The nurse is reviewing a client's daily medications taken at home. Which of the following medications has a risk of dependency if used daily?

Choice A reason: Psyllium (Metamucil) is a bulk-forming laxative used to treat constipation. It works by absorbing water into the intestine to form a bulky, soft stool, which is easier to pass. Psyllium is generally safe for long-term use and does not carry a risk of dependency. It is considered one of the gentler options for managing chronic constipation and is often recommended as a first-line treatment. Choice B reason: Polyethylene glycol (MiraLAX) is an osmotic laxative that works by retaining water in the stool, resulting in softer stools and easier bowel movements. It is also considered safe for short-term use but can be used long-term under medical supervision without a significant risk of dependency. Unlike stimulant laxatives, polyethylene glycol does not cause the bowel to become reliant on it for regular movements. Choice C reason: Ondansetron (Zofran) is an antiemetic used to prevent nausea and vomiting associated with surgery, chemotherapy, or radiation therapy. It works by blocking serotonin receptors in the brain and gut. Ondansetron does not have a risk of dependency and is not used for constipation or bowel regulation, making it irrelevant in the context of laxative dependency. Choice D reason: Bisacodyl (Dulcolax) is a stimulant laxative that directly stimulates the nerve endings in the walls of the intestines, causing bowel contractions. Because it forces the bowel to contract, it can lead to dependency if used daily over a long period. The bowel can become reliant on the stimulant action to produce bowel movements, leading to decreased bowel function without the medication. Therefore, bisacodyl carries a higher risk of dependency compared to other types of laxatives.
