In exertional heat stroke management, what is the primary cooling goal and sequence of actions?

• A. Lower body temperature below 102°F within 30 minutes; remove equipment in the tub; assess vital signs every 5–10 minutes; use cooling with water at 35–59°F and sip continuously; COOL first, TRANSPORT second; document CWI policy in EAP
• B. Warm the patient to prevent shivering and transport immediately
• C. Delay cooling until transportation arrives
• D. Use dry heat packs to extremities and leave the patient undisturbed

Answer: (A)

Rapid cooling is the priority in exertional heat stroke, because bringing the core temperature down quickly reduces the risk of organ damage and death. The best approach targets lowering the core temperature to below 39°C (102°F) within about 30 minutes of collapse, using the fastest effective method available. Whole-body cold water immersion is the most efficient way to achieve rapid cooling. Submerging the person in water that is very cold (roughly 35–59°F or 2–15°C) maximizes heat transfer from the body. As you start cooling, remove any equipment and restrictive clothing to maximize contact with the cold water and improve heat loss. While cooling proceeds, monitor vitals at regular intervals—every 5–10 minutes—to detect any deterioration and to guide ongoing care. Do not wait for transport to begin cooling; the sequence is to cool first and transport second, continuing cooling as feasible during transfer. If the person is awake and able to swallow, offering sips of fluid can support hydration, but this is secondary to cooling and should not delay immersion. Documentation of the cooling protocol in the emergency action plan ensures all responders follow the same steps and policies. Other choices miss the central point: warming the patient or delaying cooling worsens outcomes, dry heat packs are ineffective for rapid cooling, and leaving the patient undisturbed prevents the critical cooling from happening promptly.
