A nurse is providing an in-service regarding gastrointestinal (GI) medications. Complete the following sentences with the appropriate responses.
Surfactant laxatives, such as dropdown ( Docusate sodium, bisacodyl, Polyethylene glycol), lower surface tension of the stool to allow penetration of water. This softens the stool so it can be passed more easily.
On the other hand, dropdown ( Metronidazole, morphine, Loperamide) is used to prevent diarrhea.
The Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C"}
- Docusate sodium: This is a surfactant laxative that helps soften stools by allowing water and fats to penetrate the stool, making it easier to pass.
- Loperamide: This medication is an anti-diarrheal agent that works by slowing down gut movement, which helps reduce the frequency of diarrhea.

Correct Answer is D
Explanation
A. Ondansetron agonizes serotonin receptors on afferent vagal neurons. – This is incorrect. Ondansetron works by blocking, not activating, serotonin (5-HT3) receptors in areas involved in nausea and vomiting.
B. Ondansetron agonizes serotonin receptors in the medulla oblongata. – This is incorrect. Ondansetron does not act as an agonist at serotonin receptors in the medulla oblongata; instead, it antagonizes receptors to reduce nausea.
C. Ondansetron agonizes dopaminergic receptors in the vestibular apparatus. – This is incorrect. Ondansetron does not affect dopaminergic receptors or the vestibular apparatus. Medications like promethazine address dopaminergic pathways.
D. Ondansetron blocks serotonin receptors in the chemoreceptor trigger zone. – This is correct. Ondansetron acts as a 5-HT3 receptor antagonist, blocking serotonin receptors in the chemoreceptor trigger zone and vagal nerve terminals, effectively preventing nausea and vomiting.
Correct Answer is D
Explanation
A. "This medication may cause increased libido." This is incorrect. Cimetidine (Tagamet) can cause side effects such as decreased libido, especially in men. This occurs because the drug inhibits the action of certain hormones, leading to sexual dysfunction.
B. "You may take this medication with antacids to prevent stomach upset." This is incorrect. Cimetidine should not be taken with antacids because antacids can reduce its absorption and effectiveness. It is advised to space the administration of cimetidine and antacids by at least 1 hour.
C. "This medication will neutralize your stomach acid." This is incorrect. Cimetidine works by blocking histamine receptors (H2 receptors), which reduces the production of stomach acid but does not neutralize it.
D. "This medication may cause decreased libido." This is correct. One of the side effects of cimetidine is reduced libido, particularly in male clients, due to its anti-androgenic effects.
