Answer to Question 1

ANS: D
Stimulant laxatives act directly on the intestine, causing an irritation that promotes peristalsis and evacuation. Saline laxatives draw water into the bowel to facilitate the passage of feces. Lubricant laxatives lubricate the intestinal wall and soften the stool, allowing a smooth passage of fecal contents. Bulk-producing laxatives must be administered with a full glass of water. The laxative causes water to be retained within the stool. This increases bulk, which stimulates peristalsis.

Answer to Question 2

ANS: A
Methylnaltrexone is used for the treatment of opioid-induced constipation in patients with advanced illness who are receiving palliative care when their response to laxative therapy has not been adequate. Bisacodyl, mineral oil, and docusate are not the treatment of choice for this situation.
