Answer to Question 1

A
Feedback:
Nitazoxanide (Alinia) is an antiprotozoal agent used specifically for treating diarrhea resulting from infection with Giardia lamblia or Cryptosporidium parvum. It is not used in the treatment of diarrhea associated with E. coli, Salmonella, or Campylobacter jejuni.

Answer to Question 2

A
Feedback:
Spironolactone promotes retention of sodium and water and excretion of potassium by stimulating the sodiumpotassium exchange mechanism in the distal tubule. The patient will not have greater potassium losses, water losses, or sodium losses with spironolactone rather than furosemide.
