The nurse is discussing the feedback loop that regulates thyroid hormone production with a client. Which component of the feedback loop is disrupted in thyroid storm?
Hypothalamus
Pituitary gland
Thyroid gland
Parathyroid gland
The Correct Answer is B
In thyroid storm, the usual negative feedback loop between the hypothalamus, pituitary gland, and thyroid gland is disrupted. The excessive release of thyroid hormones suppresses the secretion of thyroid-stimulating hormone (TSH) from the pituitary gland, leading to uncontrolled thyroid hormone production.
