Which of the following temperatures indicates severe hypothermia?

Severe hypothermia is classified as a critical condition where the body's core temperature falls below a certain threshold, which is typically recognized as being less than 90°F. At this temperature, the body's normal physiological functions are significantly impaired, potentially leading to a variety of serious complications.

In this state of severe hypothermia, the risk of cardiac arrhythmias, decreased mental status, loss of consciousness, and other life-threatening conditions is greatly increased. Understanding this classification is essential for proper assessment and medical intervention in scenarios where hypothermia might be present.

While the other temperature ranges mentioned (92°F, between 90°F and 95°F, and 80°F) do indicate lower body temperatures, they do not meet the specific criteria that define severe hypothermia. Temperatures 92°F and higher are generally considered mild to moderate hypothermia, and while 80°F is critically low, it is encompassed within the less than 90°F classification for severe hypothermia.
