Which physical problem related to anorexia nervosa would the nurse be most likely to find during an assessment?

A. Hyperkalemia: In anorexia nervosa, hypokalemia is much more common due to vomiting, diuretic use, or laxative abuse. Elevated potassium levels are not typically associated with this disorder. B. Oversensitivity to heat: Clients with anorexia nervosa often have difficulty maintaining body temperature because of severe weight loss and lack of insulating body fat. They usually develop cold intolerance rather than heat oversensitivity. C. Tachycardia: Malnutrition generally slows metabolic processes, leading to bradycardia rather than tachycardia. A low resting heart rate is a classic cardiovascular finding in anorexia nervosa. D. Lanugo: Fine, soft body hair (lanugo) develops as a compensatory mechanism to help the body conserve heat in the absence of sufficient fat stores. This is one of the hallmark physical findings in patients with anorexia nervosa.
