Gastrointestinal System Nursing Exam Questions
1. The nurse assesses the client's understanding of the relationship between body position and gastroesophageal reflux. Which response would indicate that the client understands measures to avoid problems with reflux while sleeping?
- A. I can elevate the foot of the bed 4 to 6 inches.
- B. I can sleep on my stomach with my head turned to the left.
- C. I can sleep on my back without a pillow under my head.
- D. I can elevate the head of the bed 4 to 6 inches.
Correct answer: D
Rationale: Sleeping with the head of the bed elevated encourages movement of food through the esophagus by gravity. By fostering esophageal acid clearance, gravity helps keep the acidic pepsin and alkaline biliary secretions from contacting the esophagus. Elevating the foot of the bed does not affect clearance of esophageal acid. Sleeping on the stomach with the head turned to the left will not decrease reflux incidence. Sleeping flat without a pillow under the head does not enhance clearance.
2. A client is admitted to the hospital after vomiting bright red blood and is diagnosed with a bleeding duodenal ulcer. The client develops a sudden, sharp pain in the midepigastric area along with a rigid, boardlike abdomen. These clinical manifestations most likely indicate which of the following?
- A. An intestinal obstruction has developed
- B. Additional ulcers have developed
- C. The esophagus has become inflamed
- D. The ulcer has perforated
Correct answer: D
Rationale: A sudden, sharp pain in the midepigastric area along with a rigid, boardlike abdomen indicates that the ulcer has perforated.
3. The nurse is planning to teach the client with gastroesophageal reflux disease about substances that will increase the lower esophageal sphincter pressure. Which of the following items would the nurse include on this list?
- A. Fatty foods
- B. Nonfat milk
- C. Chocolate
- D. Coffee
Correct answer: B
Rationale: Foods that increase the lower esophageal sphincter (LES) pressure will decrease reflux, and lessen the symptoms of gastroesophageal reflux disease (GERD). The food substance that will increase the LES pressure is nonfat milk. The other substances listed decrease the LES pressure, thus increasing reflux symptoms. Aggravating substances include chocolate, coffee, fatty foods and alcohol.
4. A home care nurse is visiting a client with a diagnosis of pernicious anemia that developed as a result of gastric surgery. The nurse instructs the client that because the stomach lining produces a decreased amount of intrinsic factor in this disorder, the client will need
- A. Vitamin B12 injections.
- B. Vitamin B6 injections.
- C. An antibiotic.
- D. An antacid.
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.
5. Which of the following mechanisms can facilitate the development of diverticulosis into diverticulitis?
- A. Treating constipation with chronic laxative use, leading to dependence on laxatives
- B. Chronic constipation causing an obstruction, reducing forward flow of intestinal contents
- C. Herniation of the intestinal mucosa, rupturing the wall of the intestine
- D. Undigested food blocking the diverticulum, predisposing the area to bacterial invasion
Correct answer: D
Rationale: The correct answer is D. Undigested food blocking the diverticulum can lead to bacterial invasion, causing inflammation and turning diverticulosis into diverticulitis. Choices A, B, and C do not directly facilitate the development of diverticulitis. Choice A involves a different mechanism related to laxative use, choice B describes a complication of chronic constipation but does not necessarily lead to diverticulitis, and choice C refers to a different condition involving herniation of the intestinal mucosa.
