What are common signs of hypothermia?

Choosing the signs of hypothermia involves recognizing the body's responses to cold exposure. Hypothermia occurs when the body's temperature drops below the normal range, and the common signs often include shivering, confusion, and fatigue.

Shivering is the body's initial response to help generate heat. It is an involuntary muscular reaction aimed at increasing body temperature. As hypothermia progresses, other cognitive signs like confusion can arise, as reduced body temperature affects brain function and decision-making abilities. Fatigue accompanies these symptoms since the body struggles to maintain energy levels while trying to cope with the cold stress.

In contrast, the other options present signs that do not accurately reflect the physiological responses associated with hypothermia. Increased heart rate and sweating might be expected in heat-related issues rather than hypothermia. The combination of excessive thirst, rapid breathing, and dizziness suggests dehydration or heat exhaustion. Lastly, high fever, nausea, and vomiting point towards an infection or illness rather than a cold-induced condition like hypothermia. Therefore, B accurately captures the critical symptoms to recognize when dealing with hypothermia.
