Answer to Question 1

A
Feedback:
The HPA functions through negative feedback loops or the direct use of inhibiting factors to constantly keep particular hormones regulated. Other options are incorrect because hormones are not regulated by feedback loops, releasing factors, or stimulating factors.

Answer to Question 2

D
Feedback:

0.25 mg/1 tablet = 0.125 mg dose/X. Cross-multiply to determine 0.5 or 1/2 of a tablet is to be taken daily. The nurse may request the pharmacy dispense a different concentration to prevent the patient from having to cut the tablet in half.
