What is hyperthermia?

Hyperthermia is defined as an abnormally high body temperature that occurs when the body's thermoregulation fails, leading to an inability to dissipate heat effectively. This condition can arise from various factors such as excessive heat exposure, intense physical exertion in hot environments, or certain medical conditions that impair the body's heat loss mechanisms.

When hyperthermia occurs, the body's core temperature rises above the normal range (generally considered to be around 98.6°F or 37°C), which can lead to serious health risks, including heat exhaustion, heat cramps, or heat stroke. Monitoring and understanding this condition is crucial for effective patient care, particularly in settings where individuals may be exposed to high temperatures or engage in vigorous activities.

As for the other choices, they do not accurately represent hyperthermia: an abnormally low body temperature indicates hypothermia, normal body temperature refers to a healthy physiological state, and a consistent pulse rate pertains to heart rate rather than body temperature. Understanding these distinctions is key in the assessment of vital signs and overall patient health.
