Both heat exhaustion and heat stroke are immediate life-threatening conditions.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (B)

The main idea here is understanding the difference in severity and urgency between heat stroke and heat exhaustion. Heat stroke is an emergency and can be immediately life-threatening because it involves a dangerously high core temperature and CNS dysfunction. Immediate action is required to cool the person rapidly and call for medical help. Signs include a body temperature of 104°F (40°C) or higher, confusion or unconsciousness, seizures, and very rapid or irregular breathing. Treatment focuses on rapid cooling (evaporative cooling with water and fans, ice packs in the groin, armpits, and neck) and emergency medical care.

Heat exhaustion, while serious and painful, is not typically an immediate life-threatening crisis. It presents with symptoms like heavy sweating, weakness, dizziness, nausea, clammy skin, and a fast but normal-to-slow pulse. The priority is to move the person to a cooler environment, loosen clothing, replace fluids with water or electrolyte drinks, and let them rest. If symptoms worsen or do not improve, or if confusion or fainting develops, it can progress toward heat stroke, which then becomes an emergency.

So the statement is false because heat exhaustion is not usually an immediate life-threatening condition, whereas heat stroke is.
