Stool softeners, like docusate sodium (Colace) and docusate calcium (Surfak), produce their laxative effect by promoting water retention in the fecal mass and softening the stool. Methylcellulose is a bulk-producing laxative. Bisacodyl is a stimulant laxative. Lactulose is a hyperosmolar laxative.

Answer to Question 2

Ans: C, E
Feedback:
Hyperosmotic agents, like glycerin (Fleet Babylax) and lactulose (Chronulac), produce their laxative effect by dehydrating local tissues, which causes irritation and increased peristalsis, with consequent evacuation of the fecal mass. Docusate is a stool softener. Methylcellulose is a bulk-forming laxative. Bisacodyl is an irritant laxative.
