Gastrointestinal System Nursing Exam Questions

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: A

Rationale: As the nasogastric tube is passed through the oropharynx, the gag reflex is stimulated, which may cause coughing, gagging, or choking. Instead of passing through to the esophagus, the nasogastric tube may coil around itself in the oropharynx, or it may enter the larynx and obstruct the airway, pulling the tube back slightly will remove it from the larynx; advancing the tube might position it in the trachea. Swallowing closes the epiglottis over the trachea and helps move the tube into the esophagus. Slow breathing helps the client relax to reduce the gag response. The nurse should check the back of the client's throat to note if the tube has coiled. The tube may be advanced after the client relaxes.

Correct Answer: A

Rationale: Following this procedure, the nurse monitors the client's vital signs closely for indications of hemorrhage and observes the needle insertion site for bleeding and bile leakage. A sandbag is placed over the insertion site to prevent bleeding. The client is maintained on bedrest, and oral intake is avoided in the immediate postprocedure period in case surgery is necessary to control hemorrhage of bile extravasation.

Correct Answer: C

Rationale: The correct answer is C: Turnips. The nurse would instruct the client to avoid red meat, poultry, fish, turnips, horseradish, and foods such as fruits and vegetables for 3 days before and during testing. These products may alter test results. Choices A, B, and D are incorrect because they are not specifically mentioned as items to avoid before collecting a stool specimen for occult blood.

Correct Answer: A

Rationale: A lack of the intrinsic factor needed to absorb vitamin B12 occurs in pernicious anemia. Vitamin B12 is needed for the maturation of red blood cells. Vitamin B6 is not necessarily needed for pernicious anemia and can be taken orally. An antibiotic and antacids may be prescribed for certain types of gastric ulcers.
