Gastrointestinal Medications NCLEX Prep II
The nurse is administering senna to an older client. What is the expected result of this
medication?
1. It increases peristalsis.
2. It lines the wall of the bowel.
3. It adds fiber and bulk to the stool.
4. It stimulates the vagus nerve to improve bowel tone.
Rationale: Senna works by altering the transport of water and electrolytes in the large
intestine, which causes accumulation of water in the mass of stool and increased
peristalsis. The other options are incorrect actions for this medication.
The nurse has given instructions to a client who has just been prescribed
cholestyramine. Which statement by the client indicates a need for further
instruction?
1."I will continue taking vitamin supplements."
2."This medication will help to lower my cholesterol."
3."This medication should only be taken with water."
4."A high-fiber diet is important while taking this medication."
Rationale: Cholestyramine is a bile acid sequestrant used to lower the cholesterol level,
and client compliance is a problem because of its taste and palatability. The use of
flavored products or fruit juices can improve the taste. Some side effects of bile acid
sequestrants include constipation and decreased vitamin absorption.

3.Right after meals and at bedtime
4.30 minutes before meals and at bedtime
Rationale: Metoclopramide is a gastrointestinal stimulant. Administration should be
scheduled 30 minutes before meals and at bedtime to allow the medication time to
begin working before food intake and digestion. The other options are incorrect.
