Which core temperature indicates heat stroke?

Which core temperature indicates heat stroke?

• A. 98.6 F
• B. 104 F
• C. 102 F
• D. 107 F

Answer: (B)

Heat stroke happens when the body's cooling system fails and the core temperature rises to about 104 F (40 C) or higher, usually with signs of brain involvement such as confusion or altered consciousness. Among the options, 98.6 F is normal, 102 F is elevated but not at the threshold for heat stroke, and 107 F is extremely high and dangerous. The defining threshold used to indicate heat stroke is 104 F, especially when accompanied by neurologic symptoms, which is why that temperature is the best answer. Heat stroke is a medical emergency and requires rapid cooling and medical attention.
