When encountering a person showing signs of heat exhaustion, which of the following actions is most appropriate?

When encountering a person showing signs of heat exhaustion, encouraging them to cool off and hydrate is the most appropriate action. This condition occurs when the body becomes overheated due to prolonged exposure to high temperatures, often combined with dehydration.

Cooling off is vital because it helps lower the person's body temperature, preventing the progression to more severe heat-related illnesses such as heat stroke. Hydration is equally important since heat exhaustion is often accompanied by fluid loss through sweating. Providing fluids, preferably water or electrolyte drinks, aids in replenishing lost fluids and supports the body's natural cooling mechanisms.

This option effectively addresses both the immediate needs of the person and the underlying causes of their symptoms, making it a comprehensive approach to managing heat exhaustion. It promotes recovery and ensures that individuals receive the care they need to safely return to normal activities.
