Answer to Question 1

B
Feedback:
The hypothalamus gland is called the master gland of the neuroendocrine system because it regulates both nervous and endocrine responses to internal and external stimuli. There is more to the hypothalamus than just its stimulation of the pituitary gland or its production of releasing hormones that leads it to be considered the master gland. The neuroendocrine system combines the nervous and endocrine systems to work closely together to maintain regulatory control and homeostasis in the body.

Answer to Question 2

C
Feedback:
Serum digoxin levels will be very high and unreliable for about 3 days after the digoxin immune Fab infusion because of the high levels of digoxin in the blood. The patient should not be redigitalized for several days to 1 week after digoxin immune Fab has been used, because of the potential of fragments remaining in the blood. There is no need to notify the health care provider or to administer digoxin immune Fab again.
