For heat stroke management, which cooling method is described?

• A. Move the patient into the back of the rescue as soon as possible.
• B. Decrease the air-conditioning temperature in the patient’s compartment.
• C. Normal saline infusion alone is sufficient.
• D. Mist the patient with cold water and use fan or convection.

Answer: (D)

Rapid cooling is the priority in heat stroke, and evaporative cooling is one of the fastest field methods to achieve it. Spraying cold water on the skin while circulating air with a fan increases evaporation, which pulls heat away from the body quickly and effectively lowers core temperature. This approach works well in outdoor or emergency settings where other cooling methods may be too slow or impractical.

Moving the patient to a different location inside a rescue, or just relying on a cooler environment in the vehicle, doesn't guarantee rapid cooling and can delay treatment. Lowering the air-conditioning temperature in the compartment may help slightly, but it’s not a rapid, reliable method for abrupt cooling in a hot crisis. Hydration with saline is important, but infusing fluids alone without actively cooling the body won’t address the immediate danger of overheating.

So, misting with cold water and using a fan or convection maximizes heat loss through evaporation and is the best described cooling method in this scenario.
