Question

Quizplus · Accepted Answer

Rationale 1: A hypophysectomy removes the anterior pituitary. Hormones normally produced by this portion of the pituitary are lacking. TSH is absent, so the thyroid gland does not receive messages to make thyroid hormone, and a life-long supplement is needed.
Rationale 2: This statement does not explain the role of the pituitary gland in thyroid regulation.
Rationale 3: The client's TSH level is not too high from surgery.
Rationale 4: The thyroid is in the neck, and the pituitary gland is in the cranium.
