554. Answer: 2

Rationale: The principal manifestations of Crohn’s disease are diarrhea and
abdominal pain. Infliximab is an immunomodulator that reduces the degree of
inflammation in the colon, thereby reducing the diarrhea. Options 1, 3, and 4 are
unrelated to this medication.
Test-Taking Strategy: Focus on the subject, treatment for Crohn’s disease, and
note the strategic word, effectiveness. Eliminate option 4, because gastric bleeding is
not a characteristic of Crohn’s disease. Monitoring the leukocyte count and liver
enzyme levels is appropriate when infliximab is given but not to evaluate the
effectiveness of treatment, eliminating options 1 and 3.

555. Answer: 3

Rationale: Loperamide is an antidiarrheal agent. It is used to manage acute and
chronic diarrhea in conditions such as inflammatory bowel disease. Loperamide also
can be used to reduce the volume of drainage from an ileostomy. It is not used for
the conditions in options 1, 2, and 4.
Test-Taking Strategy: Focus on the subject, the action of loperamide. Recalling
that this medication is an antidiarrheal agent will direct you to the correct option.
