The nurse is educating a client about diagnostic evaluations for thyroid storm. Which diagnostic test involves administering a radioactive tracer and measuring its uptake by the thyroid gland?
Thyroid ultrasound
Radioactive iodine uptake test
Thyroid-stimulating hormone (TSH) level
Thyroid peroxidase antibody (TPOAb) test
The Correct Answer is B
The radioactive iodine uptake test involves administering a small amount of radioactive iodine and measuring its uptake by the thyroid gland. This test assesses the thyroid's ability to take up iodine and produce thyroid hormones.
Incorrect choices:
a. Thyroid ultrasound is used to visualize the thyroid gland's structure and function but does not involve the use of radioactive tracers.
c. Thyroid-stimulating hormone (TSH) level is a blood test that measures the pituitary gland's response to thyroid hormone levels.
d. Thyroid peroxidase antibody (TPOAb) test detects the presence of thyroid autoantibodies and is used to diagnose autoimmune thyroid conditions.

Correct Answer is C
Explanation
Tremors, restlessness, and anxiety are early signs of thyroid storm. Thyroid storm is a life-threatening condition characterized by an excessive release of thyroid hormones, leading to hypermetabolic state.
Incorrect choices:
a. This choice is incorrect. Bradycardia is not typically associated with thyroid storm. Tachycardia is more common due to increased sympathetic activity.
b. This choice is incorrect. Thyroid storm is associated with hyperthermia, not hypothermia. Increased metabolic rate leads to elevated body temperature.
d. This choice is incorrect. Decreased appetite is not a priority assessment finding in thyroid storm. More significant symptoms such as agitation and tachycardia take precedence.
Correct Answer is D
Explanation
Excessive thyroid hormone levels in thyroid storm lead to hypermetabolism, which results in increased oxygen consumption, heat production, and energy expenditure. This hypermetabolic state is associated with symptoms such as tachycardia, hypertension, fever, and profuse sweating.
