A nurse reviewing the laboratory of a client who had a total thyroidectomy discovers that his calcium level is 7 mg/dL (9-10..5 mg/dL). Which of the following client findings should the nurse expect?

A. Hypertension is not a typical manifestation of hypocalcemia and is unlikely to result from a low calcium level after thyroidectomy. B. Muscle tetany is a classic sign of hypocalcemia. After a total thyroidectomy, inadvertent removal or injury of the parathyroid glands can reduce parathyroid hormone (PTH) secretion, leading to decreased calcium levels. Tetany may present as muscle cramps, spasms, or positive Chvostek and Trousseau signs. C. Increased thirst is more commonly associated with hypernatremia or hyperglycemia, not hypocalcemia. D. Diaphoresis is usually related to sympathetic activation or conditions like hypoglycemia, not directly to low calcium levels.
