D
Shivering stops
Verified step by step guidance1
Understand the concept of hypothermia: Hypothermia occurs when the body loses heat faster than it can produce it, leading to a dangerously low body temperature. Severe hypothermia is characterized by critical physiological changes.
Learn the progression of hypothermia symptoms: In mild hypothermia, symptoms include shivering, confusion, and increased heart rate as the body tries to generate heat. As hypothermia worsens, these responses diminish.
Recognize the signs of severe hypothermia: In severe cases, the body's ability to shiver stops because the muscles are too cold to contract effectively. This is a critical sign that the body is losing its ability to regulate temperature.
Compare the options provided: Warm, flushed skin is not a sign of hypothermia; it is more associated with fever or heat-related conditions. Mild confusion and increased heart rate are signs of mild hypothermia, not severe hypothermia.
Conclude that the correct answer is 'Shivering stops,' as this is a hallmark sign of severe hypothermia indicating the body's inability to generate heat effectively.
