Gastrointestinal System Nursing Exam Questions

Correct Answer: C

Rationale: The client with a mild case of ulcerative colitis is often advised to follow a diet low in roughage and avoid milk. This dietary approach helps reduce the frequency of diarrhea in these clients. Therefore, the correct therapeutic diet for the client with ulcerative colitis in this scenario is a low-roughage diet without milk. Choices A, B, and D are incorrect because high-fat, high-protein, and low-roughage with milk diets are not typically recommended for clients with ulcerative colitis, especially those with mild cases.

Correct Answer: C

Rationale: A sign indicating that a client's colostomy is open and ready to function is passage of feces and flatus. When this occurs, gastric suction is ordinarily discontinued, and the client is allowed to start taking fluids and food orally. Absence of bowel sounds would indicate that the tube should remain in place because peristalsis has not yet returned. Absence of nausea and vomiting is not a criterion for judging whether or not gastric suction should be continued. Passage of mucus from the rectum will not occur in this client because the rectum is removed in this surgery. Absence of stomach drainage is not a criterion for judging whether or not gastric suction should be continued.

Correct Answer: B

Rationale: To prevent reflux of stomach acid into the esophagus, the nurse should advise the client to avoid foods and beverages that tend to increase stomach acid, such as coffee and alcohol. The nurse also should teach the client to avoid lying down after meals, which can aggravate reflux, and to take antacids after eating. The client doesn't need to limit fluids with meals as long as the fluids aren't gastric irritants.

Correct Answer: B

Rationale: Intrinsic factor is produced in the stomach but is used to aid in the absorption of vitamin B12 in the small intestine. Vitamin B12 is not absorbed in the large intestine (options 3 and 4).

Correct Answer: B

Rationale: Lactulose is prescribed for the client with hepatic encephalopathy to reduce bacterial breakdown of protein in the bowel. The medication creates an acidic environment in the bowel and causes the ammonia to leave the bloodstream and enter the colon. Ammonia then becomes trapped in the bowel. Lactulose also has a laxative effect that allows for the elimination of the ammonia.
