For suspected heat stroke in the field, what is the immediate priority?

• A. Move to sunlight to dry
• B. Immediate rapid cooling with cool water immersion
• C. Call for help only
• D. Administer antipyretics

Answer: (B)

Rapid cooling is the immediate priority because heat stroke causes rapid brain and organ injury from overheating. The fastest, most effective way to reverse this process in the field is to actively cool the body, with cool water immersion directly removing heat from the tissues and lowering core temperature quickly. Antipyretics won’t help because heat stroke isn’t a fever; the body is failing to dissipate heat, not producing a fever response. Delaying cooling or simply calling for help without addressing the overheating lets damage progress, and moving into sunlight would hinder cooling. After starting cooling, summon advanced medical help and continue monitoring.
