The nurse administers a cathartic to a patient. Which finding helps the nurse determine that the cathartic has a therapeutic effect?

A) Reports decreased diarrhea.
B) Experiences pain relief.
C) Has a bowel movement.
D) Passes flatulence.

A cathartic is a laxative that stimulates a bowel movement. It would be effective if the patient experiences a bowel movement. The other options are not outcomes of administration of a cathartic. An antidiarrheal will provide relief from diarrhea. Pain medications will provide pain relief. Carminative enemas provide relief from gaseous distention (flatulence).
