Answer to Question 1

D
Feedback:
Mesna combines with a urotoxic metabolite of ifosfamide to reduce the damaging effects of ifosfamide. It has no effect on urine output, does not provide a shield for the kidney, and has no impact on white blood cell production.

Answer to Question 2

A
Feedback:
Anticholinergic drugs decrease sweating. As a result, the body is not as effective at reducing internal temperature as this could result in fever and heatstroke. Elderly people taking anticholinergic drugs do not need to avoid fluids high in potassium, foods high in vitamin K, or anything containing red dye.
