A nurse is caring for a client who is 1 day postoperative following a subtotal thyroidectomy. The client reports a tingling sensation in the hands, the soles of the feet, and around the lips. For which of the following findings should the nurse assess the client?

A. Brudzinski's sign is incorrect because it is associated with meningeal irritation, not postoperative thyroidectomy complications. B. Babinski's sign is incorrect because it is a neurologic reflex finding and not related to hypocalcemia. C. Chvostek's sign is correct because tingling around the mouth, hands, and feet after thyroidectomy suggests hypocalcemia due to possible parathyroid gland injury; Chvostek’s sign is a clinical indicator of hypocalcemia. D. Kernig's sign is incorrect because it is also associated with meningeal irritation, not calcium imbalance.
