Which of the following describes common signs of hypothermia?

• A. Early shivering, later confusion, slurred speech, clumsiness, drowsiness, and slowed breathing.
• B. Increased heart rate and sweating.
• C. Headache and fever.
• D. Nausea and dehydration.

Answer: (A)

The signs of hypothermia show a clear progression from the body's attempt to generate heat to the brain and body slowing down as cooling worsens. Early shivering is a normal response when the body’s temperature drops, trying to produce warmth. As cooling continues, the brain is affected, leading to confusion, slurred speech, and poor coordination. This can quickly become more pronounced, with increasing drowsiness and a weakening ability to think clearly or move normally. In the most advanced stage, breathing slows, which increases the risk of further complications. This sequence—shivering first, then mental and motor decline, then slower breathing—fits hypothermia very well.

The other options describe signs that are not typical of hypothermia. Increased heart rate and sweating are more associated with heat-related problems, fever and headache point to infections or heat illnesses, and nausea with dehydration can occur with many conditions but doesn’t capture the characteristic progression of hypothermia.
