Answer to Question 1

ANS: D
Magnesium oxide, magnesium hydroxide, and magnesium trisilicate are used in antacid preparations. All magnesium products can cause diarrhea. Milk of Magnesia is often taken for constipation. Antacids are given to relieve heartburn. Calcium-based antacids are likely to cause rebound indigestion. Magnesium is often given as a laxative, in antacid form or as magnesium sulfate.

Answer to Question 2

ANS: B
Prokinetic agents increase the lower esophageal sphincter muscle pressure and peristalsis, hastening emptying of the stomach to reduce reflux. Metoclopramide increases lower esophageal sphincter pressure. Metoclopramide hastens gastric emptying. Metoclopramide is a prokinetic agent and does not affect motor function.
