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 D
Explanation
The thyroid peroxidase antibody (TPOAb) test is used to detect the presence of antibodies against thyroid peroxidase, an enzyme involved in thyroid hormone production. Elevated TPOAb levels indicate autoimmune thyroid conditions, which can contribute to thyroid storm.
Correct Answer is C
Explanation
Thyroid storm is a life-threatening condition characterized by severe hyperthyroidism. Hypertension is a common manifestation of thyroid storm, along with tachycardia, fever, and other signs of sympathetic nervous system overactivity.
Incorrect choices:
a. This choice is incorrect. Bradycardia is not a typical finding in thyroid storm. Tachycardia is more common due to increased sympathetic activity.
b. This choice is incorrect. Thyroid storm is associated with hyperthermia, not hypothermia.
d. This choice is incorrect. Weight loss, rather than weight gain, is a characteristic feature of hyperthyroidism, including thyroid storm.
