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.

Incorrect choices:
a. Levothyroxine (Synthroid) is a thyroid hormone replacement medication used to treat hypothyroidism and would exacerbate thyroid storm if given.
b. Methimazole (Tapazole) is an antithyroid medication that inhibits thyroid hormone synthesis and is used to manage thyroid storm, but it does not temporarily reduce thyroid hormone release.
c. Propranolol (Inderal) is a beta-blocker used to manage symptoms of hyperthyroidism but does not directly reduce thyroid hormone release.
