question 17

Multiple Choice

Use the mechanism of action to select the statement that best describes how you would explain to a patient how the adsorbent class of drugs used in the treatment of simple diarrhea works.

• A) The adsorbents work in the intestine to form a complex with irritating substances such as bacteria, digestive enzymes, or toxins and carry them into the feces for elimination.
• B) The adsorbents remain in the intestine, soak up water, and expand. The water, which is retained, softens the stool, and the swelling action distends the rectum and initiates defecation.
• C) The adsorbents are a mixture of sodium and magnesium salts. These ions attract water, which causes a more liquid stool to be formed.
• D) The adsorbents act on the stool to permit water to penetrate the fecal mass. The oily nature of these laxatives eases the passage of the stool through the rectum.
