Question 1 of 5
Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?
Correct Answer: B
Rationale: Zofran is a serotonin antagonist that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.
