease, and hearing or vision impairment can mimic global delay.

IMF-042-01-0013-en	Why does a small reduction in airway radius matter so much in infants, and why is cyanosis an unreliable sign?	Airways are small, so slight narrowing greatly increases resistance; cyanosis is a late sign and can be hard to identify across skin pigmentation.

IMF-042-01-0015-en	Why is hypotension a late sign of shock in children, and what precedes it?	Children preserve pressure by vasoconstriction until late shock, so tachycardia, prolonged capillary refill, cool peripheries, altered interaction, reduced urine and weak pulses come first.

IMF-042-01-0016-en	Why can a child with obesity still have a clinically important micronutrient deficiency?	Obesity can coexist with deficiency, and deficiency can impair development before physical signs appear, so non-stigmatising family and environmental assessment is needed.

IMF-042-02-0011-en	After a fluid aliquot, what findings should prompt reconsideration of cardiac and vasoactive support rather than more volume?	Poor improvement with increasing liver enlargement and crackles suggests fluid is not helping and may be harmful.

IMF-042-02-0012-en	How does oral rehydration work, and why is abnormal sodium corrected in a controlled way?	It uses coupled sodium-glucose absorption; sodium disorders are corrected in a controlled way because rapid osmotic shifts injure brain.

IMF-042-02-0013-en	Why may a dose appropriate in one neonatal week become wrong later?	Infants have higher total-body water and lower protein binding, and hepatic enzymes and glomerular filtration mature at different rates, so drug handling keeps changing.

IMF-042-02-0014-en	Why should a caregiver's report that the child is not as usual outweigh a single normal set of observations?	It is longitudinal data about deviation from that child's own baseline, which a single normal set of numbers at one moment cannot cancel.

IMF-043-01-0001-en	Normal ageing narrows homeostatic range. Why, then, can chronological age not define an older person's physiological reserve?	How much reserve is actually lost is determined by disease, inactivity, nutrition, environment, and social conditions, so ageing is heterogeneous.

IMF-043-01-0002-en	Why does cardiovascular ageing reduce exercise reserve and increase orthostatic hypotension even when resting function seems adequate?	Adrenergic responsiveness, maximum heart rate, and baroreflex sensitivity decline, so the limitation is exposed only when stress demands compensation.

IMF-043-01-0003-en	How do age-related lung changes increase the risk of aspiration and infection?	Lungs lose recoil, chest-wall compliance, clearance, cough strength, and gas-exchange reserve, so material is cleared less effectively and infection is tolerated poorly.

IMF-043-01-0005-en	How do age-related changes in body composition and liver function alter the handling of water-soluble and lipid-soluble drugs?	Less body water and lean mass with more fat lets water-soluble drugs concentrate and lipid-soluble drugs persist; phase-one metabolism may decline while conjugation is better preserved.

IMF-043-01-0006-en	Processing speed and muscle power change with age. Which two conclusions must not be drawn from this?	That dementia is part of normal ageing, and that resistance training is no longer effective; both are false, and reserve varies greatly.

IMF-043-01-0007-en	What distinguishes the phenotype and accumulated-deficit concepts of frailty, and what do both predict?	The phenotype uses weakness, slow walking, low activity, exhaustion, and weight loss; deficits accumulate across disease, function, cognition, and social domains. Both predict falls, delirium, disability, institutionalisation, toxicity, and death.

IMF-043-01-0008-en	Why must a frailty score not be used to deny treatment automatically?	Frailty is dynamic and can improve with nutrition, rehabilitation, medication review, support, and treatment of reversible disease, so the question is whether benefit, burden, and recovery path fit this individual.

IMF-043-01-0009-en	In sarcopenia, why do strength and performance matter more than muscle mass, and what is central to treatment?	Sarcopenia is loss of strength with reduced quantity or quality, so function matters more than mass alone; progressive resistance exercise, adequate nutrition, and treating causes are central.

IMF-043-01-0010-en	How do basic and instrumental activities of daily living differ, and why is decline from baseline clinically important?	Basic activities cover self-care such as feeding, dressing, toileting, bathing, transfers; instrumental ones cover shopping, cooking, medicines, finances. Decline from baseline may be the most sensitive sign of illness.

IMF-043-01-0011-en	Why should caregivers be included in geriatric assessment, yet the patient also be spoken to privately?	Caregiver reports can clarify change, while speaking directly and privately to the patient protects autonomy and allows abuse or coercion to be detected.

IMF-043-01-0012-en	How may infection and myocardial infarction present atypically in older adults?	Infection may occur without fever or leukocytosis, and myocardial infarction may cause breathlessness, weakness, or confusion rather than pain; illness often appears as delirium, falls, or functional decline.

IMF-043-01-0013-en	Why should several modest insults not be dismissed when an older person becomes acutely confused?	Infection, constipation, sleep loss, unfamiliar surroundings, sedatives, and sensory impairment interact, so together they can cause severe delirium; new symptoms must not be attributed to age.

IMF-043-01-0014-en	What distinguishes delirium from dementia, and which form of delirium is most often missed?	Delirium is acute, fluctuating inattention caused by physiological disturbance, whereas dementia is chronic acquired decline interfering with independence; quiet hypoactive delirium is frequently missed.

IMF-043-01-0015-en	Why are antipsychotics not a treatment for delirium itself, and when may they be used?	They do not cure delirium, which requires treating the cause; they are reserved for selected severe distress or danger after non-drug measures, given cardiac, motor, stroke, and mortality risk.

IMF-043-01-0016-en	Why must cognitive test results in an older person be interpreted with caution?	Scores are influenced by education, culture, language, hearing, vision, pain, and fatigue, and depression can mimic or worsen cognitive impairment.

IMF-043-01-0017-en	Why does effective falls prevention combine several interventions rather than one?	Falls usually have multiple causes, so prevention combines strength and balance exercise, medication reduction, vision and footwear care, home modification, continence management, and treating cardiovascular or neurological causes.

IMF-043-01-0018-en	Why is a fall described as a syndrome rather than a diagnosis, and why does fear-driven inactivity matter?	A fall reflects underlying causes that must be investigated, including why the person could not get up; fear-driven inactivity worsens the risk of further falls.

IMF-043-01-0019-en	Why does appropriateness matter more than drug count in polypharmacy, and how does a prescribing cascade arise?	Following several disease guidelines can accumulate drugs whose combined burden exceeds benefit; a cascade occurs when an adverse effect is mistaken for a new disease and treated with another drug.

IMF-043-01-0020-en	Which drug classes carry increased pharmacodynamic sensitivity in older adults, and what practical factors also affect safety?	Sedatives, anticholinergics, opioids, anticoagulants, glucose-lowering and pressure-lowering drugs; interactions, duplicates, complex schedules, swallowing, cost, cognition, and dexterity also affect safety.

IMF-043-01-0021-en	Which medicines are prioritised for deprescribing, and why must some be tapered?	Drugs without indication, duplicates, those causing harm, preventive drugs whose time to benefit exceeds prognosis, and those inconsistent with goals; some need tapering to avoid withdrawal or rebound.

IMF-043-01-0022-en	Why is serum albumin not a standalone measure of nutrition, and what is assessed instead?	Albumin is altered by inflammation and hydration; weight trajectory, intake, muscle, function, oral health, and feeding support are assessed instead.

IMF-043-01-0023-en	Why do indwelling catheters rarely solve chronic incontinence?	They create infection and trauma; chronic incontinence arises from urge, stress, overflow, functional, or mixed mechanisms that bladder diaries, residual measurement, and examination should identify.

IMF-043-01-0024-en	What must be done before concluding that an older person lacks capacity, and why is an unwise decision not enough?	Support communication, treat delirium, optimise hearing and vision, use interpreters, and simplify information; capacity depends on understanding, retaining, weighing, and communicating, not on the choice being wise.

IMF-043-02-0001-en	Why are baseline function and speed of change treated as diagnostic vital signs in older people?	Narrowed reserve lets acute illness cross several thresholds at once, so it presents as a fall, confusion, immobility, poor intake, or new dependence rather than a textbook organ syndrome.

IMF-043-02-0002-en	How can frailty and comorbidity dissociate in an individual patient?	Frailty is reduced multidimensional reserve with impaired recovery after stress, so a person can have several stable diseases without frailty, or substantial frailty with a short diagnosis list.

IMF-043-02-0003-en	How can a minor procedure or urinary infection lead to institutional dependence, and how is this cascade prevented?	It can trigger delirium, immobility, deconditioning, incontinence, and pressure injury; prevention uses early mobilisation, own clothes, meals out of bed, glasses and hearing aids, sleep protection, and rehabilitation from day one.

IMF-043-02-0004-en	Why is the single word "independent" inadequate for establishing baseline, and what determines discharge destination?	Baseline needs specific questions about transfers, walking, stairs, bathing, cooking, medicines, and finances; destination follows recovery trajectory, housing, support, and goals, not current function alone.

IMF-043-02-0006-en	How does the heart-rate response on standing distinguish neurogenic orthostatic hypotension from volume depletion?	In neurogenic hypotension the heart-rate rise is disproportionately small for the pressure fall; in volume depletion it is greater than usual, though beta blockers and a pacemaker alter interpretation.

IMF-043-02-0007-en	Why may drug dosing in frail older people require more than an estimated filtration equation?	Low muscle mass makes little creatinine and equations fail in frailty, amputation, oedema, or changing function, so trends, cystatin estimates, measured clearance, and clinical toxicity may be needed.

IMF-043-02-0008-en	Why is pharmacodynamic vulnerability often more important than altered kinetics in older adults?	Drugs such as benzodiazepines, opioids, anticholinergics, insulin, and anticoagulants can cause disproportionate delirium, falls, retention, hypoglycaemia, bleeding, or syncope beyond what kinetics predict.

IMF-043-02-0009-en	Why does medication reconciliation ask what is actually taken rather than reading the list?	Non-prescription analgesics, antihistamines, sleep products, supplements, patches, inhalers, eye drops, borrowed medicines, and intentionally skipped doses are otherwise missed.

IMF-043-02-0010-en	Why is deprescribing made in stages, and how is its success measured?	Changing many medicines at once obscures the cause of benefit or harm; success is improvement in alertness, mobility, continence, symptoms, and treatment burden, not just fewer medicines.

IMF-043-02-0011-en	Why does inability to rise after a fall matter, and why does walking not exclude fracture?	Prolonged time on the floor causes pressure injury, hypothermia, dehydration, rhabdomyolysis, kidney injury, and fear; pain may be muted, so occult hip, pelvic, or vertebral fracture can be missed.

IMF-043-02-0012-en	Why should an acute decline in a person with dementia, or a quietly sleeping patient, prompt assessment for delirium?	Dementia strongly predisposes to delirium but does not explain an acute decline, and a quiet sleeping patient may have hypoactive delirium rather than benign fatigue.

IMF-043-02-0013-en	What does it mean that capacity is not all or nothing, and on what basis does a substitute decision-maker act?	A person may manage simple everyday decisions yet find a complex high-risk operation difficult to judge; a substitute acts on the person's known values and best interests, not their own preference.

IMF-043-02-0014-en	How does goal-concordant geriatric care differ from simply offering less treatment because a person is old?	It offers proportionate care informed by reserve, reversibility, burden, and what makes the outcome worthwhile, discussing best, worst, and most likely functional outcomes.

IMF-044-01-0001-en	In acute care, why is a single normal observation not enough to stop worrying about a patient?	Acute care prioritises reversible threats before diagnosis, and trajectory and treatment response carry more weight than any one normal observation.

IMF-044-01-0002-en	During the trauma primary survey, what do you do when a life threat is found, and when is the patient reassessed?	Each life threat is treated as soon as it is found rather than after completing the survey, and the patient is reassessed after every intervention and whenever condition changes.

IMF-044-01-0003-en	How is a tourniquet applied for severe limb bleeding, and what practice must be avoided?	It is placed proximal to the bleeding, tightened until bleeding stops, and the time documented; it must not be periodically loosened outside a controlled plan.

IMF-044-01-0004-en	How is the airway opened when cervical injury is possible, and what guides the choice of adjunct?	Jaw thrust is used, followed by suction, removal of visible obstruction and oxygen; adjuncts are chosen according to the patient's reflexes and anatomy.

IMF-044-01-0006-en	Rapid-sequence intubation can precipitate hypotension and arrest in which states, and how is this risk reduced?	In severe hypovolaemia, right-heart obstruction, or metabolic acidosis; physiology is resuscitated first, drugs chosen carefully, a failed-airway plan prepared, and placement confirmed with continuous waveform carbon dioxide.

IMF-044-01-0007-en	Why should rigid spinal immobilisation not be prolonged or allowed to delay airway or haemorrhage control?	Prolonged rigid immobilisation causes pressure injury, aspiration risk, pain and raised intracranial pressure, so the spine is cleared through validated clinical or radiological pathways.

IMF-044-01-0008-en	Why is suspected tension pneumothorax with shock treated before imaging?	When shock or severe respiratory compromise accompanies suspected raised pleural pressure, the threat is immediately life-threatening, so treatment must not wait for imaging.

IMF-044-01-0009-en	How do flail segments and pulmonary contusion harm gas exchange, and what forms the core of management?	They cause pain, impaired ventilation and delayed hypoxaemia, so analgesia, physiotherapy and selective ventilatory support are central.

IMF-044-01-0010-en	Why can blood pressure be falsely reassuring in trauma shock, and which factors alter the signs?	Young patients can maintain pressure until late, so earlier signs such as tachycardia, cool skin, narrow pulse pressure and reduced urine matter; beta blockade, pacing, pregnancy and age alter them.

IMF-044-01-0011-en	Why is excess crystalloid harmful in major haemorrhage?	It dilutes clotting factors, worsens oedema, and causes hypothermia and acidosis, so warmed blood components are used to restore perfusion.

IMF-044-01-0012-en	Why is permissive hypotension in damage-control resuscitation inappropriate in severe traumatic brain injury?	Cerebral perfusion requires a higher pressure in severe brain injury, so accepting low pressure until haemostasis would risk the brain.

IMF-044-01-0013-en	What makes the lethal triad self-reinforcing, and how is the cycle broken?	Hypothermia, acidosis and coagulopathy each worsen the others, aggravated by exposure, cold fluid, shock and long procedures; warm everything, control bleeding, restore perfusion and shorten definitive procedures when physiology is exhausted.

IMF-044-01-0014-en	Why should the components of a simple coma scale be recorded, not just the total score?	Eye, verbal and motor responses are affected by intoxication, sedation, language, hearing, paralysis and intubation, so a total alone can mislead.

IMF-044-01-0015-en	Which empirical treatments are given in altered consciousness, and what must they not delay?	Glucose for documented or strongly suspected hypoglycaemia, naloxone for likely opioid toxicity with respiratory depression, and anticonvulsant treatment for ongoing seizure; none should delay ventilation or imaging.

IMF-044-01-0016-en	Which signs suggest brain herniation, and what response do they demand?	An expanding pupil, declining consciousness or new posturing; they require urgent hyperosmolar therapy, controlled rescue ventilation when imminent, imaging, and neurosurgical intervention.

IMF-044-01-0017-en	Why is the head-to-toe secondary survey repeated rather than done once?	Pain, distraction, shock and evolution of injury conceal findings, so a single examination can miss injuries that later become apparent.

IMF-044-01-0018-en	What are the limits of focused ultrasound and computed tomography in trauma?	Focused ultrasound rapidly detects selected pericardial, pleural and intraperitoneal fluid but cannot exclude all injury; tomography suits stable patients and must not delay surgery for obvious ongoing haemorrhage.

IMF-044-01-0019-en	What causes neurogenic shock, and what distinguishes its presentation?	Loss of sympathetic tone after spinal-cord injury causes hypotension, often with relative bradycardia, and the diagnosis is made only after haemorrhage is excluded.

IMF-044-01-0020-en	Why must neurovascular status be documented before and after interventions for limb injury?	Limb tissue is threatened by arterial disruption, compartment syndrome, open fracture or crush, so change after an intervention can only be recognised against a documented baseline.

IMF-044-01-0021-en	In cardiac arrest, why must airway interventions not degrade compressions, and what does waveform carbon dioxide add?	Minimising interruptions to high-quality compressions is central to arrest care; waveform carbon dioxide confirms tube placement and can indicate compression quality or return of circulation.

IMF-044-01-0022-en	Why is definitive neurological prognosis delayed after return of spontaneous circulation?	Confounders must be addressed and an appropriate time must pass before prognosis is reliable, so it is not declared early.

IMF-044-01-0023-en	Why is preoperative testing limited to tests that can change management?	Preoperative assessment is risk modification, not clearance; a normal test does not neutralise poor functional status, and routine indiscriminate testing creates false positives.

IMF-044-01-0024-en	Why are sodium-glucose cotransporter inhibitors withheld before surgery, and what must diabetes plans prevent?	They can cause euglycaemic ketoacidosis around fasting and surgery, and diabetes plans must prevent both hypoglycaemia and ketosis.

IMF-044-02-0001-en	Why can a normal initial blood pressure or scan not end trauma assessment?	Compensation hides injury and bleeding evolves, so resuscitation proceeds as repeated hypothesis testing guided by mechanism and response to treatment.

IMF-044-02-0002-en	Why must a pelvic binder be placed at the greater trochanters rather than over the iliac crests?	At the trochanters it reduces pelvic volume and motion, limiting bleeding; placed over the iliac crests it is ineffective.

IMF-044-02-0003-en	By what mechanism can rapid-sequence induction precipitate arrest in hypovolaemia, tamponade or tension pneumothorax?	Induction removes sympathetic tone and positive-pressure ventilation reduces venous return, so patients depending on both can lose their circulation.

IMF-044-02-0004-en	Why can needle decompression of tension pneumothorax fail, and what provides more definitive relief?	Inadequate catheter length, kinking, clot or wrong position can defeat it; finger thoracostomy or tube drainage is more definitive according to setting and expertise.

IMF-044-02-0009-en	Why is an early poor motor response alone insufficient grounds to withdraw treatment after cardiac arrest?	Sedatives, paralysis, hypothermia, shock and metabolic failure confound neurological assessment, so prognosis is multimodal and delayed until timing and confounders permit.

IMF-044-02-0010-en	Why must the limiting symptom be identified when assessing functional capacity before surgery?	Functional capacity integrates cardiac, respiratory, musculoskeletal, neurological and motivational limits, so inability to climb stairs may reflect knee pain rather than myocardial reserve.

IMF-044-02-0011-en	Why is bridging not applied universally when anticoagulation is stopped before surgery?	Stopping anticoagulation reduces bleeding but may expose mechanical valves, recent thrombosis or high-risk atrial fibrillation, and bridging itself causes bleeding, so the hazards are balanced.

IMF-044-02-0013-en	When reassessing limb compartments, why is a palpable pulse not reassuring?	Compartment compromise is tracked through pain, pain on passive stretch, tension, sensation and movement, and the presence of a pulse does not exclude compromise.

IMF-044-02-0014-en	During massive transfusion, why does a rise in blood pressure alone not prove haemostasis?	Pressure can rise while bleeding continues, so transfusion requirement, drain output, abdomen and pelvis, peripheral perfusion and the acid-base trajectory are all examined.

IMF-045-01-0001-en	Why must psychiatric assessment include physical and neurological assessment rather than rely on the story and mental state alone?	Symptoms can arise not only from primary mental illness but from drugs, withdrawal, infection, neurological disease, endocrine disturbance, trauma, sleep loss, or severe stress.

IMF-045-01-0002-en	When does collateral information become essential, and how can it be obtained while respecting confidentiality?	When cognition, psychosis, intoxication, communication, or risk limits the history; consent is sought where possible, and clinicians may receive information without disclosing confidential details.

IMF-045-01-0003-en	What distinguishes mood from affect in the mental state examination?	Mood is the sustained subjective emotion the person reports, while affect is the observed range, intensity, stability, reactivity, and congruence, and the two can differ.

IMF-045-01-0004-en	What makes a belief a delusion rather than an unusual belief, and how should the clinician explore it?	A delusion is a fixed false belief held outside the person's cultural context, and its certainty is explored respectfully.

IMF-045-01-0005-en	Which cognitive findings point towards delirium in the mental state examination?	Inattention and fluctuation suggest delirium, which is why arousal and attention are assessed alongside orientation, memory, language, visuospatial and executive function.

IMF-045-01-0006-en	How do insight and judgement differ, and why does neither mean agreeing with the clinician?	Insight is awareness and interpretation of one's condition, while judgement is demonstrated decision-making; both are judged on the person's awareness and reasoning, so neither means agreement with the clinician.

IMF-045-01-0008-en	Why are tests for medical causes targeted to features such as sudden onset or focal neurology rather than run as broad screening?	Features like sudden or late onset, fluctuating attention, focal signs, fever, or medication change direct which causes to exclude, whereas routine broad screening can produce incidental findings.

IMF-045-01-0009-en	Why is decision-making capacity assessed for a specific decision at a specific time, and which abilities are tested?	Capacity can fluctuate and differ between simple and complex decisions; the person must understand, retain, use or weigh the information, and communicate a choice.	Integrated Medical Foundations; chapter 45, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 39fea89ec338123253bc6971649649fef91980bb87ad913cad3367e8de2f964e; editorial review pending	imf lang::en chapter::045 module::045-01 review::pending
IMF-045-01-0010-en	Why does neither an apparently unwise choice nor the presence of a delusion prove incapacity?	Capacity concerns the decision-making process; a delusion matters only if it prevents understanding or weighing the specific decision.

IMF-045-01-0011-en	If capacity is absent, what guides the decision and what must be documented?	Emergency necessity, advance directives, substitute decision-makers, best-interest standards, and local law, using the least restrictive alternative and documenting evidence, support offered, reasoning, and review plan.

IMF-045-01-0012-en	Why should clinicians ask directly and calmly about suicidal thoughts rather than avoid the topic?	Asking does not implant the idea, and direct questions reveal plans, intent, preparation, access to means, what stopped action, and whether risk is changing.

IMF-045-01-0013-en	Why can suicide risk not be reduced to a score or low-medium-high label, and what is formulated instead?	A label says nothing about why or how risk may change, so clinicians formulate dynamic and enduring factors, foreseeable scenarios, protective resources, access to lethal means, and ability to seek help.

IMF-045-01-0014-en	What distinguishes a safety plan from a no-suicide contract?	A safety plan is collaborative and specific, identifying warning signs, internal coping, social distraction, trusted contacts, professional services, and means restriction, rather than being a promise.

IMF-045-01-0015-en	Why is psychiatric diagnosis a weaker guide to violence risk than other factors?	Most people with mental illness are not violent; substance use, past behaviour, situational factors, and access often predict violence more strongly than diagnosis.

IMF-045-01-0017-en	Grief and adversity can cause intense distress. How does this bear on the diagnosis of major depression?	Distress can occur without a disorder, yet the presence of an understandable context does not exclude major depression.

IMF-045-01-0018-en	Why are cognitive behavioural and exposure therapies preferred to long-term benzodiazepines in anxiety disorders?	Cognitive behavioural and exposure therapies reduce avoidance, whereas long-term benzodiazepines cause tolerance, dependence, falls, and cognitive impairment.

IMF-045-01-0021-en	Why can schizophrenia-spectrum illness not be diagnosed at a first psychotic episode on symptoms alone?	First-episode diagnosis requires longitudinal exclusion of mood, substance, neurological, autoimmune, endocrine, infectious, and developmental causes.

IMF-045-01-0022-en	Why must catatonia be recognised urgently, and why can antipsychotics be a problem?	Dehydration, thrombosis, pressure injury, malnutrition, and malignant deterioration occur; benzodiazepine challenge and ECT are key treatments, while antipsychotics can worsen some cases.

IMF-045-01-0023-en	Why does a positive toxicology result not prove current impairment?	Toxicology has detection windows, so a positive result shows exposure within that window rather than present impairment.

IMF-045-01-0024-en	Why should a personality disorder diagnosis not be made from a single crisis presentation?	Diagnosis requires longitudinal context and should not become pejorative shorthand; in crisis, clinicians validate distress, keep consistent boundaries, and avoid splitting care teams.

IMF-045-02-0001-en	Why is "hearing a voice" described in detail before a syndrome is assigned?	It may be a hallucination, intrusive thought, dissociation, misheard sound, sleep-transition phenomenon, trauma memory, or delirium; precise phenomenology improves diagnosis and rapport.

IMF-045-02-0002-en	How do circumstantial and tangential speech differ, and how does flight of ideas differ from loosening of associations?	Circumstantial speech reaches the point through excessive detail while tangential speech never returns; flight of ideas has rapid understandable links, whereas loosening makes links hard to follow.

IMF-045-02-0004-en	Why are arousal and attention tested before memory when screening cognition?	Tasks such as months backward, digit span, or a multistep command reveal inattention that orientation questions miss, and impaired attention with acute change and fluctuation suggests delirium.

IMF-045-02-0005-en	Why can a person have capacity to accept food but not to manage a complex high-risk discharge?	Capacity is a functional assessment of a defined decision, not a global label, so it depends on the information that decision requires and can return once reversible barriers are treated.

IMF-045-02-0007-en	In a capacity assessment record, why is a diagnosis or cognitive test score not a conclusion, and how is fluctuating capacity handled?	The record must show the person's understanding and weighing of the specific decision; when capacity fluctuates, important decisions move to the best time of day and non-urgent ones wait.

Patterns and trends, not a single reading, guide recognition of physiological threat; a normal pressure does not exclude shock.

IMF-046-01-0002-en	Why should the patient's pre-intervention state be recorded before treatment starts?	Because the response to treatment helps distinguish between mechanisms, and that comparison depends on knowing the state before intervention.

IMF-046-01-0003-en	What does a problem representation compress into one sentence, and when should negative findings be included in it?	It compresses context, tempo, syndrome, severity and discriminating findings; negatives are included only when they are reliable and discriminating.

IMF-046-01-0004-en	How is an active problem list ranked, and how are duplicate entries handled?	Problems are ranked by physiological threat, reversibility, time sensitivity and patient priority; duplicates are merged while preserving causal relationships.

IMF-046-01-0005-en	What should a focused differential for an unresolved syndrome include, and why is a long unranked list not safer?	Built from anatomy, mechanism and tempo, it includes likely causes, dangerous alternatives and diagnoses plausible from this patient's exposures or comorbidity; a short reasoned list is at least as safe.

IMF-046-01-0006-en	When can time spent on diagnosis be therapeutic, and when is immediate empirical action required instead?	When the patient is stable, diagnostic time can itself be therapeutic; when delay risks irreversible harm, immediate empirical action is needed.

IMF-046-01-0007-en	What should be predicted before ordering a test, and what follows if no result would change the plan?	Predict how each possible result would change action; if none would, the test should be reconsidered.

IMF-046-01-0008-en	Why should a treatment plan specify drug, indication, dose, route, interval, review date, monitoring and stop conditions?	So that another clinician can continue it safely; treatment is written around goals and mechanisms, not as an isolated order.

IMF-046-01-0009-en	What does a therapeutic trial require, and what may a lack of response reflect?	A defined target, time frame and alternative explanation; lack of response may reflect wrong diagnosis, inadequate delivery, advanced irreversible disease or insufficient time.

IMF-046-01-0010-en	Why may preventing hypoglycaemia matter more than intensive glucose control during an acute admission?	Benefits are balanced over different time horizons: intensive control may not help the acute admission, whereas preventing hypoglycaemia does.

IMF-046-01-0011-en	What does medication reconciliation compare, and how is each difference classified?	It compares medicines actually used before admission with current orders and the intended discharge regimen, classifying each difference as intentional or unintentional.

IMF-046-01-0012-en	Why must a held medicine be documented with its reason and restart criteria?	A discharge list without explanation transfers ambiguity to the patient and the next clinician.

IMF-046-01-0013-en	During daily ward review, how should staff concern be weighed against a reassuring observation score?	Concern overrides a reassuring score, and the review specifies observation frequency, treatment limits, whom to call and trigger thresholds.

IMF-046-01-0014-en	How should an escalation call be structured, and what should happen if the patient remains unsafe?	State urgency first, then concise context, findings, actions, response and a specific request; persist through the hierarchy if the patient remains unsafe.

IMF-046-01-0015-en	How should uncertainty be documented and safety-netted while avoiding both false reassurance and defensive overtesting?	Record what is known, likely, possible but dangerous, and currently unsupported, then safety-net through observation, repeat examination, trigger thresholds and planned follow-up.

IMF-046-01-0016-en	Which cognitive processes commonly underlie diagnostic error, and what questions does a deliberate pause ask?	Anchoring, premature closure, framing, availability and failure to integrate discordant data; the pause asks what else it could be, what does not fit, what to expect next, and whether treatment changed probability.

IMF-046-01-0017-en	What makes a handover task actionable for the next clinician?	Each task states what, why, when, owner, expected result and response to an abnormal result, confirmed by closed-loop questions and restatement.

IMF-046-01-0018-en	What must clinical notes keep distinct, and how should a patient's behaviour be recorded?	Notes distinguish observation, reports and inference, and describe behaviour without judgement; copied text is reviewed and errors are corrected transparently.

IMF-046-01-0019-en	When does discharge planning begin, and what does stability mean for discharge?	It begins at admission with baseline function, environment and supports; stability means the patient can be managed safely outside current monitoring.

IMF-046-01-0020-en	How should competing recommendations be resolved in a patient with multimorbidity?	Prioritise treatments with meaningful benefit, acceptable burden and alignment with goals, and coordinate specialists so one organ's plan does not destabilise another.

IMF-046-01-0021-en	Why are rehabilitation and social support part of disease treatment after sepsis, surgery or critical illness?	Recovery can involve weakness, cognitive problems, pain, anxiety and financial strain, so function and quality of life must be tracked and treated alongside biomarkers.

IMF-046-01-0022-en	What does a resuscitation decision cover, and what should goals-of-care documentation record?	It addresses cardiopulmonary arrest, not all treatment; record which interventions remain appropriate, who participated, the patient's reasoning and values, and when to review.

IMF-046-01-0023-en	How should recognising that cure is unlikely change the care a patient receives?	It should intensify comfort and coordination rather than signal abandonment, with palliative care running alongside disease-directed treatment.

IMF-046-01-0024-en	After harm, why are standardisation and design preferred to education alone, and how does a just culture judge individual actions?	They are stronger than education alone; a just culture distinguishes human error, risky shortcuts and reckless conduct while preserving accountability.

IMF-046-02-0001-en	Why can a record that contains every historical fact still fail the next clinician?	If it does not show what is dangerous now, what changed, what is uncertain, what response is expected and who owns the next action, the current state cannot be reconstructed.

IMF-046-02-0002-en	Why should a new rash or absent response to antibiotics force revision of the problem representation?	The representation is provisional; such findings should reshape it rather than being appended to an unchanged label.

IMF-046-02-0003-en	Using acute kidney injury as an example, how do causal links reduce duplication in a problem list?	Linking kidney injury to sepsis and nephrotoxins, and to its effects on antibiotic dose and fluid tolerance, shows causes and consequences together instead of as separate problems.

IMF-046-02-0004-en	Why might a diagnosis with no discordant data be less certain than it appears?	It may reflect inadequate testing rather than certainty; predicting what should happen next lets an unexpected trajectory act as evidence that prompts a diagnostic pause.

IMF-046-02-0005-en	Why are timing and specimen quality part of a test order?	Cultures taken after antibiotics, a superficial swab for deep infection, or a troponin without a time relation can answer a different question from the one intended.

IMF-046-02-0006-en	Why does repeating the same intervention without a response model turn treatment into ritual?	A trial is interpretable only with a defined target and timeframe; without them, insufficient delivery, wrong mechanism, irreversible disease or inadequate observation time cannot be considered.

IMF-046-02-0007-en	Why should an escalation call lead with urgency and the requested action?	A request buried in a long chronology is less safe; closed-loop communication then requires the receiver to acknowledge the message and clarify the plan.

IMF-046-02-0008-en	Why is a handover instruction simply to check potassium incomplete?	Handover transfers prospective responsibility, so the task needs why, when, owner, expected result and abnormal action: repeat at eight because replacement finished, and call if outside range.

IMF-046-02-0009-en	What must replace an instruction to restart a held medicine when the patient improves?	A specific condition, such as blood pressure, kidney function, cessation of bleeding, oral intake or days after a procedure, and a named responsible person.

IMF-046-02-0010-en	Why is documenting a patient as aggressive and noncompliant weaker than recording that the patient shouted and left the room?	The first is a judgement that loses context, while the second is an observation; documentation separates observation, reported history and inference.

IMF-046-02-0012-en	Why is automated inbox delivery of a pending result not the same as ownership?	Ownership needs a named reviewer, expected availability, communication method and action threshold; delivery is not ownership if nobody is scheduled to check it.

IMF-046-02-0013-en	Why does longitudinal care need a coordinating generalist to integrate disease-specific plans?	The plans can conflict: tight pressure control can worsen falls, fluid restriction can impair nutrition, and anticoagulation reduces stroke while increasing bleeding, so someone must identify the outcomes that matter most.

IMF-046-02-0014-en	Why is an instruction to be more careful weak prevention after a near miss?	Stronger prevention is matched to the failure mechanism: standardisation, forcing functions, simpler processes, independent checks for high-risk steps and feedback on outcomes.

IMF-047-01-0001-en	What should reasoning about a gastrointestinal presentation establish beyond naming the symptom?	It should localise the process, identify mechanism and tempo, estimate consequence, and recognise haemorrhage, perforation, ischaemia, obstruction, or cancer early.

IMF-047-01-0002-en	What distinguishes oropharyngeal from oesophageal dysphagia clinically?	Oropharyngeal dysphagia impairs initiating a swallow, with coughing, nasal regurgitation, wet voice, or aspiration, whereas oesophageal dysphagia is food sticking after the swallow has been initiated.

IMF-047-01-0003-en	What does the order in which solids and liquids become difficult suggest about the mechanism of dysphagia?	Difficulty first with solids suggests mechanical narrowing, while difficulty with solids and liquids from the outset suggests disordered motility, although the patterns overlap.

IMF-047-01-0004-en	Why does gastro-oesophageal reflux occur, and which factors contribute?	Gastric contents repeatedly cross an incompetent antireflux barrier, helped by transient lower sphincter relaxation, hiatus hernia, obesity, pregnancy, delayed emptying, and impaired clearance.

IMF-047-01-0005-en	Why does persistent acid exposure in reflux matter beyond symptom control?	It can cause erosive oesophagitis, peptic stricture, and metaplastic Barrett oesophagus, which increases adenocarcinoma risk.

IMF-047-01-0006-en	What neural loss underlies achalasia, and how does it disturb oesophageal function?	Loss of inhibitory myenteric neurons impairs lower sphincter relaxation and abolishes organised peristalsis, so regurgitation, weight loss, and aspiration may follow.

IMF-047-01-0007-en	In achalasia, why are both manometry and endoscopy needed, and what do the treatments have in common?	Manometry establishes the motor pattern while endoscopy excludes obstructing cancer; pneumatic dilation and surgical or endoscopic myotomy all reduce outflow resistance.

IMF-047-01-0008-en	Why does dyspepsia not establish that a patient has gastritis?	Gastritis is histological inflammation arising when mucosal defences are overwhelmed by factors such as acid, pepsin, or Helicobacter, whereas dyspepsia is a symptom syndrome that does not prove mucosal injury.

IMF-047-01-0014-en	How does the management of suspected variceal bleeding differ from that of ulcer bleeding?	Proton-pump inhibition supports ulcer haemostasis, whereas suspected variceal bleeding requires vasoactive therapy, antibiotics, and urgent endoscopic control.

IMF-047-01-0015-en	Why is coeliac serology performed while gluten is still being eaten, and why is total immunoglobulin A measured with it?	The enteropathy is triggered by gluten, so testing needs ongoing intake; total immunoglobulin A detects deficiency, in which alternative serology is needed.

IMF-047-01-0017-en	Why does oral rehydration work in many secretory diarrhoeas, and why are antibiotics used selectively?	Sodium-glucose cotransport remains effective in many secretory illnesses; antibiotics are selective because some infections are self-limited and treatment can worsen toxin-mediated disease or resistance.

IMF-047-01-0018-en	What distinguishes the inflammation of ulcerative colitis from that of Crohn disease?	Ulcerative colitis is continuous mucosal inflammation from the rectum proximally; Crohn disease is patchy and transmural anywhere from mouth to anus, with strictures, fistulas, abscesses, and perianal disease.

IMF-047-01-0020-en	Why is irritable bowel syndrome diagnosed positively rather than by repeated exclusion testing?	It is a disorder of gut-brain interaction without structural explanation, so once warning features are assessed, repetitive low-yield investigations mainly reinforce fear.

IMF-048-01-0008-en	In acute liver failure, why is glucose checked repeatedly and sedation avoided where possible?	Hypoglycaemia can follow hepatic failure, and sedation confuses assessment of encephalopathy, which is part of the diagnosis.

IMF-048-01-0010-en	How does the architecture of cirrhosis produce both portal hypertension and reduced function?	Cirrhosis reorganises the liver into regenerative nodules separated by scar, which increases intrahepatic resistance and reduces function.

IMF-048-01-0011-en	Why can cirrhosis go unrecognised, and how does decompensation reveal itself?	Compensated disease may be silent; decompensation appears as ascites, variceal bleeding, encephalopathy, jaundice, infection, or kidney dysfunction.

IMF-048-01-0015-en	What are the components of managing acute variceal bleeding, and when is a transjugular intrahepatic portosystemic shunt considered?	Resuscitation avoiding excessive pressure, vasoactive splanchnic therapy, antibiotics, and endoscopic control; a shunt is considered if bleeding persists or high-risk criteria are met.

IMF-048-01-0017-en	Why is diagnostic paracentesis required for new, worsening, or hospitalised ascites even without abdominal tenderness?	Spontaneous bacterial peritonitis may present only with fever, encephalopathy, or kidney injury and little local tenderness, and sampling also identifies alternative mechanisms.

IMF-048-01-0018-en	How does lactulose treat hepatic encephalopathy, and why is an ammonia level alone insufficient for diagnosis?	Lactulose promotes colonic ammonia disposal and is titrated to regular soft stool; an ammonia concentration by itself neither confirms nor excludes the syndrome.

IMF-048-01-0019-en	What circulatory disturbance underlies hepatorenal syndrome, and what can treatment achieve?	Profound renal vasoconstriction amid systemic and splanchnic vasodilation; albumin plus vasoconstrictor therapy can bridge selected patients to transplantation.

IMF-048-01-0020-en	What is hepatocellular carcinoma surveillance trying to achieve, and what is the limit of alpha-fetoprotein?	It aims to find tumours still suitable for ablation, resection, or transplantation; alpha-fetoprotein supports surveillance or assessment but is not independently diagnostic.

IMF-048-01-0021-en	What distinguishes episodic biliary pain from acute cholecystitis?	Biliary pain comes from transient cystic-duct obstruction without persistent inflammation; cholecystitis causes prolonged pain, fever, local tenderness, and inflammatory change.	Integrated Medical Foundations; chapter 48, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: ed13b8f0b9081eb71864bc32f5dcc5ef87b6d1dba723fdb0eacde59735fa2efd; editorial review pending	imf lang::en chapter::048 module::048-01 review::pending
IMF-048-01-0022-en	Why does cholangitis need urgent biliary drainage, and what are the risks of the usual procedure?	It is infected obstruction, so urgent drainage, usually by endoscopic retrograde cholangiopancreatography, accompanies fluids and antibiotics; the procedure can cause pancreatitis, bleeding, perforation, or infection.

IMF-048-01-0023-en	Why is enzyme height not used to grade acute pancreatitis, and why are routine prophylactic antibiotics not given?	Severity depends on persistent organ failure and complications rather than enzyme height, and routine prophylactic antibiotics do not treat sterile necrosis.

IMF-048-01-0024-en	How do the consequences of chronic pancreatitis shape its management?	Irreversible fibrosis causes exocrine failure, diabetes, and pain, so management includes enzyme replacement with meals, fat-soluble vitamin review, diabetes care, and analgesia.

IMF-048-02-0002-en	What distinguishes predictable from idiosyncratic drug-induced liver injury, and why is rechallenge generally avoided?	Predictable injury is dose-related, as with paracetamol, whereas idiosyncratic injury is delayed; rechallenge can provoke more severe injury.

IMF-048-02-0003-en	In acute liver failure, why is abnormal coagulation not corrected with prophylactic plasma?	Correcting the numbers alone obscures both bleeding-risk assessment and the transplant decision, and adds volume load.

IMF-048-02-0004-en	Why do the kidneys retain sodium in cirrhosis even though total extracellular fluid is expanded?	Splanchnic vasodilation lowers effective arterial volume, so the kidneys perceive underfilling and neurohormonal sodium retention continues.

IMF-048-02-0005-en	Why is cirrhosis a state of both bleeding and thrombosis risk despite prolonged conventional clotting tests?	Conventional tests capture the loss of procoagulant factors but not the parallel loss of anticoagulant factors, leaving a fragile rebalanced state.

IMF-048-02-0006-en	Which findings in suspected peritonitis point to secondary peritonitis or perforation rather than the spontaneous form, and what follows?	Polymicrobial culture, extreme protein or glucose change, failure to respond, and localised peritoneal signs; they lead to cross-sectional imaging and surgical assessment.

IMF-048-02-0007-en	Why is albumin replaced after large-volume paracentesis?	Large-volume drainage relieves pressure and breathing but can worsen circulatory dysfunction unless albumin is replaced according to volume and protocol.

IMF-048-02-0008-en	Why is volume restricted when resuscitating variceal bleeding, and what is the trade-off of an early transjugular shunt?	Excessive volume raises portal pressure; an early shunt benefits selected high-risk bleeding but can worsen encephalopathy by increasing portal bypass.

IMF-048-02-0009-en	Why can blood ammonia not confirm or stage hepatic encephalopathy, and how does lactulose help?	Ammonia contributes but its blood concentration correlates poorly with the syndrome; lactulose traps nitrogen in the colon and accelerates its elimination.

IMF-048-02-0010-en	Why is kidney injury in cirrhosis not assumed to be hepatorenal syndrome, and what supports that diagnosis?	Volume loss, sepsis, nephrotoxins, obstruction, glomerular disease, and acute tubular injury are assessed first; albumin challenge and withdrawal of contributors support hepatorenal physiology.

IMF-048-02-0011-en	In metabolic steatotic liver disease, why are non-invasive fibrosis scores and elastography used?	Fibrosis stage predicts outcome more strongly than steatosis, and these tools identify who needs specialist assessment or surveillance without biopsying everyone.

IMF-048-02-0012-en	Why can antibiotics alone not treat cholangitis?	Cholangitis is sepsis behind an obstructed duct, which antibiotics cannot reliably sterilise without drainage, so urgent decompression follows resuscitation.

IMF-049-01-0012-en	Before detailed examination, what immediate threats are sought, and why is airway included?	Shock, sepsis, major bleeding, dehydration, perforation, obstruction, acute liver failure and metabolic disturbance; haematemesis or reduced consciousness creates airway risk.

IMF-049-01-0015-en	Why should bowel sounds not be used alone to diagnose ileus or obstruction?	Their interpretation has limited accuracy: absent sounds alone do not diagnose ileus, and high-pitched sounds do not prove obstruction.

IMF-049-01-0018-en	What governs whether digital rectal examination is performed, and how is it done?	It is selective, done only when it will affect care; explain, obtain consent, use a chaperone per policy, inspect first, then assess tenderness, mass, stool, blood and sphincter.

IMF-049-01-0020-en	Why must laboratory results be interpreted with trends and pretest probability rather than as single values?	A normal lactate does not exclude early mesenteric ischaemia, mild lipase elevation occurs outside pancreatitis, and positive faecal occult blood does not localise bleeding.

IMF-049-01-0022-en	What distinguishes the roles of ultrasound, computed tomography and computed tomographic angiography in abdominal imaging?	Ultrasound suits gallstones, biliary dilation, ascites, portal flow and many pelvic questions; CT evaluates obstruction, inflammation, perforation, abscess, cancer and trauma; CT angiography is urgent for active bleeding or mesenteric ischaemia.

IMF-049-01-0024-en	Why is reassessment after treatment part of diagnosis, particularly in frail, pregnant or immune-suppressed patients?	These patients may show muted signs, so recorded changes in pain, observations, examination, urine, laboratory trends and response reveal what a single examination misses.

IMF-049-02-0001-en	Why is visceral pain poorly localised, and how does embryological region predict its site?	Afferents converge across spinal segments; foregut structures tend to give epigastric pain, midgut periumbilical pain, and hindgut lower abdominal pain.

IMF-049-02-0002-en	Why is pain out of proportion to early palpation findings a warning for mesenteric ischaemia?	Mucosa and muscle become hypoxic before the peritoneum is inflamed, so pain precedes peritoneal signs.

IMF-049-02-0003-en	What do colicky waves of pain imply mechanically, and how does biliary pain differ?	Contraction against intermittent or fixed resistance in bowel, ureter or biliary tract; biliary pain is often steady after onset.

IMF-049-02-0005-en	Why can the colour of gastrointestinal blood not reliably indicate the bleeding site or severity?	Coffee-ground material can coexist with active bleeding, melaena can arise from small bowel or right colon, and brisk upper haemorrhage can cause bright rectal blood.

IMF-049-02-0006-en	Why should blood loss not be calculated from a single haemoglobin value during resuscitation?	The rate of haemoglobin decline also reflects dilution by infused fluid, so trends must be read in a time series.

IMF-049-02-0009-en	Why is pregnancy testing part of abdominal diagnosis, and why not rely on relationship status or reported contraception?	Ectopic pregnancy, miscarriage, torsion and pregnancy physiology change imaging and treatment, and history alone cannot exclude pregnancy, so it is asked and tested respectfully.

IMF-049-02-0012-en	How does bowel distension progress to perforation, and what change in pain signals this?	Raised wall tension impedes venous and lymphatic flow, increasing oedema and secretion until the mucosal barrier fails; pain changing from colicky to constant suggests ischaemia.

IMF-049-02-0013-en	Why does the absence of free subdiaphragmatic gas not settle whether a perforation needs intervention?	Gas may be absent with contained, retroperitoneal or small perforations, and the real question is whether contamination, sepsis, leak and tissue viability can be controlled without operation.

IMF-049-02-0014-en	Why is improvement in pain not sufficient for safe discharge after undifferentiated abdominal symptoms?	The patient must also tolerate intake, stay hydrated, mobilise, understand medication and lack evolving warnings, with explicit return triggers and owners for pending results.

IMF-050-01-0001-en	Why is body size alone a misleading guide to whether a person is malnourished?	Malnutrition includes inflammatory catabolism and excess adiposity with poor nutrient quality, so a person with obesity can still lose muscle and become severely malnourished.

IMF-050-01-0002-en	Why does prolonged negative energy balance consume muscle and organ protein?	The body stores glycogen and triglyceride but has no inert protein reserve, so protein must come from functioning muscle and organs.

IMF-050-01-0003-en	How does the hormonal response to fasting mobilise fuel, and what limits protein loss?	Falling insulin with glucagon and stress hormones promotes glycogenolysis, lipolysis, gluconeogenesis, and ketone production; brain use of ketones limits but does not prevent protein loss.

IMF-050-01-0016-en	Why is thiamine given before or with carbohydrate in high-risk patients, and what must not be delayed?	Thiamine is required for oxidative carbohydrate metabolism, and deficiency can cause Wernicke encephalopathy; emergency glucose for hypoglycaemia must still not be delayed.

IMF-050-01-0018-en	What happens physiologically when insulin-driven refeeding follows prolonged undernutrition?	Phosphate, potassium, and magnesium move into cells, thiamine demand increases, sodium and water are retained, and metabolism expands, which can cause arrhythmia, heart failure, and respiratory weakness.

IMF-050-01-0020-en	Why is refeeding syndrome a risk whichever feeding route is chosen?	It is driven by the insulin response to renewed energy supply, so it can occur by oral, enteral, parenteral, or intravenous glucose routes.

IMF-050-01-0024-en	What does metabolic surgery demand after the operation, and what risks does rapid weight loss bring?	It requires lifelong nutrition, micronutrient monitoring, and psychosocial follow-up; rapid loss can increase gallstones and expose sarcopenia.

IMF-050-02-0001-en	Why can body weight conceal severe muscle loss?	Weight is a mixture of fat, muscle, bone, organs, water, and luminal contents, so oedema, ascites, resuscitation, tumour, or obesity can mask a fall in muscle.

IMF-050-02-0002-en	How does catabolism in critical illness differ from uncomplicated fasting?	In fasting, falling insulin and ketone adaptation reduce amino-acid demand; in critical illness, catecholamines, cortisol, glucagon, and cytokines accelerate proteolysis and hepatic glucose production despite feeding.

IMF-050-02-0004-en	Why are predictive equations for energy requirement unreliable, and what can measure it instead?	They err in obesity, oedema, fever, ventilation, burns, or changing illness; indirect calorimetry measures oxygen consumption and carbon-dioxide production when precision matters and conditions permit.

IMF-050-02-0006-en	Why should albumin not be used as a nutritional scoreboard?	Inflammation, capillary escape, dilution, kidney or gut loss, and liver failure lower it, so a low value predicts illness severity without proving inadequate protein intake, and infused albumin does not rebuild muscle.

IMF-050-02-0008-en	Why can broad empirical micronutrient replacement cause harm, as zinc illustrates?	Replacement itself can cause toxicity, and excess zinc can lead to copper deficiency with anaemia, neutropenia, and myeloneuropathy, so testing and dosing follow risk.

IMF-050-02-0009-en	Why do normal serum electrolytes not exclude refeeding risk after starvation?	Total-body phosphate, potassium, and magnesium are depleted despite normal serum values, and insulin released by carbohydrate drives them into cells, exposing the deficit.

IMF-050-02-0012-en	How is sarcopenic obesity missed, and how does it change the treatment goal?	Body mass index alone does not show reduced muscle mass and strength, so the goal becomes preserving function, with protein, resistance exercise, and falls prevention built into weight loss.

IMF-051-01-0016-en	Why is catheter-associated infection diagnosed from symptoms rather than cloudy or odorous urine?	Catheters bypass defence and develop biofilm, so urine appearance alone does not establish infection; compatible symptoms are required.

IMF-051-01-0017-en	Through what mechanism does urinary obstruction damage the kidney?	It raises upstream pressure, which can reduce filtration, impair concentration, cause infection, and eventually atrophy renal tissue.

IMF-051-01-0018-en	Why should repeated blind attempts at difficult catheterisation be avoided?	They can create false passages; difficult or traumatic catheterisation requires experienced help, and suprapubic drainage may be needed.

IMF-051-01-0019-en	Why is post-obstructive diuresis replaced as a considered proportion rather than matched automatically?	It may reflect excretion of retained salt and water or impaired tubular concentration; losses are recorded closely and a proportion replaced according to volume status and electrolytes.

IMF-051-01-0020-en	Why does ultrasound suit stone assessment in pregnancy, and what does non-contrast computed tomography offer?	Ultrasound avoids radiation and often detects hydronephrosis, while non-contrast computed tomography is highly sensitive for stones.

IMF-051-02-0001-en	Why is symptom intensity a poor guide to the severity of urinary obstruction?	Slowly progressive bilateral obstruction may be painless, while a small moving ureteric stone causes extreme colic.

IMF-051-02-0002-en	Which features change ureteric colic from an uncomplicated syndrome to a dangerous one, and what might they signify?	Constant focal tenderness, fever, rigors, hypotension, confusion, anuria or acute kidney injury suggest infection, infarction, rupture, or threatened renal function.

IMF-051-02-0003-en	Why does infected obstruction progress rapidly to septic shock, and why can bladder urine be sterile?	Pressure and impaired flow reduce antibiotic delivery and bacterial clearance; when the infected system is completely blocked, its urine does not reach the bladder.

IMF-051-02-0004-en	How do urine volume, sodium intake and citrate each influence calcium stone formation?	Low urine volume concentrates every lithogenic solute, sodium intake increases urinary calcium, and citrate complexes calcium and inhibits crystallisation.

IMF-051-02-0005-en	How do sympathetic, somatic and parasympathetic pathways differ between bladder storage and emptying?	During storage, sympathetic and somatic pathways keep the outlet closed while parasympathetic activity is restrained; emptying needs detrusor contraction with bladder neck, sphincter and pelvic-floor relaxation.

IMF-051-02-0006-en	Why is chronic high-pressure retention particularly dangerous compared with acute retention?	Acute retention is painful with a palpable bladder, but chronic high-pressure retention can be silent until kidney failure or overflow leakage appears.

IMF-051-02-0007-en	In anuria with an empty bladder, how does upper-tract imaging separate the likely causes?	Bilateral hydronephrosis suggests upper-tract obstruction; no hydronephrosis suggests circulatory failure or parenchymal injury, although early obstruction may show little dilatation.

IMF-051-02-0008-en	Why is matching every millilitre of post-obstructive diuresis harmful, and what is the opposite risk?	Full matching can perpetuate the diuresis, whereas inadequate replacement causes hypovolaemia and shock, so a clinically judged portion is replaced.

IMF-051-02-0009-en	Why can nocturia arise without bladder disease, and what record best reveals its mechanism?	Sleep apnoea, heart failure, oedema mobilisation, insomnia or reduced concentrating ability can cause it; a chart of intake, time, voided volume, urgency and leakage reveals mechanism.

IMF-051-02-0010-en	Why is urinary infection not diagnosed from culture alone, and what harm do repeated empirical antibiotics cause?	Diagnosis needs a compatible syndrome plus testing because other conditions mimic infection; repeated empirical courses without culture obscure the cause and select resistance.

IMF-051-02-0013-en	Why is neurogenic lower-tract dysfunction managed to protect the kidneys, not only continence?	It can produce dangerous high-pressure storage, detrusor-sphincter dyssynergia or ineffective emptying, and symptoms may underestimate the pressure.

IMF-051-02-0014-en	While awaiting stone passage, why is symptom resolution not accepted as proof that obstruction has cleared?	Safe care is complete only when kidney function and the underlying cause are confirmed resolved, so repeat imaging or review is arranged rather than relying on symptoms.

IMF-052-01-0005-en	How does the gonadotropin pattern distinguish primary from secondary hypogonadism?	Primary hypogonadism is testicular failure, so low testosterone releases feedback and gonadotropins rise; secondary disease lies in hypothalamus or pituitary, so drive is deficient.

IMF-052-01-0017-en	Which penile lesion requires biopsy, and which factors raise penile cancer risk?	A persistent ulcer, mass, bleeding, or skin change needs biopsy; smoking, phimosis, and oncogenic human papillomavirus increase risk.

IMF-052-01-0018-en	In suspected testicular torsion, why should surgery not wait for imaging?	Twisting obstructs venous then arterial flow, salvage falls rapidly with time, and no clinical sign safely excludes torsion, so high suspicion warrants exploration and bilateral fixation.

IMF-052-01-0019-en	Which features favour epididymitis over torsion, and why is torsion still reconsidered?	Gradual onset, posterior tenderness, urinary or urethral symptoms, and sometimes fever favour epididymitis, but torsion is reconsidered while uncertainty remains because no sign safely excludes it.

IMF-052-01-0020-en	What clue suggests Fournier gangrene before skin changes look severe, and what management is essential?	Pain beyond visible findings in rapidly progressive genital or perineal necrosis; resuscitation, broad antibiotics, and immediate debridement are essential.

IMF-052-01-0021-en	Which varicocele features raise concern for secondary obstruction?	A new right-sided, non-reducing, or supine-persistent varicocele, since typical varicoceles are left-sided dilated pampiniform veins.

IMF-052-01-0022-en	How is a solid intratesticular mass handled, and why do normal tumour markers not reassure?	It is treated as malignant until urgent ultrasound and markers evaluate it, without trans-scrotal biopsy; radical inguinal orchidectomy diagnoses it, and markers can be normal in cancer.

IMF-052-01-0023-en	Why do benign prostatic hyperplasia symptoms not correlate with gland size alone, and how do the two drug classes differ?	Symptoms depend on smooth-muscle tone, narrowing, bladder compensation, and nerves; alpha-one blockers relax tone quickly, whereas five-alpha-reductase inhibitors shrink larger glands over months.

IMF-052-01-0024-en	Why is prostate cancer screening a preference-sensitive decision?	Early detection can prevent some deaths, but prostate-specific antigen also rises with benign causes, bringing false positives, biopsy harms, overdiagnosis, and treatment-related dysfunction.

IMF-052-02-0001-en	Why should libido, erection, ejaculation, orgasm, and fertility be assessed as separable functions?	They are related but distinct, so a person can have normal erections with impaired spermatogenesis, or low desire with intact genital physiology.

IMF-052-02-0002-en	Why does continuous rather than pulsatile gonadotropin-releasing hormone exposure lower testosterone?	The hormone is normally released in pulses, and continuous exposure suppresses pituitary gonadotropins, removing the drive to Leydig cells.

IMF-052-02-0003-en	Why can a total testosterone concentration misrepresent biologically available hormone?	Most circulating testosterone is protein-bound, and sex-hormone-binding globulin changes with age, obesity, thyroid and liver disease, insulin, and medications.

IMF-052-02-0004-en	What do low or inappropriately normal gonadotropins with low testosterone imply, and what follows?	Hypothalamic or pituitary suppression, prompting assessment of prolactin, pituitary symptoms, opioids, glucocorticoids, obesity, undernutrition, and systemic disease.

IMF-052-02-0005-en	In secondary hypogonadism with fertility wishes, why is exogenous testosterone avoided?	It suppresses sperm production, so treating the cause and restoring endogenous gonadotropin drive, including gonadotropins or selective receptor modulation under specialists, preserves fertility.

IMF-052-02-0006-en	Why is irreversible infertility not concluded from semen analysis immediately after stopping testosterone or steroids?	Recovery of spermatogenesis takes months, and anabolic steroids can cause prolonged secondary hypogonadism after cessation.

IMF-052-02-0007-en	How does nitric oxide lead to blood being trapped in the penis during erection?	Nitric oxide raises cyclic guanosine monophosphate, relaxing cavernosal smooth muscle; arterial inflow expands sinusoids, which compress subtunical veins.

IMF-052-02-0008-en	Why do preserved morning or masturbation erections not prove a purely psychological cause?	They suggest preserved physiology, but physical contributors can coexist, so situational variability, performance fear, and relationship stress are explored without dismissing them.

IMF-052-02-0009-en	When a phosphodiesterase type-five inhibitor appears to fail, what should be reviewed instead of escalating the dose?	Timing, food effect, dose and repeated correct trials, testosterone where indicated, vascular disease, neurological injury, and alternative devices, because unsafe escalation adds risk.

IMF-052-02-0010-en	Why do alpha blockers or pelvic surgery cause low-volume or dry orgasm?	Ejaculation needs sympathetic emission and bladder-neck closure; impairing these gives failed emission or retrograde ejaculation with sperm in post-ejaculatory urine.

IMF-052-02-0011-en	Why must systemic treatment, including in sickle cell disease, not delay corporal decompression in ischaemic priapism?	Stagnant hypoxic blood in a closed compartment causes time-dependent smooth-muscle necrosis and later fibrosis, and systemic measures do not substitute for local decompression.

IMF-052-02-0012-en	Why are both testes fixed after torsion, and why can urinary symptoms or partial relief not exclude it?	Anatomical predisposition is commonly bilateral; torsion causes infarction within hours, and age, urinary symptoms, partial relief, or one normal sign cannot exclude it.

IMF-052-02-0013-en	Why is trans-scrotal biopsy avoided for a suspected testicular tumour?	It disrupts lymphatic drainage and staging, so radical inguinal orchidectomy is used for both diagnosis and treatment.

IMF-052-02-0014-en	In azoospermia, what distinguishes absent production from obstruction, and why can the cause matter for offspring?	Testicular size, gonadotropins, genetics, and examination separate them; severe oligospermia or absent vas deferens can reveal chromosomal or cystic-fibrosis-related conditions.

IMF-053-01-0002-en	How does follicular growth drive both endometrial proliferation and ovulation?	Growing follicles produce oestradiol, which proliferates the endometrium, and sustained high oestradiol triggers the luteinising-hormone surge that causes ovulation.

IMF-053-01-0012-en	Why is vaginal discharge not diagnosed from history alone?	History is unreliable across physiological, infective, atrophic, fistula, foreign-body, and malignant causes, so examination and microscopy, pH, nucleic-acid testing, or culture are chosen by syndrome.

IMF-053-01-0013-en	Why is pelvic inflammatory disease treated empirically on clinical findings rather than after confirmation?	Lower abdominal pain with cervical motion, uterine, or adnexal tenderness supports treatment once pregnancy and emergencies are considered, because delay increases infertility, ectopic pregnancy, abscess, and chronic pain.

IMF-053-01-0018-en	When should infertility be assessed earlier than the usual period of trying, and who is evaluated?	With advanced reproductive age, irregular cycles, known pelvic or testicular disease, previous gonadotoxic treatment, or other risk; both partners are evaluated concurrently.

IMF-053-01-0020-en	Why are combined oestrogen-progestogen methods unsuitable in selected migraine, smoking, vascular, hepatic, postpartum, and cancer contexts?	Oestrogen increases thrombosis risk, even though combined methods suppress ovulation and improve bleeding, pain, acne, and endometriosis symptoms.

IMF-053-01-0021-en	What do progestogen-only and copper intrauterine methods gain by avoiding oestrogen, and what trade-offs remain?	They avoid oestrogen, but progestogen-only methods differ in bleeding, bone, weight, and return-to-fertility effects, and copper devices may increase bleeding and pain.

IMF-053-01-0022-en	How is an emergency contraceptive chosen, and does it affect an established pregnancy?	A copper device or oral agent is chosen by time, weight, interactions, ovulation timing, and access, and it does not disrupt an implanted pregnancy.

IMF-053-01-0023-en	What distinguishes local vaginal oestrogen from systemic menopausal hormone therapy?	Local vaginal oestrogen has low systemic exposure and treats urogenital symptoms; systemic therapy best treats vasomotor symptoms but needs endometrial protection when a uterus is present.

IMF-053-01-0024-en	Why is ovarian cancer easy to miss, and how should persistent warning features be handled?	It often causes persistent bloating, early satiety, pelvic pressure, urinary or weight change rather than one specific symptom; persistence warrants examination, imaging, biopsy, and referral.

IMF-053-02-0001-en	Why is a positive pregnancy test without a confirmed intrauterine pregnancy followed as a pregnancy of unknown location?	It should not be dismissed as too early; haemodynamics, pain, bleeding, transvaginal ultrasound, and the human chorionic gonadotropin trend are integrated, since no single value proves normality.

IMF-053-02-0002-en	Why does unreliable follow-up change the choice between medical, expectant, and surgical management of a possible ectopic pregnancy?	The safety of each option depends on stability, imaging, hormone values, contraindications, and reliable capacity to return, so safety changes when follow-up cannot be assured.

IMF-053-02-0003-en	Why does gonadotropin drive increase in the early follicular phase?	Falling progesterone and oestradiol release gonadotropin suppression, allowing follicle-stimulating hormone to recruit follicles.

IMF-053-02-0004-en	What sequence of vascular and inflammatory events sheds the functional layer when implantation fails?	Luteal regression withdraws hormones, spiral arterioles constrict, inflammatory mediators activate, and the functional layer sheds.

IMF-053-02-0005-en	Why does a normal haemoglobin not settle the impact of heavy menstrual bleeding?	A normal-looking haemoglobin does not exclude depleted iron stores, so iron deficiency must be assessed directly.

IMF-053-02-0007-en	How do tranexamic acid and hormonal regimens each act in acute heavy uterine bleeding?	Tranexamic acid reduces fibrinolysis, while hormonal regimens stabilise the endometrium when appropriate.

IMF-053-02-0009-en	Why does adnexal torsion produce ovarian oedema before infarction?	The twisted vascular pedicle obstructs venous outflow before arterial inflow, so the ovary swells and then infarcts.

IMF-053-02-0010-en	Why do negative nucleic-acid tests not exclude pelvic inflammatory disease?	They identify important sexually transmitted pathogens but cannot exclude polymicrobial upper-tract infection, and the diagnosis is kept clinical to prevent tubal injury.

IMF-053-02-0011-en	Why does endometriosis pain severity track poorly with visible lesion volume?	Pain reflects lesion location, nerve involvement, central sensitisation, pelvic-floor response, inflammation, and psychosocial burden more than visible volume.

IMF-053-02-0012-en	In amenorrhoea with low oestradiol, how do gonadotropin levels localise the problem?	High gonadotropins indicate primary ovarian insufficiency, whereas low or normal gonadotropins suggest hypothalamic or pituitary suppression.

IMF-053-02-0013-en	Why is withdrawal bleeding on combined hormonal pills misleading in functional hypothalamic amenorrhoea?	The pill creates withdrawal bleeding without correcting the energy deficit, while low oestradiol continues to compromise bone, cardiovascular physiology, fertility, and genital tissue.

IMF-053-02-0014-en	Why is repeated empirical treatment for presumed candidiasis risky in persistent vulval symptoms?	It can delay recognition of lichen sclerosus, contact dermatitis, herpes, pre-cancerous change, and cancer, so the skin is inspected and persistent lesions are biopsied.

IMF-054-01-0002-en	What does a positive human chorionic gonadotropin test establish, and what does it not establish?	It confirms trophoblastic activity but does not by itself locate the pregnancy or prove viability; early ultrasound identifies location and cardiac activity.

IMF-054-01-0004-en	Why should anticonvulsants or other essential treatment not be withdrawn abruptly when pregnancy is confirmed?	Abrupt withdrawal of critical treatment such as anticonvulsants, steroids or psychiatric therapy may carry more risk than the drug exposure itself, so medicines are reconciled rather than simply stopped.

IMF-054-01-0007-en	Why do normal pregnancy adaptations make haemorrhage, embolism, infection and cardiac disease more dangerous?	Raised cardiac output and heart rate, lower systemic resistance, slowed gut motility and a clotting shift toward thrombosis reduce the reserve available for these events.

IMF-054-01-0009-en	Why do an absent risk factor and a low hormone level not exclude a dangerous ectopic pregnancy?	Many patients with ectopic pregnancy have no risk factor, and rupture can occur even with low hormone levels.

IMF-054-01-0012-en	What processes give rise to pre-eclampsia, and why can it affect many organs?	It arises from abnormal placentation, endothelial dysfunction, vasoconstriction, inflammation and capillary leak, so dysfunction can involve kidney, liver, brain, blood or placenta.

IMF-054-01-0015-en	Why do insulin requirements change after placental delivery, and why is glucose reassessed postpartum?	Requirements fall sharply once the placenta, the source of the resistance-raising hormones, is delivered; glucose is reassessed because future type two diabetes risk remains high.

IMF-054-02-0005-en	How does inadequate spiral-artery remodelling lead to pre-eclampsia, and why can placental flow be poor despite high maternal pressure?	Inadequate invasion and remodelling cause placental ischaemia and release antiangiogenic and inflammatory signals that injure maternal endothelium, so maternal pressure can be high while placental flow remains poor.

IMF-054-02-0007-en	Why can pre-eclampsia be diagnosed without proteinuria?	It is a multisystem placental endothelial disease, so new hypertension after mid-pregnancy with kidney, liver, neurological, haematological, pulmonary or placental dysfunction meets the syndrome.

IMF-054-02-0010-en	Why is fetal heart monitoring not read as a direct measure of fetal oxygenation?	It reflects the autonomic response to oxygenation, so baseline, variability, accelerations, decelerations, contractions, gestation, medicines and context are interpreted together.

IMF-054-02-0011-en	Why is traction on the fetal head avoided in shoulder dystocia, and what is used instead?	Traction does not release the shoulder and can injure the brachial plexus; maternal positioning, suprapubic pressure, internal rotation or posterior-arm delivery are used, and fundal pressure is avoided.

IMF-054-02-0012-en	Why can an apparently mild fall in fibrinogen indicate severe obstetric haemorrhage?	Fibrinogen falls early in obstetric haemorrhage, and because its reference range is higher in pregnancy, a value that looks mildly low may reflect severe disease.

IMF-054-02-0013-en	Why should the physiological tachycardia and raised white-cell count of pregnancy not be used to dismiss sepsis?	Fever may not be prominent, so tachycardia, tachypnoea, hypotension, altered consciousness, oliguria and fetal tachycardia are early signs, and change over time and organ function carry more weight.

IMF-054-02-0014-en	Why is breastfeeding not automatically stopped when a mother needs a medicine?	Most medicines can be continued; safety depends on milk transfer, infant age, absorption, half-life, toxicity, alternatives and maternal need, and a blanket stop risks an untreated mother or unwanted weaning.

IMF-055-02-0008-en	How does acute angle closure raise pressure, and what does definitive laser treatment relieve?	Aqueous cannot reach or drain through the trabecular meshwork, so pressure rises abruptly; laser relieves pupillary block, and the fellow eye may also need prevention.

IMF-056-01-0024-en	Why can a bedside swallowing screen not exclude aspiration, and what is needed instead?	It only estimates risk and misses silent aspiration, which requires instrumental assessment by fibreoptic endoscopic or videofluoroscopic study.

IMF-056-02-0001-en	Why does an air-bone gap support conductive hearing loss?	Air-conduction thresholds include both external/middle-ear and cochlear pathways, while bone conduction bypasses the external and middle ear, so a gap localises the deficit before the cochlea.

IMF-056-02-0002-en	Why does the Weber test lateralise toward the affected ear in conductive loss, and how do findings differ in unilateral sensorineural loss?	Conductive loss reduces ambient masking in that ear, and Rinne may show bone exceeding air; in unilateral sensorineural loss Weber tends away and Rinne usually remains air greater than bone.

IMF-056-02-0003-en	Why does normal otoscopy not make sudden unilateral hearing loss benign?	Sudden sensorineural loss is often mistaken for wax or congestion, and because corticosteroid benefit is time-sensitive it still needs urgent audiometry and otology.

IMF-056-02-0005-en	Why does a unilateral middle-ear effusion in an adult prompt examination of the nasopharynx?	Middle-ear ventilation depends on the Eustachian tube, so an adult unilateral effusion may reflect nasopharyngeal obstruction, including tumour.

IMF-056-02-0006-en	Why does a sudden unilateral peripheral vestibular loss produce vertigo and nystagmus?	Paired labyrinths normally generate a balanced resting signal; losing one side creates an asymmetry that the brain interprets as rotation.

IMF-056-02-0007-en	What does a catch-up saccade on head impulse indicate, and why can central lesions escape this test?	It shows a deficient peripheral vestibulo-ocular reflex on that side; central lesions can preserve the reflex while disrupting gaze holding, skew, smooth pursuit or coordination.

IMF-056-02-0008-en	Why is vertigo classified by timing and triggers, and why is 'worse with movement' unhelpful?	Duration and provocation separate positional, episodic and continuous syndromes, whereas nearly every vestibular syndrome worsens when the head moves.

IMF-056-02-0011-en	Why does a button battery in the nose, ear or oesophagus need urgent removal, and why avoid blind attempts?	Current and alkaline injury cause rapid tissue necrosis; repeated blind extraction pushes the object deeper and increases bleeding and oedema.

IMF-056-02-0012-en	In Ludwig angina, why can sedation precipitate airway loss?	Sedation removes the compensatory muscle tone holding the airway open, so experienced awake or surgical airway plans may be required.

IMF-056-02-0013-en	Why are stridor loudness and preserved oxygen saturation unreliable guides to airway severity?	A quieter stridor can mean exhaustion, and oxygenation can be maintained while narrowing progresses, then fall abruptly just before complete obstruction.

IMF-056-02-0014-en	Why does nil by mouth or a feeding tube not remove the risk of aspiration pneumonia?	Aspiration of saliva and refluxed material continues, and pneumonia depends on oral bacterial load, volume, cough, activity, immunity, tube feeding and sedation, so mouth care and posture still matter.

IMF-057-01-0001-en	Why can dental disorders and oral lesions matter far beyond the mouth?	Dental disorders can progress to deep-neck infection, sepsis, airway compromise, or tooth loss, and oral lesions can reveal haematological, immune, endocrine, nutritional, infectious, gastrointestinal, or malignant disease.

IMF-057-01-0003-en	Why does reduced salivary flow lead to caries, candidiasis, and periodontal disease?	Saliva normally buffers acid, supports remineralisation, clears food, and restrains microbes, so reduced flow removes these protections.

IMF-057-01-0004-en	Why does caries risk reflect how often fermentable carbohydrate is eaten, not just how much sugar?	Each exposure lets biofilm acid demineralise enamel; salivary buffering, mineral exchange, and fluoride can reverse early injury, but repeated low pH produces cavitation.

IMF-057-01-0007-en	How does pulp necrosis lead to a periapical abscess, and how does the abscess present?	Necrotic pulp permits apical infection; the resulting periapical abscess causes local tenderness and swelling and may drain through a sinus.

IMF-057-01-0008-en	Why are repeated antibiotic courses the wrong answer to contained pulp disease?	Antibiotics do not cure it; without drainage or extraction they delay cure and select resistance, so they are reserved for spreading infection, systemic involvement, immune risk, or guideline-defined situations.

IMF-057-01-0015-en	What distinguishes aphthous ulcers from recurrent herpes simplex, and when do aphthae prompt a systemic search?	Aphthae are shallow painful ulcers without preceding vesicles; recurrent herpes gives clustered vesicles and ulcers on keratinised mucosa. Frequent, severe, or atypical aphthae suggest deficiency, bowel, or immune disease.

IMF-057-02-0001-en	Why can a dental infection threaten structures far from the tooth?	Cavitated enamel cannot repair, pulp lies within a rigid chamber, and infection can track along roots and fascial planes toward orbit, neck, mediastinum, or airway.	Integrated Medical Foundations; chapter 57, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: e7b294e1a2bd774956108144f000add17bb08b01f04bb4a1d84c7db3c73fdefd; editorial review pending	imf lang::en chapter::057 module::057-02 review::pending
IMF-057-02-0002-en	Why does subjective xerostomia deserve preventive treatment even before measured flow falls?	Saliva is an active protective fluid that buffers plaque acid, supports remineralisation, lubricates, and limits organisms, and dryness can be felt before measured flow declines.

IMF-057-02-0003-en	Why can a slowly consumed sweet drink be more damaging than the same amount taken with a meal?	Each exposure creates another acidic interval that lowers plaque pH, and enamel dissolves when demineralisation exceeds saliva- and fluoride-supported repair.

IMF-057-02-0004-en	Why may tooth pain lessen as pulp becomes necrotic, and what does percussion tenderness then indicate?	Necrosis may temporarily reduce pain while infection extends through the apical foramen; percussion tenderness reflects periodontal-ligament inflammation around the root.

IMF-057-02-0005-en	Why cannot antibiotics substitute for root-canal treatment, drainage, or extraction of an infected tooth?	They penetrate poorly into necrotic avascular pulp, so they only weaken symptoms temporarily while the causative tooth remains, and add resistance, diarrhoea, allergy, and Clostridioides infection.

IMF-057-02-0007-en	What does trismus suggest in odontogenic infection, and how should red flags change management?	Trismus suggests masticator or deep-space involvement; red flags such as floor-of-mouth elevation, drooling, or voice change need emergency surgical and airway assessment, not another outpatient antibiotic course.

IMF-057-02-0008-en	Why are sedation and supine positioning dangerous in Ludwig angina?	The firm, elevated floor of mouth pushes the tongue upward and backward, stridor and desaturation appear late, and sedation or lying flat can precipitate complete obstruction.

IMF-057-02-0009-en	How can smoking mislead the assessment of periodontal disease?	Smoking can mask gingival bleeding while accelerating periodontal destruction, so reduced bleeding does not mean less disease.

IMF-057-02-0010-en	How does the site of recurrent oral ulceration help distinguish aphthae from herpes?	Recurrent aphthae occur on non-keratinised mucosa, whereas recurrent herpes usually affects keratinised attached mucosa after grouped vesicles.

IMF-057-02-0011-en	Why does oral mucositis during neutropenia need more concern than its appearance suggests?	Mucositis causes pain, bleeding, reduced intake, and an entry point for infection, and it becomes severe during neutropenia even when it looks mild.

IMF-057-02-0013-en	Why can acidic sweets used to stimulate saliva backfire in a patient with dry mouth?	Their acid worsens erosion and caries, so sugar-free chewing stimulation is used instead when glands retain function.

IMF-057-02-0014-en	Why are anticoagulants not stopped or reversed reflexively for post-extraction bleeding?	Thrombosis risk may exceed local bleeding risk, and most bleeding is controlled locally, so drug, indication, last dose, kidney, platelet, and liver status are checked and care is coordinated.

IMF-058-01-0001-en	Why should immune care identify the defective pathway and prevent complications before starting suppression?	Immune failure can cause allergy, autoimmunity, immunodeficiency, infection, rejection or malignancy, and immune-modifying treatments themselves cause infection, cancer, metabolic, haematological and organ toxicities.

IMF-058-01-0002-en	How does an allergen trigger immediate hypersensitivity at the cellular level?	It cross-links immunoglobulin E bound to mast cells and basophils, releasing histamine, tryptase, leukotrienes, prostaglandins and cytokines.

IMF-058-01-0003-en	How do released mast-cell mediators produce urticaria, bronchospasm and shock?	They cause vasodilation, capillary leak, smooth-muscle contraction, mucus, itch and sensory activation, which together produce urticaria, angioedema, bronchospasm, gastrointestinal symptoms and shock.

IMF-058-01-0004-en	What distinguishes antibody-mediated cytotoxic, immune-complex and delayed hypersensitivity reactions?	Cytotoxic antibodies target cells or matrix, activate complement or alter receptors; immune complexes deposit and inflame vessels, glomeruli, joints and skin; delayed reactions are T-cell mediated and appear hours to days after exposure.

IMF-058-01-0005-en	Why must a reaction history distinguish true allergy from intolerance, toxicity or vasovagal episodes?	An inaccurate allergy label can deny first-line therapy and increase complications, so adverse effects, intolerance, toxicity, vasovagal episodes and coincidence must be separated from allergy.

IMF-058-01-0006-en	Why should skin-prick and specific immunoglobulin E tests target plausible triggers rather than broad panels?	They detect sensitisation, which does not always mean clinical allergy, so broad food panels create false positives; results alter probability but not reaction severity.

IMF-058-01-0007-en	Why should anaphylaxis be treated without waiting for skin signs or laboratory confirmation?	It is a rapidly evolving reaction threatening airway, breathing or circulation, and skin or mucosal features are sometimes absent, so these signs after a likely trigger warrant immediate treatment.

IMF-058-01-0008-en	How should a patient with anaphylaxis be positioned, and why is sudden standing avoided?	Supine with legs elevated when tolerated, lateral in pregnancy and in the recovery position if unconscious, because sudden standing can precipitate collapse.

IMF-058-01-0009-en	Why do bronchodilators, antihistamines and corticosteroids not replace adrenaline in anaphylaxis?	A bronchodilator treats only persistent bronchospasm, antihistamines relieve only skin symptoms, and corticosteroids have no reliable immediate life-saving effect.

IMF-058-01-0010-en	What changes in refractory anaphylaxis, and why may glucagon be considered?	An experienced team gives monitored intravenous adrenaline infusion, further fluid and airway planning, and seeks alternative or additional shock; glucagon can be considered because beta blockade may blunt the response.

IMF-058-01-0011-en	Why is observation after anaphylaxis individualised, and what should discharge provide?	Biphasic symptoms can recur, so observation follows severity, treatment needed, comorbidity, trigger and access to help; discharge provides trigger referral, autoinjectors when indicated, technique and an action plan.

IMF-058-01-0012-en	Why is chronic spontaneous urticaria not usually pursued as a hidden food allergy, and how is it treated?	It is commonly autoimmune rather than an undiscovered food allergy; second-generation antihistamines are first-line and may be increased under guidance, and resistant disease can receive biologic therapy.

IMF-058-01-0013-en	What distinguishes bradykinin-mediated from histamine-mediated angioedema clinically and therapeutically?	Bradykinin-mediated angioedema from angiotensin-converting enzyme inhibitors or hereditary complement-regulator defects lacks urticaria and responds poorly to adrenaline or antihistamine, so airway protection and cause-specific inhibitors are used.

IMF-058-01-0014-en	Why do allergic rhinitis, asthma, eczema and food allergy cluster, and what is the limit of oral immunotherapy?	They share epithelial-barrier and type-two immune pathways; oral immunotherapy raises the reaction threshold for selected foods but is not risk-free permission for unrestricted intake.

IMF-058-01-0015-en	Which features suggest a primary immunodeficiency rather than ordinary infection susceptibility?	Unusually severe, recurrent, persistent, opportunistic or anatomically unusual infection, plus clues such as poor growth, deep abscesses, autoimmunity or live-vaccine reactions; common infections alone do not establish deficiency.

Integrated Medical Foundations; chapter 58, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: d758bc34da93f813abc9a45955092454ea800e62b7296dae96d43b70fa74e654; editorial review pending	imf lang::en chapter::058 module::058-02 review::pending
IMF-058-02-0003-en	Why can sudden sitting or standing be fatal during anaphylaxis?	With low venous return, an abrupt move to sitting or standing can precipitate empty-ventricle arrest, so the patient stays supine with legs elevated or in a supported position needed for breathing.

IMF-058-02-0004-en	How should a normal serum tryptase after suspected anaphylaxis be interpreted?	Tryptase supports mast-cell activation when sampled at appropriate acute and baseline times, but sensitivity varies by trigger, so a normal result does not exclude anaphylaxis.

IMF-058-02-0005-en	What infection patterns point to neutrophil defects, terminal-complement deficiency or absent spleen?	Neutrophil defects cause deep bacterial and fungal abscesses, impaired pus or unusual catalase-positive infection; terminal-complement deficiency predisposes to invasive Neisseria; asplenia impairs clearance of encapsulated organisms and red-cell parasites.

IMF-058-02-0006-en	Why should prophylaxis follow a patient's integrated immune state rather than one drug name?	Combinations alter several compartments at once: a patient on corticosteroid, B-cell depletion and chemotherapy may have T-cell dysfunction, poor antibody, neutropenia, mucosal injury and a central line together.

IMF-058-02-0007-en	Why should a patient without a functioning spleen who develops fever be assessed immediately rather than told to return if it persists?	Sepsis from encapsulated bacteria such as pneumococcus, meningococcus and Haemophilus influenzae progresses rapidly from mild prodromal symptoms, so antibiotics follow cultures without delay.

IMF-058-02-0008-en	Why can inflammation from an opportunistic infection worsen soon after antiretroviral therapy starts, and what does it usually signify?	Early immune recovery can unmask or worsen inflammation against an existing infection, an immune-reconstitution syndrome; it does not usually mean treatment failure, but timing and management vary by pathogen.

IMF-058-02-0009-en	What two problems can abrupt withdrawal of prolonged glucocorticoids cause at once, and what should the plan specify?	It can precipitate adrenal crisis even as the treated inflammatory disease relapses; the plan specifies taper, infection and bone prophylaxis, glucose monitoring and stress-dose considerations.

IMF-058-02-0010-en	What specific vulnerabilities do B-cell depletion, complement inhibition and Janus-kinase inhibition create?	B-cell depletion lowers new antibody responses and can cause prolonged hypogammaglobulinaemia or viral reactivation; complement inhibition raises meningococcal risk even after vaccination; Janus-kinase inhibition can increase zoster and thrombosis.

IMF-058-02-0011-en	Why must suspected checkpoint-inhibitor immune-related adverse events be distinguished from infection before immunosuppression?	Varied symptoms, sometimes lagging well behind a dose, can be immune-related events but also infection, tumour progression or drug toxicity, and immunosuppression given while an infection is missed is itself dangerous.	Integrated Medical Foundations; chapter 58, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: d758bc34da93f813abc9a45955092454ea800e62b7296dae96d43b70fa74e654; editorial review pending	imf lang::en chapter::058 module::058-02 review::pending
IMF-058-02-0012-en	Why are vaccines timed before immunosuppression, and why may inactive vaccine responses be rechecked?	Live vaccines may later be unsafe and need a sufficient interval before suppression starts; inactive vaccines cannot cause infection but responses may be inadequate, so repeat immunisation or antibody assessment is arranged.	Integrated Medical Foundations; chapter 58, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: d758bc34da93f813abc9a45955092454ea800e62b7296dae96d43b70fa74e654; editorial review pending	imf lang::en chapter::058 module::058-02 review::pending
IMF-058-02-0013-en	Why is empirically increasing immunosuppression for solid-organ graft dysfunction dangerous?	Thrombosis, obstruction, leak, recurrence, dehydration, calcineurin toxicity and infection can mimic rejection, so drug levels, imaging, microbiology, donor-specific antibodies and biopsy must first exclude infection.	Integrated Medical Foundations; chapter 58, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: d758bc34da93f813abc9a45955092454ea800e62b7296dae96d43b70fa74e654; editorial review pending	imf lang::en chapter::058 module::058-02 review::pending
IMF-058-02-0014-en	Why must a calcineurin-inhibitor trough level be interpreted in clinical context?	The window is narrow: too little risks rejection and too much causes renal vasoconstriction, hyperkalaemia and neurotoxicity, while interactions and diarrhoea shift levels, so timing, adherence and graft state matter.	Integrated Medical Foundations; chapter 58, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: d758bc34da93f813abc9a45955092454ea800e62b7296dae96d43b70fa74e654; editorial review pending	imf lang::en chapter::058 module::058-02 review::pending
IMF-059-01-0001-en	Why does the toxicological approach stabilise physiology before the poison is identified?	Histories are incomplete and products may be mixed, so staff are protected, exposure is stopped and airway, breathing, circulation, temperature, glucose and seizures are stabilised before toxidromes, tests and antidotes are pursued.

IMF-059-01-0002-en	How should a contaminated patient be handled before and during irrigation so that rescuers are not harmed?	Nobody enters contamination without protection; clothing is removed and dry chemicals brushed off before skin and eyes are irrigated generously, and inhalational cases are moved to fresh air without exposing rescuers.

IMF-059-01-0003-en	Why do normal early findings not exclude serious poisoning?	Delayed-release formulations, toxic metabolites and hepatic toxicity can declare themselves later, so a normal early assessment cannot rule them out.

IMF-059-01-0004-en	In deliberate self-poisoning, why should a report of low intent not lessen the medical response, and when is psychosocial assessment done?	Low intent does not reduce the dose taken, so the medical risk is judged on the exposure; psychosocial safety assessment follows stabilisation.

IMF-059-01-0005-en	Sympathomimetic and antimuscarinic toxicity both cause agitation and mydriasis. What distinguishes them?	Sympathomimetic toxicity causes sweating, whereas antimuscarinic toxicity gives dry flushed skin with reduced bowel sounds and urinary retention.

IMF-059-01-0006-en	How do serotonin toxicity and neuroleptic malignant syndrome differ in tempo, trigger and neuromuscular signs?	Serotonin toxicity shows hyperreflexia and clonus with mental change, autonomic activation and heat, while neuroleptic malignant syndrome evolves more slowly after dopamine blockade with rigidity.

IMF-059-01-0008-en	Why is a paracetamol concentration measured after possible overdose even when the patient has no symptoms?	Early paracetamol poisoning may cause only mild symptoms while a reactive metabolite injures the liver, so absent symptoms cannot exclude a toxic ingestion.

IMF-059-01-0009-en	What does each of QRS widening and QT prolongation signify on the electrocardiogram of a poisoned patient?	QRS widening suggests sodium-channel blockade, while QT prolongation increases the risk of polymorphic ventricular tachycardia.

IMF-059-01-0010-en	Why should management not be driven by a urine drug screen?	Screens give false results, have long detection windows and correlate poorly with impairment, so the clinician treats the patient, not the screen.

IMF-059-01-0011-en	Under what conditions is activated charcoal useful, and what limits its use?	It adsorbs many substances if given early to a cooperative patient with a protected airway; otherwise aspiration can be catastrophic, and it binds alcohols, metals, corrosives and some small ions poorly.

IMF-059-01-0012-en	When is whole-bowel irrigation considered, in contrast to gastric lavage and induced vomiting?	It is selected under specialist guidance for sustained-release drugs, substances charcoal does not bind, or body packing, whereas lavage is rarely appropriate and vomiting should not be induced.

IMF-059-01-0013-en	How does paracetamol overdose injure the liver, and how does N-acetylcysteine counter this?	Saturated conjugation lets a reactive metabolite deplete glutathione and injure liver; N-acetylcysteine replenishes glutathione, is highly effective early and remains useful after injury.

IMF-059-01-0015-en	Why can salicylate toxicity worsen while the serum concentration is falling?	The drug moves into tissues, so clinical toxicity can progress despite a falling serum level; salicylate concentrations are therefore interpreted serially.

IMF-059-01-0016-en	Why is naloxone titrated to adequate breathing, and why must patients still be observed afterwards?	Ventilation is the priority, so the target is breathing rather than painful withdrawal; naloxone may act for less time than the opioid, so recurrent toxicity needs observation or infusion.

IMF-059-02-0005-en	Why is the electrocardiogram an early toxicology test, and why is it repeated?	It reveals sodium-channel blockade, potassium-channel delay, bradyarrhythmia, ischaemia and conduction disease, and serial tracings are needed because absorption and metabolites evolve.

IMF-059-02-0006-en	Why is acidaemia dangerous in salicylate poisoning, and why must potassium be corrected during alkalinisation?	Acidaemia increases entry of non-ionised salicylate into brain, and urinary alkalinisation with sodium bicarbonate only works when potassium is corrected.

IMF-059-02-0007-en	Why is intubating a salicylate-poisoned patient hazardous, and what general principle does it illustrate?	Even brief apnoea or ordinary ventilator settings let carbon dioxide and acidity rise abruptly; a physiological adaptation that looks abnormal may be keeping the patient alive.

IMF-059-02-0008-en	In methanol or ethylene glycol poisoning, why is a normal osmolar gap late in the course not reassuring?	Both become toxic after alcohol-dehydrogenase metabolism; the osmolar gap may be high early and fall as the anion gap rises, so a late normal gap can accompany serious toxicity.

IMF-059-02-0010-en	What guides the decision to dialyse in lithium toxicity, and why is activated charcoal not relied on?	Dialysis rests on neurological features, kidney function, ingestion pattern and change over time, not concentration alone; activated charcoal does not adsorb lithium.

IMF-059-02-0011-en	Why may both ordinary pulse oximetry and a later carboxyhaemoglobin level underestimate carbon monoxide poisoning?	Ordinary pulse oximetry reads carboxyhaemoglobin as oxygenated, and a low level measured after oxygen or delay underestimates the peak burden.

IMF-059-02-0012-en	When do oximes help in organophosphate poisoning, and why is prolonged respiratory surveillance needed?	For selected compounds, oximes reactivate acetylcholinesterase before enzyme ageing; weakness can emerge after cholinergic symptoms improve, so breathing is watched for longer.

IMF-060-01-0001-en	Why can the same symptom carry a different differential diagnosis in different patients?	Exposure links the patient to environments, vectors, animals, water, chemicals, tasks and social conditions, so healthcare work, mining, farming, displacement, a long flight, freshwater contact or malaria-region travel each reshape it.

IMF-060-02-0006-en	When a workforce shows falling lung function or rising dermatitis, why investigate the process rather than individual lifestyle?	Surveillance exists to detect early change and control exposure, not to select people out as unfit; a normal individual test does not justify continued hazardous exposure.

IMF-061-02-0008-en	Why is abrupt involuntary discontinuation of long-term opioids dangerous, and what is preferred?	It can trigger withdrawal, illicit substitution, and suicide risk, so taper collaboratively unless immediate toxicity demands faster action, and offer agonist therapy for opioid-use disorder.

IMF-061-02-0009-en	How do vasoconstrictor and patient factors change the safe total dose of local anaesthetic?	Vasoconstrictor in suitable sites prolongs local exposure and reduces systemic absorption; the total of every infiltration and block is adjusted for weight, pregnancy, low cardiac output, liver dysfunction, acidosis, and protein binding.

IMF-061-02-0010-en	Why can a patient arrest immediately after an anatomically successful intubation?	Induction removes airway tone and sympathetic support and positive-pressure ventilation reduces venous return, so severe hypovolaemia, tamponade, tension pneumothorax, pulmonary hypertension, or metabolic acidosis can decompensate unless physiology is prepared.

IMF-061-02-0011-en	Why can neuromuscular paralysis conceal awareness during general anaesthesia?	Paralysis produces neither unconsciousness nor analgesia, so depth and drug delivery must be cross-checked, especially during low-dose emergency anaesthesia.

IMF-061-02-0012-en	Why is temperature an unreliable early sign of malignant hyperthermia, and what appears first?	This skeletal muscle calcium regulation crisis first shows an unexplained rapid carbon dioxide rise, tachycardia, rigidity, acidosis, and hyperkalaemia, while the temperature rise can be late.

IMF-061-02-0013-en	How does a high neuraxial block cause profound bradycardia and shock?	Sympathetic blockade causes vasodilation and reduced venous return, and a high block also impairs cardiac accelerator fibres, intercostal function, arms, and consciousness.

IMF-061-02-0014-en	Why is recovery after sedation a distinct high-risk phase?	Procedural stimulation ends while sedative absorption and active metabolites continue, so procedural success includes safe recovery, not only completing the intervention.

IMF-062-01-0001-en	Why must failing organs in critical illness be managed as an interacting system rather than one at a time?	Organ failures interact: ventilation alters circulation, shock injures kidney and brain, inflammation changes drug handling, and immobility weakens respiratory muscles.

IMF-062-01-0002-en	When recognising critical illness, what should weigh more than a single score, and what should begin immediately?	Trends and clinician concern matter more than one score; airway, breathing, circulation, disability, and exposure assessment begins while calling help and treating immediately reversible causes.

IMF-062-01-0003-en	Why should each form of monitoring in intensive care answer a specific question?	Lines, catheters, alarms, and blood draws themselves cause infection, thrombosis, anaemia, sleep disruption, and false intervention, so monitoring without a question adds harm.

IMF-062-01-0004-en	Why can a normal oxygen saturation fail to protect tissues in profound anaemia or low cardiac output?	Oxygen delivery is cardiac output times arterial oxygen content, and content is dominated by haemoglobin-bound oxygen, so saturation cannot offset too little haemoglobin or flow.

IMF-062-01-0005-en	Why is a raised lactate not a direct measure of inadequate oxygen delivery?	Besides sustained delivery imbalance, lactate also rises from adrenergic glycolysis, impaired clearance, drugs, seizure, and mitochondrial dysfunction.

IMF-062-01-0006-en	Why is oxygen titrated after the initial emergency rather than left at a high concentration?	Excess oxygen causes absorption atelectasis, oxidative injury, vasoconstriction, and hypercapnia in susceptible patients.

IMF-062-01-0007-en	How does heated high-flow nasal oxygen reduce the work of breathing?	It reduces dead-space rebreathing and provides modest distending pressure, which together decrease respiratory work.

IMF-062-01-0008-en	Why should pulse oximetry and arterial blood gas results both be read against the clinical trajectory?	Oximetry is distorted by perfusion, motion, skin pigmentation, dyshaemoglobins, nail products, and device limits; blood gas measures tensions and acid-base status but must be interpreted with the clinical course.

IMF-062-01-0009-en	What distinguishes continuous positive airway pressure from bilevel support in what each improves?	Continuous pressure recruits alveoli, improves oxygenation, and lowers left-ventricular afterload; bilevel support adds inspiratory assistance to improve ventilation.

IMF-062-01-0010-en	Why is a prolonged unsuccessful trial of non-invasive support harmful, and what signals failure?	It delays a definitive airway and increases harm; worsening acidosis, respiratory rate, oxygenation, effort, consciousness, or circulation signals failure.

IMF-062-01-0011-en	Which patient features make non-invasive respiratory support unsafe?	Inability to protect the airway, severe vomiting, a facial barrier, untreated pneumothorax, profound instability, or a need for immediate intubation.

IMF-062-01-0012-en	Why is intubation a physiological procedure, and why is hypotension corrected beforehand?	Positive pressure after intubation reduces venous return, so hypotension is corrected in anticipation; preparation also includes preoxygenation, position, suction, drugs, and backup airway.

IMF-062-01-0014-en	Which ventilator settings mainly control carbon dioxide and which support oxygenation, and does mode choice drive outcome?	Tidal volume and rate remove carbon dioxide; inspired oxygen and end-expiratory pressure support oxygenation. Outcome depends more on targets, synchrony, lung protection, and reassessment than mode name.

IMF-062-01-0015-en	Why is lung-protective tidal volume set from predicted rather than actual body weight?	Lung size follows height and sex-related anatomy rather than actual weight, so predicted weight matches tidal volume to the lung being ventilated.

IMF-062-01-0016-en	What limits the level of positive end-expiratory pressure used to prevent ventilator-induced lung injury?	Enough pressure is used to prevent alveolar collapse and repeated opening, but not so much that it causes unacceptable overdistension or haemodynamic compromise.

IMF-062-01-0019-en	Why should the cause of agitation or poor ventilator synchrony be treated before sedation is escalated?	It may reflect pain, fear, delirium, tube discomfort, secretions, bronchospasm, acidosis, settings, or neurological injury; analgesia-first light sedation shortens ventilation and delirium.

IMF-062-01-0021-en	Why is a fluid challenge given with a defined dose, response, and stopping rule rather than guided by central venous pressure?	Static central venous pressure poorly predicts fluid responsiveness, and unnecessary fluid causes oedema, impaired gas exchange, raised abdominal pressure, and delayed recovery.

IMF-062-01-0022-en	What distinguishes the role of norepinephrine from that of an inotrope in shock?	Norepinephrine raises vascular tone in distributive shock with less tachycardia; inotropes raise contractility when low output persists despite adequate pressure and volume, at arrhythmia and oxygen-demand cost.

IMF-062-01-0024-en	Which factors worsen raised intracranial pressure, and what is the proper role of brief hyperventilation?	Hypoxia, hypotension, fever, seizure, venous obstruction, and extreme carbon dioxide worsen it; brief hyperventilation is only a rescue bridge for impending herniation, not routine therapy.

The lung is heterogeneous, with dependent regions collapsed and small remaining regions taking most tidal volume; proning redistributes stress and improves dorsal recruitment and perfusion matching.

IMF-062-02-0010-en	Why is patient-ventilator dyssynchrony not by itself an indication for deeper sedation?	It is a sign of pain, anxiety, acidosis, secretions, auto-positive end-expiratory pressure, or poorly matched trigger or cycling, which waveforms reveal and should be corrected first.

IMF-062-02-0011-en	Why does fluid responsiveness not automatically mean that fluid should be given?	Fluid may not benefit when the circulation is already adequate, or when the lungs and right heart cannot tolerate it.

IMF-062-02-0012-en	Why is excessive fluid harmful in right-heart failure?	It dilates the right ventricle and shifts the septum, reducing left-ventricular filling and worsening coronary perfusion; afterload, rhythm, oxygenation, and cause are treated instead.

IMF-062-02-0013-en	Why can abrupt reduction of sedatives and opioids given for several days be mistaken for delirium or sepsis?	Iatrogenic withdrawal causes tachycardia, hypertension, sweating, agitation, diarrhoea, and insomnia; doses are reduced stepwise by cumulative exposure and half-life.

IMF-062-02-0014-en	Why do fever and a new opacity alone not establish ventilator-associated pneumonia?	Atelectasis, pulmonary oedema, pulmonary embolism, and drug fever can produce the same picture, so an adequate lower respiratory tract specimen is obtained.

IMF-063-01-0001-en	Why are fever, collapse, dizziness, and weakness approached by stabilising first and revising probability over time rather than by naming a diagnosis?	They are undifferentiated symptoms, not diagnoses, and can arise from benign self-limited illness or time-critical failure of circulation, respiration, brain, metabolism, or host defence.

IMF-063-01-0003-en	After a transient illness, why does a normal set of observations not prove safety, and what must be established instead?	The observations reflect only the present moment; the clinician must establish what happened before arrival, whether recovery is complete, baseline function, and recurrence risk.

IMF-063-01-0004-en	What distinguishes fever from hyperthermia, and how does this predict the response to antipyretics?	Fever is a regulated rise in hypothalamic set point driven by inflammatory mediators; hyperthermia is unregulated heat accumulation, so it does not respond to antipyretics.

IMF-063-01-0005-en	A febrile patient reports chills. What does this suggest, and what does it not establish?	Chills suggest that temperature is rising rapidly, but they do not necessarily mean bacteraemia.

IMF-063-01-0006-en	Why can the absence of high fever not exclude serious infection in some patients, and which patients?	Older, frail, pregnant, immune-suppressed, or medication-treated patients may have serious infection without mounting a high fever.

IMF-063-01-0007-en	In suspected sepsis, how should obtaining cultures be balanced against starting antibiotics?	Suitable cultures are obtained without delaying antibiotics, because sepsis is life-threatening organ dysfunction from a dysregulated response to infection.

IMF-063-01-0008-en	Why do hyperthermia syndromes such as serotonin toxicity or malignant hyperthermia require rapid cooling and mechanism-specific treatment?	Heat accumulates without a regulated set point, so antipyretics do not work; cooling and treatment directed at the specific mechanism are urgent.

IMF-063-01-0009-en	Why should persistent undiagnosed fever prompt reassessment rather than automatic broadening of antibiotics?	The cause may be hidden infection, inflammatory disease, cancer, medication, or an exposure; time course and repeated targeted testing outperform enormous one-time panels.

IMF-063-01-0010-en	What distinguishes syncope from presyncope, and what is the mechanism of syncope?	Syncope is transient global cerebral hypoperfusion causing loss of consciousness with rapid onset, brief duration, and spontaneous complete recovery; presyncope has similar warning without full loss.	Integrated Medical Foundations; chapter 63, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 07f7b70ae8a4ca92a6caf9ee0fb22c5a38e976602809e19ddc06a61fa1d132fa; editorial review pending	imf lang::en chapter::063 module::063-01 review::pending
IMF-063-01-0011-en	How do the triggers and mechanism of reflex syncope differ from those of orthostatic syncope?	Reflex syncope follows pain, fear, heat, prolonged standing, or visceral triggers; orthostatic syncope reflects inadequate vascular compensation to standing from volume loss, medicines, autonomic failure, or deconditioning.

IMF-063-01-0012-en	What are the limits of a supine-then-standing pressure measurement in explaining collapse?	A pressure drop can be asymptomatic, and an initially normal test does not exclude intermittent disease.

IMF-063-01-0013-en	Which features of a collapse raise the risk that it is cardiac syncope?	Exertional or supine collapse, sudden onset without prodrome, palpitations, an abnormal electrocardiogram, structural disease, family sudden death, or injury.

IMF-063-01-0014-en	Why must cardiac monitoring duration be matched to event frequency?	A normal short tracing does not exclude a rare dysrhythmia, so monitoring must last long enough to capture an event.

IMF-063-01-0015-en	Which features favour seizure over syncope, and why do brief jerks not settle the question?	Stereotyped aura, tonic then clonic movement, lateral tongue injury, prolonged post-event confusion, or focal deficit suggest seizure, but brief jerks also occur in syncope.

IMF-063-01-0016-en	How should psychogenic non-epileptic events be diagnosed, and why?	They are genuine functional episodes, so they require a positive neurological diagnosis rather than dismissal.

IMF-063-01-0017-en	Why is dizziness classified by timing and triggers rather than by the patient's descriptive words?	Words such as dizzy, light-headed, spinning, and off-balance are used inconsistently, whereas episodic triggered, spontaneous episodic, and continuous acute patterns guide the differential.	Integrated Medical Foundations; chapter 63, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 07f7b70ae8a4ca92a6caf9ee0fb22c5a38e976602809e19ddc06a61fa1d132fa; editorial review pending	imf lang::en chapter::063 module::063-01 review::pending
IMF-063-01-0018-en	When is head-impulse, nystagmus, and skew testing valid for identifying a central cause of vertigo?	Only in continuous acute vestibular syndrome with spontaneous nystagmus and in trained hands; it is invalid for brief episodic symptoms and unsafe without expertise.

IMF-063-01-0019-en	Why can early imaging not rule out posterior-circulation stroke in acute vertigo?	Early computed tomography poorly excludes posterior fossa ischaemia, and magnetic resonance can also be falsely negative early.

IMF-063-01-0021-en	In Guillain-Barre syndrome, why is forced vital capacity measured serially rather than relying on oxygen saturation?	Oxygen saturation falls late in pure ventilatory weakness, so it cannot give early warning of respiratory failure.

IMF-063-01-0022-en	How does the pattern of weakness distinguish myasthenia gravis from botulism?	Myasthenia gravis causes fluctuating ocular, bulbar, neck, or limb weakness with preserved sensation, whereas botulism causes descending paralysis with autonomic and pupil features.

IMF-063-01-0023-en	Why can a normal troponin, a negative early scan, or one normal observation not close a dangerous differential?	Results must be interpreted with pretest probability, and a test taken at the wrong time or once can be falsely reassuring.

IMF-063-01-0024-en	Why is observation described as an active diagnostic strategy rather than simply waiting?	It has a specified duration, repeat observations, examination, testing, oral intake, mobility, and escalation thresholds, so change is detected and acted upon.

IMF-063-02-0001-en	How does translating a vague label such as "collapse" or "weakness" make undifferentiated illness tractable?	Each label can mean several different failed functions, such as syncope, seizure, fall, or fatigue; converting it into a failed function and a timeline defines what must be explained.

IMF-063-02-0002-en	Why should the lowest or most abnormal pre-intervention state be recorded when reliable?	Oxygen, prehospital fluid, antipyretic, naloxone, or spontaneous recovery can normalise the numbers without removing the cause.

IMF-063-02-0003-en	How is compensated shock recognised when blood pressure is normal, and why is heart rate unreliable in some patients?	Integrate tachycardia, narrow pulse pressure, cold sweat, delayed capillary refill, restlessness, oliguria, lactate trend, and orthostatic symptoms; beta-blockers or a pacemaker prevent tachycardia.

IMF-063-02-0004-en	Why does a patient feel a chill while fever is rising, and what happens when the set point falls?	Cytokines raise the hypothalamic set point, so vasoconstriction and shivering raise core temperature and create the chill; when the set point falls, vasodilation and sweating occur.

IMF-063-02-0005-en	Why should blood cultures and empirical antibiotics be used proportionately rather than reflexively?	Contaminated or low-volume cultures create harm, so cultures suit sepsis, endocarditis, and selected focal syndromes; antibiotics match infection probability and consequence of delay, with daily reassessment.

IMF-063-02-0006-en	Why may syncope in an older person be reported as a simple fall, and which clues suggest it?	There may be no memory of the moment before the faint; facial or occipital injury and absence of a protective reaction are useful clues.

IMF-063-02-0007-en	On standing, how does the heart-rate response to a fall in pressure point to the mechanism?	A fall with appropriate tachycardia suggests volume loss or venous pooling; a disproportionately small heart-rate response suggests autonomic failure or rate-limiting medication.

IMF-063-02-0009-en	How do upper and lower motor-neuron weakness differ on examination?	Upper motor-neuron disease gives a pyramidal pattern, brisk reflexes, and pathological plantar response; lower motor-neuron disease gives reduced tone, atrophy, fasciculation, and depressed reflexes.

IMF-063-02-0011-en	Why is suspected adrenal crisis treated before definitive cortisol results?	It causes weakness, vomiting, hypotension, sodium and potassium change, and hypoglycaemia, which cannot wait for confirmation.

IMF-063-02-0012-en	Why must the expected result be predicted before a fluid trial or other observation manoeuvre is interpreted?	Responses are often nonspecific: symptom improvement after fluid, fever settling after antipyretic, or no recurrence during a short stay can mislead without a prior prediction.

IMF-063-02-0013-en	Why is each pending culture, re-reported image, or prolonged monitor result assigned a responsible person and contact deadline?	So that responsibility for an abnormal result is not transferred to the patient alone; a safety net is not a vague advice to return if worse.

IMF-063-02-0014-en	Why is calibrated diagnostic uncertainty safer than false precision?	False precision converts fever, dizziness, collapse, or weakness into a premature label that stops observation before physiology declares itself.

IMF-064-01-0001-en	Why should a test be ordered only when its result would change action?	A test changes uncertainty but does not replace reasoning, and it carries harms such as pain, anaemia, radiation, contrast injury, incidental findings, cascades and delay.

IMF-064-01-0002-en	Why can the same test have different predictive values in different settings?	Predictive values vary with prevalence, so the meaning of a positive or negative result depends on how common the target condition is in the population tested.

IMF-064-01-0004-en	Why can action be justified at a lower probability for some diseases than for others?	Thresholds reflect consequences: a dangerous but treatable disease justifies acting at a lower probability because missing it costs more.

IMF-064-01-0005-en	Why do healthy people fall outside reference intervals, and why does ordering more tests make abnormal results more likely?	Reference intervals commonly contain ninety-five per cent of a selected healthy population, so some healthy values lie outside, and each extra test adds another chance abnormality.

IMF-064-01-0006-en	How can specimen handling produce misleading potassium, glucose or coagulation results?	Haemolysis raises potassium and enzymes, delay changes glucose and blood gases, and an underfilled citrate tube distorts coagulation tests.

IMF-064-01-0008-en	Why can mean cell volume be normal in a patient with nutritional anaemia?	Mean cell volume classifies anaemia only broadly, and mixed deficiencies can combine to give an apparently normal value.

IMF-064-01-0010-en	Why does serum sodium need volume state and osmolality to be interpreted?	Sodium mainly reflects water balance rather than body sodium content, so volume state, glucose, osmolality and urine studies are needed to explain it.

IMF-064-01-0012-en	Why can creatinine misrepresent filtration early in acute kidney injury?	Creatinine reflects filtration imperfectly and lags acute injury, and it also varies with muscle, diet, secretion, age and drugs.

IMF-064-01-0013-en	Why can a normal osmolar gap or anion gap not exclude dangerous poisoning?	The osmolar gap varies with timing and other solutes and the anion gap needs albumin and baseline context, so neither can independently exclude poisoning.

IMF-065-01-0001-en	Why does population health look beyond treatment to explain why illness occurs unevenly?	Because housing, income, education, food, work, discrimination, environment, commercial influence, and access determine who becomes ill and who recovers.

IMF-065-01-0002-en	Why can a chronic survivable condition have high prevalence despite only modest incidence?	Prevalence depends on both incidence and duration, so a condition people live with for a long time accumulates existing cases even when new cases are modest.

IMF-065-01-0003-en	What distinguishes a rate from a risk, and why does the difference matter when follow-up is unequal?	Risk is a probability over a defined period, whereas a rate incorporates person-time, so it remains usable when people are followed for different lengths of time.

IMF-065-01-0004-en	Why can a large relative effect on an outcome still produce only a small absolute benefit?	If the outcome is rare, a large ratio change corresponds to few additional or prevented events, which is what the absolute risk difference expresses.

IMF-065-01-0005-en	How is the number needed to treat derived, and why must time horizon and baseline risk accompany it?	It is the reciprocal of the absolute risk reduction over the study period, so its value is meaningful only with the time horizon and baseline risk it came from.

IMF-065-01-0006-en	Why are crude comparisons between populations unreliable, and what limits the fix?	Age, sex, and other population structures distort crude comparisons; stratification or standardisation allows fairer comparison but depends on the chosen reference.

IMF-065-01-0007-en	Why can ecological data not show that a relationship applies to individuals?	Ecological data describe groups, so a relationship seen at group level cannot establish that the same relationship holds for the individuals within them.

IMF-065-01-0008-en	What distinguishes primordial prevention from primary prevention?	Primordial prevention stops risk emerging through housing, clean air, education, food policy, and regulation; primary prevention stops disease before onset through measures such as vaccination and blood-pressure management.

IMF-065-01-0009-en	Why do upstream interventions such as safe water often reach more people than counselling?	They change exposure for everyone without requiring repeated individual choice, although measures such as taxes should avoid placing regressive burdens on low-income people.

IMF-065-01-0010-en	Why is finding abnormalities not by itself a justification for screening?	Screening aims to reduce future morbidity or mortality, so it is worthwhile only when effective earlier treatment, a defined pathway, and a favourable balance of benefit, harm, and cost exist.

IMF-065-01-0011-en	Why can false positives outnumber true positives in screening even when the test is good?	When disease prevalence is low, the few true cases are outnumbered by false positives arising among the many unaffected people tested.

IMF-065-01-0012-en	How do length bias and lead-time bias flatter screening, and what evidence avoids them?	Length bias preferentially detects slow disease and lead-time bias lengthens survival only because diagnosis starts earlier, so randomised mortality or meaningful morbidity outcomes outweigh stage shift.

IMF-065-01-0013-en	Why does screening often favour sensitivity and then add a separate confirmatory test?	Choosing sensitivity avoids missed disease, and a specific confirmatory test follows because sensitivity and specificity trade off as the threshold changes.

IMF-065-01-0014-en	How can a screening programme that improves average outcomes still widen inequity?	If access is hardest for the people at greatest risk, the gains concentrate among those at lower risk while the highest-risk groups are left behind.

IMF-065-01-0015-en	How do conjugation, adjuvants, and boosters each strengthen vaccine protection?	Conjugation recruits T-cell help against polysaccharides, adjuvants enhance innate signalling, and boosters restore or broaden protection that has waned.

IMF-065-01-0016-en	Why is there no fixed herd-protection threshold for a vaccine?	Herd effects arise from interrupting spread, and that depends on transmissibility, clustering, waning, and vaccine performance, which all vary.

IMF-065-01-0017-en	An illness follows vaccination. Why does this not establish that the vaccine caused it, and how is it assessed?	Events after vaccination are not necessarily caused by it; assessment compares background rates, timing, mechanism, and controlled evidence.

IMF-065-01-0018-en	Why are live vaccines generally avoided in severe immune suppression, and how do inactivated vaccines differ?	Live vaccines can replicate, whereas inactivated vaccines cannot cause the target infection but may give weaker responses, so indicated vaccines are given before immune-suppressive treatment when feasible.

IMF-065-01-0019-en	Why is absolute cardiovascular risk estimated rather than treating each risk-factor number in isolation?	Risk factors such as smoking, pressure, lipids, diabetes, and age act together, so only their combined effect reflects a person's actual cardiovascular risk.

IMF-065-01-0020-en	Why is antiplatelet therapy valuable after established atherosclerotic disease but often not in low-risk primary prevention?	In low-risk primary prevention bleeding often outweighs the small benefit, whereas after established disease the benefit is substantial.

IMF-065-02-0002-en	How do direct and indirect standardisation differ, and why is a standardised estimate not the local burden?	Direct applies stratum-specific rates to a common reference population; indirect compares observed with expected events. Both yield comparative values that vary with the chosen standard.

IMF-066-01-0002-en	Why does good interpretation examine methods before results, and what distinction must it keep?	Methods decide whether results can be trusted at all, and absence of evidence must be distinguished from evidence of no effect.

IMF-066-01-0003-en	How does the structure of a focused question differ between treatment and diagnosis, and why does vagueness matter?	Treatment questions define population, intervention, comparator, and outcomes; diagnostic questions define target condition, test, reference standard, and setting. A vague question encourages selective evidence and irrelevant endpoints.

IMF-066-01-0005-en	What evidence is required to validate a surrogate outcome?	Evidence that changing the surrogate reliably changes the clinical outcome across the relevant mechanisms, not merely that the two are associated.

IMF-066-01-0006-en	How do randomisation, concealed allocation, and blinding each protect a trial?	Randomisation balances known and unknown prognostic factors on average, concealment prevents prediction of assignment before enrolment, and blinding reduces differential care, reporting, and assessment.

IMF-066-01-0007-en	What distinguishes intention-to-treat from per-protocol analysis in what each estimates and risks?	Intention-to-treat analyses assigned groups, preserving randomisation and estimating a treatment strategy under real adherence; per-protocol estimates effects in adherent participants but loses randomisation and is vulnerable to selection.

IMF-066-01-0008-en	Why must cluster trials account for within-cluster similarity, and when do crossover trials suit?	Cluster trials randomise groups whose members resemble each other, so this similarity must be modelled; crossover trials suit stable conditions without carryover.

IMF-066-01-0010-en	Why can meta-analysis precisely estimate the wrong thing?	Combining studies increases precision but does not correct biased inputs, and pooling incomparable studies yields a precise estimate of the wrong construct.

IMF-066-01-0011-en	What does a ninety-five per cent confidence interval mean under repeated sampling, and what common reading is only shorthand?	Across repeated identical studies, ninety-five per cent of such intervals would contain the true parameter; it is not strictly the probability that this one interval contains the truth.

IMF-066-01-0012-en	What does a p value not tell you, and why does statistical significance depend on study size?	It is not the probability the null is true, that results arose by chance, or the size and importance of an effect; large studies detect trivial differences while small studies can miss important ones.

IMF-066-01-0014-en	Why do non-inferiority and equivalence trials need prespecified margins, adequate adherence, and careful analysis?	Non-significance does not establish equivalence, and bias toward no difference can falsely support a claim of success.

IMF-066-01-0015-en	How do selection, performance, detection, and attrition bias differ in where they arise?	Selection bias comes from inclusion or retention creating prognostically different groups, performance bias from unequal co-interventions or attention, detection bias from differing outcome measurement, and attrition bias from missing outcomes related to treatment and prognosis.

IMF-066-01-0017-en	How does confounding create a non-causal association, and why can adjustment itself introduce bias?	A third factor predicts exposure and independently affects outcome; adjusting for a variable caused by exposure, a mediator, or a collider can create bias, and unmeasured confounding is never guaranteed removed.

IMF-066-01-0018-en	Why does triangulation across study designs strengthen causal inference when trials are not possible?	Designs with different biases are unlikely to be misled in the same way, so agreement among them is more convincing than any single design.

IMF-066-01-0019-en	How do reverse causation and immortal-time bias distort apparent exposure effects?	In reverse causation, early disease changes the apparent risk factor; immortal-time bias grants exposed patients a period in which the outcome could not occur, flattering exposure.

IMF-066-01-0021-en	What does the area under a receiver-operating-characteristic curve fail to measure, and why can a discriminating test add little?	It measures discrimination but not calibration, utility, or outcomes, and a discriminating test adds little if management does not change.

IMF-066-01-0022-en	Why is a hazard ratio not a risk ratio, and why does ignoring competing events overestimate incidence?	A hazard ratio compares instantaneous rates under proportional hazards; competing events such as death before fracture prevent the outcome, so ignoring them inflates its estimated incidence.

IMF-066-01-0023-en	Why can spontaneous reports detect drug-safety signals but not determine incidence, and what is channeling bias?	Reporting and the denominator are unknown, so frequency cannot be calculated; channeling bias arises when high-risk patients preferentially receive one treatment.

IMF-066-01-0024-en	Why does significance in one subgroup and non-significance in another not prove a difference, and how is certainty distinct from benefit?	Only a statistically tested interaction supports a difference, and data-driven subgroups often yield chance findings; high certainty does not mean large benefit, nor low certainty no benefit.

IMF-066-02-0001-en	Which four questions does evidence-based practice separate, and why can a prestigious label answer none of them alone?	Validity, magnitude and uncertainty, applicability, and worth to this patient; a journal, randomised label, small p value, or guideline does not by itself establish any of these.

IMF-066-02-0002-en	Why can stopping a trial early mislead, and what is checked in the registry and protocol?	Early stopping can lock in a large chance effect; the primary outcome, analysis plan, intended sample size, and follow-up are checked for changes made after results were seen.

IMF-066-02-0003-en	Why is a baseline significance test not the answer to imbalance in a small randomised trial?	Randomisation does not guarantee balance in small trials; what matters is whether imbalances are clinically important and whether adjusted analysis was prespecified.

IMF-066-02-0005-en	How does adjusting for a mediator differ in consequence from conditioning on a collider?	Adjusting for a mediator on the causal path removes part of the effect of interest, while conditioning on a collider caused by two variables creates a false association between them.

IMF-066-02-0008-en	Why does non-adherence threaten a non-inferiority trial, and how is this guarded against?	Non-adherence biases toward apparent similarity, so the trial needs a clinically justified margin, reliable active control, preserved conduct, and scrutiny by both intention-to-treat and per-protocol analysis.

IMF-067-01-0003-en	Why is a signed form not sufficient evidence of valid consent?	Consent is a process, not a signature: it is valid only if voluntary, informed, given by a person with capacity, and specific enough for the proposed intervention.

IMF-067-01-0004-en	Which two perspectives together determine whether a risk is material and must be disclosed?	What a reasonable person in the patient's position would consider significant, and what this particular patient is likely to value.

IMF-067-01-0005-en	What conditions must all be met for emergency necessity to permit treatment, and what does it not authorise?	The person lacks capacity, no valid refusal applies, delay risks serious harm, and treatment is proportionate to presumed wishes and interests; it does not authorise convenient non-urgent care.

IMF-067-01-0006-en	How much room does therapeutic privilege give a clinician to withhold information because it may distress the patient?	Very little: it is extremely narrow, and matters such as unexpected findings, trainee participation, intimate examination or research may require explicit discussion.

IMF-067-01-0007-en	Which four abilities does decision-making capacity require, and why must it be assessed for each decision?	Understanding, retaining, using or weighing, and communicating; because capacity is decision- and time-specific, it may be present for a simple choice but absent for a complex high-risk one.

IMF-067-01-0008-en	Why does a mental illness or an unwise choice not by itself establish incapacity?	Capacity depends on the functional abilities for the decision, and a person's values can differ from the clinician's without being irrational.

IMF-067-01-0009-en	What should a clinician do to support capacity before concluding that it is absent?	Treat pain, delirium, hypoxia, withdrawal, fear and sensory barriers, and use interpreters, accessible formats, trusted supporters and optimal timing.

IMF-067-01-0010-en	What distinguishes substituted judgement from the best-interests standard?	Substituted judgement asks what the patient would choose; best interests integrates welfare, values, relationships, least restriction and previously expressed wishes.

IMF-067-01-0011-en	What limits parental authority over a young child's care, and how should a harmful parental refusal be handled?	Parental authority is limited by the child's welfare; if refusal exposes the child to serious preventable harm, escalate through safeguarding, institutional and legal pathways rather than abandoning care.

IMF-067-01-0012-en	Why should confidential adolescent care be offered while its limits are explained?	Confidentiality encourages adolescents to disclose, but serious safety risk and safeguarding concerns may require action, so the limits must be made clear.

IMF-067-01-0013-en	When disclosure without consent is justified, how should it be carried out?	Share the minimum necessary information, tell the patient when safe and lawful, consult senior or legal support, and document the authority and reasoning.

IMF-067-01-0014-en	How should the familial implications of genetic information be managed?	Encourage patient-led sharing and specialist counselling; exceptional disclosure to relatives is considered only when serious preventable harm is likely and legal and ethical criteria are met.

IMF-067-01-0015-en	Why must errors in the clinical record be corrected by dated, traceable amendments?	The record is both a care tool and a legal document, so it must stay accurate and transparent rather than silently altered, and copying inaccurate text propagates harm.

IMF-067-01-0016-en	Why do professional boundaries still matter after a patient's care has ended?	Power persists after care ends, so sexual or financial relationships and dual relationships can still exploit the patient and impair judgement.

IMF-067-01-0017-en	An injury is inconsistent with the history given. Why is this not enough to conclude abuse?	Warning signs such as inconsistent injury, delayed care or a controlling companion are indicators only; none proves abuse alone, so they prompt private assessment.

IMF-067-01-0019-en	Why should a competent adult experiencing intimate-partner violence not be forced to leave?	Abrupt intervention without planning can increase danger, so clinicians offer care, shelter, advocacy, police options and safety planning unless law requires action.

IMF-067-01-0021-en	Why is a poor outcome alone not negligence?	Negligence generally requires a duty, breach of the standard, causation and compensable harm; a bad result without breach and causation does not meet this.

IMF-067-01-0022-en	What criteria should guide allocation of scarce resources, and what must be excluded?	Transparent, consistent clinical criteria, not social worth, wealth, influence, disability stereotypes or inequitable first-come rules, because disability is not lower life value.

IMF-067-01-0023-en	Why can a restrictive public-health measure backfire even when it is legal?	Such measures also require necessity, proportionality, least restriction, reciprocity and review, and coercion without accessible services or support damages trust.

IMF-067-02-0001-en	Why does separating facts, values and process help in an ethically difficult case, and is an uncomfortable outcome necessarily unethical?	It clarifies options, conflicting values and legitimate authority so a fair process can be chosen; an uncomfortable outcome may reflect unavoidable loss rather than misconduct.

IMF-067-02-0002-en	What does supported decision-making aim to do before substitution, and what limit applies to a trusted supporter?	It strengthens the person's own agency before another decision-maker is substituted; a supporter may help communication but must not quietly replace the patient's voice.

IMF-067-02-0003-en	Why can a familiar-sounding answer fail a capacity assessment while a choice based on unusual beliefs passes?	Capacity depends on genuine weighing: delirium can prevent weighing behind a plausible answer, whereas unusual religious or personal beliefs may still be capacitous.

IMF-067-02-0004-en	When capacity is absent, whose values should the substitute apply, and how is disagreement among relatives resolved?	The patient's known values and prior wishes, not the substitute's preference; relatives' disagreement is not a vote, so clarify legal roles, seek consensus and escalate unresolved high-stakes conflict.

IMF-067-02-0006-en	What distinguishes a legitimate recommendation from manipulation that undermines voluntariness?	Recommending is appropriate, but presenting only the favoured option, exaggerating certainty or describing refusal as abandonment constrains the patient's choice.

IMF-067-02-0007-en	Why does labelling chemical restraint as sedation not remove the need for safeguards?	Chemical restraint is medication used mainly to control behaviour rather than treat an underlying syndrome, so it still requires safeguards, monitoring and review.

IMF-068-01-0006-en	Why should prognosis be described as scenarios rather than a date?	Prognosis is a range, so best, worst, and likely scenarios with broad time frames convey it, with uncertainty stated.

IMF-068-01-0007-en	What does conflict over treatment often reflect, and how should the team respond?	It often reflects differences in facts, values, grief, or trust; name shared goals, summarise disagreement, and seek second opinion or palliative, ethics, or mediation support.

IMF-068-01-0009-en	Why may preventive drugs be stopped in palliative care, and what must simplification avoid?	Their delayed benefit may no longer match prognosis; stopping must avoid withdrawal from corticosteroids, benzodiazepines, anticonvulsants, opioids, and other dependence-producing therapy.

IMF-068-01-0010-en	Why identify the type of pain rather than relying on opioids alone?	Specific pains may respond to targeted treatment such as corticosteroids, bisphosphonates, radiotherapy, or nerve blocks; opioids are central for severe pain but not the only treatment.

IMF-068-01-0012-en	Why is the calculated dose reduced when converting from one opioid to another?	Conversion tables are only estimates and cross-tolerance is incomplete, so the dose is reduced and specialist advice sought.

IMF-068-02-0001-en	Which questions should precede investigating or treating a new problem in advanced illness, and why?	Ask the likely mechanism, reversible contributors, burden of clarification, time available for benefit, and how results would change management; this prevents both neglect and reflex intervention.

IMF-068-02-0002-en	Why can a single numerical symptom score not replace narrative assessment?	Suffering has interacting dimensions, as when breathlessness causes panic that intensifies breathlessness, so a score tracks change but not meaning, coping, or fears.

IMF-068-02-0004-en	What does repeated use of rescue opioid doses suggest, and why is escalation alone a mistake?	Uncontrolled background pain, predictable incident pain needing anticipatory dosing, or a new cause; escalation without reassessment fails to treat the true mechanism.

IMF-068-02-0012-en	Why are the final days recognised from trajectory and repeated assessment rather than a single sign?	Signs such as bedbound state and minimal intake raise probability only collectively, and reversible sedation, infection, hypercalcaemia, or drug toxicity can mimic dying.

IMF-070-01-0005-en	How does adrenarche relate to the central onset of puberty?	Puberty begins when hypothalamic gonadotropin-releasing hormone pulsatility reactivates, driving gonadotropin and gonadal steroid production; adrenarche is partly independent and produces pubic or axillary hair and body odour.

IMF-070-01-0008-en	Why can persistent asymmetry, abnormal tone, or early hand preference indicate neurological disease?	Motor development depends on the central and peripheral nervous systems, with cortical control gradually inhibiting primitive reflexes, so these signs may reflect disease in that pathway.

IMF-070-01-0009-en	Why is hearing assessment essential in speech delay even when caregivers believe hearing is normal?	Language development requires hearing alongside social interaction, cognition, motor planning, and exposure to comprehensible language, so hearing must be assessed rather than assumed.

IMF-070-01-0010-en	Why is bilingualism not itself a cause of language delay, and which features do change the differential?	Bilingual children distribute vocabulary across languages and are not inherently delayed; loss of language, absent social reciprocity, poor response to sound, or failure to use gesture change the differential.

IMF-070-01-0011-en	Why should no single behaviour be taken as proof of a specific family circumstance?	Behaviour is shaped by normal temperament as well as deprivation, inconsistent safety, caregiver mental illness, trauma, and neurodevelopmental differences, so one behaviour cannot identify its cause.

IMF-070-01-0012-en	How does the developmental timing of adolescent reward sensitivity explain risk-taking, and what does it not justify?	Reward sensitivity and social salience develop earlier than full regulatory control, favouring exploration and risk-taking; this is not an incapacity to reason or grounds to exclude adolescents from decisions.

IMF-070-01-0013-en	What distinguishes developmental delay, intellectual disability, and a specific developmental disorder?

IMF-070-01-0014-en	Why is regression always important, and what should be clarified when it is reported?

IMF-070-01-0016-en	Why should an autism diagnosis map strengths and needs, and why must it not be used to explain every symptom?	Presentation varies with language, cognition, sex, culture, compensatory strategies, and support, so diagnosis should not reduce a person to deficits, and other behavioural or medical symptoms still need their own explanation.

IMF-070-01-0018-en	Why can infants decompensate quickly with airway illness, and what does bradycardia signify in a sick infant?	High oxygen demand, compliant chest walls, small airways, and limited reserve mean a small loss of radius sharply raises resistance and work causes fatigue; bradycardia often reflects hypoxia and is a pre-arrest sign.

IMF-070-01-0019-en	Why are infants prone both to rapid dehydration and to hyponatraemia from excess hypotonic fluid?	They have a higher body water proportion, immature renal concentrating ability, and rapid fluid turnover, so losses dehydrate them quickly while excessive hypotonic fluid can lower sodium.

IMF-070-01-0020-en	Why is neonatal hypothermia a concern beyond exposure, and why are neonates prone to hypoglycaemia?	Large surface area, limited insulation, and immature control make thermoregulation inefficient, and hypothermia can signal sepsis; limited glycogen stores allow hypoglycaemia during illness or feeding difficulty.

IMF-070-01-0021-en	Why is fever height a poor guide to bacterial infection, particularly in very young infants?	Height alone does not separate bacterial from viral disease; risk depends on age, appearance, immune status, focal signs, and physiology, and very young infants may have invasive infection with low or normal temperature.

IMF-070-02-0012-en	Why can ferritin mislead in suspected iron deficiency, and what else is used?	Ferritin rises during inflammation, and microcytosis also occurs with thalassaemia and inflammation, so transferrin saturation, inflammatory markers, blood film, and haemoglobin studies may be needed.

IMF-070-02-0013-en	Why is unconjugated neonatal bilirubin dangerous, and why does conjugated jaundice always need evaluation?	Unconjugated bilirubin can cross the immature blood-brain barrier and injure the brain at risk-dependent concentrations; conjugated jaundice is never physiological and may reflect biliary obstruction.

IMF-070-02-0014-en	What must be in place before a child is sent home, and how should uncertainty affect reassessment?	Adequate hydration and breathing, reliable caregivers, access to return, and concrete warning signs are needed; uncertainty should lower, not conceal, the threshold for planned reassessment.

IMF-070-03-0001-en	Why is confusing per-dose with per-day milligram-per-kilogram dosing dangerous, and what documentation reduces error?	Confusing the two causes major dosing errors, so record both calculated and administered dose and avoid trailing zeros or ambiguous decimals.

IMF-070-03-0002-en	Why can a dose calculator not resolve dosing in a child with obesity?	Obesity raises the question of whether actual, ideal, or adjusted body weight applies, and a calculator supports arithmetic but cannot choose the weight scalar or clinical regimen.

IMF-070-03-0004-en	How does oral rehydration work, and why is it given in small frequent amounts?	It uses glucose-sodium cotransport to replace water and electrolytes when the gut functions, and small frequent amounts can overcome vomiting.

IMF-070-03-0005-en	Why is maintenance fluid estimated separately from resuscitation, deficit, and ongoing loss?	Maintenance does not replace any of these components, so each is estimated separately and revised, with repeated assessment to avoid overload.

IMF-070-03-0006-en	How does hospital-acquired hyponatraemia arise in children receiving intravenous fluid?	Inappropriate hypotonic fluid combined with non-osmotic antidiuretic hormone release causes it, so weight, urine, electrolytes, glucose, perfusion, and neurological state are monitored according to risk.

IMF-070-03-0007-en	What happens if infant formula is over-diluted versus over-concentrated?	Over-dilution causes malnutrition and hyponatraemia, while over-concentration causes dehydration and renal solute burden, so formula is prepared at the stated concentration with safe water.

IMF-070-03-0009-en	Why should developmental support begin before a final aetiological diagnosis?	Early intervention uses neuroplasticity and helps caregivers shape everyday learning opportunities; support is not deferred until the cause is known.

IMF-070-03-0010-en	In neurodiversity-affirming care, why is challenging behaviour assessed rather than simply suppressed?	Behaviour may communicate pain, sensory overload, fear, or unmet need, and affirming care still treats distress, epilepsy, sleep disorder, anxiety, gastrointestinal symptoms, or danger.

IMF-070-03-0011-en	Why is a verbal promise not to self-harm insufficient in adolescent mental health care?	Safety depends on a plan identifying warning signs, coping strategies, supportive people, professional contacts, and means restriction, which a promise does not provide.

IMF-070-03-0012-en	Why can an adolescent with an eating disorder need urgent care despite looking well?	Eating disorders occur at any body size and may cause bradycardia, hypotension, electrolyte disturbance, hypoglycaemia, and hypothermia, so medical instability can exist behind a well appearance.

IMF-070-03-0014-en	Why is transition to adult care planned as a gradual process rather than a transfer at a birthday?	Young people need time to build knowledge, self-management, appointment skills, medication responsibility, and understanding of legal changes, and adult services need an accessible summary and time.

IMF-071-01-0001-en	Why is the scientific unit of primary care a person rather than a single disease episode?	Primary care treats a person embedded in family, work, community and a changing risk environment, and observing them over time alters diagnostic probability, reveals treatment effects and permits prevention.

IMF-071-01-0002-en	What distinguishes relational, informational and management continuity?	Relational continuity is repeated care by one clinician or small team; informational continuity keeps an accurate story across records and settings; management continuity aligns plans among professionals and over time.

IMF-071-01-0003-en	How does continuity help detect a subtle decline in gait, cognition, weight or self-care?	It creates a personal baseline, so a change that looks unremarkable in isolation becomes apparent relative to prior visits, and serial values are read as trajectories rather than single results.

IMF-071-01-0004-en	Why can continuity of care also become a diagnostic hazard?	Previous diagnoses can anchor later reasoning, familiar symptoms may be normalised, and social closeness can weaken professional boundaries.

IMF-071-01-0005-en	What questions does a periodic diagnostic reset ask, and what does it protect against?	Whether the original label still explains the course, whether new red flags exist, and whether treatment response supports the presumed mechanism; it counters anchoring on old diagnoses.

IMF-071-01-0006-en	Why does an integrated model of symptoms not divide them into real and psychological?	Symptoms arise from tissue signals, central processing, expectation, emotion, culture and context, so every experienced symptom involves integrated brain and body mechanisms.

IMF-071-01-0008-en	Given the inverse care law, why must treatment design include cost, storage, transport and caregiving?	Access is often least available where need is greatest, and a technically ideal plan that cannot be afforded, stored, understood or reached is not clinically effective.

IMF-071-01-0009-en	What distinguishes multimorbidity from a list of independent diagnoses?	Multimorbidity assumes no index disease; coexisting long-term conditions interact through shared causes, physiological tradeoffs, treatment burden and competing risks, forming a network.

IMF-071-01-0011-en	Why may a preventive drug be less valuable for someone with limited life expectancy, and why is this not age-based denial?	Its benefit is delayed while symptom control or fall prevention matters now; priority is individualised by danger, goals, feasibility and time to benefit, not by age.

IMF-071-01-0012-en	Why should an apparent flare of chronic illness not be assumed to be the patient's usual disease?	Exacerbations can reflect natural fluctuation, infection, medication non-adherence, environmental exposure, psychosocial stress or a new diagnosis, so alternatives must be tested.

IMF-071-01-0024-en	What distinguishes watchful waiting from neglect, and when is it unsafe?	It is active management with a working diagnosis, expected course, relief, warning signs and planned review; it is unsafe if deterioration may be rapid, return is impossible or uncertainty is hidden.

IMF-071-02-0001-en	Why should all major concerns be identified before the first one is explored in depth?	Patients often present a safe symptom before disclosing fear of cancer, violence, substance use or distress, and asking about hopes and worries reduces late surprises.

IMF-071-02-0002-en	How should priorities be negotiated when consultation time is limited?	Immediate danger comes first, then the issue most important to the patient and those with high preventive value; unresolved concerns receive a named follow-up rather than disappearing.

IMF-071-02-0003-en	Why can a test with good sensitivity and specificity yield mostly false positives in primary care?	When applied indiscriminately to low-risk people, low pre-test probability means most positive results are false.

IMF-071-02-0008-en	Why does normal spirometry between episodes not exclude asthma, and why does wheeze alone not prove it?	Asthma diagnosis rests on demonstrating variable symptoms and airflow limitation, so function may be normal between episodes, while wheeze is not by itself a demonstration of variable obstruction.

IMF-071-02-0009-en	Why does a normal resting electrocardiogram not exclude arrhythmia in a patient with palpitations?	Arrhythmia may be intermittent, so the symptom must be correlated with rhythm using a monitoring device matched to event frequency.

IMF-071-02-0010-en	Why must imaging abnormalities in persistent pain be matched to the clinical pattern?	Imaging abnormalities are common in asymptomatic people, so a finding explains pain only if it fits the clinical pattern.

IMF-071-02-0011-en	In long-lasting symptoms after infection, why avoid forced graded activity, and what is used instead?	Post-exertional exacerbation means forced activity can predictably worsen symptoms, so pacing and multidisciplinary rehabilitation tailored to phenotype are used.

IMF-071-02-0012-en	Why do symptom combinations, rather than single alarm symptoms, determine urgency in suspected cancer?	Most individual alarm symptoms are non-specific, so combinations, duration, age and trajectory carry the diagnostic weight.

IMF-071-02-0013-en	Why is a recent negative screening test not reassurance for a symptomatic patient?	A negative screen reduces risk only for the conditions and intervals it covers, so persistent symptoms still require the appropriate diagnostic pathway.

IMF-071-03-0001-en	What should every addition to a long-term management plan specify, and why?	A purpose, expected benefit, burden, review point and stopping rule, because longitudinal care must reduce preventable harm without overwhelming the person.

IMF-071-03-0002-en	When may a condition-specific target be relaxed, and why should age alone not exclude effective therapy?	When hypoglycaemia, falls, hypotension, kidney injury or treatment workload outweigh incremental benefit; age alone is not a reason if function and time to benefit are favourable.

IMF-071-03-0003-en	Why use one integrated plan with named owners rather than parallel specialty plans?	Contradictory advice is resolved by direct communication, and naming who owns each monitoring task and who coordinates prevents the patient becoming the only information conduit.

IMF-071-03-0004-en	How does a prescribing cascade arise, and how is it detected?	A drug adverse effect is misdiagnosed as a new condition and treated with another drug; new symptoms should be timed against medication starts, dose changes, renal decline and interacting agents.

IMF-071-03-0005-en	Which drugs are prioritised for deprescribing, and how is withdrawal made safe?	Drugs without indication, duplicated therapy, high-risk combinations and preventives whose time to benefit no longer fits goals; taper where needed, change a few at once and monitor the target outcome.

IMF-071-03-0006-en	How should a monitoring interval be chosen, and what goes wrong at either extreme?	By kinetics, baseline stability, intervention risk and actionability; testing too often detects random variation and adds burden, testing too rarely misses deterioration.

IMF-071-03-0009-en	Why is the right response to non-adherence diagnosis of the barrier rather than moral judgement?	Non-adherence may be intentional, unintentional or structurally imposed, arising from adverse effects, complexity, cost, housing, memory, language or depression, each needing a different fix.

IMF-071-03-0010-en	Who holds responsibility while a referral is pending, and what does a long wait require?	The referrer retains responsibility until transfer is accepted and must manage interim risk; long waits need bridging care and escalation criteria.

IMF-071-03-0011-en	Why is the period just after hospital discharge high risk, and what should early contact check?	Medication discrepancy, functional decline, unresolved tests and misunderstanding cluster then, so early contact reviews symptoms, observations, medicines, support and follow-up.

IMF-072-01-0002-en	Using the International Classification of Functioning, how are weakness, difficulty dressing and inability to return to work classified?	Weakness is an impairment, difficulty dressing is an activity limitation, and inability to return to work is a participation restriction.

IMF-072-01-0004-en	How does a useful clinical approach combine the medical and social models of disability?	The medical model identifies pathology and treatment and the social model identifies barriers, discrimination and exclusion, so clinicians treat remediable disease while changing environments that unnecessarily disable.

IMF-072-01-0005-en	Why does walking ten metres in a quiet clinic not establish functional ability?	Function is task- and context-specific, so it does not show ability to cross a road, climb home stairs or sustain work; assessment asks what the person needs to do, under what conditions and at what cost.

IMF-072-01-0006-en	Why does bed rest increase the risk of complications beyond muscle weakness?	It rapidly reduces plasma volume, aerobic capacity, insulin sensitivity and orthostatic tolerance, increases bone resorption and shortens connective tissue, making pressure injury, thrombosis, delirium and respiratory complications more likely.

IMF-072-01-0007-en	Why can strength improve early in resistance training before muscle has hypertrophied?	Strength depends on motor-unit recruitment and neural drive as well as cross-sectional area, and early gains are substantially neural, with hypertrophy following later.

IMF-072-01-0012-en	What distinguishes restitution, compensation and substitution in recovery?	Restitution restores the original function through healing and neural reorganisation, compensation achieves the task differently, and substitution uses equipment, environmental modification or assistance.

IMF-072-01-0013-en	What tradeoff exists between early compensation and insisting on restitution?	Early compensation can sometimes limit practice-dependent recovery, while insisting on restitution alone can delay independence.

IMF-072-01-0015-en	How do variable practice and task-specific practice differ in what they improve?	Variable practice improves transfer to other conditions, while task-specific practice improves the trained activity itself.

IMF-072-01-0016-en	What examination features distinguish upper from lower motor-neuron weakness?	Upper motor-neuron lesions alter selective control and cause hyperreflexia and possible spasticity, whereas lower motor-neuron lesions cause weakness, atrophy, fasciculation and reduced reflexes.

IMF-072-01-0017-en	Why should spasticity treatment target a functional problem rather than tone measured in isolation?	Spasticity can impede hygiene, gait, sleep or care, but it sometimes supports standing or transfers, so reducing tone is useful only when it serves function.

IMF-072-01-0018-en	What distinguishes aphasia, dysarthria and dysphonia, and why does the distinction matter?	Aphasia affects language, dysarthria affects speech motor execution and dysphonia affects voice, so each requires a different rehabilitation strategy.

IMF-072-01-0019-en	How can acute protective avoidance of movement become persistent pain-related disability?	Fear, deconditioning, sensitisation and reduced self-efficacy perpetuate it, so rehabilitation explains safety and uses graded task exposure without implying the pain is imaginary.

IMF-072-01-0020-en	Why does post-exertional symptom exacerbation call for pacing rather than automatic graded progression?	It differs from ordinary deconditioning: symptoms are exacerbated after exertion, so load must be paced to the person rather than increased automatically.

IMF-072-01-0021-en	What explains early versus later recovery after stroke, and why does a test plateau not end rehabilitation?	Early spontaneous recovery reflects reperfusion, resolution of oedema and network reorganisation, followed by slower practice-dependent change; a test plateau does not prove further functional adaptation is impossible.

IMF-072-01-0022-en	Why is autonomic dysreflexia dangerous in spinal cord injury above the mid-thoracic region?	Stimuli from the bladder, bowel, skin or elsewhere can provoke an autonomic response that causes dangerous hypertension.

IMF-072-01-0023-en	Why can apparent physical recovery after traumatic brain injury be misleading?	Injury may impair memory, executive control, behaviour and emotion, so good physical recovery can conceal cognitive disability.

IMF-072-01-0024-en	Why should rehabilitation goals not be reduced to checklist metrics or a return to the prior body?	Relevance is set by the person's identity, culture, roles, work and acceptable tradeoffs, and recovery can include learning to live well with persistent impairment.

IMF-072-02-0001-en	Why is direct observation of tasks essential in rehabilitation assessment?	The same lesion can produce very different lives depending on cognition, pain, housing, support, equipment, employment and access, so disease diagnosis must be supplemented by functional diagnosis.

IMF-072-02-0002-en	Why does completing a task once in assessment not establish functional ability?	Fatigue and variability matter: the person may not manage it repeatedly, safely or within a practical time, so ask about good and bad days, recovery and near falls.

IMF-072-02-0003-en	Why must caregiver capacity be assessed separately from patient needs?	Caregivers have their own health, employment and willingness, and care based on an assumed unlimited family contribution is unsafe.

IMF-072-02-0005-en	Why does timing matter for electrodiagnostic studies, and what can a normal study fail to exclude?	Denervation changes evolve after injury, so early studies may miss them; a normal study does not exclude small-fibre neuropathy, central disease or every early lesion.

IMF-072-02-0006-en	What makes cardiopulmonary exercise testing able to distinguish causes of exercise limitation?	It measures ventilation, gas exchange, circulation and muscle use together during progressive work, so the pattern of variables separates cardiac, pulmonary, peripheral or deconditioning limitation.

IMF-072-02-0007-en	What distinguishes the minimum detectable change from the minimal clinically important difference?	The minimum detectable change reflects measurement error, while the minimal clinically important difference reflects perceived relevance; neither is universal across populations.

IMF-072-02-0008-en	Why do multifactorial interventions outperform a generic instruction to be careful after a fall?	Falls arise from interacting balance, strength, vision, cognition, blood pressure, feet, continence, environment and medication, so each contributing factor must be addressed.

IMF-072-02-0013-en	Why is neurogenic bladder assessment not based on symptoms alone?	Symptoms do not reliably indicate bladder pressure, yet high-pressure storage can cause reflux and renal damage, so residual volume, renal function, imaging or urodynamics are used according to risk.

IMF-072-03-0014-en	Why can a previously successful rehabilitation plan fail, and what should lack of progress prompt?	Growth, ageing, pregnancy, new disease and caregiver change can destabilise it; lack of progress prompts review of diagnosis, dose, learning conditions, mood, pain, equipment, environment and the goal itself.	Integrated Medical Foundations; chapter 72, TTS module 3; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: a89cba2676e31c811c47d9edc38499e64ff024a84b996d542779ce4588ce04a7; editorial review pending	imf lang::en chapter::072 module::072-03 review::pending
IMF-073-01-0001-en	Why does patient safety attribute most adverse events to systems rather than to one careless individual, and why is blame alone insufficient?	Most adverse events arise from interactions among people, tasks, technology, environment, organisation, and patient factors, so blame without system learning leaves the hazards intact.	Integrated Medical Foundations; chapter 73, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: c0947ecb4503ce082797bcb2eed50a0c90b5fde0ea8f21e7bceb27a002ad4856; editorial review pending	imf lang::en chapter::073 module::073-01 review::pending
IMF-073-01-0002-en	What distinguishes a slip, a lapse, and a mistake?	A slip is an execution failure, often during familiar automatic work; a lapse is a failure of memory; a mistake reflects a flawed rule-based or knowledge-based decision.

IMF-073-01-0003-en	How does a violation differ from an error, and why does the distinction matter?	An error is failure of a planned action or use of an incorrect plan, whereas a violation is a deliberate departure from a rule; the distinction guides both prevention and accountability.

IMF-073-01-0004-en	What distinguishes a near miss, a no-harm incident, and an adverse event?	A near miss is intercepted before injury; a no-harm incident reaches the patient without discernible injury; an adverse event causes harm related to care rather than the underlying disease.

IMF-073-01-0005-en	How does outcome bias distort the judgement of care, and how should safety systems respond?	It makes the same action appear less acceptable after a severe result, although not every bad outcome is an error, so systems analyse process and context while recognising that consequences matter.

IMF-073-01-0006-en	Why does harm still occur in a system protected by multiple barriers?	Every barrier has weaknesses, and harm occurs when active failures align with latent conditions such as understaffing, poor layout, ambiguous labelling, incompatible software, or production pressure.

IMF-073-01-0007-en	What does the Swiss-cheese metaphor misrepresent, and why study successful adaptation as well as failure?	It can imply static holes, but real systems adapt as clinicians trade efficiency against thoroughness, and work-as-done differs from work-as-imagined; successful adaptation shows how safety is normally created.

IMF-073-01-0008-en	Why does redundancy not automatically increase safety, and how are standardisation and flexibility balanced?	Redundancy can introduce diffusion of responsibility or conflicting information; standardisation reduces unwanted variation, while flexibility is needed when cases fall outside the standard.

IMF-073-01-0009-en	Why is prospective memory a particular safety weakness, and what supports it?	Remembering to act later is especially fragile during interruptions; checklists and external reminders support cognition when they are integrated into the workflow.

IMF-073-01-0010-en	How can expertise increase the risk of anchoring, and what creates an opportunity to reframe?	Expertise improves pattern recognition, but familiar scripts can dominate contradictory evidence; diagnostic timeouts and second opinions create opportunities to reframe the problem.	Integrated Medical Foundations; chapter 73, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: c0947ecb4503ce082797bcb2eed50a0c90b5fde0ea8f21e7bceb27a002ad4856; editorial review pending	imf lang::en chapter::073 module::073-01 review::pending
IMF-073-01-0011-en	Why is naming cognitive biases insufficient, and what strategies work better?	Knowing the names does not reliably prevent bias; better strategies alter information flow by requiring alternatives, displaying trends, separating independent estimates, prompting disconfirming evidence, and creating outcome feedback.	Integrated Medical Foundations; chapter 73, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: c0947ecb4503ce082797bcb2eed50a0c90b5fde0ea8f21e7bceb27a002ad4856; editorial review pending	imf lang::en chapter::073 module::073-01 review::pending
IMF-073-01-0012-en	Why is fatigue addressed by system interventions rather than by urging individuals to be more resilient?	Circadian low points and extended wakefulness impair judgement even when clinicians feel adapted, so rostering, protected breaks, task design, and supervision are needed; exhortation cannot fully compensate.	Integrated Medical Foundations; chapter 73, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: c0947ecb4503ce082797bcb2eed50a0c90b5fde0ea8f21e7bceb27a002ad4856; editorial review pending	imf lang::en chapter::073 module::073-01 review::pending
IMF-073-01-0013-en	Why can performance look stable under rising workload and then fail suddenly?	Performance often remains stable until adaptive capacity is exhausted, after which a small additional demand produces disproportionate failure.

IMF-073-01-0014-en	Why are interruptions managed by design rather than simply eliminated?	Some interruptions communicate urgent information, so safety design separates necessary from avoidable interruption, protects high-risk tasks such as medication preparation, and provides a reliable way to resume.	Integrated Medical Foundations; chapter 73, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: c0947ecb4503ce082797bcb2eed50a0c90b5fde0ea8f21e7bceb27a002ad4856; editorial review pending	imf lang::en chapter::073 module::073-01 review::pending
IMF-073-01-0015-en	Why should training not be the sole remedy for defective design, and which design controls work better?	Look-alike names and packaging or hidden defaults invite predictable mistakes; forcing functions physically prevent unsafe action, constraints reduce options, and standardisation and affordances make intended use evident.

IMF-073-01-0016-en	Why can adding more alarms worsen detection?	High false-alarm rates cause desensitisation, competing noise, and delayed response; alarms should identify an actionable state with sufficient priority and specificity.

IMF-073-01-0017-en	What steps make communication closed-loop, and where is it especially valuable?	The sender names the recipient, states the message, receives a read-back, and confirms correctness, closing gaps from ambiguity and missing confirmation; it is especially valuable in resuscitation, medication orders, and critical results.

IMF-073-01-0018-en	What does psychological safety mean, and how can leaders counter hierarchy that suppresses challenge?	Team members can ask, admit uncertainty, and raise risk without humiliation, while standards remain; leaders invite dissent, state their own uncertainty, and respond appreciatively even when a concern proves unfounded.

IMF-073-01-0019-en	Which situations increase the risk of medication harm, and what reduces discrepancy?	High-alert drugs, renal or hepatic impairment, allergy labels, weight-based dosing, infusion concentration, transitions, and multiple prescribers raise risk; reconciliation and indication-linked prescribing reduce discrepancy.

IMF-073-01-0020-en	Why should the necessity of catheters and lines be reviewed daily?	Device use is one driver of healthcare-associated infection, and the safest catheter or line is often the one no longer present.

IMF-073-01-0021-en	Why do early-warning scores support rather than replace clinical judgement?	They aggregate observations but can miss clinical concern, atypical baselines, or abrupt change between measurements, so they work only within a full detection-and-response system.

IMF-073-01-0022-en	What is failure to rescue, and which system factors cause it?	It is failure to recognise or manage a complication in time, caused by normalising abnormal observations, diffusion of responsibility, delayed review, communication barriers, and mismatch between patient needs and ward capability.

IMF-073-01-0023-en	How does a just culture decide the response to an incident, and why does reporting depend on it?	It differentiates human error, at-risk behaviour, reckless conduct, and intentional harm, matching responses to context and choice; staff do not report when they expect punishment, futility, or excessive burden.

IMF-073-01-0024-en	Why cannot wellbeing programmes resolve the safety risk associated with burnout?	Burnout is not an individual defect but reflects workload, moral distress, inefficient systems, violence, discrimination, and inadequate control, so it cannot substitute for safe staffing and functional tools.

IMF-073-02-0001-en	What must be secured immediately after an incident, and why does this take priority over investigation?	Care for the affected patient, prevention of further exposure, preservation of equipment and records, notification of leaders, and staff support come first, because investigation must not delay treatment.

IMF-073-02-0002-en	What does open disclosure involve, and why should uncertainty not justify silence?	It communicates what is known, expresses regret, explains care and investigation, and commits to further information; patients and families may hold facts invisible to the organisation.

IMF-073-02-0003-en	Why must hindsight be kept out of earlier decision points when reconstructing an incident?	The aim is to explain why decisions appeared reasonable using the information, goals, workload, and constraints present at each moment; knowledge of the outcome was not available then.

IMF-073-02-0004-en	Why do electronic timestamps need interpretation when building a chronology?	They can reflect delayed entry, automatic processes, copied notes, or clock differences rather than the true time of action.

IMF-073-02-0005-en	Why are statements such as "staff failed to follow policy" not accepted as causes?	They are descriptions; investigators must ask whether the policy was accessible, workable, trained, monitored, and compatible with demand, what information was missing, and why recovery did not occur.

IMF-073-02-0006-en	What makes a factor causal rather than merely contributory, and what limits counterfactual reasoning?	A condition is causal if changing it would plausibly alter the outcome in the reconstructed mechanism, but counterfactuals must consider whether another pathway would still have produced harm.

IMF-073-02-0007-en	Why is diagnostic error often a distributed process rather than one wrong thought?	Diagnosis spans access, symptom elicitation, examination, testing, interpretation, follow-up, and referral, and fails when results miss the right person, responsibility is unclear, or non-attendance triggers no follow-up.	Integrated Medical Foundations; chapter 73, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: c76ce34e5b3ad3e16df3541efe62511729610f68bd6719cdb3b30e717a01727c; editorial review pending	imf lang::en chapter::073 module::073-02 review::pending
IMF-073-02-0008-en	How can a reasonable initial diagnosis become unsafe, and what should the investigation track?	It becomes unsafe if disconfirming evidence is ignored, so investigators track when the diagnosis could first reasonably have been made and which later opportunities existed.

IMF-073-02-0009-en	Why can an independent double-check fail to catch a medication error?	Checks are weak when both clinicians share the same assumption or one merely confirms the other's calculation, and when they do not focus on the high-risk elements.

IMF-073-02-0010-en	Why should the severity of outcome not decide whether a medication incident's mechanism matters?	Harm without error can still reveal ways to improve monitoring or risk selection, and a large error that caused no harm by chance deserves learning before it recurs.

IMF-073-02-0012-en	Why is statistical process control preferred to reacting to every fluctuation or comparing before-and-after averages?	It separates common-cause variation inherent in the process from special-cause signals; reacting to every fluctuation destabilises a process, and simple averages can conceal temporal change.

IMF-073-02-0014-en	What do Safety-II and positive deviance study, and what limit applies to successful workarounds?

IMF-073-03-0001-en	Why is "improve safety" an inadequate improvement aim?	An aim must identify population, outcome, magnitude, and timeframe to guide action; a vague aim does not, and the target should be ambitious enough to matter yet realistic enough to mobilise learning.

IMF-073-03-0002-en	What does a driver diagram link, and why must it carry a theory?	It links the aim to primary system conditions, secondary processes, and candidate changes; the theory explains why each intervention might influence the outcome.

IMF-073-03-0003-en	What makes a plan-do-study-act cycle a learning method rather than merely doing?	It predicts what will happen, tests under realistic conditions, compares results with the prediction, and adapts, repeating across shifts, staff, patient groups, and pressure before wider use.

IMF-073-03-0004-en	Why may an intervention that succeeded in one unit fail elsewhere, and what does scaling require?	Context differs between units; scale requires standardised core elements, local adaptation, training, data, technical support, and leadership ownership.

IMF-073-03-0005-en	Why is education alone a weak implementation strategy, and what are stronger actions?	Education fails when the barrier is equipment, staffing, or interface design; strong actions eliminate hazards, use forcing functions, standardise, simplify, or make status visible, while weak ones rely on vigilance.

IMF-073-03-0007-en	If staff routinely bypass a rule, what should be investigated before escalating punishment?	Whether the rule is impractical, the risk is misunderstood, or incentives conflict; users should be involved and obsolete overlapping forms retired to limit checklist fatigue.

IMF-073-03-0008-en	How should electronic systems and patient portals support diagnostic safety without shifting responsibility?	Systems should display trends and unresolved abnormalities rather than burying them in separate screens; portals add a safety layer but cannot transfer responsibility to patients.

IMF-073-03-0009-en	Why does graded assertiveness not overcome hierarchy on its own, and what must an escalation policy state?	Scripts do not neutralise hierarchy unless leaders respond safely; policies state whom to contact, expected response time, alternatives when no response occurs, and how patients or families can activate review.

IMF-073-03-0010-en	What new risks do computerised orders introduce, and what safeguards should automation have?	They remove handwriting error but add wrong-patient selection, default error, copy-forward, alert fatigue, and downtime risk; automation should display uncertainty, allow challenge, and have monitored fallback processes.

IMF-073-03-0011-en	Why cannot voluntary incident reports estimate incidence, and what compensates?	Reporting varies, so reports identify hazards but not rates; they are combined with record review, trigger tools, surveillance, complaints, claims, and direct observation.

IMF-073-03-0012-en	Why should patients not be blamed for failing to intercept a professional error?	Patients can help confirm identity, medication, procedure, and allergies, but safety remains the service's responsibility, and their ability to speak up is limited by illness, language, disability, trauma, and hierarchy.

IMF-073-03-0013-en	When spreading an intervention, what must be preserved and what may be adapted?	Preserve the causal core and adapt the peripheral form, because fidelity without context can fail and adaptation without theory can remove the active ingredient.

IMF-073-03-0014-en	How can a new protocol cause improvement harm, and how is this detected?	It can consume nursing time, delay another treatment, or shift work to patients; balancing measures and frontline observation detect these opportunity costs.

IMF-074-01-0001-en	Scarcity changes priorities in disaster and austere medicine. What does it not change?	It does not suspend clinical reasoning or accountability, because the task is to achieve the greatest justified benefit without abandoning individual dignity.

IMF-074-01-0002-en	What distinguishes a mass-casualty incident from a disaster?	A mass-casualty incident is patient need exceeding immediately available resources, whereas a disaster disrupts community function beyond local capacity and may be sudden or slowly evolving.

IMF-074-01-0003-en	Why can prevention in the disaster cycle save more lives than heroic response?	Impact depends on vulnerability and exposure as much as on the hazard, so resilient buildings, vaccination, land use, heat planning and supply chains reduce harm before the event occurs.

IMF-074-01-0004-en	Why are remote, rural and resource-limited settings not interchangeable categories?	Remote means far from timely definitive care, rural may mean stable communities with limited specialist and retrieval capacity, and resource limitation includes temporary scarcity even in wealthy systems.

IMF-074-01-0005-en	How does mass-casualty triage differ in priority from everyday triage?	Everyday triage prioritises the sickest, whereas mass-casualty triage may prioritise those most likely to survive with immediate limited intervention, because resources cannot meet all needs.

IMF-074-01-0006-en	Why does initial triage deliberately sacrifice diagnostic detail, and how can simple actions alter the result?	Speed matters more than detail when many patients await sorting; opening an airway, controlling haemorrhage or giving an antidote can change a patient's category.

IMF-074-01-0007-en	Why is triage repeated, and what harm do over-triage and under-triage each cause?	Deterioration, treatment response, resource arrival and evacuation delay change priorities; over-triage consumes scarce resources, while under-triage delays salvageable patients.

IMF-074-01-0008-en	What does expectant classification mean, and what obligations remain?	Survival-directed resources cannot currently achieve benefit relative to competing needs; analgesia, symptom relief, warmth, communication and presence remain obligations, and category is reconsidered as capacity changes.

IMF-074-01-0009-en	Why should clinical expertise inform but not replace incident command, and why are redundant communications needed?	Command creates clear roles for leadership, operations, planning, logistics and safety within a limited span of control; power, internet and cellular networks may fail.

IMF-074-01-0010-en	Why must scene safety precede patient contact, and how do the hot, warm and cold zones differ?	Responders must not become additional casualties; hot zones contain active danger needing specialised protection, warm zones support decontamination, and cold zones permit safer treatment.

IMF-074-01-0011-en	Why should casualty distribution be coordinated rather than sending patients to the nearest facility?	Coordinating collection, transport and destination prevents uncontrolled movement toward the nearest facility, and destinations are chosen by capability and capacity rather than distance alone.

IMF-074-01-0012-en	After an explosion, what can tympanic rupture tell you, and what can it not?	It can indicate blast exposure but does not reliably predict primary lung injury, so its absence or presence should not decide pulmonary risk.

IMF-074-01-0013-en	Why is undirected washing not universally safe in chemical incidents?	Water-reactive or oily agents require substance-specific procedures, so decontamination must follow the agent rather than a single routine.

IMF-074-01-0016-en	What features suggest a biological event, and why should security concerns not override care?	Unusual clusters, rare syndromes, unexpected season or geography, severe disease in healthy people or animal illness; natural outbreak and deliberate release look identical initially, and patient care still comes first.

IMF-074-02-0004-en	Why should shock be recognised before hypotension, especially in children?	Mental change, cool skin, delayed refill, weak pulse, tachypnoea and oliguria show impaired perfusion earlier, and children compensate then deteriorate abruptly.

IMF-074-02-0005-en	What does a negative limited point-of-care ultrasound scan mean when the clinical pattern is concerning?	It does not exclude injury or replace transport, because its value depends on training, battery, probe, image quality and the question asked.

IMF-074-02-0006-en	Why can a normal oxygen saturation soon after chest trauma be falsely reassuring?	Pulmonary contusion can worsen over hours, so early normal saturation does not predict later respiratory failure.

IMF-074-02-0007-en	Why does a palpable pulse not exclude compartment syndrome?	Pulses can remain present, so the diagnosis rests on escalating pain, pain on passive stretch, tension, sensory change and later weakness.

IMF-074-02-0008-en	In severe exertional heat illness, how should temperature be measured and when should cooling start?	Rectal temperature best approximates core temperature because peripheral measures mislead, and cooling starts immediately without waiting for laboratory confirmation.

IMF-074-02-0009-en	Which findings after ascent indicate cerebral or pulmonary oedema rather than acute mountain sickness alone?	Ataxia or altered consciousness indicates cerebral oedema; dyspnoea at rest, cough, crackles or low saturation suggest pulmonary oedema, and descent is not delayed for imaging.

IMF-074-02-0010-en	Why may a negative rapid malaria test need repetition?	Rapid tests can lose sensitivity and specificity in field conditions and temperature extremes, so a negative result does not settle the question when exposure and illness fit.

IMF-074-02-0011-en	In a toxic exposure, why can standard pulse oximetry and responder symptoms both matter?	Standard pulse oximetry can miss carbon monoxide, and symptoms among responders may reveal an ongoing dangerous atmosphere.

IMF-074-02-0012-en	If birth occurs before retrieval, what do most newborns need and when is ventilation required?	Most need drying, warmth, positioning and stimulation; apnoea or ineffective breathing requires ventilation, while maternal stabilisation proceeds simultaneously.

IMF-074-02-0013-en	Why must confusion or agitation in a disaster survivor not be assumed to be psychological?	It can also reflect hypoxia, head injury, infection, toxin, glucose disturbance, withdrawal, pain or medication interruption, which remain important even in traumatic circumstances.

IMF-074-02-0014-en	When is a treatment trial diagnostically useful, and why does improvement rarely prove cause?	Only when response is meaningful and failure can be detected; improvement after analgesia, fluid or bronchodilator supports the physiology but rarely identifies the underlying cause.

IMF-074-03-0001-en	Why may two-person bag-mask ventilation be safer than early intubation in austere settings?	Premature intubation without monitoring, drugs or rescue capability adds risk, and intubation also depends on transport, battery, oxygen supply and ventilator capacity.

IMF-074-03-0006-en	When is a longer direct transfer preferred, and when is the nearest facility needed instead?	A direct transfer to definitive care may be safer than repeated transfers, but current instability may require the nearest resuscitation facility.

IMF-074-03-0008-en	Which criteria must scarcity allocation exclude, and how should age and disability be handled?	Social worth, wealth, political influence, race, disability stereotypes and ability to advocate are excluded; age and disability count only through relevant clinical prognosis, not categorical exclusion.

IMF-074-03-0009-en	When can withdrawing a scarce resource be ethically equivalent to withholding it?	When reassessment shows it is not achieving the agreed benefit, though withdrawal is emotionally harder; triage teams separate this allocation from bedside advocacy.

IMF-074-03-0010-en	Why are confidential support and real rest preferred over compulsory emotional debriefing for responders?	Acute stress reactions are common, and forcing emotional disclosure is less helpful than confidential support, rest and rotation away from relentless high-intensity work.

IMF-074-03-0012-en	When formularies change after a disaster, which treatments must not be stopped abruptly?	Steroids, insulin, antiseizure drugs, benzodiazepines, opioids and psychiatric treatment; regimens may be simplified, but abrupt withdrawal is avoided and refill points and paper summaries support continuity.

IMF-075-01-0001-en	Why are anatomical terms treated as relational conventions rather than descriptions from the observer's viewpoint?	Their meaning must stay consistent when the body changes position, an image is viewed in another plane, or organs shift with development, breathing, filling, or disease.

IMF-075-01-0002-en	A patient lies prone and the image is rotated on screen. Why does the meaning of right and left not change?	Right and left always refer to the subject, not the observer, so body position or display rotation leaves the anatomical meaning unchanged.

IMF-075-01-0003-en	What distinguishes internal and external from medial and lateral?	Internal and external describe an inside-outside relationship to a specified structure, whereas medial and lateral refer to the midline, so a point inside an organ wall is not necessarily nearer the midline.

IMF-075-01-0006-en	Why do the apparent relationships on an anatomical section depend on more than the anatomy itself?	A section is the exposed surface created by a cut, so what it shows depends on the plane cut (sagittal, coronal, transverse, or oblique) and on the viewing convention.

IMF-075-01-0019-en	What distinguishes adventitia from serosa as the outer layer of an organ?	Adventitia blends the organ with surrounding connective tissue, whereas serosa provides a smooth free surface; which one forms depends on the organ's relation to a cavity.

IMF-075-01-0021-en	How do a malformation, a disruption, and a deformation differ in origin?	A malformation results from an intrinsic developmental process, a disruption from destruction of previously normal tissue, and a deformation from mechanical forces.

IMF-075-02-0003-en	Why should a visceral fascial space be described by its boundaries and contents rather than by its name alone?	Nomenclature varies among disciplines, and some spaces are real potential spaces while others are surgical or radiological concepts based on loose areolar planes.

IMF-075-02-0004-en	How does rising volume within an anatomical compartment injure its contents?	The compartment is bounded by relatively unyielding tissue, so added volume raises pressure, which impairs venous outflow, capillary perfusion, nerve conduction, and muscle viability.

IMF-075-02-0005-en	Why can pulses remain present in acute compartment syndrome, and which clues appear early?	Arterial pressure exceeds compartment pressure, so pulses may persist; pain out of proportion and pain on passive stretch are early clues, with sensory change and weakness following.

IMF-075-02-0006-en	How does abdominal compartment syndrome produce organ dysfunction?	Sustained high intra-abdominal pressure from wall tension, fluid, bleeding, bowel distension, and capillary leak reduces renal perfusion, venous return, respiratory compliance, and visceral blood flow.

IMF-075-02-0007-en	Why can gradual arterial stenosis be tolerated when acute occlusion causes infarction despite visible connections?	Collateral circulation depends on time for remodelling as well as pre-existing anastomoses, so gradual narrowing lets collateral channels enlarge, whereas acute occlusion does not.

IMF-075-02-0008-en	Why do vertebral venous channels provide routes for metastasis and infection?	Venous plexuses often lack valves and permit bidirectional spread, and the vertebral channels connect pelvis, abdomen, thorax, and cranial cavity.

IMF-075-02-0009-en	How does raised portal pressure lead to varices?	Portosystemic anastomoses enlarge as a physiological decompression, producing oesophageal and gastric varices, rectal collaterals, and abdominal-wall veins that can bleed lethally.

IMF-075-02-0010-en	Why does lesion localisation compare motor, sensory, and reflex patterns across roots, trunks, cords, and named nerves?	Plexuses redistribute fibres, so a peripheral nerve contains contributions from several roots rather than mapping onto a single root.

IMF-075-03-0004-en	How does the silhouette sign localise disease on a chest radiograph?	Loss of the border between two structures of similar density indicates adjacent disease: a lost right heart border suggests right middle-lobe opacity, a lost hemidiaphragm a lower lobe.

IMF-075-03-0005-en	Why can a CT finding be invisible on one window yet evident on another?	Window width sets the displayed attenuation range and window level its centre, so lung, soft-tissue, brain, and bone windows reveal different structures from the same data.

IMF-076-03-0006-en	How are structures arranged in the femoral triangle, and why is the femoral canal a hernia site?	Lateral to medial lie femoral nerve, artery, vein and lymphatic space; the sheath excludes the nerve, and the canal medial to the vein permits venous expansion, leaving a space where hernia occurs.

IMF-077-01-0002-en	Why can a cervical rib or fibrous band cause neurovascular symptoms at the root of the neck, and what caution applies to finding one?	Subclavian artery and brachial plexus cross a crowded passage between the scalenes, so such structures can compress them; but anatomical narrowing alone does not establish symptomatic thoracic-outlet syndrome.

IMF-077-02-0008-en	What actually closes heart valves, and what is the true role of papillary muscles?	Closure depends on pressure reversal and cusp coaptation, not muscle contraction; papillary muscles prevent atrioventricular leaflet prolapse during systole but do not close valves.

IMF-077-02-0009-en	Why must atrial activation pass through the atrioventricular bundle to reach the ventricles?	The fibrous cardiac skeleton electrically insulates atria from ventricles everywhere except through the atrioventricular conduction bundle.

IMF-077-02-0010-en	How is coronary dominance defined, and why does it matter clinically?	Dominance is defined by the origin of the posterior interventricular artery, usually right coronary; it affects inferior and posterior territories and atrioventricular-node supply.

IMF-077-02-0011-en	Why does acute coronary occlusion commonly infarct myocardium, and why is subendocardium most vulnerable?	Coronaries are functional end arteries, so gradual narrowing may enlarge collaterals but acute occlusion does not; subendocardium suffers because systolic intramural pressure compresses vessels and perfusion is mainly diastolic.

IMF-077-02-0012-en	Why is cardiac ischaemic pain referred to the chest and medial arm, yet cardiac reflexes run in the vagus?	Visceral pain afferents travel with sympathetics to upper thoracic segments, producing referred chest and medial arm pain, whereas reflex afferents travel with the vagus.

IMF-077-02-0013-en	Why can an aortic aneurysm or left atrial enlargement cause hoarseness?	The left recurrent laryngeal nerve lies near the ligamentum arteriosum and aortic arch, so aneurysm or an enlarged left atrium can compress or affect it.

IMF-077-02-0014-en	Why are cardiac auscultation sites not the same as the surface projections of the valves?	They are locations where valve sound transmits toward the chest wall, so anatomy predicts radiation while echocardiography shows the actual moving valves.

IMF-077-03-0002-en	How do incomplete or accessory fissures change disease behaviour and treatment?	Fissures limit interlobar collateral flow, so incomplete or variant fissures permit collateral ventilation and spread, and bronchoscopic lung-volume treatments depend on fissural integrity.

IMF-077-03-0003-en	How does the relation of bronchus and pulmonary artery at the hilum differ between right and left?	At the right hilum the upper-lobar bronchus commonly lies above the pulmonary artery, whereas on the left the pulmonary artery lies above the main bronchus.

IMF-077-03-0004-en	Why does aspirated material more often enter the right airways, and what finally decides where it lodges?	The right main bronchus is generally wider, shorter, and more vertical, but body posture determines the dependent segments where material finally goes.

IMF-077-03-0005-en	Why can a bronchopulmonary segment be resected as a unit?	Each segment is a pyramidal functional unit supplied by its own segmental bronchus and arterial branch, with veins running between segments along connective-tissue planes.

IMF-077-03-0006-en	How can collateral ventilation be both protective and harmful?	Interalveolar pores and bronchiolar channels can maintain aeration beyond an obstructed small airway, but the same pathways permit spread of disease.

IMF-077-03-0007-en	What makes pulmonary sequestration anatomically distinct, and why must such variants be mapped before intervention?	Sequestration receives systemic arterial supply and lacks normal bronchial connection; variant vessels may stay silent until infection, haemorrhage, surgery, or imaging reveals them.

IMF-077-03-0008-en	How does surfactant stabilise the alveoli, and what follows its loss?	Produced by type two pneumocytes, it lowers surface tension, stabilises small alveoli, increases compliance, and reduces fluid transudation, so loss or inactivation contributes to collapse and respiratory distress.	Integrated Medical Foundations; chapter 77, TTS module 3; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: d0008f241471c2eaa92b6acea34ddbac20ef38caf8aa289a2f2b29977c233157; editorial review pending	imf lang::en chapter::077 module::077-03 review::pending
IMF-077-03-0009-en	Why does bronchial circulation contribute to physiological shunt?	Much bronchial arterial blood, after supplying airways and supporting tissue, returns through pulmonary veins to the left heart.

IMF-077-03-0010-en	Why is pulmonary infarction uncommon after embolism, and when does it become more likely?	Dual pulmonary and bronchial supply limits infarction, but it becomes more likely when cardiac output or bronchial circulation is compromised.

IMF-077-03-0011-en	Why is severe haemoptysis usually bronchial rather than pulmonary in origin?	The pulmonary circulation is low pressure, whereas the bronchial circulation is high pressure, so it is responsible for most severe cases.

IMF-077-03-0012-en	Why can a left lower-lobe cancer involve right-sided mediastinal nodes?	Lymph from lower lobes can cross to contralateral nodes, especially from left lower lung toward right superior pathways, which influences staging and spread.

IMF-077-03-0013-en	How do lobar collapse and consolidation differ radiologically?	Collapse loses volume, pulling fissures, hilum, mediastinum, diaphragm, and ribs toward the affected region, whereas consolidation fills alveoli without necessarily reducing volume and may show air bronchograms.

IMF-077-03-0014-en	How does the silhouette sign localise an opacity on a frontal radiograph?	Right heart border abuts right middle lobe, left heart border the lingula, and diaphragms the lower lobes, so loss of a border places the air-space opacity in the adjacent lobe.

IMF-078-01-0001-en	How can membranous superficial fascia direct urine or blood after selected urethral injuries, and what stops it descending into the thigh?	Membranous fascia continues into the perineum and channels the fluid along it, while its attachment to deep fascia of the thigh below the inguinal ligament limits descent into the limb.

IMF-078-01-0002-en	How does the rectus sheath differ above and below the arcuate line?	Above it, anterior and posterior laminae surround rectus; below it, all three broad-muscle aponeuroses pass anteriorly, leaving only transversalis fascia behind the muscle.

IMF-078-01-0003-en	Why can an abdominal incision denervate part of the wall?	Thoracoabdominal nerves from lower thoracic rami and first lumbar branches run segmentally between internal oblique and transversus to supply muscle and skin, so incisions crossing that plane can divide them.

IMF-078-01-0004-en	How does the anterior abdominal wall provide collateral flow between subclavian and external iliac territories?	Superior epigastric vessels continue from the internal thoracic within the rectus sheath and anastomose with inferior epigastric vessels from the external iliac.

IMF-078-01-0006-en	What trade-off distinguishes a midline linea alba incision from a transverse incision?	The linea alba is relatively avascular access but depends on durable fascial closure; transverse incisions follow skin tension and muscle planes but may cross segmental neurovascular paths.

IMF-078-01-0007-en	Why can a retroperitoneal haemorrhage or abscess produce a hip-flexion posture or femoral neuropathy?	It irritates psoas, and the lumbar plexus forms within psoas with branches emerging around it, so both the muscle and its nerves are affected.

IMF-078-01-0008-en	Why is raised intra-abdominal pressure alone an incomplete explanation for hernia formation?	Excess pressure does not itself cause every hernia; fascial weakness, anatomy, collagen, age, previous surgery, and chronic loading also contribute.

IMF-078-01-0009-en	What do reducibility, obstruction, and strangulation describe that the anatomical type of a hernia does not?	They describe the hernia's function and risk, whereas its anatomy is defined by sac, contents, neck, and coverings at a characteristic wall site.

IMF-078-01-0010-en	Why is rectus diastasis not classed as a hernia, and how does its risk differ?	It is widening of the linea alba without a true fascial defect, so it alters contour and force transmission but does not create the same strangulation risk.

IMF-079-01-0006-en	Why does a pelvic-ring injury demand assessment beyond the skeleton?	Bleeding arises from cancellous bone, venous plexuses and arteries into a large potential space, and urethra, bladder, rectum, lumbosacral plexus and limb vessels share the same ring.

IMF-079-02-0001-en	Why do the pelvic crossings of the ureter create surgical risk?	Near the cervix the ureter passes inferior to the uterine artery, and before the bladder it passes inferior to the ductus deferens, so work on these structures endangers it.

IMF-081-02-0005-en	Why does a trochlear nuclear lesion affect the contralateral superior oblique, whereas a trochlear nerve lesion affects the ipsilateral one?	Trochlear fibres decussate before exiting dorsally, so the nucleus serves the opposite eye while the nerve beyond the crossing serves its own side.

IMF-082-01-0009-en	How does the unfolded-protein response try to restore endoplasmic-reticulum homeostasis, and what happens if it cannot?	Sensors reduce general translation, increase chaperone and degradation capacity, and expand the endoplasmic reticulum; if homeostasis is not restored, prolonged signalling promotes inflammation or apoptosis.

IMF-082-01-0010-en	Why are plasma cells, pancreatic acinar cells, and hepatocytes especially dependent on the unfolded-protein response?	They are secretory cells with extensive rough endoplasmic reticulum, the compartment where secreted proteins fold, so they depend strongly on this response.

IMF-082-01-0012-en	How are soluble lysosomal enzymes directed to lysosomes, and what happens when this targeting fails?	Mannose-six-phosphate labels them and receptor-mediated sorting captures them for delivery to endosomal compartments; defective targeting lets the enzymes be secreted while undegraded substrates accumulate inside cells.

IMF-082-01-0014-en	How does the mildly acidic early endosome allow receptors to be reused, and what is the alternative fate?	Proton-pump-driven acidification can separate ligands from receptors, so receptors can recycle to restore responsiveness; alternatively they pass to lysosomes, and their degradation limits signalling.

IMF-082-01-0016-en	What gives the ubiquitin-proteasome system its specificity, and how does it connect to antigen presentation?	Tightly regulated ubiquitin ligases select substrates for polyubiquitin tagging and degradation; the resulting peptides can enter the major histocompatibility complex class one antigen-presentation pathway.

IMF-082-01-0017-en	Why does proteasomal degradation matter for cell signalling and the cell cycle, not only for disposal of abnormal proteins?	It controls the levels of short-lived signalling proteins, cell-cycle regulators, and transcription factors, so regulated destruction shapes signalling and cycle progression.

IMF-082-01-0018-en	How does the structure of the inner mitochondrial membrane enable adenosine triphosphate synthesis?	The highly selective inner membrane, folded into cristae, lets respiratory complexes pump protons across it, and adenosine triphosphate synthase uses the resulting electrochemical gradient.

IMF-082-01-0019-en	Why do mitochondria depend on protein import despite having their own genome?	Most mitochondrial proteins are nuclear encoded and synthesised in cytosol, so they must be imported through translocases using targeting sequences.

IMF-082-01-0020-en	Why do mutations in mitochondrial fusion and fission particularly affect brain, nerve, muscle, heart, and retina?	Fusion shares contents and fission supports distribution and removal of damaged regions, so defects hit tissues with high energy demand hardest.

IMF-082-01-0022-en	How do membrane contact sites correct the idea that organelles are isolated bags?	Closely apposed membranes exchange lipids, calcium, and signals without fusion; endoplasmic-reticulum contacts with mitochondria influence metabolism, mitochondrial division, and apoptosis.

IMF-082-01-0024-en	What determines whether cellular quality control ends in adaptation or in cell injury?	Integrated quality-control systems distinguish repairable damage from irrecoverable dysfunction; successful compensation yields adaptation, while failure leads to senescence, inflammatory signalling, apoptosis, or necrotic injury.

IMF-082-02-0002-en	What drives microtubule catastrophe, and why is dynamic instability useful to the cell?	Guanosine-triphosphate-bound tubulin supports growth, loss of the stabilising cap triggers rapid catastrophe, and rescue restores growth; this cycling lets plus ends search for chromosomes, cortex, organelles, and adhesion sites.

IMF-082-02-0012-en	Why can loss of epithelial polarity impair tissue function even before gross destruction?	Vectorial transport in kidney tubules and intestine works only when channels and carriers sit on the correct apical or basolateral side, so polarity loss, an early feature of dysplasia, disrupts function early.

IMF-082-03-0009-en	Why can cellular senescence be beneficial acutely yet harmful when chronic?	Senescent cells stay metabolically active and release cytokines, proteases, and growth factors; acutely this can constrain tumours and aid wound repair, but chronic accumulation drives inflammation, fibrosis, and ageing.

IMF-082-03-0010-en	Why is telomere length not a simple biological clock?	Although incomplete lagging-strand replication shortens telomeres, length is also influenced by inheritance, cell history, stress, and measurement method, and telomerase extends telomeres in germ cells and many stem cells.

IMF-082-03-0011-en	Why should experimenters not equate every dying cell with apoptosis?	Necrotic death can be regulated through necroptosis, pyroptosis, or ferroptosis with distinct machinery, and autophagy may accompany death without causing it, so morphology, markers, and mechanism must be distinguished.

IMF-082-03-0012-en	Why does colocalisation of two labelled molecules under a light microscope not prove that they interact?	Light-microscope resolution cannot establish direct molecular interaction, so claims need controls such as positive and negative samples, omitted primary antibody, matched acquisition settings, and independent validation.

IMF-082-03-0013-en	Why can DNA-content flow cytometry not alone separate gap two from mitosis, and what marker helps?	DNA content distinguishes gap one, synthesis, and gap two or mitotic populations but groups the last two together; phosphorylation of histone H three can mark mitosis.

IMF-082-03-0014-en	Why does rescue with a perturbation-resistant construct strengthen a loss-of-function experiment?	Inhibitors, RNA interference, gene editing, and targeted degradation all have off-target effects and compensatory responses; restoring the phenotype with a resistant construct ties the effect to the intended target.

IMF-083-01-0001-en	Why must a histological section not be read as if it were the tissue itself?	It is a thin, processed sample seen in one plane, stain and magnification, so interpretation must first identify artefacts and orientation before relating cells, matrix, lumina, vessels and stroma.

IMF-083-01-0007-en	Why does increasing magnification beyond the available resolution reveal no further detail?	Resolution, set by numerical aperture and wavelength, determines whether close points can be distinguished; magnification beyond it merely produces a larger blur.

IMF-083-01-0008-en	Why can the same tubular gland appear circular, oval, elongated or even solid on a slide?	Sectioning converts three-dimensional structures into two-dimensional profiles, so the plane of cut sets the outline, and a plane that misses the lumen makes the gland look solid.

IMF-083-01-0009-en	How can preparation artefacts imitate pathology, and what helps separate them from real biology?	Shrinkage creates spaces, folds mimic thickening, crushed cells look hyperchromatic and pigment or precipitate imitates deposits; relationships that stay consistent across the section indicate biology.

IMF-085-01-0012-en	What does sperm-oocyte membrane fusion set off in the oocyte?	Calcium oscillations that drive completion of meiosis two, metabolic activation, and mechanisms that prevent polyspermy.

IMF-085-01-0013-en	How does the cortical reaction prevent polyspermy, and why must polyspermy be prevented?	Granule contents released beneath the oocyte membrane modify the zona pellucida so further sperm cannot productively enter; extra sperm genomes would disrupt chromosome balance and spindle organisation.

IMF-085-01-0014-en	How do the maternal and paternal genomes come together after fertilisation, given that intact nuclei do not conventionally fuse?	Each pronucleus forms, replicates its DNA and approaches the other, and their chromosomes align together on the first mitotic spindle.

IMF-085-01-0015-en	Why does successful fertilisation not guarantee a clinically recognised pregnancy?	Many conceptions fail before clinical recognition because of chromosome or developmental abnormalities, even though fertilisation restored diploidy and started cleavage.

IMF-085-01-0016-en	How do compaction and cell position lead to the two lineages of the blastocyst, and what does each form?	Compaction at about the eight-cell stage creates inner versus outer differences, so polarity and position bias cells: outer trophectoderm forms mainly placenta and extraembryonic tissue, inner cell mass forms the embryo proper.

IMF-085-01-0017-en	How does the zona pellucida both protect normal implantation and relate to ectopic pregnancy?	It prevents premature adhesion during tubal transport and must be shed by hatching before contact with endometrium; if transport is delayed or the tube is impaired, implantation can occur outside the uterus, most often in the tube.

IMF-085-01-0018-en	What changes make the endometrium receptive to the blastocyst?	During a limited progesterone-dependent window in the secretory phase, stromal cells decidualise, enlarging, storing glycogen and lipid, and changing immune and vascular signalling.

IMF-085-01-0019-en	What distinguishes the roles of syncytiotrophoblast and cytotrophoblast during implantation?	Multinucleated syncytiotrophoblast invades epithelium and stroma without cell boundaries, eroding maternal capillaries and glands; mononuclear cytotrophoblast remains the proliferative source of new trophoblast.

IMF-085-01-0020-en	Why is human chorionic gonadotropin essential in early pregnancy, and why are its trends more useful than one value?	It rescues the corpus luteum to maintain progesterone until the placenta makes enough steroid; its level varies widely, so trends with ultrasound context are more informative than a single value.

IMF-085-01-0021-en	Why must trophoblast invasion be controlled rather than maximal?	Insufficient remodelling of maternal vessels contributes to placental insufficiency and hypertensive disorders, whereas excessive invasion can penetrate abnormally deep into the uterine wall.

IMF-085-01-0022-en	What distinguishes the fates of epiblast and hypoblast in the bilaminar disc?	Columnar epiblast next to the amniotic cavity generates all three embryonic germ layers, whereas cuboidal hypoblast contributes to yolk-sac lining rather than the embryo proper.

IMF-085-01-0023-en	How does formation of the chorionic cavity split extraembryonic mesoderm, and what keeps the embryo attached?	Coalescing cavities separate somatic mesoderm lining trophoblast and amnion from splanchnic mesoderm covering yolk sac; the connecting stalk links embryo to chorionic wall and later contributes to the umbilical cord.

IMF-085-01-0024-en	Why does preimplantation genetic testing not guarantee implantation or a healthy child?	It samples trophectoderm cells and yields only selected genetic information, while culture conditions, embryo selection, transfer number, parental age and underlying infertility also shape outcome.

IMF-085-02-0001-en	Why do all tissues of the embryo proper derive from epiblast?	Epiblast cells ingress through the primitive streak: the first displace hypoblast to form definitive endoderm, later ones spread as intraembryonic mesoderm, and those remaining at the surface become ectoderm.

IMF-085-02-0002-en	What cell-state change allows epiblast cells to pass inward at the primitive streak?	They loosen epithelial attachments and convert to a motile mesenchymal state, which lets them migrate between layers.

IMF-085-02-0003-en	Beyond marking the midline, what does the notochord do, and where does it persist in the adult?	It defines the primitive axis, patterns surrounding tissues and induces neural development; it degenerates within vertebral bodies but persists between them, mainly as nucleus pulposus.

IMF-085-02-0004-en	What is structurally special about the oropharyngeal and cloacal membranes, and what do they mark?	Ectoderm and endoderm are directly apposed there with no intervening mesoderm; they mark future openings of the oral cavity and of the terminal gut or urogenital pathways.	Integrated Medical Foundations; chapter 85, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 1ed6e9281a72d468fff7a576dabf411ed0cf4a6f8d51c67fe9584a4a4b3f5993; editorial review pending	imf lang::en chapter::085 module::085-02 review::pending
IMF-085-02-0005-en	How can persistence of primitive-streak cells cause a tumour containing several tissue types?	The streak cells are pluripotent, so if they persist they can form a sacrococcygeal teratoma with derivatives of multiple germ layers.

IMF-085-02-0006-en	What do liver and pancreas illustrate about germ-layer origins of mature organs?	Endoderm forms their parenchymal epithelium, while mesoderm supplies much of their connective tissue, vessels and muscle, so mature organs combine lineages.

IMF-085-02-0007-en	How does the notochord induce neural plate from overlying ectoderm?	Notochord and organiser signals inhibit pathways that would otherwise favour surface ectoderm, so the overlying ectoderm thickens into neural plate.

IMF-085-02-0008-en	Why does periconceptional folate reduce neural-tube defect risk, and why does it not prevent every case?	Folate supports one-carbon metabolism and nucleotide synthesis during rapid growth, but genetic susceptibility, maternal diabetes, medications, hyperthermia and other exposures also modify risk.

IMF-085-02-0009-en	How is the neural tube divided into sensory and motor regions?	Gradients including sonic hedgehog from notochord and floor plate pattern dorsal alar regions for sensory processing and ventral basal regions for motor function, separated by the sulcus limitans.

IMF-085-02-0010-en	Why can a single neural crest defect combine pigmentation, craniofacial, cardiac and intestinal abnormalities?	Neural crest cells migrate widely and generate melanocytes, craniofacial cartilage and bone, conotruncal cardiac septation and the enteric nervous system, so a migration or differentiation defect affects all of them.	Integrated Medical Foundations; chapter 85, TTS module 2; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 1ed6e9281a72d468fff7a576dabf411ed0cf4a6f8d51c67fe9584a4a4b3f5993; editorial review pending	imf lang::en chapter::085 module::085-02 review::pending
IMF-085-02-0011-en	How does resegmentation of sclerotomes explain why spinal nerves exit between vertebrae?	Each vertebral body forms from the caudal half of one sclerotome joined to the cranial half of the next, so segmental nerves come to lie between vertebrae and myotomes bridge adjacent levels to move the column.

IMF-085-02-0012-en	What distinguishes somatopleure from splanchnopleure in composition and derivatives?	Somatopleure is somatic mesoderm plus ectoderm and forms body wall and limbs; splanchnopleure is splanchnic mesoderm plus endoderm and forms gut wall, visceral connective tissue and heart.

IMF-085-02-0013-en	Why can ciliary dysfunction combine laterality defects with respiratory disease?	Motile nodal cilia generate directional fluid flow that contributes to left-sided signalling at the primitive node, so the same ciliary defect can disturb left-right patterning and also cause respiratory disease.

IMF-085-02-0014-en	What drives embryonic folding in the fourth week, and how does cranial folding reposition the heart?	Rapid growth of neural tube and somites drives folding; cranial folding moves the cardiogenic region and septum transversum from a cranial position to the ventral thorax and upper abdomen, ventral to the foregut.

IMF-085-03-0001-en	What change marks each step from primary to secondary to tertiary chorionic villi?	Primary villi are cytotrophoblast columns within syncytiotrophoblast; extraembryonic mesoderm entering the core makes secondary villi; fetal capillaries developing in the core make tertiary villi.

IMF-085-03-0004-en	How do glucose, amino acids and immunoglobulin G cross the placenta differently from gases?	Gases diffuse, whereas glucose uses facilitated transport, amino acids use active or carrier-mediated transport, and immunoglobulin G crosses by receptor-mediated transcytosis.

IMF-085-03-0005-en	Why does spiral artery remodelling matter, and what follows when it is incomplete?	Extravillous trophoblast converts narrow muscular responsive arteries into wide low-resistance channels that sustain high-volume flow; incomplete remodelling is associated with hypoperfusion, fetal growth restriction and pre-eclampsia.

IMF-085-03-0013-en	Why is chorionicity clinically more important than zygosity in twins?	A shared placenta has vascular connections between the twins, creating risks such as twin-to-twin transfusion, selective growth restriction and consequences when one twin dies.

IMF-085-03-0014-en	Why can the same teratogenic exposure cause loss, malformation or no detectable effect?	Outcome depends on dose, timing, duration, route, maternal metabolism, placental transfer and embryonic genotype, and vulnerability shifts with stage, weeks three to eight carrying high susceptibility to structural malformation.

IMF-086-01-0001-en	How does the primitive heart tube form from cardiogenic mesoderm, and what separates its layers?	Embryonic folding brings the paired heart-forming regions ventrally and together, where endothelial tubes fuse; surrounding splanchnic mesoderm forms myocardium, separated from endocardium by cardiac jelly.

IMF-086-01-0002-en	Why must a congenital heart be described by tracing its connections rather than by chamber position alone?	Looping sets spatial relationships but does not complete chamber identity, and abnormal looping can give discordant atrioventricular or ventriculoarterial connections, so venous return and each connection must be traced.

IMF-086-01-0003-en	Why does the right horn of the sinus venosus become part of the right atrium while the left horn becomes the coronary sinus?	Shunting of venous return toward the right enlarges the right horn into the smooth sinus venarum, while the left horn becomes the coronary sinus and oblique vein; the crista terminalis marks the smooth-trabeculated junction.

IMF-086-01-0004-en	Why is the posterior wall of the left atrium smooth, and what happens when this process goes wrong?	Pulmonary veins are progressively incorporated into the posterior left atrium, forming its smooth wall; abnormal connection leaves them draining partly or entirely into systemic veins, with presentation set by obstruction and mixing.

IMF-086-01-0005-en	How does the fetal atrial septum permit right-to-left flow while restricting reverse flow?	Septum secundum forms to the right, leaving the foramen ovale, and septum primum acts as a flap valve that permits fetal right-to-left flow but restricts flow in the opposite direction.	Integrated Medical Foundations; chapter 86, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 9ca814733ca5a2512b145fbaca156694132985022cc9035fd6e0035cbb850763; editorial review pending	imf lang::en chapter::086 module::086-01 review::pending
IMF-086-01-0006-en	Why does the foramen ovale close functionally after birth?	Increased pulmonary blood flow raises left-atrial pressure, which presses septum primum against septum secundum and closes the foramen; anatomical fusion may follow later.

IMF-086-01-0007-en	What distinguishes a probe-patent foramen ovale from a true atrial septal defect?	A probe-patent foramen ovale reflects incomplete anatomical fusion after functional closure, whereas a true atrial septal defect reflects deficient tissue and permits sustained shunting.

IMF-086-01-0008-en	Why can an endocardial cushion defect combine atrial and ventricular septal defects with abnormal atrioventricular valves?	The cushions divide the atrioventricular canal and contribute valve leaflets, the membranous ventricular septum and atrial septal closure, so a failure of cushion formation affects all of these together.	Integrated Medical Foundations; chapter 86, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 9ca814733ca5a2512b145fbaca156694132985022cc9035fd6e0035cbb850763; editorial review pending	imf lang::en chapter::086 module::086-01 review::pending
IMF-086-01-0009-en	Where do ventricular septal defects most often occur, and why can a large one eventually reverse its shunt?	Most involve the membranous region, derived from cushions and outflow ridges; prolonged large left-to-right shunting causes pulmonary vascular disease that can eventually reverse the shunt.

IMF-086-01-0010-en	Why do defects of neural-crest migration produce conotruncal anomalies?	Neural crest populates the outflow ridges that spiral and fuse into the aorticopulmonary septum, so migration or rotation defects leave great arteries unseparated or misaligned, as in persistent truncus or tetralogy of Fallot.	Integrated Medical Foundations; chapter 86, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 9ca814733ca5a2512b145fbaca156694132985022cc9035fd6e0035cbb850763; editorial review pending	imf lang::en chapter::086 module::086-01 review::pending
IMF-086-01-0011-en	How does a single developmental error produce all four features of tetralogy of Fallot?	Anterior displacement of the outflow septum creates right-ventricular outflow obstruction, a ventricular septal defect and an overriding aorta, with secondary right-ventricular hypertrophy; severity depends mainly on obstruction and shunt.	Integrated Medical Foundations; chapter 86, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 9ca814733ca5a2512b145fbaca156694132985022cc9035fd6e0035cbb850763; editorial review pending	imf lang::en chapter::086 module::086-01 review::pending
IMF-086-01-0012-en	Why does survival in complete transposition of the great arteries depend on an atrial, ventricular or ductal communication?	Failure of normal outflow spiralling creates parallel systemic and pulmonary circuits, so the two circulations meet only where blood can mix through such a communication.

IMF-086-01-0013-en	Why may a congenital valve abnormality become clinically important only years after birth?	Abnormal cusp number, fusion or matrix is structurally present at birth, but the resulting stenosis or regurgitation may become clinically important only after years of altered stress.

IMF-086-01-0014-en	How does asymmetric aortic arch remodelling account for the carotid, aortic arch, right subclavian, pulmonary arteries and ductus arteriosus?	Third arches form common and proximal internal carotids; left fourth forms part of the aortic arch and right fourth the proximal right subclavian; sixth arches form proximal pulmonary arteries, the left distal sixth persisting as the ductus.

IMF-086-01-0015-en	How can abnormal persistence of aortic arch segments compress the airway and oesophagus?	A double aortic arch, or a right arch with ligamentous components, can form a vascular ring around the trachea and oesophagus; an aberrant subclavian artery passing behind the oesophagus may occasionally impair swallowing.

IMF-086-01-0016-en	How does embryonic venous remodelling explain variants such as a left-sided superior vena cava or anomalous renal veins?	Cardinal systems form the major systemic veins through selective anastomosis and regression, so variations in this complex remodelling leave a left superior vena cava, anomalous renal veins or collateral pathways.

IMF-086-01-0017-en	Which anomalous coronary origins or courses particularly compromise perfusion, and what developmental step do they reflect?	An artery passing between the great vessels or arising from the pulmonary artery; they reflect failure of the proximal coronary stems to enter the appropriate aortic root sinuses.

IMF-086-01-0018-en	How does incomplete tracheoesophageal partition present before and after birth?	Incomplete separation by the tracheoesophageal folds commonly gives oesophageal atresia with distal fistula, causing polyhydramnios prenatally and choking, respiratory distress or gastric distension after birth.

IMF-086-01-0020-en	Which lung tissues derive from endoderm and which from splanchnic mesoderm, and what drives repeated branching?	Epithelium and glands are endodermal, while smooth muscle, cartilage, connective tissue and vessels are splanchnic mesoderm; reciprocal epithelial-mesenchymal signalling guides repeated branching.

IMF-086-01-0021-en	What distinguishes the pseudoglandular stage from the canalicular stage of lung development?	In the pseudoglandular stage conducting airways branch but gas-exchange structures are absent; the canalicular stage enlarges lumina, increases vascularisation and begins respiratory bronchioles.

IMF-086-01-0022-en	Why does surfactant deficiency in prematurity cause respiratory distress, and how can maturation be accelerated?	Inadequate surfactant from type two pneumocytes raises surface tension, causing atelectasis and low compliance; antenatal glucocorticoids accelerate maturation when preterm birth is likely.

IMF-086-01-0023-en	Why can severe oligohydramnios or absent fetal urine cause pulmonary hypoplasia?	Fetal lung fluid maintains expansion and supports growth, so conditions that impair expansion, including oligohydramnios, prolonged membrane rupture or absent fetal urine, limit lung growth.

IMF-086-01-0024-en	In congenital diaphragmatic hernia, why does clinical severity reflect lung development more than the defect itself?	Abdominal viscera herniating through the posterolateral defect compress the developing lung, causing hypoplasia and pulmonary hypertension, and these, not the hole, determine severity.

IMF-086-02-0002-en	How does duodenal atresia arise, and why does the level of obstruction relative to the bile-duct opening matter?	The duodenal epithelium temporarily occludes the lumen, and failed recanalisation produces stenosis or atresia; obstruction proximal or distal to the bile-duct opening changes the character of vomiting.

IMF-086-03-0002-en	Why do brainstem cranial sensory nuclei lie lateral to motor nuclei, unlike the spinal cord's dorsal-ventral arrangement?	In the hindbrain, the pontine flexure opens the roof of the fourth ventricle and displaces the alar plates laterally to the basal plates, so sensory derivatives lie lateral to motor ones.

IMF-086-03-0005-en	What fusion failure causes cleft lip, and why can the cleft extend into the primary palate?	Cleft lip results when the maxillary prominence fails to fuse with the medial nasal prominence; because that fusion forms both the upper lip and the primary palate, the cleft may extend through the primary palate.

IMF-086-03-0006-en	Why can cleft palate arise from many different failures, with or without cleft lip?	The secondary palate requires palatal shelves to grow, elevate from vertical beside the tongue to horizontal, contact, adhere and fuse, so failure at any of these steps leaves a cleft.

IMF-086-03-0008-en	Why does a thyroglossal duct cyst lie in the midline and move with swallowing or tongue protrusion?	The thyroid descends from near the foramen caecum through the thyroglossal duct to the anterior neck; remnants of this midline tract form the cyst, and thyroid tissue can remain ectopic along the route.

IMF-086-03-0011-en	Why can an external ear anomaly be a clue to renal, cardiac or mandibular conditions, and when is it reassuring?	The ear shares pharyngeal-arch and neural-crest development with other structures, so its anomalies can signal renal, cardiac, mandibular or chromosomal conditions, but an isolated minor variant is often benign.

IMF-087-02-0001-en	Why can a single amino-acid substitution have effects ranging from none to a toxic new function?	One substitution can change charge, packing, cleavage, stability, trafficking, or assembly, and its effect depends on position and environment.

IMF-087-02-0007-en	How does reaction order in substrate change between low and very high substrate concentrations?	Far below the Michaelis constant, velocity is roughly proportional to substrate (first order); far above it, velocity nears maximum and is roughly zero order, yet still proportional to enzyme.

IMF-088-01-0014-en	Why does acetyl coenzyme A activate pyruvate carboxylase, and how does the oxaloacetate formed reach the gluconeogenic pathway?	Acetyl coenzyme A signals abundant fatty-acid oxidation; oxaloacetate cannot cross the inner membrane, so it leaves as malate or aspartate or is converted to phosphoenolpyruvate in mitochondria.

IMF-088-01-0015-en	How does phosphoenolpyruvate carboxykinase make the difficult reversal of pyruvate kinase feasible?	It uses guanosine triphosphate to decarboxylate and phosphorylate oxaloacetate, and the decarboxylation helps drive formation of phosphoenolpyruvate.

IMF-088-01-0021-en	What does the glucose–alanine cycle carry that the Cori cycle does not, and why do neither create free energy?	It moves amino nitrogen as well as carbon, which liver turns into urea; both cycles merely redistribute burden, as liver spends energy to make glucose.

IMF-088-02-0001-en	How do the outer and inner mitochondrial membranes differ, and what do cristae add?	The outer membrane passes many small solutes through porins, the inner is highly selective, and cristae increase area and organise respiratory supercomplexes and adenosine-triphosphate synthase.

IMF-088-02-0002-en	How is mitochondrial NAD-dependent isocitrate dehydrogenase regulated, and why does this suit energy supply?	Adenosine diphosphate and calcium activate it and high adenosine triphosphate and NADH inhibit it, so cycle flux rises with energy use and falls with energy abundance.

IMF-088-02-0006-en	Why can citric-acid-cycle flux fail even when acetyl coenzyme A is abundant?	Intermediates are withdrawn for biosynthesis (cataplerosis); unless replenished by anaplerosis such as pyruvate carboxylation, depleted intermediates limit the cycle.

IMF-088-02-0007-en	Why does lack of oxygen slow the citric-acid cycle and increase lactate production?	Without the terminal acceptor, upstream carriers stay reduced, NADH cannot be oxidised, cycle flux slows, and cells rely on glycolytic lactate production.

IMF-088-02-0008-en	Why does oxygen consumption reflect cellular energy demand and not only substrate supply?	When adenosine diphosphate is scarce the proton gradient rises and respiration slows; when work consumes adenosine triphosphate, returning adenosine diphosphate lets synthase conduct protons and electron transport accelerates.

IMF-088-03-0014-en	Why must a metabolite concentration be distinguished from pathway flux in clinical interpretation?	A concentration can stay normal when production and consumption both accelerate, and an accumulated intermediate may reflect either increased formation or blocked disposal.

IMF-089-01-0001-en	Why can failure of fat mobilisation or mitochondrial entry cause an energy crisis even when stored fat is abundant?	Fatty-acid oxidation is a key fuel during fasting and sustained exercise, and stored fat helps only if it is mobilised and enters mitochondria to be oxidised.

IMF-089-01-0002-en	Why do lingual and gastric lipases matter mainly in infants or pancreatic insufficiency?	Most lipid digestion normally occurs in small intestine, where bile salts emulsify fat into small droplets and pancreatic enzymes hydrolyse ester bonds, so the earlier lipases otherwise contribute only modestly.

IMF-089-01-0003-en	How do lipids and bile salts in mixed micelles behave differently at the enterocyte brush border?	Micelles carry digestion products through the unstirred aqueous layer; lipids leave them to enter cells, while bile salts stay in the lumen until distal reabsorption in terminal ileum for portal recycling.

IMF-089-01-0004-en	How does the enterocyte repackage absorbed long-chain lipid for export?	Long-chain fatty acids and monoacylglycerols are re-esterified to triacylglycerol in endoplasmic reticulum, cholesterol is partly esterified, and microsomal triglyceride-transfer protein loads lipid onto apolipoprotein B-48 to form chylomicrons.

IMF-089-01-0005-en	Why do chylomicrons initially bypass the liver, whereas short- and medium-chain fatty acids do not?	Chylomicrons leave through lymphatic lacteals and the thoracic duct into systemic blood, whereas short- and medium-chain fatty acids are more water soluble and travel directly in portal blood bound to albumin.

IMF-089-01-0006-en	Why do pancreatic failure, deficient bile, ileal disease and lymphatic obstruction share a common clinical consequence?	Each disrupts a required step in lipid digestion, solubilisation, bile recycling or chylomicron export, so all cause fat malabsorption with fat-soluble-vitamin deficiency.

IMF-089-01-0007-en	How does insulin steer chylomicron fatty acids toward adipose tissue after a meal?	Lipoprotein lipase on capillary endothelium hydrolyses chylomicron triacylglycerol for local uptake; insulin favours adipose lipoprotein-lipase activity after meals, while muscle takes fatty acids according to demand.

IMF-089-01-0008-en	What switches adipose lipolysis on during fasting or exercise, and what switches it off?	Catecholamines and low insulin activate adipose triglyceride lipase and hormone-sensitive lipase through signalling and droplet remodelling; insulin suppresses lipolysis and promotes re-esterification.

IMF-089-01-0009-en	Why is plasma non-esterified fatty acid a measure of flux rather than stores, and why does its level matter?	It reflects rapid flux, not the much larger stored pool; excessive release contributes to hepatic lipid accumulation and insulin resistance, while inadequate release limits fasting fuel.

IMF-089-01-0010-en	Why is activating a fatty acid to acyl coenzyme A worth two high-energy phosphate equivalents?	Acyl-CoA synthetase converts ATP to AMP and pyrophosphate, and the resulting fatty acyl-CoA traps the fatty acid for oxidation, esterification, elongation or signalling.

IMF-089-01-0011-en	Why does long-chain fatty acyl-CoA need carnitine to reach the mitochondrial matrix, and how does it cross?	It cannot cross the inner membrane; CPT1 on the outer membrane moves the acyl group to carnitine, a translocase swaps acylcarnitine in for free carnitine out, and CPT2 regenerates acyl-CoA in the matrix.

IMF-089-01-0012-en	How does malonyl-CoA prevent fatty-acid synthesis and oxidation running at once, and how is the brake released in fasting?	Malonyl-CoA, made by acetyl-CoA carboxylase in the fed state, inhibits CPT1; in fasting or exercise AMP-activated kinase inhibits the carboxylase, malonyl-CoA falls, and oxidation rises.

IMF-089-01-0013-en	In one beta-oxidation cycle, which steps generate reduced cofactors and which releases acetyl-CoA?	The first dehydrogenation passes electrons via FAD to electron-transfer flavoprotein, hydration adds water, the second dehydrogenation makes NADH, and thiolysis with CoA releases acetyl-CoA and a chain two carbons shorter.

IMF-089-01-0014-en	What does complete oxidation of palmitate yield, and what does that yield depend on?	Seven cycles give eight acetyl-CoA, seven NADH and seven reduced flavin equivalents, roughly 106 ATP after activation cost, far more than glucose per molecule but only with oxygen and mitochondrial function.

IMF-089-01-0015-en	If fat yields more energy per carbon, why can carbohydrate be advantageous when oxygen delivery limits exercise?	Fatty acids are highly reduced and stored without water, giving a high yield per carbon, but their oxidation consumes more oxygen per ATP than carbohydrate.

IMF-089-01-0016-en	Why do odd-chain fatty acids provide limited net glucogenic carbon?	Their final propionyl-CoA is carboxylated by a biotin-dependent enzyme to methylmalonyl-CoA and converted by a vitamin B12-dependent mutase to succinyl-CoA, which replenishes cycle intermediates and can feed gluconeogenesis.

IMF-089-01-0017-en	Why does the first step of peroxisomal very-long-chain fatty-acid oxidation yield no respiratory energy?	It transfers electrons directly to oxygen, producing hydrogen peroxide that catalase removes; the shortened chains are then passed to mitochondria for completion.

IMF-089-01-0018-en	Why must phytanic acid undergo alpha oxidation, and what happens when this fails?	Its methyl group blocks conventional beta oxidation, so it is handled by peroxisomal alpha oxidation; defects cause accumulation affecting retina, peripheral nerves, cerebellum, skin, hearing and heart.

IMF-089-01-0019-en	What does newborn screening for medium-chain acyl-CoA dehydrogenase deficiency make possible, and why does it matter?	The defect impairs oxidation during fasting or illness, causing hypoketotic hypoglycaemia, lethargy, seizures and liver dysfunction, so early detection permits preventive avoidance of prolonged fasting.

IMF-089-01-0020-en	Why can primary carnitine deficiency cause cardiomyopathy and hypoketotic hypoglycaemia?	It impairs tissue carnitine uptake, so long-chain acyl groups cannot be carried into mitochondria for oxidation, producing low plasma carnitine, cardiomyopathy, weakness and hypoketotic hypoglycaemia.

IMF-089-01-0021-en	Why does failed fatty-acid oxidation cause hypoglycaemia with inappropriately low ketones?	Hepatic oxidation normally powers gluconeogenesis, and its acetyl-CoA activates pyruvate carboxylase and inhibits pyruvate dehydrogenase; without it gluconeogenesis loses energy and activation while peripheral glucose use continues.

IMF-089-01-0022-en	How does training let muscle preserve glycogen at a given workload?	Training increases mitochondrial density, capillaries, transport proteins and the capacity to oxidise fat, so more of the fuel at that workload comes from fatty acids.

IMF-089-01-0023-en	Why does abundant intramyocellular lipid in endurance-trained muscle not by itself imply insulin resistance?	Trained muscle can hold substantial lipid while staying insulin sensitive, because toxicity relates to mismatched supply and disposal accumulating diacylglycerols, ceramides or incompletely oxidised products, not neutral triacylglycerol quantity.

IMF-089-01-0024-en	Why does diagnosis of a suspected block in lipid fuel supply combine timing, ketones and specialised tests?	A block at any boundary, from intestinal absorption to mitochondrial enzymes, can resemble fuel scarcity, so timing with fasting or exercise, ketones, glucose, lactate, ammonia, acylcarnitines, organic acids, enzymes and genetics are used together.

IMF-089-02-0001-en	How does acetyl-CoA reach the cytosol for fatty-acid synthesis, and how does that route also supply NADPH?	When energy and carbon are abundant it is exported as citrate, which ATP-citrate lyase cleaves to acetyl-CoA and oxaloacetate; oxaloacetate returns via malate and pyruvate, with malic enzyme generating extra NADPH.

IMF-089-02-0003-en	Why are linoleic and alpha-linolenic acids essential, and why does dietary intake of long-chain forms still matter?	Humans insert double bonds only at selected positions and cannot make them; conversion to longer omega-6 and omega-3 forms is limited and competes for enzymes, so dietary long-chain forms shape membranes and mediators.

IMF-089-02-0014-en	Why can choline deficiency contribute to fatty liver?	Steatosis arises when fatty-acid uptake and synthesis exceed oxidation and export, and choline deficiency impairs phosphatidylcholine and lipoprotein export.

IMF-089-03-0001-en	How is blood glucose maintained early in an overnight fast while glucose is also spared?	Liver glycogen supplies much glucose as gluconeogenesis rises; falling insulin and rising glucagon permit lipolysis, so muscle and liver oxidise more fat, while glycerol, lactate and alanine feed gluconeogenesis.

IMF-089-03-0002-en	Why does rising ketone availability protect muscle protein during prolonged fasting?	Ketones let the brain reduce glucose use, lowering the need to convert muscle protein into glucose, since sustained protein loss would be incompatible with survival.

IMF-089-03-0003-en	Why does hepatic ketogenesis accelerate when fatty-acid oxidation is high?	Oxaloacetate is diverted to gluconeogenesis and high NADH slows cycle reactions, so acetyl-CoA exceeds citric-acid-cycle capacity and is routed via HMG-CoA synthase and lyase to acetoacetate.

IMF-089-03-0004-en	Why does the liver export ketone bodies but cannot use them?	It lacks succinyl-CoA:acetoacetate CoA-transferase (thiophorase), which extrahepatic mitochondria use to activate acetoacetate with succinyl-CoA before splitting it into two acetyl units for oxidation.

IMF-089-03-0005-en	What distinguishes physiological nutritional ketosis from ketoacidosis?	In nutritional ketosis, preserved insulin restrains runaway lipolysis so ketonaemia stays limited and pH is regulated; ketoacidosis arises when production overwhelms utilisation and buffering amid hormonal dysregulation.

IMF-089-03-0006-en	How does severe insulin deficiency drive ketogenesis in diabetic ketoacidosis?	With excess glucagon and stress hormones, adipose lipolysis floods the liver with fatty acids, malonyl-CoA falls, and mitochondrial fatty-acid entry and ketogenesis accelerate.

IMF-089-03-0007-en	Why is total-body potassium depleted in diabetic ketoacidosis even when serum potassium is normal or high?	Osmotic diuresis causes electrolyte loss, while insulin deficiency, acidosis and hyperosmolality shift potassium out of cells, so the serum value hides the depletion.

IMF-089-03-0008-en	Why is glucose added during treatment of diabetic ketoacidosis once blood glucose falls?	Insulin is given to stop ketogenesis, and ketones are still being cleared after glucose falls, so glucose is added to let insulin continue.

IMF-089-03-0009-en	Why does alcoholic ketoacidosis favour beta-hydroxybutyrate, and why is dextrose given with thiamine?	Ethanol-induced high NADH, with low glycogen, low insulin and lipolysis, favours beta-hydroxybutyrate; dextrose stimulates insulin, and thiamine is given before or with carbohydrate in at-risk patients.

IMF-089-03-0010-en	Why can urine nitroprusside testing mislead both in severe ketoacidosis and during recovery?	It detects acetoacetate more than beta-hydroxybutyrate; high NADH in severe illness shifts the pool to beta-hydroxybutyrate, underestimating severity, and reconversion during recovery keeps urine ketones high despite improvement.

IMF-089-03-0011-en	Why is refeeding after severe deprivation dangerous even though food is not a toxin?	The metabolic transition triggers insulin-driven shifts of phosphate, potassium and magnesium and raises thiamine demand; severe hypophosphataemia impairs heart, respiratory muscle, blood cells and nervous system.

IMF-089-03-0012-en	How can insulin resistance worsen hepatic steatosis when insulin normally promotes lipogenesis?	Insulin resistance can increase fatty-acid delivery from adipose tissue while hepatic lipogenesis remains insulin responsive, so uptake plus synthesis exceed oxidation plus lipoprotein export.

IMF-089-03-0013-en	What distinguishes adrenoleukodystrophy from Zellweger-spectrum disorders at the peroxisome?	Adrenoleukodystrophy impairs peroxisomal transport of very-long-chain fatty acids, whereas Zellweger-spectrum disorders impair peroxisome assembly and so disrupt multiple pathways, causing severe multisystem disease.

IMF-090-01-0001-en	Why must excess amino nitrogen be transferred and excreted rather than stored?	Unlike carbohydrate and fat, amino acids have no dedicated inert storage depot, so excess amino nitrogen must be safely transferred and excreted while carbon skeletons enter other pathways.

IMF-090-01-0003-en	Why can one inherited amino-acid transporter defect affect both intestine and kidney, and how can it produce pellagra-like features?	Similar carriers serve apical epithelia in both organs; losing selected neutral amino acids can reduce tryptophan availability, producing pellagra-like or neurological manifestations.

IMF-090-01-0006-en	How does amino-acid catabolism usually begin, and what carries the amino group?	Rather than releasing free ammonia, aminotransferases move the alpha-amino group to alpha-ketoglutarate, forming glutamate and an alpha-ketoacid; pyridoxal phosphate from vitamin B6 carries the group.

IMF-090-01-0009-en	Why is ammonia carried in glutamine rather than free, and how is it released for disposal?	Free ammonia is toxic, particularly to brain, so glutamine synthetase uses ATP to join it to glutamate; liver and kidney glutaminase later release ammonia for urea synthesis or urinary buffering.

IMF-090-02-0001-en	Why does vitamin B12 deficiency impair nucleotide synthesis even when total folate is adequate?	Methionine synthase needs B12 to pass the methyl group from methyl tetrahydrofolate to homocysteine and regenerate tetrahydrofolate; without it, folate is trapped in the methyl form.

IMF-090-02-0002-en	What pathway does cystathionine beta-synthase serve, and what does its severe deficiency cause?	It combines homocysteine with serine using pyridoxal phosphate, starting transsulfuration toward cysteine; severe deficiency causes homocystinuria with thrombosis, lens dislocation, skeletal and neurological effects.

IMF-090-02-0003-en	Why is folate treatment alone hazardous in vitamin B12 deficiency?	Folate can correct the blood abnormalities, but B12 deficiency also impairs methylmalonyl-CoA mutase, raising methylmalonate, so neurological injury can progress.

IMF-090-02-0004-en	How are the hepatic and erythroid forms of delta-aminolevulinate synthase regulated differently?	The hepatic enzyme is feedback repressed by haem and induced by selected drugs and hormones, whereas erythroid synthesis is coordinated with iron availability and globin production.

IMF-090-02-0005-en	Which haem-synthesis enzymes does lead inhibit, and what is central to diagnosing lead poisoning?	Lead inhibits aminolevulinate dehydratase and ferrochelatase; basophilic stippling may occur, but no single smear feature is diagnostic, so blood lead measurement and exposure history are central.

IMF-090-02-0006-en	Why can drugs, fasting, alcohol and hormones precipitate acute attacks in porphyria?	They induce hepatic haem demand, so early precursors such as aminolevulinate and porphobilinogen accumulate behind the partial enzyme defect and cause acute neurovisceral attacks.

IMF-090-02-0007-en	Why do later haem-pathway defects cause photosensitivity while purely acute hepatic forms usually do not?	Accumulated later porphyrinogens oxidise to photosensitising porphyrins that cause light-dependent skin injury, whereas early precursors produce neurovisceral attacks instead.

IMF-090-02-0008-en	Why does unconjugated hyperbilirubinaemia not darken the urine, whereas conjugated hyperbilirubinaemia can?	Unconjugated bilirubin is hydrophobic and albumin bound, so it is not filtered into urine; hepatic conjugation makes water-soluble bilirubin diglucuronide.

IMF-090-02-0009-en	Why are newborns at risk of kernicterus, and how does phototherapy help?	Increased production, immature conjugation and enterohepatic recycling raise unconjugated bilirubin, whose unbound form crosses the immature blood-brain barrier; phototherapy converts it to more excretable isomers.

IMF-090-02-0010-en	Why do tetrahydrobiopterin defects need treatment beyond phenylalanine restriction?	The same cofactor serves tyrosine and tryptophan hydroxylation, so its loss also reduces dopamine and serotonin synthesis, requiring neurotransmitter-directed therapy.

IMF-090-02-0012-en	What happens when nitric-oxide synthase lacks adequate cofactors?	It requires tetrahydrobiopterin, flavins, haem, NADPH and oxygen; when cofactor supply is disturbed the synthase can become uncoupled and generate superoxide.

IMF-090-03-0001-en	Why can excess PRPP formation increase uric-acid production?	PRPP activates amidophosphoribosyltransferase, so excess drives de novo purine synthesis and, in turn, uric-acid production.

IMF-090-03-0003-en	How does the branching of inosine monophosphate help balance adenine and guanine nucleotide pools?	The AMP branch uses GTP and the GMP branch uses ATP, so each draws on the other's product, and end products feedback-inhibit their own branches.

IMF-090-03-0004-en	Why does a purine salvage enzyme defect cause both nucleotide shortage and excess purine degradation?	Salvage normally recycles free bases and restrains PRPP-driven de novo synthesis; when it fails, recycling is lost and purine degradation increases.

IMF-091-01-0001-en	How does origin licensing ensure that each genomic segment is normally copied only once per cell cycle?	Inactive helicases are loaded at origins in late mitosis and gap one, and in synthesis phase kinases activate a subset; activation prevents relicensing until the next cycle.

IMF-091-01-0002-en	Why does replication require primers, and what happens to them on the lagging strand?	Replicative polymerases cannot begin de novo, so primase in the polymerase-alpha complex makes short RNA-DNA primers; on the lagging strand these are removed, gaps filled, flaps processed and ligase seals the backbone.

IMF-091-01-0012-en	Why do inherited mismatch-repair defects in Lynch syndrome produce microsatellite instability?	Repetitive microsatellite sequences are especially prone to replication errors, so when mismatch repair fails these errors persist and the repeats become unstable.

IMF-091-01-0013-en	A tumour shows loss of a mismatch-repair protein on immunohistochemistry. Why does this not by itself establish Lynch syndrome?	Absent staining can result from an inherited variant, a somatic event, or epigenetic silencing, so the abnormal screen must be interpreted to distinguish them.

IMF-091-01-0014-en	How does base-excision repair remove a small non-distorting lesion such as uracil or an oxidised base?	A lesion-specific glycosylase removes the base, leaving an abasic site; an endonuclease cuts the backbone, the sugar phosphate is processed, and polymerase and ligase fill and seal.

IMF-091-01-0015-en	Why can PARP inhibition selectively kill homologous-recombination-deficient tumour cells?	Unrepaired single-strand lesions are converted into toxic replication-associated breaks that these cells cannot repair, a synthetic lethality; restored repair or fork protection can cause resistance.

IMF-091-01-0016-en	What triggers global-genome versus transcription-coupled nucleotide-excision repair?	Global-genome surveillance scans broadly for bulky helix-distorting lesions, whereas transcription-coupled repair is triggered when RNA polymerase stalls on a lesion in an active gene.

IMF-091-01-0017-en	Why do xeroderma pigmentosum and Cockayne-spectrum disease differ clinically although both involve nucleotide-excision repair?	Xeroderma pigmentosum defects cause extreme ultraviolet sensitivity and skin and eye cancers, whereas Cockayne defects impair transcription-coupled responses, causing growth and neurological disease; different regions and responses are compromised.

IMF-091-01-0018-en	Why is MGMT repair called a suicide reaction, and why does its tumour silencing matter for treatment?	MGMT transfers the alkyl group from guanine to itself and is then degraded, so each molecule acts once; tumours that silence it are more sensitive to some alkylating agents.

IMF-091-01-0019-en	Why is homologous recombination favoured in synthesis and gap-two phases, and how does it achieve accurate repair?	It needs a sister chromatid as template; ends are resected to single-stranded DNA, a RAD51 filament searches and invades the homologous sequence, and templated synthesis restores the sequence accurately.

IMF-091-01-0020-en	Why are germline BRCA status, tumour repair phenotype, and current drug sensitivity not interchangeable?	Tumours carry genomic scars recording past homologous-repair deficiency but may restore function through secondary mutations, so historical deficiency need not mean current sensitivity.

IMF-091-01-0021-en	What distinguishes classical non-homologous end joining from homologous recombination in timing, use and cost?	It ligates broken ends without a long homologous template, works throughout the cycle and is essential for antigen-receptor rearrangement, but can leave small insertions or deletions.

IMF-091-01-0022-en	Why does the Fanconi phenotype depend on more than the missing repair activity?	Interstrand-crosslink repair overlaps with other pathways, so disease also reflects tissue exposure to endogenous aldehydes and replication demand, as in marrow failure.

IMF-091-01-0023-en	What trade-off do translesion polymerases make?	Their specialised active sites copy across damaged templates and prevent prolonged fork collapse, but with lower fidelity, so switching back to the replicative polymerase is essential and excessive bypass increases mutation.

IMF-091-01-0024-en	How do ATM and ATR differ in the damage they sense, and what does p53 do with the signal?	ATM responds strongly to double-strand breaks and ATR to replication-associated single-stranded DNA; p53 integrates damage with arrest, senescence, repair or apoptosis.

IMF-091-02-0001-en	What does phosphorylation of the RNA polymerase two carboxyl-terminal domain accomplish?	It promotes escape of the positioned polymerase from the promoter into elongation and recruits RNA-processing factors to the nascent transcript.

IMF-091-02-0002-en	How can a noncoding variant cause disease without changing protein sequence?	Enhancers act on promoters over long distances through factor binding, looping and coactivators, and genes use tissue- or stage-specific regulatory elements, so a variant can alter quantity, timing or cellular location of expression.

IMF-091-02-0004-en	Why does early addition of the seven-methylguanosine cap matter for a messenger RNA?	The cap protects the RNA, recruits processing and export factors, later supports translation initiation, and its complexes help distinguish proper polymerase-two transcripts from damaged RNA.

IMF-091-02-0005-en	Splicing joins exons without direct ATP use for bond chemistry. Why, and where is energy still needed?	Two transesterification reactions exchange existing bonds, forming a lariat intron and joining exons; energy is used for spliceosome assembly and remodelling.

IMF-091-02-0006-en	How can a synonymous or deep intronic variant be pathogenic, and why is proving it difficult?	It can disrupt a splicing enhancer, create a cryptic site or introduce a pseudoexon; proof needs RNA from relevant tissue, and accessible blood may express the transcript poorly or not at all.

IMF-091-02-0009-en	How can nonsense-mediated decay determine whether a premature stop codon causes simple loss or a dominant-negative effect?	Decay degrades many transcripts with premature stops, so the variant causes loss rather than abnormal protein; transcripts that escape decay can make dominant-negative or toxic truncated products.

IMF-091-02-0011-en	How does adenosine-to-inosine editing change a transcript's meaning, and how does it differ from mutation?	ADAR converts adenosine to inosine, which is read as guanosine, altering coding, splicing, structure and immune recognition; the change is in RNA, not the genome, and can be tissue specific.

IMF-091-02-0012-en	How do microRNAs and small interfering RNAs differ in how they silence targets?	MicroRNAs pair mainly through the seed region, usually lowering translation or promoting decay of many targets modestly; small interfering RNAs often pair extensively and guide Argonaute to cleave the target.

IMF-091-03-0005-en	Why do cells suppress general translation during nutrient deficiency, viral infection or endoplasmic-reticulum stress, and how?	Translation is energetically costly, using ATP for activation and GTP for elongation, so cells phosphorylate initiation factors to suppress general initiation while selected stress transcripts continue.

IMF-091-03-0007-en	Why do luminal domains of secretory-pathway membrane proteins end up facing the cell exterior?	Signal anchors and stop-transfer sequences fix topology in the endoplasmic reticulum, and vesicle transport preserves orientation, so luminal domains become extracellular after vesicle fusion.

IMF-092-01-0017-en	By what two routes can uniparental disomy cause disease?	Because both homologues come from one parent, it can cause imprinting disease, since expression is parent-of-origin specific, or unmask a recessive variant.

IMF-092-01-0018-en	What explains anticipation in unstable repeat-expansion disorders?	Repeat size may expand during gametogenesis, sometimes with parent-of-origin effects, so onset becomes earlier or severity greater across generations.

IMF-092-01-0019-en	What distinguishes penetrance from expressivity?	Penetrance is the proportion of people with a genotype who show a defined phenotype by a specified age; expressivity is the degree or pattern of phenotype among those affected.

IMF-092-01-0020-en	Why may a penetrance estimate from a referral clinic not apply to population screening?	Penetrance is influenced by ascertainment and phenotype definition, so an estimate from a selected referral population cannot be transferred directly to the general population.

IMF-092-01-0022-en	How can unaffected parents have more than one child with an apparently de novo variant?	Gonadal mosaicism means only a subset of the parent's cells carries the variant, so it can be transmitted repeatedly while the parent remains unaffected; low-level mosaicism may be missed in blood.

IMF-092-01-0023-en	In Bayesian pedigree reasoning, why may a negative test or unaffected status at a young age lower risk less than expected?	A negative result reduces risk only according to assay sensitivity and whether the familial variant is known, and unaffected status at a young age is weak evidence for late-onset disease.

IMF-092-02-0001-en	Why can recessive or late-onset disease alleles reach appreciable frequency while severe early-onset dominant variants rarely do?	Negative selection removes alleles with severe dominant effects, but recessive, late-onset, low-penetrance or selected alleles can persist, so rare does not mean pathogenic nor common harmless.

IMF-092-03-0003-en	Which abnormalities does chromosomal microarray generally miss despite genome-wide coverage, and why?	Because it measures copy number, it generally misses balanced rearrangements, many low-level mosaics, repeat expansions and small sequence variants.

IMF-092-03-0005-en	Why does adequate mean sequencing depth not guarantee that a variant would be detected?	Coverage is uneven: repeats, pseudogenes, high-GC regions, homologous genes and low-complexity sequence are difficult, so mean depth does not prove every base is adequately covered.

IMF-092-03-0007-en	Why can RNA sequencing of blood fail to show the consequence of a DNA variant?	It depends on expression in the sampled tissue and on transcript stability; nonsense-mediated decay may erase the abnormal transcript, and blood may not show muscle- or brain-specific isoforms.

IMF-092-03-0009-en	Why does finding a variant in an unaffected relative weaken but not refute disease association?	If penetrance is incomplete, carriers can remain unaffected, so an unaffected carrier does not disprove the association.

IMF-092-03-0010-en	Why should a variant of uncertain significance not drive irreversible predictive or surgical decisions?	Its disease association is unresolved, and it can be reclassified as population data, family studies, functional evidence or disease knowledge grow, so patients need a plan for review.

IMF-092-03-0011-en	Why does variant allele fraction in tumour testing not simply indicate zygosity?	It also reflects tumour purity, copy number, clonality and heterogeneity, and clonal haematopoiesis can contaminate blood or cell-free DNA and mimic tumour or germline findings.

IMF-092-03-0012-en	Why is cell-free DNA testing in maternal plasma a screening rather than a diagnostic test?	Placental mosaicism, maternal variants, vanished twin, malignancy and low fetal fraction affect results, and positive predictive value depends strongly on prior probability.

IMF-092-03-0013-en	How do analytical validity, clinical validity and clinical utility differ?	Analytical validity asks whether the assay detects the variant accurately, clinical validity whether the variant predicts phenotype, and clinical utility whether the result improves decisions or outcomes.

IMF-093-01-0004-en	Why does the location of a nucleic acid matter to pattern-recognition sensors?	Toll-like receptors sit on the plasma membrane or endosomes and other sensors in the cytosol, so nucleic acid in the wrong compartment, such as misplaced DNA, itself signals danger.

IMF-093-01-0006-en	Why is selectin binding alone insufficient for a leukocyte to leave the blood?	Selectins mediate only transient rolling; chemokines displayed on endothelial glycosaminoglycans must activate integrins, which then bind immunoglobulin-family molecules for firm adhesion before transmigration.

IMF-093-01-0007-en	Why do leukocyte-adhesion defects cause recurrent infection with little tissue pus despite high blood neutrophils?	Defective integrins, selectin ligands or trafficking prevent recruitment, so neutrophils accumulate in blood but fail to reach the infected tissue.

IMF-093-02-0005-en	How does linked recognition explain carrier-protein effects in conjugate vaccines?	The B-cell receptor captures the whole molecular complex, internalises it and presents derived peptides on class two, so helper T cells recognising those peptides can assist that B cell.

IMF-093-02-0006-en	How does T-cell receptor signalling become sensitive despite modest receptor affinity?	Repeated engagement, adhesion and microcluster formation amplify signalling, and the immunological synapse organises receptors so low-affinity recognition becomes directed action.

IMF-093-02-0007-en	What happens when a naive T cell recognises peptide-MHC without costimulation, and why does this matter?	Without CD28 binding B7 on an activated antigen-presenting cell, recognition can produce anergy, deletion or tolerance, so recognition alone does not automatically cause attack.

IMF-093-02-0008-en	Why does inhibiting calcineurin suppress T-cell activation?	Receptor signalling through calcium-calcineurin-NFAT and parallel pathways induces interleukin 2, its high-affinity receptor, survival proteins and cell-cycle entry, so blocking it limits activation.

IMF-093-02-0009-en	How does activation change where a naive T cell goes?	Unactivated cells leave the lymph node along sphingosine-1-phosphate gradients, whereas activation retains them for proliferation and then changes homing receptors so effectors reach infected tissue.

IMF-093-02-0012-en	Why do T-independent responses to repetitive polysaccharides give poor lasting protection?	They activate B cells without conventional T-cell help, giving rapid, mainly IgM responses with limited affinity maturation and memory, especially weak in young children.

IMF-093-02-0013-en	Why do superantigens cause massive cytokine release?	They crosslink T-cell-receptor variable regions to class two outside the peptide groove, bypassing peptide specificity and activating many clones instead of the tiny fraction conventional antigen activates.

IMF-093-02-0014-en	Why does a strong HLA-disease association not establish cause?	An allele may be neither necessary nor sufficient, and linked nearby variants and population ancestry complicate attribution, although typing can still guide transplantation or avoid severe drug reactions.

IMF-093-03-0001-en	How can low-affinity IgM still bind antigen strongly?	Affinity is the strength of one binding interaction, while avidity is the combined strength of multivalent binding, and IgM gains high avidity through its multiple binding sites.

IMF-093-03-0003-en	How does the neonatal Fc receptor explain both newborn protection and the long half-life of IgG?	It carries IgG across the placenta, so maternal IgG protects the newborn but can also transmit pathogenic autoantibodies, and it rescues IgG from degradation, extending half-life.

IMF-093-03-0004-en	What makes secretory IgA suited to mucosal defence?	Dimeric IgA is carried through epithelium by the polymeric-immunoglobulin receptor, a receptor-derived secretory component protects it from proteolysis, and it neutralises microbes and toxins with relatively little inflammation.

IMF-093-03-0005-en	Why does allergen-specific IgE not by itself prove clinical allergy?	It indicates sensitisation, and without a compatible exposure history it does not show that a clinical reaction will occur.

IMF-093-03-0006-en	Why does neutralisation not require Fc activity, and what limits it?	It works by blocking attachment, entry, fusion, enzyme action or toxin-receptor binding, so it depends on epitope access and concentration, and viruses escape by changing epitopes.

IMF-093-03-0007-en	Why does soluble monomeric IgG not strongly activate phagocytes?	Fc gamma receptors are triggered by clustered IgG on a coated particle, and receptor clustering is required, so single soluble molecules generally do not signal strongly.

IMF-093-03-0008-en	Why is class switching largely irreversible, and what does defective switching cause?	DNA recombination joins the variable region to a downstream constant gene and deletes the intervening DNA; defects cause hyper-IgM syndromes with impaired class-switched defence.

IMF-093-03-0009-en	How does affinity maturation select better antibodies, and what risk does it carry?	Somatic hypermutation alters variable regions, clones compete for antigen on follicular dendritic cells and follicular T-cell help, and higher-affinity clones survive; it risks autoreactivity and translocation.

IMF-093-03-0010-en	Why may antihistamines and adrenaline be insufficient in hereditary angioedema?	C1-inhibitor deficiency causes swelling through bradykinin rather than histamine, without typical urticaria, so it needs pathway-specific therapy, though airway emergency still requires immediate assessment.

IMF-093-03-0011-en	Why does paroxysmal nocturnal haemoglobinuria cause blood-cell injury and thrombosis?	Blood cells lose glycosylphosphatidylinositol-anchored complement regulators, so complement attacks them without the usual host protection.

IMF-093-03-0012-en	Why do early classical-component deficiencies cause lupus-like disease while C3 deficiency causes pyogenic infection?	Early classical components are needed for immune-complex clearance, whereas C3 is central to opsonisation, so losing it causes severe recurrent pyogenic infection.

IMF-093-03-0013-en	How are immune complexes normally cleared, and what happens when they persist?	Complement tags them and erythrocyte complement receptors carry them to liver and spleen for phagocytic removal; persistent complexes deposit in glomeruli, vessels, joints or skin and activate complement and Fc receptors.

IMF-094-01-0017-en	What do germline checkpoint insufficiency and therapeutic checkpoint blockade have in common clinically?	Both remove restraint on activation: germline insufficiency can cause lymphoproliferation and autoimmunity, and blockade can cause organ-specific inflammatory toxicities.

IMF-094-01-0018-en	Why can autoreactive B cells survive yet remain harmless, and what bypasses this restraint?	They stay silent without cognate T-cell help; Toll-like-receptor activation or defective clearance of nuclear material can bypass this, especially for receptors binding DNA- or RNA-containing complexes.

IMF-094-01-0019-en	Why do early classical complement deficiencies predispose to lupus-like disease?	Apoptotic debris and immune complexes are cleared less well, so debris persists and B-cell handling of self material changes.

IMF-094-01-0020-en	Why is immune privilege in the eye, brain, testis and placenta described as relative rather than absolute?	Barriers, limited lymphatic drainage and local inhibitory signals only limit inflammation; injury can release sequestered antigens and infection can trigger lasting immune access.

IMF-094-01-0021-en	What distinguishes molecular mimicry, epitope spreading and bystander activation as routes to lost tolerance?	Mimicry is cross-reaction between microbial and self epitopes; spreading extends a response to neighbouring determinants during tissue damage; bystander activation supplies cytokines and costimulation without receptor cross-reactivity.

IMF-094-01-0022-en	An autoantibody is found years before any disease. Why does that not mean it causes the disease by itself?	Autoimmunity usually needs genetic susceptibility plus environmental and stochastic events, so an autoantibody can precede disease without being sufficient.	Integrated Medical Foundations; chapter 94, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: f8a9954105d008d33f50f5572645e32bfe8c3ff23aa3dfd2d5a7e1ea0c3ad37c; editorial review pending	imf lang::en chapter::094 module::094-01 review::pending
IMF-094-01-0023-en	Why is autoimmunity described as a predictable cost of a diverse repertoire rather than a simple failure to identify self?	Stringent deletion would leave gaps in pathogen recognition, so some self-reactive clones are kept because weak self recognition supports survival or their receptors also see microbes.

IMF-094-01-0024-en	How does pregnancy illustrate context-specific rather than global tolerance?	Maternal antimicrobial defence is preserved while decidual regulatory cells, trophoblast HLA expression, uterine NK cells and local metabolic signals limit destructive responses at the interface.

IMF-094-02-0001-en	What effector distinguishes each of the four classical hypersensitivity types?	Type I is immediate and IgE-mediated, type II uses antibodies against cells, matrix or receptors, type III uses soluble immune complexes, and type IV is T-cell mediated.

IMF-094-02-0002-en	How does sensitisation prepare mast cells so that later allergen exposure triggers degranulation?	Interleukins 4 and 13 drive class switching to IgE, which binds high-affinity Fc epsilon receptors; re-exposure crosslinks this bound IgE and triggers degranulation.

IMF-094-02-0003-en	Why is intramuscular adrenaline, not an antihistamine, first-line for anaphylaxis?	Adrenaline supports vascular tone, relaxes the airway and reduces mediator release, buying time, whereas antihistamines do not reliably reverse life-threatening physiology.

IMF-094-02-0004-en	Why do broad allergy panels risk harm, and what should diagnosis rest on instead?	Sensitisation on skin or blood testing does not prove clinical allergy, so panels create false-positive labels and needless avoidance; diagnosis integrates reproducible history, timing, dose, cofactors and supervised challenge.

IMF-094-02-0005-en	How can antibody-mediated disease occur without cell killing, and why may neonatal forms be transient?	Antibodies can stimulate or block receptors, as in Graves disease and myasthenia; maternal IgG crosses the placenta and later disappears, so neonatal disease can resolve.

IMF-094-02-0006-en	Why do small complexes formed at antigen excess cause type III injury, and how does their immunofluorescence differ from anti-basement-membrane disease?	They evade clearance, deposit and activate complement, recruiting neutrophils; deposits appear granular, unlike the linear basement-membrane antibody of selected type II disease.

IMF-094-02-0008-en	What distinguishes patch testing from skin-prick testing, and why can irritant dermatitis mislead?	Patch testing assesses delayed contact responses and prick testing immediate sensitisation; irritant dermatitis directly damages the barrier and mimics allergy without antigen-specific memory.

IMF-094-02-0009-en	Why are anti-citrullinated-protein antibodies more useful than rheumatoid factor in rheumatoid arthritis?	Rheumatoid factor binds immunoglobulin Fc but is not specific, whereas anti-citrullinated-protein antibodies are more specific and may precede symptoms.

IMF-094-02-0010-en	Vessel calibre predicts which organs a vasculitis affects. Why is it not enough to name the cause?	Similar vessel injury can arise through T cells and macrophages, antineutrophil antibodies or immune complexes, so biopsy, serology, imaging, drug, infection and malignancy context are needed.

IMF-094-02-0011-en	In immune-mediated neurological disease, what distinguishes antibodies to surface receptors from responses to intracellular antigens?	Surface-receptor or ion-channel antibodies may respond quickly to antibody removal, whereas intracellular-antigen responses often mark tumour-associated cytotoxic T-cell injury.

IMF-094-02-0012-en	What distinguishes direct from indirect allorecognition, and why are alloimmune responses so strong?	Direct recognition sees intact donor HLA on donor antigen-presenting cells; indirect recognition sees donor peptides presented by recipient cells; high precursor frequency makes responses strong.

IMF-094-02-0013-en	Why does hyperacute rejection occur within minutes to hours, and how is it mostly prevented?	Preformed antibodies bind graft endothelium, activate complement and thrombose vessels, causing ischaemic necrosis; crossmatching and antibody screening prevent most cases.

IMF-094-02-0014-en	After allogeneic haematopoietic transplantation, why is suppressing donor T cells a trade-off?	Donor T cells cause graft-versus-host disease in skin, gut, liver and marrow, but donor immunity also provides a beneficial graft-versus-leukaemia effect, and suppression adds infection, malignancy and toxicity risk.

IMF-094-03-0001-en	Why do live attenuated vaccines give strong immunity, yet may be unsafe in severe immunodeficiency or pregnancy?	Limited replication induces strong humoral, cellular and mucosal responses with durable memory, but uncontrolled replication or fetal risk is possible depending on platform.

IMF-094-03-0002-en	How does conjugating a polysaccharide to a carrier protein overcome weak responses in young children?	B cells take up the conjugate and present carrier peptide to helper T cells, enabling class switching, affinity maturation, memory and herd effects through reduced carriage.

IMF-094-03-0003-en	Why do viral-vector vaccines support class I and class II presentation, and what can limit boosting?	Host cells make the antigen themselves, allowing both presentation routes; pre-existing or induced immunity to the vector can reduce booster effect.

IMF-094-03-0005-en	What distinguishes a correlate of protection from a mechanistic correlate, and why does waning serum antibody not equal lost protection?	A correlate is statistically associated with protection while a mechanistic correlate directly mediates it; protection can also rely on Fc function, T cells, mucosal immunity and memory recall.

IMF-094-03-0006-en	Why can a positive binding ELISA not be taken as evidence of neutralising antibody?	ELISA detects binding through an immobilised antigen or antibody and enzyme signal; binding alone does not prove that the antibody blocks function.

IMF-094-03-0007-en	How does the prozone effect produce a false-negative agglutination result, and how is it corrected?	Antibody excess prevents formation of an optimal antigen-antibody lattice, so visible agglutination fails; diluting the sample improves the result.

IMF-094-03-0008-en	Why can flow cytometry mislead about cell numbers and function?	Absolute counts need counting beads or haematology integration, marker presence does not always equal function, and processing can selectively lose fragile populations.

IMF-094-03-0009-en	How do classical and alternative pathway activity screens localise a complement defect?	Low classical with normal alternative suggests early classical deficiency; both low suggests C3 or terminal deficiency or consumption; low alternative with normal classical suggests an alternative-specific defect.

IMF-094-03-0012-en	Why can checkpoint inhibitors cause immune-related adverse events in nearly any organ?	Blocking CTLA4, PD1 or PD-L1 enhances T-cell activity through loss of peripheral restraint, which is not confined to the tumour, and events can appear even after therapy stops.

IMF-095-01-0005-en	Why is colonisation described as a succession rather than a single event at birth?	Delivery mode, feeding, antibiotics, contacts, geography, diet and host genetics keep shaping unstable early communities, which develop toward site-specific states over years.

IMF-095-01-0006-en	Why do claims of a substantial healthy placental microbiome remain controversial?	Low-biomass samples are highly vulnerable to reagent and environmental contamination, and detecting microbial DNA does not prove that living organisms colonised the site.

IMF-095-01-0007-en	In community assembly, what distinguishes ecological selection from drift?	Selection favours traits that fit the niche, whereas drift changes low-abundance populations randomly without reference to their traits.

IMF-095-01-0008-en	What is a priority effect, and why does it matter for community outcome?	Early colonisers alter the conditions later organisms meet, so the order of arrival, not only which organisms arrive, shapes the community that establishes.

IMF-095-01-0009-en	Two people host taxonomically different gut communities. Why need this not imply different function?	Different taxa can perform overlapping functions, so community membership and community output are not the same measurement.

IMF-095-01-0010-en	Why is higher diversity not universally a marker of health?	Vaginal health often involves low-diversity Lactobacillus-dominant states, while diverse oral plaque can include disease-associated communities; metric and sequencing depth also alter conclusions.

IMF-095-01-0011-en	How can inflammation arise in the gut without any new pathogen appearing?	Mucus, secretory IgA, antimicrobial peptides and epithelial oxygen consumption normally separate the luminal community from epithelium, and loss of that spatial separation alone can drive inflammation.

IMF-095-01-0012-en	Why can a course of antibiotics allow Clostridioides difficile to expand?	Antibiotics remove resident competitors, weakening colonisation resistance built on nutrient competition, attachment-site occupancy, bacteriocins, acidic metabolites and bile-acid transformation.

IMF-095-01-0013-en	Why is pathogenicity described as an interaction rather than a fixed property of a species?	Staphylococcus aureus can colonise the nose without symptoms yet cause abscess or bloodstream infection, so outcome depends on host state and location, not on the organism alone.

IMF-095-01-0014-en	What distinguishes a pathobiont from an opportunistic infection?	A pathobiont is a resident organism that contributes to disease when host or community conditions change, while opportunistic infection describes disease caused by low-virulence organisms because host defence is defective.

IMF-095-01-0015-en	Why does a positive culture from a nonsterile site not establish causation?	Such a result may reflect carriage of a resident organism rather than the cause of the current illness, so interpretation needs the clinical picture.

IMF-095-01-0016-en	How does frequent fermentable carbohydrate intake drive enamel demineralisation?	It selects acid-producing and acid-tolerant communities within plaque, and their local acid production demineralises enamel.

IMF-095-01-0017-en	Why is periodontal disease not explained by one necessary organism?	It arises from a dysbiotic subgingival biofilm interacting with inflammatory tissue destruction, so the process is a community and host interaction.

IMF-095-01-0018-en	How do the components of atopic dermatitis reinforce one another?	Barrier defects, type-two immune inflammation and episodic Staphylococcus expansion each worsen the others, so the disorder is self-reinforcing rather than driven by one factor.

IMF-095-01-0019-en	How does bacterial vaginosis differ from a conventional single-agent infection?	It involves a polymicrobial biofilm and altered metabolites rather than one causative organism, and community states vary by individual and ancestry.

IMF-095-01-0020-en	Why can the same gut organism be beneficial in one person and harmful in another?	Microbial function depends on substrate and strain, so an organism beneficial on fibre can produce harmful metabolites under a different diet.

IMF-095-01-0021-en	Why must germ-free animal findings on immune development be extrapolated to humans cautiously?	Germ-free animals show altered lymphoid tissue, IgA, T-cell subsets, barrier maturation and metabolism, but these are model-specific results rather than demonstrated human mechanisms.

IMF-095-01-0022-en	How does antibiotic tolerance in a biofilm differ from inherited resistance?	Tolerance comes from physiological state such as slow growth and altered gene expression within the matrix, while resistance is heritable; biofilms nonetheless favour both persistence and evolution.

IMF-095-01-0023-en	How can drug and microbiome effects run in both directions at once?	Drugs such as proton-pump inhibitors and metformin reshape the microbiota, while microbes activate or inactivate drugs, as in digoxin reduction, so observational links can be confounded.

IMF-095-01-0024-en	What distinguishes resilience from resistance in a microbial community, and why does one post-treatment sample not prove recovery?	Resilience is return toward function after disturbance and resistance is limited change during it; baseline variability is wide, so an individual's longitudinal range is more informative than a single later sample.	Integrated Medical Foundations; chapter 95, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: dec0ea0b0963b65f4b765498b18ecb67167115bb5110ecce5207c7f882ee4c1b; editorial review pending	imf lang::en chapter::095 module::095-01 review::pending
IMF-095-02-0001-en	Why is it wrong to say that antibiotic exposure makes a bacterium generate the resistance mutation it needs?	Mutations arise randomly during replication or repair and are then enriched by selection; the drug selects among existing variants rather than directing which mutation appears.

IMF-095-02-0002-en	How can resistance be selected even when plasma concentrations look adequate?	Exposure differs across tissue, abscess, biofilm, gut, urine and intracellular compartments, and a subtherapeutic concentration at one of those sites can select resistant organisms.

IMF-095-02-0003-en	Why does reducing antimicrobial use not guarantee that population resistance falls quickly?	Compensatory mutations lower the fitness cost without restoring susceptibility, and resistance can persist because its cost is low or because it is linked to other selected genes.

IMF-095-02-0004-en	What distinguishes transformation, transduction and conjugation?	Transformation takes up naked environmental DNA, transduction moves bacterial genes inside bacteriophages, and conjugation transfers plasmids or other elements through direct cell contact.

IMF-095-02-0005-en	Why can use of one antibiotic select resistance to several unrelated drugs?	One plasmid may carry several resistance genes, so selecting for the plasmid with a single drug co-selects every resistance determinant it carries.

IMF-095-02-0006-en	Integrons are not self-mobile elements, so how do they spread resistance arrays?	They capture gene cassettes at a recombination site and express them from a promoter, and they travel between cells by riding on plasmids or transposons.

IMF-095-02-0007-en	How can a bacteriophage make its bacterial host more damaging to people?	A temperate phage can integrate as a prophage and confer toxins or other traits, as in selected diphtheria, cholera and Shiga-toxin systems, and induction can release particles and toxins.

IMF-095-02-0008-en	Why does the presence of a CRISPR-Cas system not guarantee that a strain will resist acquiring resistance plasmids?	CRISPR-Cas gives RNA-guided defence against matching nucleic acids, but mobile elements evolve anti-CRISPR mechanisms and transfer still succeeds when ecological conditions favour it.

IMF-095-02-0009-en	Why can the name of a beta-lactamase not predict activity against every beta-lactam?	Permeability, porin loss, efflux and additional mechanisms act alongside the enzyme, so the observed phenotype emerges from the whole combination.

IMF-095-02-0010-en	Give an example showing that a similar resistance phenotype can arise through distinct biology.	Enterococcal vancomycin resistance replaces the terminal cell-wall target chemistry, while intermediate resistance in staphylococci instead involves a thickened cell wall and heterogeneous subpopulations.

IMF-095-02-0011-en	What distinguishes tolerance, persistence and heteroresistance from inherited resistance?	Tolerance is survival without a raised inhibitory concentration, persistence is a small phenotypic subpopulation surviving transient exposure, and heteroresistance is a resistant minority within an apparently susceptible isolate.

IMF-095-02-0012-en	Why can a susceptible laboratory result still be followed by treatment failure?	Breakpoints assume standard conditions, so poor source control, limited penetration, impaired immunity, poor adherence or wrong organism identification can defeat an active drug.

IMF-095-02-0013-en	Why does detecting a virulence gene not prove that the organism caused the current syndrome?	Virulence factors also support colonisation and environmental survival, so their presence describes capacity in some context rather than causation of this illness.

IMF-095-02-0014-en	Why is withholding necessary early therapy in severe infection not stewardship?	Stewardship aims to keep treatment effective while reducing unnecessary selection, using narrow agents, optimised dosing, source control, timed review and shorter duration when evidence supports it.

IMF-095-03-0001-en	Why should an altered community found in disease not be called a cause on that basis alone?	Dysbiosis has no universal taxonomic definition, and illness, diet, drugs, transit and inflammation all change microbiota, so the change may be consequence rather than cause.

IMF-095-03-0002-en	What does a stool sample fail to represent, despite being the usual specimen?	Stool is shed luminal material and does not directly represent mucosa, small intestine, proximal colon or biofilm, and it varies with collection, storage, oxygen, extraction and transit.

IMF-095-03-0004-en	What can shotgun metagenomics resolve that sixteen-S sequencing cannot, and what can neither show?	Shotgun sequencing resolves more genes and strains than marker-region amplification, but neither proves gene expression and shotgun also detects dead organisms.

IMF-095-03-0006-en	Why does a low stool butyrate concentration not establish low butyrate production?	Stool concentration reflects production minus host and microbial uptake, so heavy colonocyte consumption can leave little butyrate in stool despite active fermentation.

IMF-095-03-0007-en	How do antibiotics change bile-acid biology in a way that favours Clostridioides difficile?	They reduce microbial deconjugation and conversion to secondary bile acids, and the altered bile-acid environment changes germination and growth of Clostridioides difficile.

IMF-095-03-0008-en	Why is the association between trimethylamine N-oxide and cardiovascular outcomes hard to read causally?	Diet supplies the choline and carnitine precursors and kidney clearance determines the concentration, so both confound the association and therapeutic causality is still under study.

IMF-095-03-0009-en	Why are facultative organisms that expand during inflammation best seen as markers and amplifiers?	Inflammation raises oxygen and alternative electron acceptors and releases nutrients, so these organisms exploit conditions the host created, then worsen barrier and inflammation through feedback.

IMF-095-03-0010-en	Why does testing formed stool for Clostridioides difficile promote overdiagnosis?	Detection of a toxigenic organism without compatible diarrhoea may represent colonisation rather than infection, so testing patients without the syndrome mislabels carriers.

IMF-095-03-0011-en	Why does the success of faecal microbiota transplantation in recurrent Clostridioides difficile infection not justify its use across dysbiosis-associated disease?	That indication has a clear ecological mechanism of restoring community function, while donor screening cannot eliminate unknown risks and other conditions lack comparable evidence.

IMF-095-03-0013-en	Why does a randomised dietary or antibiotic intervention still leave attribution to the microbiota uncertain?	These interventions have direct host effects as well as microbial ones, so an improved outcome need not have travelled through the proposed microbial mediator.

IMF-095-03-0014-en	Why are Koch's postulates difficult to apply to polymicrobial ecological disease?	No single organism may be necessary or sufficient, so causal reasoning shifts to temporality, dose, manipulation, mechanism and reversibility, and a community function can be causal across differing taxonomic configurations.

IMF-096-01-0001-en	Why is a pathological pattern not automatically a diagnosis, and how should interpretation proceed?	The same pattern can arise from several causes, and one cause can produce different patterns by dose, duration, tissue, reserve and treatment, so reasoning runs from mechanism to morphology and back to a ranked set of mechanisms.

IMF-096-01-0002-en	What determines whether a tissue adapts to increased demand by hypertrophy or by hyperplasia?	Hypertrophy enlarges cells by synthesising proteins and organelles and dominates where mature cells divide poorly, such as cardiac and skeletal muscle; hyperplasia increases cell number and requires tissue able to divide.

IMF-096-01-0004-en	Through which cellular mechanisms does atrophy develop, and why does prolonged atrophy matter?	Lower protein synthesis, increased proteolysis and autophagy shrink cells; this conserves energy, but prolonged loss of specialised structures reduces reserve.

IMF-096-01-0005-en	What does squamous metaplasia in a smoker's airway gain and lose?	Squamous epithelium tolerates smoke better than ciliated columnar epithelium, but mucociliary clearance and local defence decline, and persistent stress creates a setting for dysplasia and malignancy.

IMF-096-01-0006-en	What distinguishes dysplasia from invasive cancer, and why can mild dysplasia regress?	Dysplasia is disordered growth with atypia, abnormal maturation and disturbed architecture but no invasion; mild dysplasia can regress once the initiating stimulus is removed, whereas severe dysplasia approaches carcinoma in situ.

IMF-096-01-0008-en	How does reduced oxidative phosphorylation lead to cell swelling in reversible injury?	Falling adenosine triphosphate weakens ion pumps, so sodium and water enter and potassium is lost, swelling cells and organelles (hydropic degeneration) and dilating the endoplasmic reticulum.

IMF-096-01-0009-en	Why does cytosolic calcium entry drive injury toward irreversibility?	Calcium activates phospholipases, proteases, endonucleases and energy-consuming enzymes, which attack membranes, proteins and nucleic acids while further draining energy.

IMF-096-01-0011-en	Why might a blood biomarker of tissue injury be absent even though cells have died?	Biomarkers enter blood only when injury, release, distribution and clearance permit, so timing and kinetics can hide real cell death.

IMF-096-01-0012-en	What distinguishes coagulative from liquefactive necrosis in mechanism and typical setting?	In coagulative necrosis proteins and enzymes denature, so ghostlike architecture persists temporarily, as in ischaemic solid organs; in liquefactive necrosis tissue is digested to viscous material, as in cerebral infarction and abscesses.

IMF-096-01-0013-en	Why does apoptosis usually provoke less inflammation than necrosis, and when can it still harm tissue?	Caspases dismantle the cell into membrane-bound fragments that are rapidly cleared, keeping contents contained; extensive apoptosis or failed clearance can still affect tissue function.

IMF-096-01-0014-en	Why might even a regenerative organ heal by scar rather than regeneration?	Scar forms when injury is extensive, infection persists, perfusion remains poor or the supporting matrix is destroyed; fibrosis restores mechanical continuity but rarely specialised architecture.

IMF-096-01-0015-en	What distinguishes hyperaemia from congestion in mechanism and consequence?	Hyperaemia is active inflow from arteriolar dilation, as in exercise or inflammation; congestion is passive impaired outflow that distends veins and capillaries and can cause hypoxia, oedema and haemorrhage.

IMF-096-01-0017-en	How do heart failure and severe protein loss each cause oedema through different forces?	Heart failure raises venous hydrostatic pressure, pushing fluid out; severe protein loss lowers the plasma oncotic pressure, largely generated by albumin, that draws fluid back into vessels.

IMF-096-01-0018-en	Why do exudates contain more protein than transudates, and why is the distinction imperfect?	Exudates arise from increased permeability or local inflammation, whereas transudates reflect altered hydrostatic or oncotic forces; diuretics, prolonged disease, bleeding, malignancy and mixed mechanisms alter composition.

IMF-096-01-0019-en	Why can a small intracranial bleed be catastrophic while repeated small occult losses cause a different problem?	The skull limits expansion, so a small intracranial volume matters greatly; repeated occult loss causes little haemodynamic change per episode but depletes iron.

IMF-096-01-0020-en	How does Virchow's triad explain why arterial and venous thrombi differ in composition?	Arterial thrombi form on disrupted plaque under high shear, driven by endothelial injury, and are platelet rich; venous thrombi form where stasis and coagulation dominate and contain abundant fibrin and red cells.

IMF-096-01-0021-en	How can a venous thrombus reach a systemic artery, and what determines an embolus's consequence?	A communication between venous and arterial circulations permits paradoxical embolism; outcome depends on embolus size, collateral supply, tissue sensitivity to hypoxia, and whether the obstruction is sterile or infected.

IMF-096-01-0023-en	In shock, why does a normal or restored blood pressure not prove adequate perfusion?	Early compensation redistributes flow to maintain pressure, and after hypoperfusion endothelial dysfunction, capillary leak and microthrombosis can persist, so pressure recovery does not ensure microvascular flow.

IMF-096-02-0002-en	How does increased microvascular permeability produce both swelling and slower blood flow in acute inflammation?	Protein-rich fluid leaves the vessels into tissue, causing swelling, and the loss of fluid concentrates red cells within vessels, which slows flow.

IMF-096-02-0005-en	Why is resolution of inflammation described as active, and what happens if it fails?	The stimulus must be removed, mediators decay, neutrophil recruitment stop and dead cells be cleared, with macrophages ingesting apoptotic neutrophils; failure at any step can sustain injury after the trigger has gone.

IMF-096-02-0008-en	What distinguishes granulation tissue from granulomatous inflammation?	Granulation tissue is early, highly vascular repair tissue of capillaries, fibroblasts, inflammatory cells and loose matrix; granulomatous inflammation is an organised macrophage response to hard-to-eradicate material.

IMF-096-02-0009-en	How does the balance between matrix metalloproteinases and their inhibitors determine the quality of repair?	Excess degradation weakens repair, whereas excessive synthesis or inadequate degradation produces fibrosis.

IMF-096-02-0010-en	Why can the early appearance of a healed wound overstate its mechanical maturity?	Tensile strength rises only gradually through collagen accumulation and cross-linking and rarely returns to that of uninjured tissue.

IMF-096-02-0011-en	Why is organ fibrosis self-reinforcing and only partly reversible?	Transforming growth factor beta increases matrix synthesis and suppresses degradation, and tissue stiffness alters cell behaviour through mechanotransduction; cross-linked matrix, vascular remodelling and parenchymal loss limit regression.

IMF-096-02-0014-en	What defines sepsis, and why must reasoning address both trigger and host response?	Sepsis is a dysregulated host response to infection with organ dysfunction; microbial burden can fall while inflammatory and microvascular injury continues.

IMF-096-03-0001-en	Why does diagnostic pathology begin before tissue reaches the laboratory?	The clinical question determines what is sampled, how fast it is handled, and whether it must be sterile, unfixed, frozen or protected from light; an excellent test on the wrong specimen cannot answer the right question.

IMF-096-03-0002-en	How can a small biopsy mislead, and why must allocation of limited tissue be planned?	It may miss a focal lesion or capture only necrosis, ulceration or reactive tissue; scarce tissue must be divided in advance among histology, microbiology, flow cytometry, cytogenetics and molecular tests.

IMF-096-03-0003-en	Why is block sampling at gross examination a deliberate trade-off?	More blocks increase detection but consume time and tissue, while too few create false reassurance, so blocks target tumour, interface, normal tissue, deepest invasion and closest margins.

IMF-096-03-0004-en	How can fixation and decalcification compromise later testing?	Formalin cross-links proteins, but delayed, too short or excessive fixation alters staining and molecular assays, and decalcification may damage antigens and nucleic acids.

IMF-096-03-0005-en	Why is cellular atypia on a haematoxylin and eosin section not proof of malignancy?	Repair, infection, radiation and degeneration can all produce alarming cells, so atypia is not synonymous with malignancy.

IMF-096-03-0006-en	Why is a special stain evidence within a context rather than an automatic diagnosis?	Its sensitivity depends on organism burden and preservation, and apparent organisms may be contaminants or precipitate.

IMF-096-03-0007-en	Why is a staged immunohistochemistry panel preferred over a broad panel without a hypothesis?	No marker is perfectly specific, so a broad panel can yield contradictory incidental results; a staged panel tests plausible diagnoses in sequence while conserving tissue.

IMF-096-03-0008-en	Why is the least invasive specimen not always the best choice?	Cytology is minimally invasive but gives less architecture than core biopsy or excision, and if uncertainty forces repeated procedures it may not be the least costly.

IMF-096-03-0010-en	What distinguishes a prognostic marker from a predictive marker?	A prognostic marker estimates outcome independent of a particular treatment, whereas a predictive marker estimates response or resistance to a specific therapy.

IMF-096-03-0011-en	How do tumour grade and stage differ, and why does a positive margin not have a fixed meaning?	Grade describes biological appearance or differentiation and stage anatomical extent; a positive margin's significance depends on organ, procedure, tumour type and whether re-excision is possible.

IMF-096-03-0012-en	When morphology is discordant with the clinical picture, what should be reviewed?	Specimen identity, sampling, technical quality, test performance and alternative mechanisms, because patterns such as granulomas or necrosis have differential diagnoses rather than being final explanations.

IMF-096-03-0014-en	Why should an autopsy cause of death be a causal sequence rather than a list of abnormalities?	Post-mortem change and terminal events complicate interpretation, so the cause of death must form a defensible sequence explaining how disease led to death.

IMF-097-01-0001-en	Why need plasma concentration, receptor occupancy, and measured effect not change in parallel?	Each link from free concentration at the site of action, through target engagement and signal transduction, to cellular, organ, and whole-person responses can amplify, buffer, delay, or oppose the one before it.	Integrated Medical Foundations; chapter 97, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 09948eb4a680931feaeeb13e80cd863ce2e4ea691c7dd897669c6a8f233f25a4; editorial review pending	imf lang::en chapter::097 module::097-01 review::pending
IMF-097-01-0002-en	Why does doubling ligand concentration usually fail to double receptor occupancy?	Fractional occupancy equals concentration divided by concentration plus KD, a rectangular hyperbola that approaches full occupancy asymptotically, so it is near-proportional only at very low concentrations.	Integrated Medical Foundations; chapter 97, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 09948eb4a680931feaeeb13e80cd863ce2e4ea691c7dd897669c6a8f233f25a4; editorial review pending	imf lang::en chapter::097 module::097-01 review::pending
IMF-097-01-0003-en	How can two ligands with the same KD differ in how long they engage their target?	Equilibrium affinity hides association and dissociation rates; residence time is roughly the reciprocal of the dissociation rate, so a slowly dissociating ligand can sustain engagement after free concentration falls.

IMF-097-01-0004-en	What distinguishes affinity from efficacy, and why can a partial agonist not reach the maximal response even at high occupancy?	Affinity describes binding, whereas efficacy is the capacity of a bound ligand to generate a response; a partial agonist contributes less activation per occupied receptor, so it cannot reach the system's maximum.

IMF-097-01-0005-en	Why can a partial agonist reduce the response when a full agonist is present?	It occupies receptors while contributing less activation than the full agonist would, so the same molecule can appear agonistic or antagonistic depending on context.

IMF-097-01-0006-en	What distinguishes an inverse agonist from a neutral antagonist, and when does the difference become observable?	An inverse agonist stabilises inactive conformations and reduces constitutive activity, while a neutral antagonist blocks agonist binding without changing basal activity; they differ visibly only when constitutive signalling is appreciable.

IMF-097-01-0007-en	Why must biased agonism be measured against an explicit reference ligand and assay?	Bias means a ligand favours one active conformation and activates downstream pathways in different proportions, but signal amplification can mimic such selectivity.

IMF-097-01-0008-en	Why is EC50 a measure of potency rather than necessarily an affinity constant?	It is the concentration producing half the observed maximum in the measured system, and it depends on affinity, efficacy, receptor abundance, coupling, tissue access, competing ligands, and the chosen endpoint.

IMF-097-01-0009-en	Why does higher potency not make a drug better?	Higher potency only means less concentration is needed for a specified effect; it does not make the drug inherently more efficacious, safer, or clinically superior.

IMF-097-01-0010-en	How do spare receptors allow EC50 to be lower than KD?	Signal amplification lets a small fraction of receptors recruit enough downstream machinery for full effect, so maximal response occurs before all receptors are occupied.

IMF-097-01-0011-en	How does progressive irreversible receptor inactivation change the curve in a tissue with receptor reserve?	While reserve is consumed the curve shifts rightward with unchanged Emax; once it is exhausted the maximum falls. Reserve varies among tissues, so one agonist can be full in one organ and partial in another.

IMF-097-01-0012-en	How does a competitive antagonist change the agonist concentration-response curve, and why?	It binds reversibly at the agonist recognition site without activating it, so more agonist can surmount it, giving a parallel rightward shift with unchanged maximum in an ideal system.

IMF-097-01-0013-en	Why does noncompetitive antagonism usually lower the maximum response, and why may this be hidden at first?	Irreversible orthosteric binding, allosteric binding, downstream transducer block, or channel block cannot be overcome by more agonist, but spare receptors can initially conceal the fall in maximum.

IMF-097-01-0022-en	Why do repeated wells from one preparation not show that a concentration-response result generalises?	Repeated wells mostly estimate technical variation; estimating generalisability requires replication across independent biological preparations.

IMF-097-01-0023-en	Why should a steep Hill coefficient not be read as the number of binding sites?	A steep slope can arise from cooperativity, amplification, heterogeneity, thresholds, or assay compression.

IMF-097-01-0024-en	Why can potent target engagement in a simplified assay fail to yield a useful therapy?	Relevant cells may be inaccessible, redundant pathways may compensate, the same target in another tissue may cause harm, and selectivity at low exposure can be lost at higher exposure.

IMF-097-02-0001-en	Why is an association between a target and disease not enough to validate the target?	Validation needs independent evidence that manipulating the target changes disease-relevant biology, an understood direction and timing of intervention, and human variation that predicts compatible effects.

IMF-097-02-0002-en	What are the trade-offs between phenotypic and target-based discovery?	Phenotypic screens preserve integrated biology but complicate mechanism and optimisation, whereas target-based screens are tractable but may oversimplify disease.

IMF-097-02-0003-en	Why is increasing a compound's lipophilicity a mixed benefit during optimisation?	It can improve membrane passage while increasing nonspecific binding, metabolic turnover, or tissue accumulation, showing that optimising one feature may worsen another.

IMF-097-02-0004-en	Why does lowering a biomarker not guarantee clinical benefit?	A biomarker can support mechanism without being a validated surrogate; if the marker is not causal or off-target harm offsets the gain, a better laboratory value does not guarantee better outcomes.

IMF-097-02-0005-en	Why is in-vitro activity seen only at unrealistically high concentration weak translational evidence?	Experimental concentration must be compared with achievable unbound human exposure, and activity far above that exposure says little about what will happen in people.

IMF-097-02-0006-en	Why is the no-observed-adverse-effect level not proof of safety, and what shapes the starting human dose?	It is an experimental boundary, not proof of zero risk; the starting dose integrates animal exposure, pharmacologically active dose estimates, uncertainty factors, target biology, and possible steep or delayed toxicity.

IMF-097-02-0007-en	Why is manufacturing part of pharmacology, and why do process changes need comparability evidence?	Identity, purity, stability, formulation, particle size, excipients, and release characteristics determine delivered exposure, and impurities may have distinct toxicity, so a changed process can change what patients receive.

IMF-097-02-0008-en	In first-in-human studies, why are patients sometimes chosen instead of healthy volunteers?	Healthy volunteers are used when risk is acceptable, but toxicity, an irreversible mechanism, or disease biology can make exposing healthy people inappropriate.

IMF-097-02-0009-en	Why is phase two dose selection an estimation problem rather than a search for the highest tolerated dose?	Too little exposure can discard an effective mechanism and too much can create adverse effects that obscure benefit, so several doses with exposure-response modelling beat a single arbitrary choice.

IMF-097-02-0010-en	Why does intention-to-treat analysis preserve the protection of randomisation, unlike per-protocol analysis?	It analyses participants in their assigned groups, whereas per-protocol analysis answers a different question and is vulnerable to selection after randomisation.

IMF-097-02-0012-en	Why are poor adherence and crossover a particular threat in a non-inferiority trial?	They make treatments look falsely similar, while non-inferiority already depends on confidence that the active control would have worked in that trial.

IMF-097-02-0013-en	What distinguishes a legitimate adaptive design from changes made after seeing results?	Adaptive designs modify enrolment, allocation, dose, or sample size by prospectively defined rules that preserve error control; unprespecified changes after seeing results are ordinary bias.

IMF-097-02-0014-en	What are the value and limits of spontaneous adverse-event reports?	They are valuable signals, but they lack reliable denominators and are influenced by publicity, so a signal should be investigated proportionately rather than dismissed or assumed causal.

IMF-097-03-0001-en	Beyond a statistical association, what makes a pharmacogenomic result clinically useful?	It must change a decision (whether to prescribe, which drug, starting dose, adjustment speed, or toxicity monitoring) using an accurately measured variant linked to a reproducible phenotype in the relevant context.

IMF-097-03-0002-en	Why can reduced metabolic function raise toxicity with one drug but reduce efficacy with another?	For an active parent drug, reduced metabolism raises exposure; for a prodrug requiring activation, it lowers active-metabolite exposure, so the direction cannot be inferred without knowing the pathway.

IMF-097-03-0004-en	How can variation in an antigen-presenting molecule create risk of a specific drug hypersensitivity?	The variant molecule can present a drug-related antigen to T cells, creating a strong risk of that particular reaction.

IMF-097-03-0005-en	In causality assessment, why may rechallenge be unacceptable and dechallenge misleading?	Rechallenge strengthens inference but is unethical after a severe reaction, and improvement after stopping can mislead when disease resolves naturally or several treatments stop together.

IMF-097-03-0006-en	Why can a severe cutaneous or systemic drug reaction progress after the drug is stopped?	Immune activation has become self-sustaining, so removing the drug no longer halts the reaction.

IMF-097-03-0007-en	How does local exposure explain drug toxicity in the liver and kidney?	The liver meets high concentrations during first-pass metabolism, and the kidney concentrates filtrate, exposing tubules to transport-dependent toxicity and crystals; organ toxicity reflects local exposure and vulnerability.

IMF-097-03-0008-en	Why does enzyme inhibition act quickly while induction develops and resolves slowly?	Inhibition usually begins as inhibitor concentration rises, whereas induction requires the amount of enzyme protein to change.

IMF-097-03-0009-en	How can several sedatives dangerously depress breathing without any pharmacokinetic interaction?	Their effects combine at a shared physiological outcome, so they jointly depress consciousness and ventilation without changing one another's concentrations.

IMF-097-03-0010-en	Why can serum creatinine look normal in an older adult with low filtration?	When muscle mass is low, serum creatinine can stay normal despite low filtration, masking the reduced renal reserve common in older adults.

IMF-097-03-0011-en	Why should untreated maternal illness not be treated as a zero-risk alternative in pregnancy?	Maternal disease carries its own risk, and because evidence is mostly observational, uncertainty can itself cause harm when effective treatment is withheld; drug risk must be compared against it.

IMF-097-03-0012-en	Why does blaming an individual for a medication error without examining workflow fail to improve safety?	It preserves the conditions, such as similar names, confusing units, or incomplete reconciliation, that produced the error; systems should make the intended action easy and dangerous action difficult.

IMF-097-03-0013-en	What does regulatory approval mean, and why can regulators reasonably reach different decisions?	Approval means evidence supports a favourable benefit-risk balance for a defined indication, population, dose, and product, not complete knowledge; available treatments, endpoints, mandates, and tolerance of uncertainty differ.

IMF-097-03-0014-en	Why must a newly detected drug risk be judged by absolute frequency, not relative risk alone?	A dramatic relative risk may mean a small absolute excess, whereas a modest relative increase in a common serious outcome may matter greatly.

IMF-099-01-0001-en	Why should clinical assessment avoid interpreting every learning failure as loss of memory?	Memory is not a single faculty: a person can acquire a skill without recalling the practice episode, so assessment separates sensory access, attention, encoding, retention, retrieval, language, motivation, and performance.

IMF-099-01-0002-en	What distinguishes habituation from sensory fatigue?	In habituation the response can recover after time or a novel stimulus, showing that the nervous system is estimating the stimulus's significance rather than simply failing to sense it.

IMF-099-01-0009-en	Why does intermittent reinforcement help explain durable checking and gambling, compared with continuous reinforcement?	Continuous reinforcement gives rapid acquisition but quick extinction when reward stops, whereas intermittent reinforcement with unpredictable response number or timing makes behaviour persistent.

IMF-099-01-0011-en	When is instruction by demonstration most likely to change a learner's behaviour?	When the demonstrated action is feasible in the learner's own environment and feedback corrects performance rather than merely restating information.

IMF-099-03-0011-en	In the capability-opportunity-motivation model, why can neither moral exhortation nor education fix every barrier?	Different gaps need different tools: training for capability, reminders for memory, environmental redesign for opportunity, and advice that is unaffordable or unsafe cannot be followed at all.

IMF-099-03-0012-en	Why can treating stage assignment as a diagnosis mislead, and how does motivational interviewing respond to ambivalence instead?	People do not always progress in order and stage boundaries are imprecise; motivational interviewing explores mixed motives collaboratively, elicits the person's own reasons, and avoids reflexive argument.

IMF-099-03-0014-en	Why is relapse common after behaviour change, and how should a lapse be handled?	Old cue-response pathways, rewards, stressors, and social contexts persist; a lapse is information about the plan, managed by rapid review, self-compassion, and a concrete restart to prevent abandonment.

IMF-100-01-0003-en	Why might missed appointments be wrongly attributed to irresponsibility, and what formulation corrects this?

IMF-100-01-0004-en	How does outcome knowledge distort the review of an adverse event?	Once the diagnosis or event is known, earlier ambiguous signs appear obvious, and this hindsight bias exaggerates how predictable the outcome was.

IMF-100-01-0005-en	Why can the just-world tendency lead observers to blame patients for illness or trauma?

IMF-100-01-0006-en	Why does general approval of exercise not guarantee that a person walks today in unsafe weather?	Attitudes predict behaviour best when they are specific, accessible, stable, and relevant to the situation, and a general attitude does not match that particular situation.

IMF-100-01-0007-en	Through cognitive dissonance, why can coercive public commitment entrench resistance rather than create agreement?	Dissonance from acting against one's self-concept can be reduced by adding justification or avoiding information, not only by changing belief, so forced commitment may harden resistance.

IMF-100-01-0008-en	What determines whether a persuasive message is processed carefully or heuristically?	High motivation and capacity favour careful evaluation of evidence, while limited attention favours cues such as expertise, familiarity, emotion, or social endorsement; both can be adaptive.

IMF-100-01-0010-en	Why can advertising the high prevalence of misconduct backfire, and how is this avoided?	A descriptive norm that misconduct is common can normalise it, so the message should be paired with a clear valued standard of what is approved.

IMF-100-01-0011-en	What strengthens conformity, and why can one visible dissenter weaken it even with a different answer?	Uncertainty, unanimity, public responding, and group importance strengthen conformity; any visible dissenter breaks unanimity and so reduces the pressure.

IMF-100-01-0013-en	Why is the use of compliance techniques ethically sensitive when seeking a patient's consent?	Techniques like small initial commitments, reciprocity, or scarcity are not inherently deceptive, but asymmetries of knowledge and power mean a yes gained by social pressure is not consent.

IMF-100-01-0014-en	Under what conditions does authority make harmful action easier, and what makes safety objections actionable?	Harm is easier when responsibility feels transferred upward, tasks are fragmented, and dissent seems disloyal; escalation pathways, graded assertiveness, closed-loop communication, and leaders who thank concern-raisers help.

IMF-100-01-0022-en	Why may a patient's apparent agreement not reflect their preference, and how should clinicians respond?	Low-power individuals monitor others closely and bear greater risk from conflict, so agreement may reflect dependence; clinicians should offer private opportunities for questions and make refusal genuinely safe.

IMF-100-02-0001-en	What distinguishes cultural humility from claiming cultural competence as mastery of a group?

IMF-100-02-0002-en	Why is eliciting a patient's explanatory model clinically useful, and what does it ask?

IMF-100-02-0003-en	Why are both dismissal and uncritical acceptance of traditional or herbal practices risky?

IMF-100-02-0013-en	Why can reassurance given before understanding feel dismissive, and what makes reassurance realistic?	Empathy means first communicating an accurate effort to understand the person's perspective and emotion; realistic reassurance then identifies what is known, what will be done, and how uncertainty will be managed.

IMF-100-02-0014-en	In a conflict after harm, why is apology more effective than an early technical explanation?	Conflict often reflects fear, unmet needs, or prior harm; apology acknowledges harm and responsibility, while defensive technical explanation before recognition tends to intensify conflict.

IMF-100-03-0001-en	Why is labelling someone nonadherent without specifying the behaviour and reason counterproductive?	Plans can fail because they are ineffective, unaffordable, confusing, or burdensome, so the label turns an outcome into a character judgment and blocks useful intervention.

IMF-100-03-0002-en	Why do refill data and electronic containers not directly measure medication ingestion?	Refill data estimate possession and electronic containers record opening, not swallowing; self-report is informative only when honest disclosure feels safe.

IMF-100-03-0005-en	Why is the placebo response observed in a trial broader than the true contextual placebo effect?	It also includes spontaneous change, regression to the mean, measurement effects, and reporting, not only effects of meaning, expectation, and context.

IMF-100-03-0006-en	How can clinicians disclose risks without amplifying nocebo effects?	Present frequency and severity neutrally, distinguish common transient effects from urgent danger, explain what action to take, and report both affected and unaffected proportions, without concealing material risks.

IMF-100-03-0007-en	Why does open-label placebo research not justify deceptive placebo use, and how can context be used ethically?	Results are condition-specific and deception undermines trust and valid consent; clear rationale, proportionate confidence, empathic attention, a coherent plan, and follow-up strengthen contextual healing ethically.

IMF-100-03-0008-en	Why is a number needed to treat not a fixed property of a drug?	It is the reciprocal of an absolute risk difference over a stated period, and the same relative effect gives different absolute benefit at different baseline risks.

IMF-100-03-0009-en	Why should numbers accompany verbal labels such as rare, and why keep denominators consistent?	Verbal labels are interpreted inconsistently, and switching denominators such as one in ten versus five in a thousand creates avoidable work in comparison.

IMF-100-03-0010-en	What framing imbalance should balanced risk communication avoid, and why?	Presenting benefits as relative effects and harms as absolute effects unbalances the comparison, and framing changes choices even when information is mathematically equivalent.

IMF-100-03-0011-en	Why is shared decision-making not the same as offering a menu, and what does each party contribute?	Clinical expertise defines medically reasonable options and evidence, while the patient holds authority over values, lived circumstances, and acceptable trade-offs; a menu without guidance omits the clinician's part.

IMF-100-03-0012-en	How can a strong recommendation remain compatible with autonomy, and when does offering choice fail?	It is compatible when reasons and uncertainty are clear and refusal is not punished; asking a patient to choose among options they cannot understand or access transfers burden rather than sharing power.

IMF-100-03-0013-en	Why should capacity not be judged from diagnosis or an unusual decision, and what comes before concluding incapacity?	Capacity is decision- and time-specific and fluctuates with delirium, pain, fear, or communication barriers; support, interpreters, sensory aids, simpler explanation, and treating reversible disturbance come first.

IMF-100-03-0014-en	Why is a signed consent form not the same as valid informed consent?	Valid consent requires relevant disclosure, comprehension, voluntariness, capacity, and an affirmative decision; the form is only evidence of that process, which can be withdrawn.

IMF-101-01-0009-en	What does a standard deviation describe, compared with a standard error?	Standard deviation describes variation among observations; standard error describes sampling variability of an estimator.

IMF-101-01-0010-en	Under the usual independent-sample mean model with unchanged population variance, how does quadrupling sample size affect standard error?	It halves standard error because standard error is proportional to one divided by the square root of sample size.

IMF-101-02-0001-en	What does a hypothesis test assess, and what can it not directly decide?	It asks whether observed data are sufficiently incompatible with a specified statistical model to challenge it; it does not decide whether a theory is true, an effect is clinically important, or bias is absent.

IMF-101-02-0002-en	Why is a p value not the probability that the null hypothesis is true?

IMF-101-02-0009-en	Why do many tests at a five per cent threshold require multiplicity control, and what do family-wise and false-discovery methods limit?	With many true nulls the chance of at least one false rejection rises; family-wise control limits the probability of any false rejection, false-discovery-rate methods the expected proportion among rejections.

IMF-101-02-0010-en	How can convincing p values arise without deliberate fabrication, and what distinguishes planned from exploratory work?	Choosing outcomes, time points, exclusions, transformations or models after seeing results exploits researcher degrees of freedom; prespecification, registration, time-stamped protocols and code separate planned work.

IMF-101-02-0011-en	Why is a significant result in one subgroup and a nonsignificant result in another not evidence that the effect differs?	Evidence that effects differ across patient characteristics requires a direct interaction test, not a comparison of separate significance labels.

IMF-101-02-0012-en	Why can bias toward similarity falsely support non-inferiority, and how is this usually checked?	Non-inferiority only requires excluding an unacceptable loss, so poor adherence or outcome misclassification that blurs differences favours the claim; intention-to-treat and per-protocol views are often both examined.

IMF-101-02-0013-en	Why does pooling systematically biased studies in a meta-analysis not yield a trustworthy estimate, however precise?	Meta-analysis is only as meaningful as the studies' estimands, bias and heterogeneity permit, so a precise pooled estimate from biased studies remains precisely wrong.

IMF-101-02-0014-en	Why does repeatedly checking accumulating data and stopping when significance appears distort the evidence?	It inflates false-positive probability unless the design accounts for it, and stopping early for benefit when few events have accrued can exaggerate the effect estimate.

IMF-101-03-0001-en	Why does adjusting a regression coefficient for other variables not make it causal?	Adding variables does not automatically remove bias; what each parameter means depends on the outcome scale, functional form, sampling process and variable timing.

IMF-101-03-0002-en	Why is categorising a continuous predictor usually inferior to splines, polynomials or transformations?	Categorising loses information, reduces power and creates threshold interpretations dependent on chosen cut points, whereas the alternatives represent curvature without arbitrary categories.

IMF-101-03-0003-en	Why can a model show no interaction on one scale yet interaction on another?	Interaction changes an additive effect in a linear model but the effect on that model's own scale in logistic or survival models, so absence on one scale does not imply absence on another.

IMF-101-03-0004-en	Why can logistic regression output exaggerate an effect, and what is often more interpretable?	Exponentiated coefficients are odds ratios, not risk ratios, and with common outcomes they exaggerate relative change; predicted probabilities are clearer but depend on intercept and covariate pattern.

IMF-101-03-0005-en	How can adjustment itself introduce bias into an estimated effect?	Adjusting for a consequence of exposure removes part of the effect, and adjusting for a common effect of two variables creates collider bias.

IMF-101-03-0006-en	Why can simple survival estimates be biased when sicker participants leave follow-up differently?	Standard methods usually assume censoring is conditionally independent of the event process, and differential loss of sicker participants violates that assumption.

IMF-101-03-0007-en	What does the Cox model assume, and what can communicate effects better when hazards vary or cross?	It leaves the baseline hazard's shape unspecified but assumes a hazard ratio constant over time; restricted mean survival time or time-specific absolute risks may then be clearer.

IMF-101-03-0008-en	How does treating competing deaths as censored differ in what it estimates from cumulative-incidence methods?	Censoring competing deaths estimates a hypothetical world where that event is removed, under strong assumptions; cumulative incidence estimates event probability in the observed world with competition.

IMF-101-03-0009-en	Why can a prediction model with good discrimination still be unsuitable for use?	Discrimination only shows that higher-risk people tend to have more events; calibration, agreement of predicted and observed risk, can still fail by systematic overprediction or in important subgroups.

IMF-101-03-0010-en	Why does choosing a threshold by maximising a generic index risk mismatching clinical practice?	It assumes false positives and false negatives have particular equal costs, and the ROC curve behind it ignores prevalence and the consequences of errors.

IMF-101-03-0011-en	Why must cross-validation or bootstrapping repeat the entire modelling process to estimate optimism?	A model learns sample-specific noise, so training performance is optimistic; optimism is estimated only when preprocessing and selection are also repeated within each resample.

IMF-101-03-0013-en	Why can a statistical test not establish whether data are missing at random or not at random?

IMF-102-01-0023-en	Why can turbidity invalidate a simple absorbance-to-concentration conversion?	Scattering contributes to loss of transmitted light, so the signal is not explained by absorption alone.

IMF-102-02-0001-en	Why must controls in molecular methods follow the whole chain from specimen to data, not just the final readout?	Extraction, amplification, labelling, sequencing and filtering each create a representation that can selectively lose or enrich material, so the signal may not match the molecule in the original specimen.

IMF-102-02-0002-en	What do extraction blanks and spike-in molecules each monitor, and why does the choice of extraction kit matter?	Blanks reveal reagent contamination and spike-ins monitor recovery; different kits can produce systematic differences that resemble biology.

IMF-102-02-0003-en	Why is end-point PCR poorly quantitative, and how does quantitative PCR estimate starting template instead?	After reagents saturate, accumulated product no longer tracks the starting amount; quantitative PCR monitors fluorescence during amplification and uses the threshold-crossing cycle, if efficiency and baseline handling are valid.

IMF-102-02-0005-en	Why might Sanger sequencing miss a variant carried by only a minority of the DNA molecules?	Sanger sequencing produces a consensus signal, so low-frequency variants can be missed; it remains useful for small regions and for confirmation.

IMF-102-02-0007-en	After genome editing produces a phenotype, how can target function be separated from editing artefact?	Rescue experiments or independent guides are required, because off-target editing, mosaicism, large rearrangements and p53-related selection can also accompany editing.

IMF-102-02-0008-en	Why can an apparent expression change in bulk RNA sequencing be ambiguous?	Bulk sequencing averages across cells, so the change may reflect altered expression within a cell type or a changed mixture of cell types.

IMF-102-02-0010-en	Why is identifying a feature in untargeted metabolomics uncertain, and what raises confidence?	One metabolite can yield several ions, adducts or fragments, and different molecules can share mass; confidence rises with accurate mass, retention, fragmentation and comparison with authentic standards.

IMF-102-02-0011-en	In single-cell RNA sequencing, why should dropout of a gene or a new cluster not be taken at face value?	Dropout reflects limited sampling rather than true absence, and clusters emerge from analytic choices, so they need markers, anatomy, function and independent validation.

IMF-102-02-0012-en	Why is pathway enrichment a hypothesis generator rather than evidence that a pathway is active?	Its result depends on the background gene set, database definitions and selection threshold; and using the same data to select and test a pattern is circular.

IMF-102-02-0013-en	Why can computational correction not rescue a study in which batch is confounded with disease group?	When batch and group coincide, technical and biological signal cannot be reliably separated; randomising samples across batches with bridge controls prevents more bias than later correction.

IMF-102-02-0014-en	Why does a molecular signature that classifies samples well not establish mechanism, and what builds strong inference?	A signature can classify without identifying mechanism; strong inference adds validation in independent material, localisation to relevant cells, perturbation in a suitable system and connection to human phenotype.

IMF-102-03-0001-en	Why are the cells in one treated culture dish subsamples rather than independent replicates?	The experimental unit is the smallest independently assigned entity, and the whole dish received the treatment; counting its cells as replicates creates pseudoreplication and false precision.

IMF-102-03-0003-en	Why should blinding be assessed rather than assumed, and does automated analysis remove the need for it?	Visible phenotypes or adverse effects can break blinding; automated analysis reduces some discretion but inherits thresholds and training choices made by people.

IMF-102-03-0005-en	What does a crossover design gain, what does it require, and what violates its assumptions?

IMF-102-03-0008-en	What distinguishes direct from conceptual replication, and when does a failure to reproduce demand investigation?	Direct replication repeats conditions; conceptual replication tests the same claim by another method.

IMF-102-03-0009-en	When is adjusting an image's brightness or contrast acceptable, and what makes image processing misrepresent evidence?	Uniform adjustment can be appropriate if it neither hides nor creates features and the original is kept; selective alteration, moving bands or combining fields without clear boundaries misrepresent evidence.

IMF-103-01-0007-en	Why is job title alone a poor measure of occupational exposure?	Exposure depends on task, schedule, control, protection, employment status, and cumulative history, which a title does not capture.

IMF-103-01-0008-en	Why should a clinician ask where a person lives before advising rest, refrigeration, wound hygiene, or isolation?	Housing instability disrupts medicine storage and follow-up, so a plan made without asking can be medically correct but impossible to carry out.

IMF-103-01-0012-en	What distinguishes isolation from loneliness?	Isolation is an objective lack of contact, whereas loneliness is a perceived mismatch between desired and actual connection, so crowded households can be lonely and living alone need not be.

IMF-103-01-0014-en	Why is substituting broad race categories for genotype, environment, or lived experience a scientific error?	Racism is not a biological property of racialised groups; its biological consequences arise through unequal treatment and exposure, so broad categories cannot stand in for those variables.

IMF-103-01-0017-en	Why can regulation of commercial determinants act powerfully, and what should it anticipate?	Individual choice occurs within engineered environments, so regulation can change defaults and exposure at scale, but it should anticipate substitution, illicit markets, regressive costs, and industry adaptation.

IMF-103-01-0019-en	What does the inverse care law describe, and why can equal appointment length be inequitable?	Good care tends to be least available where need is greatest, especially under market forces; equal time is inequitable when complexity differs.

IMF-103-01-0021-en	What distinguishes a high-risk prevention strategy from a population strategy?	A high-risk strategy gives large benefit to few people but depends on detection and continued engagement; a population strategy shifts the whole distribution, giving many small benefits and addressing causes of incidence.

IMF-103-01-0023-en	Why can absolute and relative measures of inequity give conflicting pictures?	Absolute differences show event-rate gaps and relative differences show proportional disparity, and the two can move in opposite directions as overall rates change.

IMF-103-01-0024-en	Why are social determinants not an excuse for therapeutic pessimism, and how do clinical and policy action relate?	They are causal candidates: clinicians can identify barriers, adapt treatment, document needs with consent, and connect services, while policy acts upstream; neither level substitutes for the other.

IMF-103-02-0002-en	Why can a nominal entitlement fail to deliver universal health coverage?	Informal fees, medicine shortages, waiting, or poor quality can coexist with it, and promising services without workforce or supply creates queues and inequitable private escape.

IMF-103-02-0003-en	Why do small fragmented risk pools and out-of-pocket payment undermine financial protection?	Fragmented pools weaken redistribution and create incentives to select low-risk members, while payment at illness onset exposes households to catastrophic expenditure and deters high-value care.

IMF-103-02-0004-en	How does adverse selection destabilise voluntary insurance pools, and what are the limits of risk adjustment?

IMF-103-02-0006-en	How do the incentives of fee-for-service and capitation differ?	Fee-for-service rewards each activity, encouraging volume and fragmentation; capitation pays per enrolled person, promoting prevention and cost control but risking risk selection or under-service.

IMF-103-02-0008-en	How is an incremental cost-effectiveness ratio calculated, and why can it be unstable?	It divides the difference in costs by the difference in effects between options; when differences are small the ratio is unstable, so uncertainty is better shown as probabilities across thresholds.

IMF-103-02-0009-en	How can a cost-effective intervention still be unaffordable, and a beneficial technology reduce total health?	Budget impact asks whether a payer can afford adoption at scale, which differs from cost-effectiveness; a technology that helps recipients can displace more effective care elsewhere.

IMF-103-03-0009-en	What does fidelity preserve, and what is the key challenge in adapting an intervention?	Fidelity preserves the intervention's core causal functions rather than every surface detail; the challenge is distinguishing function-preserving adaptation from removal of the active component.

IMF-103-03-0010-en	Which assumption does difference-in-differences rely on, and what does interrupted time series require?	Difference-in-differences assumes parallel trends between exposed and comparison groups; interrupted time series needs enough observations and attention to concurrent events.

IMF-103-03-0011-en	How can a programme improve participants' outcomes yet widen population inequity?	Disadvantaged people may be less likely to enrol or remain, which is why the product of reach and effectiveness can matter more than either alone.

IMF-103-03-0012-en	What distinguishes vertical, horizontal, and diagonal approaches to health investment?	Vertical programmes focus on one condition for rapid measurable results, horizontal investment strengthens broad systems, and diagonal approaches use focused priorities to build shared capacity.

IMF-103-03-0013-en	Why can removing single-use items or travel for decarbonisation transfer risk, and what does life-cycle assessment add?	Removing clinically valuable items or travel without safe alternatives shifts risk rather than removing it; life-cycle assessment considers production, use, and disposal, not visible waste alone.

IMF-103-03-0014-en	Why is precautionary regulation of pollution not evidence-free prohibition?	Acting before every causal pathway is proven is justified when exposure is widespread and delayed harm may be irreversible, and precaution combines plausible hazard, exposure, alternatives, uncertainty, and consequence.

IMF-104-01-0001-en	Why can maximal oxygen uptake not explain every form of exercise performance?	It summarises important capacity, but the limiting process changes with intensity, duration, environment, training, health, and motivation, so no single measure captures every limit.

IMF-104-01-0002-en	Intramuscular ATP sustains maximal contraction for only seconds. How does phosphocreatine protect energy supply at the abrupt onset of intense work?	Through creatine kinase it rapidly donates phosphate to ADP, regenerating ATP and buffering energy during sudden demand.

IMF-104-01-0003-en	What does reducing pyruvate to lactate accomplish during anaerobic glycolysis?	It regenerates oxidised nicotinamide cofactor, allowing glycolysis to keep producing ATP rapidly from glucose or glycogen.

IMF-104-01-0004-en	Why is it misleading to describe the energy systems as switching on one after another during exercise?	They operate simultaneously with shifting contributions: a sprint has high phosphagen and glycolytic flux while oxidative metabolism rises rapidly, and prolonged moderate exercise still uses glycolysis.

IMF-104-01-0005-en	Why does lactate production during exercise not indicate that muscle lacks oxygen?	Lactate reflects glycolytic flux and redox balance, and it is a usable fuel that muscle and heart oxidise or the liver uses for glucose production.

IMF-104-01-0006-en	How does stroke volume change with rising dynamic exercise intensity, and how can endurance-trained people differ?	It rises through filling and contractility and often approaches a plateau, whereas endurance-trained people may keep increasing it at high intensity.

IMF-104-01-0007-en	How can active muscle receive more blood when sympathetic outflow is high during exercise?	Local mediators such as adenosine, potassium, carbon dioxide, and hydrogen ions oppose vasoconstriction in active muscle (functional sympatholysis), while less active beds still constrict.

IMF-104-01-0009-en	Why can heavy resistance exercise transiently produce very high blood pressure, and what does this not imply?	Contracting muscle compresses vessels and raises resistance, amplified by breath holding and the Valsalva manoeuvre; the acute rise does not mean resistance training inevitably causes chronic hypertension.

IMF-104-01-0010-en	Why does ventilation rise disproportionately beyond the ventilatory threshold?	Bicarbonate buffering of accumulating hydrogen ions generates additional carbon dioxide, and neural drive also rises.

IMF-104-01-0011-en	What drives the immediate rise in ventilation at exercise onset, and what happens to arterial gases during moderate steady exercise in healthy people?	Central command and sensory feedback raise ventilation at once; ventilation then tracks carbon dioxide production, so arterial oxygen and carbon dioxide pressures stay near normal despite much larger gas exchange.

IMF-104-01-0012-en	By what mechanisms can exercise-induced arterial desaturation occur despite the lung's usual reserve?	Red-cell transit through the capillaries becomes short, ventilation-perfusion matching is imperfect, or diffusion is limited, as exposed by elite endurance demand, altitude, or lung or heart disease.

IMF-104-01-0013-en	Why does anaemia require a higher cardiac output for the same oxygen delivery even when saturation is normal?	Arterial oxygen content depends mainly on haemoglobin concentration and saturation, with little dissolved in plasma, so low haemoglobin lowers content per unit of blood.

IMF-104-01-0014-en	How do conditions in active muscle help haemoglobin release oxygen where it is needed?	Increased temperature, carbon dioxide, and acidity lower haemoglobin affinity, facilitating unloading in active tissue, while conditions in the lung support reloading.

IMF-104-01-0015-en	Why can extra mitochondria not fully compensate for severely limited muscle blood flow?	Oxygen delivery and utilisation are interdependent: mitochondria cannot use oxygen that is not delivered, just as high flow cannot make oxidative ATP without functional mitochondria.

IMF-104-01-0016-en	In what order are motor units generally recruited as force rises, and what can alter that order?	Lower-threshold fatigue-resistant units come first, then larger faster units; rapid ballistic tasks, electrical stimulation, injury, and specialised movement can modify the order.

IMF-104-01-0017-en	Why does carbohydrate use generally increase as exercise intensity rises?	Carbohydrate supplies ATP faster and more efficiently per unit oxygen than fat, and rapid ATP demand plus recruitment of more fibres favour glycolysis.

IMF-104-01-0018-en	Insulin concentration often falls during exercise. How does muscle glucose uptake still rise, and what maintains blood glucose?	Contraction-dependent transporter movement increases muscle glucose uptake independently of insulin, while glucagon and catecholamines support hepatic glucose output.

IMF-104-01-0019-en	Why does the same absolute workload provoke a smaller hormonal stress response after training?	Hormonal responses are graded by relative intensity, and training raises capacity so the same workload becomes a lower relative demand.

IMF-104-01-0021-en	How does exercise economy differ from maximal oxygen uptake, and how can it improve?	Economy is the oxygen or energy cost at a given submaximal speed or power; it can improve through technique and elastic energy storage without any change in maximal oxygen uptake.

IMF-104-01-0022-en	What does the effect of deception about time or distance on output show about how performance is regulated?	Performance is regulated by both physiological state and information, because pacing reflects learned predictions about remaining distance and capacity.

IMF-104-01-0023-en	What distinguishes peripheral from central fatigue within a single bout, and why is neither the whole explanation?	Peripheral fatigue involves metabolites, excitation-contraction coupling, ion shifts, substrate depletion, and damage; central fatigue is reduced effective neural drive. They interact as safety and performance processes.

IMF-104-01-0024-en	Why can submaximal thresholds in exercise testing be more informative than a single peak value?	A peak may be limited by symptoms or protocol before a physiological maximum is reached, whereas thresholds and response patterns help locate cardiac, pulmonary, vascular, muscular, or motivational constraints.

IMF-104-02-0001-en	Why is more training work not automatically better for adaptation?	Adaptation depends on the balance between the training signal and recoverable cost; the stimulus must exceed accustomed demand, but recovery must permit remodelling.

IMF-104-02-0009-en	Is interference between concurrent endurance and resistance training an absolute molecular prohibition? How should it be managed?	No; it depends on total load, modality, nutrition, training status, and session proximity. Place the priority quality when fatigue is lowest and allow enough recovery for its adaptation.

IMF-104-02-0010-en	Why is monitoring only external or only internal training load misleading?	The same external load creates different internal stress with heat, illness, sleep loss, altitude, or improved fitness, so one alone can mistake declining capacity for increased effort or fitness for undertraining.

IMF-104-02-0013-en	Why can a normal heart rate after training not be taken as evidence of complete recovery?	Different systems recover on different timescales, so heart rate may normalise while glycogen remains low, or soreness may persist after force returns.

IMF-104-03-0001-en	Why does high humidity reduce evaporative cooling even though sweat is produced?	Evaporation cools only if sweat reaches the skin and vapour pressure permits it; with high humidity, sweat drips unevaporated and removes little heat.

IMF-104-03-0002-en	Why does heart rate rise during prolonged exercise in the heat?	Skin blood flow competes with active muscle and central blood volume, and sweating reduces plasma volume, so stroke volume can fall and heart rate rises.

IMF-104-03-0004-en	What feature distinguishes heat stroke from heat exhaustion, and why does continued sweating not exclude it?	Heat stroke combines dangerous hyperthermia with central nervous system dysfunction; normal-looking skin or ongoing sweating does not rule it out, so rapid cooling should not wait.

IMF-104-03-0009-en	Why is the initial hypoxic ventilatory response at altitude restrained, and how is sustained hyperventilation permitted over days?	Hyperventilation lowers carbon dioxide and causes respiratory alkalosis, which restrains further ventilation; over days the kidney excretes bicarbonate, allowing sustained hyperventilation.

IMF-105-02-0007-en	Under the same solvent and temperature conditions, what does a lower pKa indicate?	A stronger acid, meaning greater dissociation tendency; it does not specify how concentrated the solution is.
