The nurse is assessing a client post-thyroidectomy. Which finding is most concerning and requires immediate intervention?

✓ Correct Answer: Option D

A positive Trousseau's sign indicates hypocalcemia, a potential complication of thyroidectomy due to accidental removal or damage to the parathyroid glands. Hypocalcemia can lead to laryngeal spasm, tetany, and seizures, requiring immediate calcium replacement.
