The nurse is explaining the pathophysiology of thyroid storm to a client. Which statement accurately describes the underlying process that contributes to thyroid storm?
"Thyroid storm occurs due to an underproduction of thyroid hormones."
"Thyroid storm is triggered by an overactive parathyroid gland."
"Thyroid storm results from an excessive release of thyroid hormones into the bloodstream."
"Thyroid storm is caused by inflammation of the thyroid gland."
The Correct Answer is C
Thyroid storm is a life-threatening condition characterized by a sudden and severe increase in thyroid hormone levels in the bloodstream. This occurs due to the uncontrolled release of thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), from the thyroid gland.

Correct Answer is D
Explanation
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
Propranolol is a beta-blocker that helps manage the cardiovascular symptoms of thyroid storm, such as tachycardia and hypertension. It is often administered as a priority to stabilize the client's condition.
Incorrect choices:
a. This choice is incorrect. Levothyroxine is a thyroid hormone replacement medication and would not be administered as a priority in the acute management of thyroid storm.
b. This choice is incorrect. Methimazole is an antithyroid medication used to block thyroid hormone production. It is important for long-term management but may not be administered as a priority during a thyroid storm crisis.
d. This choice is incorrect. Calcium gluconate may be administered to address the potential risk of hypocalcemia associated with thyroid storm, but it is not typically administered as a first-line priority medication.
