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: Brudzinski’s sign is assessed by flexing the client’s neck and observing for involuntary hip and knee flexion, which indicates meningeal irritation in meningitis. It is not associated with hypocalcemia or thyroid surgery complications. B. Kernig's sign: Kernig’s sign is present when there is resistance or pain during extension of the leg while the hip is flexed, also indicating meningeal irritation. Like Brudzinski’s sign, it is unrelated to tingling or numbness in extremities or lips. C. Chvostek's sign: Chvostek’s sign is a clinical indicator of hypocalcemia and is elicited by tapping the facial nerve, leading to twitching of the facial muscles. Tingling in the hands, feet, and around the mouth is also a classic early symptom of hypocalcemia, which is a common complication after thyroid surgery due to potential parathyroid gland injury. D. Babinski's sign: Babinski’s sign refers to dorsiflexion of the big toe with fanning of the other toes upon stimulation of the sole. It suggests a neurological issue such as upper motor neuron damage and is not related to calcium imbalances or postoperative thyroid care.
