Which of the following best describes a symptom of severe hypothermia?

Severe hypothermia occurs when the body loses heat faster than it can produce it, leading to dangerously low body temperatures. One of the hallmark symptoms associated with severe hypothermia is confusion and drowsiness. As the body's temperature drops, metabolic processes slow down, which can significantly impair cognitive function and lead to altered mental states.

Individuals may appear disoriented, have difficulties concentrating, or exhibit irrational behavior. Drowsiness often sets in as the body attempts to conserve energy, and the individual may become unresponsive or lethargic. Recognizing these signs is crucial for initiating prompt treatment, as hypothermia can rapidly become life-threatening.

In contrast, other options describe symptoms that are characteristic of different conditions or less severe stages of hypothermia. For instance, increased heart rate is more commonly associated with mild hypothermia or other medical conditions, while shivering typically occurs in the early stages as the body attempts to generate heat. Red and warm skin can signal overheating or conditions like heat exhaustion, which are not relevant to hypothermia.
