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 treatments is used for rectal cancer but not for colon cancer?

3. Jason, a 22 y.o. accident victim, requires an NG tube for feeding. What should you immediately do after inserting an NG tube for liquid enteral feedings?

Correct answer: A

4. The pain of a duodenal ulcer can be distinguished from that of a gastric ulcer by which of the following characteristics?

5. 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.
