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.

Correct Answer is C
Explanation
Thyroid storm is associated with sympathetic nervous system stimulation, leading to increased release of thyroid hormones from the thyroid gland. This results in a cascade of hypermetabolic effects throughout the body.
Correct Answer is A
Explanation
Administering antithyroid medications, such as propylthiouracil (PTU) or methimazole, is a priority in managing thyroid storm. These medications inhibit the production of thyroid hormones and help control the hyperthyroid state.
Incorrect choices:
b. Initiating high-dose thyroid hormone replacement therapy is not appropriate for thyroid storm, as the goal is to reduce thyroid hormone levels, not increase them.
c. While intravenous fluid resuscitation may be necessary to manage dehydration and electrolyte imbalances associated with thyroid storm, it is not the initial priority intervention.
d. Encouraging physical activity is contraindicated in thyroid storm, as it can exacerbate symptoms and increase the risk of complications.
