The EMT is caring for a patient with mild hypothermia. Which clinical manifestation should the EMT expect to find?

In the case of mild hypothermia, piloerection is a common physiological response. This is when small muscles at the base of hair follicles contract, causing the hair to stand upright, commonly known as "goosebumps." This response can help to generate a small amount of heat by creating an insulating layer of air.

Piloerection is a natural mechanism the body uses to try to maintain its core temperature when it starts to drop. Although not extremely effective in humans due to our relatively sparse body hair, it is still an indicator of the body trying to conserve heat.

The other options do not align with the physiological responses one would expect in mild hypothermia. Fever is typically associated with hyperthermia or infection. Hypoventilation refers to reduced breathing depth or rate, which is not a characteristic sign of mild hypothermia. Lastly, sweating occurs as a mechanism to cool the body down, which is contrary to the body's goal of conserving heat during hypothermia.
