The nurse is educating a client about medications used in the management of thyroid storm. Which medication should the nurse explain is used to temporarily reduce thyroid hormone release and manage severe hyperthyroidism?
Levothyroxine (Synthroid)
Methimazole (Tapazole)
Propranolol (Inderal)
Sodium polystyrene sulfonate (Kayexalate)
The Correct Answer is D
Sodium polystyrene sulfonate (Kayexalate) is used to bind excess thyroid hormones and temporarily reduce their release. It is part of the medical management of thyroid storm to manage severe hyperthyroidism.
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.

Explanation
After radioactive iodine therapy, it may take several weeks for thyroid hormone levels to normalize. Continuing antithyroid medication during this period helps prevent exacerbation of hyperthyroidism and potential thyroid storm.
Incorrect choices:
a. This choice is incorrect. While avoiding excessive iodine intake is important, avoiding all foods high in iodine is unnecessary and could lead to nutritional deficiencies.
b. This choice is incorrect. Strenuous physical activity can exacerbate hyperthyroidism and increase the risk of thyroid storm. Moderation in physical activity is recommended.
c. This choice is incorrect. Stopping antithyroid medication after radioactive iodine therapy is not recommended, as thyroid hormone levels may not immediately normalize.
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.
