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

Rationale: A. Diarrhea is more common with low calcium (hypocalcemia), while hypercalcemia often causes constipation. B. Hypercalcemia usually causes hypertension due to increased vascular tone, not hypotension. C. Elevated calcium levels can depress neuromuscular activity, leading to decreased deep tendon reflexes. D. Increased appetite is not associated with hypercalcemia; hypercalcemia may cause nausea and decreased appetite.
