Heat Stroke is described as the condition that occurs when the body loses the ability to heat itself back up.

• A. Concussion
• B. Heat Stroke
• C. Hypothermia
• D. Strains

Answer: (B)

Heat stroke happens when the body's cooling mechanisms fail and the core temperature rises to dangerous levels, typically above 40°C (104°F). It’s a medical emergency because high temperature can quickly damage the brain and other organs. The essential point is that heat stroke is about losing the ability to cool down, not about heating up. That’s why rapid cooling and urgent medical care are needed. Signs include confusion or agitation, seizures, loss of consciousness, very hot and often dry skin, and a rapid heartbeat. The other options describe different problems: a concussion is a head injury, hypothermia is a dangerous drop in body temperature from cold exposure, and strains are muscle or tendon injuries. So this scenario centers on a failure to cool, which is why heat stroke is the correct concept.
