A nurse is caring for a client who has anorexia nervosa. Which of the following findings should the nurse expect?

A. Hypokalemia, not hyperkalemia, is more common in clients with anorexia nervosa, especially if they engage in vomiting, laxative use, or diuretic misuse. Electrolyte imbalances in anorexia are typically related to malnutrition and fluid loss. B. Hypoglycemia is more likely in anorexia nervosa due to prolonged inadequate caloric intake. Hyperglycemia is not an expected finding unless there is an underlying endocrine disorder. C. Swollen parotid glands are commonly associated with bulimia nervosa, not anorexia nervosa. Recurrent vomiting in bulimia leads to parotid enlargement and “chipmunk cheeks,” which are not characteristic of anorexia. D. Lanugo is fine, soft hair that develops on the body of clients with anorexia nervosa. It appears as a compensatory mechanism to help conserve body heat due to the severe loss of subcutaneous fat. Lanugo is a classic physical sign of chronic malnutrition and is commonly observed on the back, arms, and face.
