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

Choice A rationale Lanugo, the growth of fine, downy body hair, is a common finding in individuals with anorexia nervosa. This physiological response is a compensatory mechanism to conserve body heat due to significant loss of subcutaneous fat and hypothermia resulting from prolonged caloric restriction and malnutrition. Choice B rationale Hyperkalemia, an elevated potassium level (normal range 3.5-5.0 mEq/L), is generally not expected in anorexia nervosa. More commonly, hypokalemia can occur due to purging behaviors like vomiting or laxative abuse, leading to significant electrolyte imbalances. Hyperkalemia would be an atypical finding. Choice C rationale Hyperglycemia, elevated blood glucose levels (normal fasting 70-99 mg/dL), is not a typical finding in anorexia nervosa. Due to chronic caloric restriction and depleted glycogen stores, individuals with anorexia nervosa are more prone to hypoglycemia or euglycemia rather than elevated blood sugar. Choice D rationale Swollen parotid glands, often referred to as sialadenosis, are more commonly associated with bulimia nervosa due to repeated vomiting. The frequent emesis causes hypertrophy of the salivary glands. While not exclusive to bulimia, it is less characteristic of anorexia nervosa without purging behaviors.
