How should heat-related illness be managed in the field?

• A. Move to a cooler environment, remove excess clothing, hydrate if possible, apply cooling measures, monitor vitals, transport.
• B. Keep patient in heat to induce sweating.
• C. Give hot beverages to stimulate sweating.
• D. Apply icy water to skin without monitoring.

Answer: (A)

Managing heat-related illness in the field hinges on removing the person from heat and promoting heat loss as quickly as possible, while supporting fluids, cooling, and ongoing monitoring. Move the person to a cooler environment and loosen or remove excess clothing to help heat escape. If the person is alert and able to swallow, offer fluids to replace what’s been lost through sweating and to help prevent dehydration. Apply cooling measures as soon as you can—use shade, air movement, wet towels, or fans, and apply cold packs to areas like the neck, armpits, or groin; in a suspected heat stroke, more rapid cooling (such as cold-water immersion) is ideal when safe and feasible. Keep a close eye on vital signs and responsiveness, and arrange prompt transport to medical care.

The other options would worsen the situation: staying in the heat to induce sweating doesn’t promote cooling; hot beverages add heat and fluid loss to the body; applying icy water to the skin without monitoring can cause shivering or cold injuries and misses signs of deterioration.
