1. The nurse is caring for a client with chronic gastritis. The nurse monitors the client, knowing that this client is at risk for which of the following vitamin deficiencies?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin C
- D. Vitamin E
Correct answer: B
Rationale: Clients with chronic gastritis are at risk for Vitamin B12 deficiency due to impaired absorption.
2. Which of the following dietary measures would be useful in preventing esophageal reflux?
- A. Eating small, frequent meals
- B. Increasing fluid intake
- C. Avoiding air swallowing with meals
- D. Adding a bedtime snack to the dietary plan
Correct answer: A
Rationale: Eating small, frequent meals helps prevent esophageal reflux.
3. The nurse is scheduling diagnostic tests for a client. If all of the following diagnostic tests are ordered, which would be performed last?
- A. Gallbladder series
- B. Barium enema
- C. Barium swallow
- D. Oral cholecystogram
Correct answer: C
Rationale: The correct answer is C, 'Barium swallow.' A barium swallow should be done after a barium enema or gallbladder series to prevent the contrast used in the barium swallow from obstructing the view of other organs. It takes several days for swallowed barium to pass completely out of the gastrointestinal tract. Choices A, B, and D are incorrect because a barium swallow should be the last test performed to ensure clear imaging without interference from residual contrast material.

- A. To inhibit mucus production
- B. To neutralize acid 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.

- B. Monitor IV fluids for the shift
- C. Regularly assess respiratory status
- D. Check that the balloon is deflated on a regular basis
