The client is diagnosed with irritable bowel syndrome (IBS). Which intervention should the nurse teach the client to reduce symptoms?
- A. Instruct the client to avoid drinking fluids with meals.
- B. Explain the need to decrease intake of flatus-forming foods.
- C. Teach the client how to perform gentle perianal care.
- D. Encourage the client to attend a support group meeting.

- A. A decrease in alcohol intake.
- B. Maintaining a bland diet.
- C. A return to previous activities.
- D. A decrease in gastric distress.
