Gastrointestinal System Nursing Exam Questions

Correct Answer: C

Rationale: Although no special diet is required to treat viral hepatitis, it is generally recommended that clients consume a diet with low-fat content because fat may be tolerated poorly due to decreased bile production. Small, frequent meals are preferable and may prevent nausea. Appetite is often better in the morning, so it is easier to eat a good breakfast. An adequate fluid intake of 2500 to 3000 mL per day that includes nutritional juices is also important.

Correct Answer: B

Rationale: Antibiotics are administered preoperatively to reduce the bacterial count in the colon. The client will be placed on a low residue diet to help cleanse the bowel before surgery but typically is not placed on NPO status until 8 to 12 hours before surgery. Laxatives and enemas may also be administered. Chest tubes would not be expected postoperatively. There is no need to limit the client's activity before surgery.

Correct Answer: C

Rationale: The lower esophageal sphincter is a functional sphincter that normally remains closed except when food or fluids are swallowed. If relaxation of this sphincter occurs, the client could experience symptoms of gastroesophageal reflux disease.

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: It is important for the client to have frequent rest periods. Repeated episodes of diarrhea interrupt sleep patterns, and poor nutrition may also cause the client to feel weak. If the client is experiencing a severe exacerbation of ulcerative colitis, bed rest may be ordered. Antidiarrheal medications can be used selectively in ulcerative colitis but are not recommended for regular use as they can lead to colonic dilation. The client should maintain a low-residue, high-calorie, caffeine-free diet.
