A nurse is caring for a client who is immediately postoperative following a subtotal thyroidectomy. Vital Signs 1100: Temperature 37.4° C (99.4° F) Heart rate 98/min Respiratory rate 18/min Blood pressure 128/68 mm Hg Pulse oximetry 97% on room air 1115: Temperature 37.8° C (100.1° F) Heart rate 110/min Respiratory rate 16/min Blood pressure 138/74 mm Hg Pulse oximetry 95% on room air 1130: Temperature 38.6° C (101.5° F). Heart rate 136/min Respiratory rate 16/min Blood pressure 154/86 mm Hg Pulse oximetry 95% on 2 L/min via nasal cannula Select the 4 client findings that lead the nurse to suspect that the client is experiencing thyroid storm.

A. This choice is correct because mental status changes, such as agitation, confusion, or delirium, are common signs of thyroid storm, which is a life-threatening complication of hyperthyroidism that occurs when there is excessive release of thyroid hormones. B. This choice is incorrect because wound drainage is not a specific sign of thyroid storm, but rather a potential complication of any surgery that can indicate infection or bleeding. C. This choice is correct because tachycardia, or increased heart rate, is a common sign of thyroid storm, which can result from increased metabolic demand and increased sensitivity to catecholamines. D. This choice is incorrect because pain is not a specific sign of thyroid storm, but rather a common symptom of any surgery that can be managed with analgesics. E. This choice is correct because hypertension, or increased blood pressure, is a common sign of thyroid storm, which can result from increased cardiac output and peripheral vascular resistance. F. This choice is correct because hyperthermia, or increased temperature, is a common sign of thyroid storm, which can result from increased heat production and impaired heat dissipation.
