Final answer:
In a thyroid storm, which is a severe form of hyperthyroidism, a nurse should expect symptoms like restlessness due to the overactivity of the thyroid gland.
Step-by-step explanation:
A nurse caring for a client experiencing a thyroid storm should expect to see manifestations of hyperthyroidism, which is when the thyroid gland is overactive. Symptoms of hyperthyroidism include weight loss, heat intolerance, profuse sweating, and an increased heart rate. Therefore, among the options provided, the nurse should expect the client to exhibit restlessness as it is consistent with the overactivity of the thyroid gland associated with a thyroid storm. Other manifestations typically seen in thyroid storm can include tachycardia (rapid heart rate), fever, and hypertension, which align with the symptoms of hyperthyroidism like increased metabolism and heightened sympathetic nervous system activity.
