Question 6

A surgical individual just arrived on the unit from the postanesthesia care unit.This person's respirations are four per minute and shallow.As the nurse calls for assistance, the person suddenly feels jittery, and breathing quickens.Which of the following feedback loops is operating for the nurse in this situation?

Accepted Answer

A) The central nervous system stimulates hypothalamus-releasing factor, which acts on the anterior pituitary gland to secrete thyroid-stimulating hormone (TSH) and stimulates the release of thyroxine (T4) and triiodothyronine (T3). 
B) The central nervous system directly stimulates the release of insulin, which reduces blood glucose levels. 
C) The central nervous system directly stimulates the adrenal medulla to secrete epinephrine and stimulates hypothalamus-releasing factor, which acts on the anterior pituitary gland to secrete adrenocorticotropic-stimulating hormone (ACTH), stimulating the release of cortisol. 
D) The central nervous system stimulates the hypothalamus to synthesize oxytocin and antidiuretic hormone, which are secreted by the posterior pituitary, activating uterine contraction and renal absorption of water. 
A) The central nervous system stimulates hypothalamus-releasing factor, which acts on the anterior pituitary gland to secrete thyroid-stimulating hormone (TSH) and stimulates the release of thyroxine (T4) and triiodothyronine (T3). 
B) The central nervous system directly stimulates the release of insulin, which reduces blood glucose levels. 
C) The central nervous system directly stimulates the adrenal medulla to secrete epinephrine and stimulates hypothalamus-releasing factor, which acts on the anterior pituitary gland to secrete adrenocorticotropic-stimulating hormone (ACTH), stimulating the release of cortisol. 
D) The central nervous system stimulates the hypothalamus to synthesize oxytocin and antidiuretic hormone, which are secreted by the posterior pituitary, activating uterine contraction and renal absorption of water.

A) Increased triiodothyronine (T3) 
B) Increased thyroxine (T4) 
C) Increased thyroid-stimulating hormone (TSH)
