True

Prunes are indeed an effective laxative. They are high in fiber and contain a natural laxative compound called sorbitol. Sorbitol helps to soften the stool and promote bowel movements, relieving constipation. Prunes also contain dihydrophenylisatin, a compound that stimulates the bowel muscles and aids in digestion. Therefore, consuming prunes can help regulate bowel movements and alleviate constipation, making them an effective natural laxative.Rate this question:

The drug LEAST likely to help constipation:
- A.
Psyllium (Metamucil)
- B.
Polyethylene glycol (Miralax)
- C.
Docusate (Colace)
- D.
Magnesium hydroxide suspension (Milk of Magnesia)
- E.
Lactulose (Enulose)
Correct Answer
C. Docusate (Colace)Explanation
Docusate (Colace) is the drug least likely to help constipation because it is a stool softener that works by increasing the amount of water in the stool, making it easier to pass. However, it does not stimulate bowel movements or provide any additional relief for constipation. Psyllium (Metamucil), Polyethylene glycol (Miralax), Magnesium hydroxide suspension (Milk of Magnesia), and Lactulose (Enulose) are all laxatives that can help relieve constipation by either softening the stool, increasing bowel movements, or both.Rate this question:
