Questions Covered in This Set
12 cards to master
What are the five reusable shapes of physiology exam questions?
1) Directional perturbation (X↑, what happens to Y?), 2) Graph/curve manipulation, 3) Two-mechanism discrimination, 4) Calculation, 5) Localisation.
A pure α1 agonist is given — what happens to heart rate and why?
Reflex bradycardia: ↑TPR → ↑MAP → ↑baroreceptor firing → ↑vagal outflow, despite no direct cardiac drug effect.
What is the general recipe for solving a 'directional perturbation' question?
Identify the negative feedback loop, mark the one direct drug/insult effect, then follow the arrows around the loop.
How should you study two-mechanism discrimination topics (e.g. central vs nephrogenic DI)?
Memorise the single discriminating test, not the entire comparison table.
Name the core physiology formulas worth owning cold.
Fick cardiac output, clearance and filtration fraction, alveolar gas equation, anion gap, Henderson–Hasselbalch, free water deficit (~10 formulas total).
Why does a large pulmonary embolus give a near-normal PaCO₂ but raised A–a gradient?
Hyperventilation of perfused alveoli clears CO₂ (highly diffusible/soluble), but V/Q mismatch and dead space impair oxygenation, widening the A–a gradient.
Right-sided spinal hemisection at T10: what pattern results?
Ipsilateral loss of vibration/proprioception below the lesion, contralateral loss of pain/temperature a couple of segments below, and ipsilateral spastic weakness.
Loss of pain on the left face and right body — where is the lesion?
Left lateral brainstem (medulla) — damaging the ipsilateral spinal trigeminal tract (left face) and the ascending spinothalamic tract carrying contralateral body sensation (right body).
In septic shock, why is lactate raised despite a high cardiac output?
Delivery is high but extraction/utilisation fails — microvascular shunting and mitochondrial dysfunction mean tissues cannot extract O₂, so anaerobic metabolism raises lactate.
Why does retrieval practice beat rereading?
Testing yourself yields roughly double the long-term retention of rereading for the same time invested — so convert weak spots into questions, not highlights.
What makes a good physiology flashcard versus a bad one?
Bad: shallow recall ('loop diuretic — mechanism?'). Good: mechanism-and-consequence reasoning that forces you to trace a causal chain.
NKCC (Na⁺/K⁺/2Cl⁻) blockade: predicted effects?
↑urine volume, ↑urine K⁺, metabolic alkalosis, ↑calcium excretion, and loss of the medullary osmotic gradient (impaired concentrating ability).
