A nurse in a mental health clinic is assessing a client who was recently diagnosed with anorexia nervosa. Which of the following findings should the nurse identify as an indication of laxative misuse?

A. Polyuria: Excessive urination is more commonly associated with conditions such as diabetes mellitus or diabetes insipidus, and is not a primary indicator of laxative misuse in clients with anorexia nervosa. B. Positive Trousseau's sign: A positive Trousseau's sign indicates hypocalcemia, which can result from electrolyte imbalances caused by chronic laxative misuse. Laxative overuse can lead to loss of potassium, magnesium, and calcium, increasing the risk of neuromuscular irritability and positive Trousseau's sign. C. Jaundice of the sclera: Scleral jaundice suggests liver dysfunction or hemolysis, which is not directly related to laxative misuse. While malnutrition can affect liver function, jaundice is not a specific indicator of laxative overuse. D. Hypoglycemia: Low blood glucose may occur in clients with anorexia nervosa due to inadequate nutritional intake, but it is not a direct consequence of laxative misuse. Electrolyte disturbances are more characteristic findings in laxative overuse.
