The nurse is educating a client about the triggers for thyroid storm. Which statement accurately describes a common trigger for thyroid storm?
"Thyroid storm is triggered by prolonged exposure to cold temperatures."
"Thyroid storm is commonly triggered by excessive iodine intake."
"Thyroid storm is triggered by an overproduction of parathyroid hormone."
"Thyroid storm is commonly triggered by bacterial infections."
The Correct Answer is B
Excessive iodine intake, such as from contrast agents used in imaging studies, can trigger thyroid storm in individuals with underlying hyperthyroidism. The additional iodine can stimulate further thyroid hormone release and exacerbate the condition.
Incorrect choices:
a. Prolonged exposure to cold temperatures is not a common trigger for thyroid storm.
c. Parathyroid hormone is not directly involved in thyroid hormone regulation and does not trigger thyroid storm.
d. Bacterial infections are not a common trigger for thyroid storm.

Incorrect choices:
a. Levothyroxine (Synthroid) is a thyroid hormone replacement medication and is contraindicated in the treatment of thyroid storm, as it would worsen the hyperthyroid state.
c. Propranolol (Inderal) is a beta-blocker that can help control symptoms such as tachycardia and hypertension in thyroid storm, but it does not address the underlying thyroid hormone excess.
d. Liothyronine (Cytomel) is a thyroid hormone replacement medication and is contraindicated in the treatment of thyroid storm, as it would worsen the hyperthyroid state.
