Which assessment finding of a patient 8 hours after a subtotal thyroidectomy does the nurse consider most relevant as an indication of a possible complication?

Choice A reason: Moderate serosanguineous drainage is expected in the early postoperative period and does not necessarily indicate a complication unless it becomes excessive or changes in character. It should be monitored but is not the most concerning finding. Choice B reason: A slight drop in respiratory rate may be due to sedation or pain medication and is not immediately alarming unless accompanied by other signs of respiratory compromise. It requires monitoring but is not the most critical sign of a complication. Choice C reason: Hand spasms during blood pressure measurement suggest a positive Trousseau’s sign, which is indicative of hypocalcemia. This is a serious complication following thyroidectomy due to possible inadvertent removal or damage to the parathyroid glands, which regulate calcium levels. Hypocalcemia can lead to tetany and seizures if untreated. Choice D reason: Responding to questions but not opening eyes may indicate fatigue or sedation, but it is not a specific sign of a surgical complication. It should be assessed in context but is not the most relevant finding.
