Answer to Question 1
ANS: C
Patients who are not eating still secrete hydrochloric acid from the stomach's parietal cells. H2 receptor antagonists block the H2 receptors, resulting in a decrease in the amount of acid secreted. The pH of the stomach contents then becomes less acidic, which reduces the stress of the mucosal lining of the stomach. Ranitidine causes the stomach contents to become less acidic as the amount of acid secreted decreases; consequently, the pH of the stomach rises. This is not a coating agent, and giving it parenterally will not work to coat the stomach. Increased gastric acid, not nasogastric tubes, causes peptic ulcer disease (PUD).
Answer to Question 2
ANS: A
Metoclopramide is a gastric stimulant used to relieve the symptoms of gastric reflux esophagitis and diabetic gastroparesis, aid in small bowel intubation, and stimulate gastric emptying and intestinal transit of barium after radiologic examination of the upper gastrointestinal (GI) tract. Misoprostol is used to prevent and treat gastric ulcers caused by NSAIDs, including aspirin. Pantoprazole and ranitidine do not treat gastroparesis.
