1. Which of the following definitions best describes gastritis?

Correct answer: C

Rationale: The correct answer is C: 'Inflammation of the gastric mucosa.' Gastritis is characterized by inflammation of the stomach lining, specifically the gastric mucosa. This inflammation can be caused by various factors such as infections, medications, alcohol, or autoimmune diseases. Choice A, 'Erosion of the gastric mucosa,' is incorrect because erosion refers to the wearing away of tissue rather than inflammation. Choice B, 'Inflammation of a diverticulum,' is incorrect because gastritis specifically involves inflammation of the stomach lining, not a diverticulum. Choice D, 'Reflux of stomach acid into the esophagus,' describes gastroesophageal reflux disease (GERD), which is different from gastritis.

2. Which of the following tasks should be included in the immediate postoperative management of a client who has undergone gastric resection?

Correct answer: D

Rationale: Monitoring for symptoms of hemorrhage is a crucial part of the immediate postoperative management of a client who has undergone gastric resection.

3. A client returns from surgery with a sigmoid colostomy. An ostomy appliance is attached. The priority nursing diagnosis for daily observation and care is:

Correct answer: B

Rationale: Impaired skin integrity would be the priority nursing diagnosis for daily care of the colostomy because the effluent from the colostomy can be irritating to the skin. Diarrhea isn't a concern at this point. The client will be allowed nothing by mouth until peristalsis returns. The client should get out of bed on the first postoperative day, so mobility shouldn't be a problem.

4. 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:

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.

5. The client being seen in a physician’s office has just been scheduled for a barium swallow the next day. The nurse writes down which of the following instructions for the client to follow before the test?

Correct answer: A

Rationale: A barium swallow is an x-ray study that uses a substance called barium for contrast to highlight abnormalities in the gastrointestinal tract. The client should fast for 8 to 12 hours before the test, depending on physician instructions. Most oral medications also are withheld before the test. After the procedure the nurse must monitor for constipation, which can occur as a result of the presence of barium in the gastrointestinal tract.
