Gastrointestinal System Nursing Exam Questions
1. 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.
2. A client with liver dysfunction has low serum levels of thrombin. The nurse provides care, anticipating that this client is most at risk of
- A. Dehydration
- B. Malnutrition
- C. Bleeding
- D. Infection
Correct answer: C
Rationale: Thrombin is produced by the liver and is necessary for normal clotting. When a client with liver dysfunction has low serum levels of thrombin, they are at risk of bleeding due to impaired clotting mechanisms. Dehydration (choice A) is not directly related to low thrombin levels. Malnutrition (choice B) may impact overall health but is not the most immediate concern associated with low thrombin levels. Infection (choice D) is not directly related to the clotting function affected by low thrombin levels.
3. Which of the following factors is believed to cause ulcerative colitis?
- A. Acidic diet
- B. Altered immunity
- C. Chronic constipation
- D. Emotional stress
Correct answer: B
Rationale: Ulcerative colitis is believed to be caused by an altered immune response in the gastrointestinal tract.
4. Mucosal barrier fortifiers are used in peptic ulcer disease management for which of the following indications?
- A. To inhibit mucus production
- B. To neutralize acid production
- C. To stimulate mucus production
- D. To stimulate hydrogen ion diffusion back into the mucosa
Correct answer: C
Rationale: Mucosal barrier fortifiers stimulate mucus production, which helps protect the lining of the stomach and manage peptic ulcer disease.
5. A female client complains of gnawing epigastric pain for a few hours after meals. At times, when the pain is severe, vomiting occurs. Specific tests are indicated to rule out:
- A. Cancer of the stomach
- B. Peptic ulcer disease
- C. Chronic gastritis
- D. Pylorospasm
Correct answer: A
Rationale: Specific tests are indicated to rule out cancer of the stomach when a client complains of gnawing epigastric pain and vomiting after meals.
