Use the Mechanism of Action to Select the Statement That

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.
