Which statement correctly identifies heat stroke?

• A. Heat cramps are the most severe form.
• B. Heat exhaustion is the stage before heat stroke.
• C. Heat stroke can be managed at home.
• D. Heat stroke: no sweating, confusion, high body temperature.

Answer: (D)

Heat stroke is a life-threatening heat illness in which the body’s cooling mechanisms fail, causing the core temperature to soar and mental status to be altered. The combination of a very high body temperature and confusion or other changes in thinking is a classic sign that requires urgent care. The statement matches this pattern by noting no sweating, confusion, and a high body temperature, which together indicate the body's cooling system has broken down. Heat cramps are simply muscle spasms from heat and dehydration and are not the most severe form of heat illness. Heat exhaustion is a distinct, less severe condition that can progress toward heat stroke, but saying it is necessarily the stage before heat stroke is imprecise. Heat stroke is a medical emergency and cannot be managed safely at home; it requires rapid cooling and professional medical help.
