Which type of laxative, as its mechanism of action, pulls water into the fecal mass to create a more watery stool?
 
  1. Bulk-forming laxatives
  2. Saline cathartics
  3. Surfactant laxatives
  4. Stimulant laxatives

Question 2

The nurse demonstrates knowledge of the different mechanisms of action of laxatives by stating:
 
  1. My client should be encouraged to use a stimulant laxative whenever he feels the need to have a bowel movement.
  2. My client should consume plenty of water, since he is taking a bulk-forming laxative.
  3. My client should not strain when having a bowel movement, so the health care provider likely will prescribe a bulk-forming laxative.
  4. My client should expect to have a delayed reaction to a saline cathartic.

Answer to Question 1

Correct Answer: 2
Rationale 1: Bulk-forming agents absorb water, thus adding size to the fecal mass.
Rationale 2: Saline cathartics, also called osmotic laxatives, are poorly absorbed in the intestine. They pull water into the fecal mass to create a more watery stool.
Rationale 3: Surfactants, commonly called stool softeners, cause more water and fat to be absorbed into the stools.
Rationale 4: Stimulant laxatives promote peristalsis by irritating the bowel.

Answer to Question 2

Correct Answer: 2
Rationale 1: Stimulant laxatives should not be used routinely because they can cause laxative dependence, abdominal cramping, and depletion of fluid and electrolytes.
Rationale 2: Because fiber absorbs water and expands to provide bulk, bulk-forming laxatives must be taken with plenty of water.
Rationale 3: A bulk-forming laxative can cause a client to have to strain to have a bowel movement, especially when the client does not consume plenty of water.
Rationale 4: Saline cathartics can produce a bowel movement very quickly.
