Final answer:
The correct answer is c. Temperature 35.8° C (96.4° F) which indicates hypothermia and requires immediate hospitalization, as this is a serious complication of anorexia nervosa.
Step-by-step explanation:
A student asked which of the following findings in a client with anorexia nervosa indicates a need for hospitalization: a. Total body fat 8.7%, b. Potassium 3.6 mEq/L, c. Temperature 35.8° C (96.4° F), or d. Heart rate 54/min. The correct answer is c. Temperature 35.8° C (96.4° F). A body temperature lower than 36.1° C (97° F) can indicate hypothermia and is a critical condition that would require immediate hospitalization to address potential complications like cardiac arrest, respiratory issues, or systemic infections which are serious risks associated with anorexia nervosa.
