What is the appropriate initial management for heat exhaustion?

• A. Apply ice packs to the groin and armpits
• B. Move to a cooler environment and give oral fluids if tolerated
• C. Induce vomiting to prevent dehydration
• D. Give intravenous fluids only in the hospital

Answer: (B)

The key idea is to quickly reduce heat buildup and restore fluid balance when someone has heat exhaustion. The best initial move is to move the person to a cooler environment and offer oral fluids if they can swallow. This addresses both excess body heat and dehydration without delaying care. Providing fluids helps replace lost water and electrolytes, supports mental status, and can prevent progression to more serious heat illness. Remove restrictive clothing, fan or cool the area, and encourage sips of water or an electrolyte solution as tolerated.

Why the other options aren’t ideal initially: applying ice packs to the groin and armpits focuses cooling only on small areas and can be uncomfortable; it isn’t the most effective first step for whole-body heat relief and can provoke shivering, which counteracts cooling. Inducing vomiting has no benefit for heat exhaustion and risks aspiration. Giving intravenous fluids should be reserved for cases where the patient cannot take fluids by mouth, is severely dehydrated, or symptoms worsen; the initial approach for heat exhaustion is oral fluids and environmental cooling, with escalation to IV therapy only if needed in a clinical setting.
