Correct answer: AHandle the patient gently, insulate and rewarm, avoiding rough movement that could trigger an arrhythmia.

In severe hypothermia the cold myocardium is irritable, so the patient is handled gently and rewarmed in a controlled way, with core rewarming favoured and rough handling avoided to prevent ventricular fibrillation. Vigorous rubbing and peripheral rewarming can cause an afterdrop and arrhythmia. Alcohol causes vasodilatation and further heat loss.
