Gastrointestinal System Nursing Exam Questions

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.

Correct Answer: B

Rationale: The correct intervention for a client with acute pancreatitis is to prescribe pain medications such as meperidine to manage the abdominal pain, which is a prominent symptom of the condition. The other options are incorrect because: A) Clients with acute pancreatitis are normally placed on NPO (nothing by mouth) status to rest the pancreas, so small, frequent high-calorie feedings are not indicated. C) Placing the client in a side-lying position with the head elevated 45-degrees helps decrease tension on the abdomen and may ease pain, but it is not a standard intervention for acute pancreatitis. D) Administering antacids and anticholinergics to suppress gastrointestinal secretions is not a routine intervention for acute pancreatitis.

Correct Answer: C

Rationale: Emotional support from the family is the main need. A special diet doesn't focus on emotional needs. Role expectations don't address the main issue, but emotional support while the client is fulfilling these roles is important. The family's ability to understand the ups and downs of the illness will help them but not the client.

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: Serosanguineous drainage with a small amount of bile is expected from the Penrose drain for the first 24 hours. Drainage then decreases, and the drain is removed usually within 48 hours. The nurse does not need to notify the physician. A sterile dressing covers the site and should be changed to prevent infection and skin excoriation.
