Gastrointestinal System Nursing Exam Questions

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: 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: When the nurse removes a nasogastric tube, the client is instructed to take and hold a deep breath. This will be obstructed temporarily during the tube removal. This allows for easy withdrawal through the esophagus into the nose. The nurse removes the tube with one smooth, continuous pull.

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: C

Rationale: Nasogastric tubes are discontinued when normal function returns to the gastrointestinal tract. The tube will be removed before gastrointestinal healing. Food would not be administered unless bowel function returns. Although the physician determines when the nasogastric tube will be removed, option 4 does not determine effectiveness of teaching.
