Gastrointestinal System Nursing Exam Questions

Correct Answer: B

Rationale: After checking the residual feeding contents, the gastric contents are reinstalled into the stomach by removing the syringe bulb or plunger and pouring the gastric contents into the syringe and through the nasogastric tube. Gastric contents should be reinstalled to maintain the client's electrolyte balance. The gastric contents should be poured into the nasogastric tube through a syringe without a plunger and not injected by putting pressure on the plunger. Gastric contents do not need to be mixed with water or should the contents be discarded.

Correct Answer: B

Rationale: The pain that is associated with acute pancreatitis is often severe and is located in the epigastric region and radiates to the back. Options 1, 3, and 4 are incorrect because they are not specific for the pain experienced by the client with pancreatitis.

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: 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: 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.
