A nurse is collecting data from a client who has a calcium level of 12 mg/dL (9-10.5 mg/dL). Which of the following manifestations should the nurse expect?

A. Increased appetite is not associated with hypercalcemia; in fact, hypercalcemia can cause anorexia or nausea. B. Decreased deep tendon reflexes are a common neuromuscular manifestation of hypercalcemia. Elevated calcium levels reduce neuromuscular excitability, leading to muscle weakness, lethargy, and hypoactive reflexes. C. Diarrhea is more commonly associated with hypocalcemia or other gastrointestinal irritants. Hypercalcemia often causes constipation rather than diarrhea. D. Hypotension is not typical in hypercalcemia; instead, hypertension may occur due to increased vascular tone and fluid shifts.
