Final answer:
In a thyroid storm, a medical emergency related to hyperthyroidism, a nurse should expect to observe hyperthermia, as this is a sign of an overactive thyroid. Bradycardia, hypotension, and constipation are more commonly associated with hypothyroidism rather than hyperthyroidism.
Step-by-step explanation:
A nurse caring for a client experiencing a thyroid storm, which is an extreme manifestation of hyperthyroidism, should expect to observe signs and symptoms consistent with an overactive thyroid. These may include hyperthermia (elevated body temperature), tachycardia (increased heart rate), hypertension, agitation, and potentially delirium or psychosis. Among the options provided, (a) bradycardia, (b) hypotension, and (d) constipation are typically associated with hypothyroidism, the opposite condition where the thyroid gland is underactive. Therefore, the expected manifestation in a thyroid storm would be (c) hyperthermia.
