What core temperature defines heat stroke?

What core temperature defines heat stroke?

• A. Core temperature > 38 C
• B. Core temperature > 39 C
• C. Core temperature > 41 C
• D. Core temperature > 40 C

Answer: (C)

Heat stroke is defined by severe hyperthermia accompanied by central nervous system dysfunction. While any core temperature above 40°C is a warning sign, exam practice often uses a threshold around 41°C to classify heat stroke, because this level of temperature with CNS impairment clearly indicates a life-threatening hyperthermic state. So the best match among the options is the temperature above 41°C. Keep in mind that the crucial factor isn't the exact number alone, but the combination of very high core temperature with altered mental status; urgent rapid cooling and supportive care are essential once heat stroke is suspected.
