Correct Answer: A

Rationale: Profuse vomiting is the classic sign of small bowel obstruction and rarely occurs with large bowel obstruction. Abdominal discomfort and distention are present in both small and large bowel obstructions, but distention is more common in large bowel obstruction. High-pitched bowel sounds indicate hyperperistalsis, which occurs early in obstruction.

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: A

Rationale: In a Billroth II procedure the proximal remnant of the stomach is anastomosed to the proximal jejunum. Patency of the nasogastric tube is critical for preventing the retention of gastric secretions. The nurse should never irrigate or reposition the gastric tube after gastric surgery, unless specifically ordered by the physician. In this situation the nurse should clarify the order. Coughing and deep breathing exercises, leg exercises, and early ambulation are appropriate postoperative interventions.

Correct Answer: B

Rationale: Cholestyramine resin binds with bile salts in the intestines to form a compound that is excreted in the feces. The client should be instructed to mix the medication with 3 to 6 oz of water, milk, fruit juice, or soup. The medication should be administered before meals. The medication is not administered via rectal suppository.

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.
