Which of the following best describes hypothermia?

Hypothermia is best described as a cold-related health condition, which occurs when the body's core temperature drops significantly below the normal range, typically below 95°F (35°C). This condition can happen when an individual is exposed to cold temperatures for extended periods, often combined with wind, wetness, or inadequate clothing. Symptoms of hypothermia can include shivering, confusion, exhaustion, and in severe cases, loss of consciousness. This makes option B the appropriate choice, as it directly addresses the core characteristic of hypothermia and its relationship with cold environments.

The other options do not accurately reflect the nature of hypothermia. For example, a state of excessive heat pertains to hyperthermia or heat-related illnesses. An injury from falling relates to trauma rather than temperature regulation issues. A chronic lung condition would refer to diseases such as asthma or COPD, which are neither related to temperature extremes nor fall under the category of hypothermia. Thus, the chosen description effectively encapsulates the essence of the condition.
