Reveal the answer and explanation

Correct answer: C — Withhold adrenaline and limit to 3 shocks until core temp ≥30°C

Hypothermic arrest <30°C: attempt defib but if VF/pVT persists after 3 shocks, withhold further shocks and IV drugs until rewarmed >30°C. Myocardium refractory below 30°C. Active rewarming priority. 'No one dead until warm and dead.'
