Abnormally low body temperature is?

• A. Tachycardia
• B. Stridor
• C. Crackles
• D. Hypothermia

Answer: (D)

Abnormally low body temperature is hypothermia. Core temperature below 35°C (95°F) defines this condition, with normal body temperature generally around 36.5–37.5°C. Hypothermia happens when heat loss exceeds heat production, often due to cold exposure or medical issues that impair warming. In clinical assessment, you’d look for signs such as shivering, slowed movements or speech, confusion, and, as it progresses, cardiovascular and respiratory changes. The other terms describe different body system findings: a rapid heart rate, a high-pitched breathing sound from an airway problem, and abnormal lung sounds from fluid or other lung issues. Only hypothermia directly refers to a low body temperature. Management focuses on rewarming and careful monitoring of vitals and core temperature.
