How should heat-related illnesses be identified and managed in lifeguard care?

• A. Ignore symptoms and continue monitoring only.
• B. Increase physical activity to generate heat.
• C. Apply ice directly to skin and avoid hydration.
• D. Recognize symptoms of heat exhaustion or heat stroke; move to shade, remove excess clothing, hydrate, and call EMS if heat stroke suspected.

Answer: (D)

Recognizing and treating heat-related illness promptly is essential in lifeguard care because these conditions can escalate quickly from heat exhaustion to heat stroke, which is life-threatening if not acted on fast. The best approach is to identify warning signs and respond with cooling, hydration, and escalation as needed. Move the person to shade and remove excess clothing to help dissipate heat. If they are awake and able to swallow, offer fluids to rehydrate. Monitor consciousness and breathing closely. If heat stroke is suspected—such as very high fever, confusion, or unconsciousness, or hot, dry skin—call EMS immediately and begin rapid cooling while awaiting help. Avoid ignoring symptoms, overexertion, or attempting to generate more heat. Do not apply ice directly to the skin or withhold hydration; these steps can worsen the situation. The goal is quick recognition, cooling and hydration, and urgent medical assistance when heat stroke is likely.
