Which intervention is used to rapidly reduce core temperature in heat stroke?

• A. Rewarming
• B. Active Cooling
• C. Frostbite Care
• D. Hypothermia Induction

Answer: (B)

In heat stroke, the top priority is to remove the excess heat from the body as quickly as possible, because the high core temperature can cause rapid organ failure. The method that achieves this fastest is active cooling—external techniques that actively transfer heat away from the body. Cold water immersion (often ice water) is the most effective approach, since water conducts heat much more efficiently than air and can markedly lower core temperature within minutes. Other active cooling options include cooling blankets, ice packs placed in the groin and armpits, and evaporative cooling with mist and fans. Relying on passive cooling or simply removing from the heat would take too long and risks ongoing damage. Frostbite care is unrelated to heat stroke, and deliberately inducing hypothermia is not appropriate in this scenario.
