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.	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-063-01-0002-en	Why is pregnancy testing part of the first assessment of undifferentiated acute illness?	A positive or negative result can alter almost every acute differential.

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.	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-063-01-0004-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.	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-063-01-0005-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.	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-063-01-0006-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.	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-063-01-0007-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.	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-063-01-0008-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.	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-063-01-0009-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.	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-063-01-0010-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.	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-063-01-0012-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.	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-063-01-0013-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.	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-063-01-0014-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.	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-063-01-0015-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.	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-063-01-0016-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.	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-063-01-0017-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.	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-063-01-0019-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.	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-063-01-0020-en	What distinguishes weakness, fatigue, and sleepiness?	Weakness is reduced force, fatigue is difficulty sustaining activity or low energy, and sleepiness is a propensity to sleep.	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-063-01-0021-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.	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-063-01-0022-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.	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-063-01-0023-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.	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-063-01-0024-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.	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
