Hospital Corpsman First Class (HM1) Advancement Practice Exam 2025 - Free HM1 Practice Questions and Study Guide

In temperatures ranging from 86 to 104 degrees Fahrenheit, it is understood that energy requirements increase due to the body's need to maintain homeostasis in a warmer environment. During this temperature range, the body experiences stress that necessitates an increase in metabolic activity, generally influenced by factors such as increased heart rate, perspiration, and overall energy expenditure to cool the body down.

The correct choice indicates a 2.5-10% increase in energy requirements, which aligns with physiological studies showing that as ambient temperatures rise, the body compensates to maintain thermal equilibrium. This percentage reflects a moderate increase in caloric intake or energy expenditure necessary to cope with the physiological demands of heat, rather than a harsh or extreme increase.

It's important for healthcare providers, especially in roles such as that of a Hospital Corpsman, to understand these physiological responses when caring for patients exposed to elevated temperatures, as proper nutrition and hydration are critical in managing heat stress and preventing heat-related illnesses.
