Pyrexia is another term for which condition?

• A. Hypothermia
• B. Feverish Condition
• C. Heat Stroke
• D. Fever

Answer: (D)

Pyrexia is the medical term for a fever. It describes an elevated body temperature that occurs when the body raises its thermostat in the hypothalamus in response to infection or inflammation. This is a regulated change, meaning the body actively sets a higher temperature to help fight off illness.

That makes fever the best answer because pyrexia and fever refer to the same clinical state. The other options describe different temperature problems: hypothermia is a lowered body temperature, heat stroke is an extreme, non-regulated rise in temperature due to environmental heat, and a “feverish condition” is a lay term that isn’t the precise medical term for the process.
