Answer to Question 1

ANS: A, C, E
Cigarette smoking increases acid secretion and alters blood flow to the stomach. In addition, cigarette smoking interferes with prostaglandin synthesis, which compromises defense mechanisms. A genetic predisposition seems to exist for the development of PUD. Infection by H. pylori is thought to be associated with as many as 90 of duodenal and 70 of gastric ulcers. Chronic emotional stress was previously believed to cause stress ulcers, and physicians suggested that patients with this condition reduce their stress levels. However, patients who took steps to reduce the stress in their lives saw no improvement. It is now known that emotional stress does not cause ulcers, but it may make them worse. Bacteria have been shown to cause a stress ulcer, which can be treated simply by taking a dose of antibiotics. Dairy products do not contribute to the development of ulcers.

Answer to Question 2

ANS: C, D
H2 antagonists and proton pump inhibitors are used to reduce gastric acid secretion. Prokinetic agents are used to hasten emptying of the stomach to reduce reflux. Antacids neutralize gastric acid. Coating agents are given to form a barrier in the stomach.
