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?

Rationale: A. Kernig's sign: This is associated with meningeal irritation in meningitis, not postoperative thyroidectomy complications. It involves pain or resistance when extending the knee while the hip is flexed. B. Brudzinski's sign: Also linked to meningitis, this sign is positive when passive neck flexion causes hip and knee flexion. It does not relate to hypocalcemia after thyroid surgery. C. Babinski's sign: This neurological reflex indicates corticospinal tract dysfunction, such as in upper motor neuron lesions. It is unrelated to calcium imbalance following thyroidectomy. D. Chvostek's sign: Tingling around the mouth, hands, and feet suggests hypocalcemia, a risk after thyroidectomy due to parathyroid injury. Chvostek’s sign (facial muscle twitching when tapping the facial nerve) helps confirm neuromuscular irritability from low calcium levels.
