Answer to Question 1

A
Feedback:
Pain comes from the activation of pain fibers by histamine and the kinin system, occurring any time a cell is injured. Histamine also causes vasodilation, increases capillary permeability, and facilitates phagocytosis.

Answer to Question 2

C
Feedback:
Peripheral edema is an identified adverse effect of leuprolide therapy. Constipation not diarrhea; urinary frequency not urinary retention; and anorexia not increased appetite are also identified adverse effects.
