5-HT3 antagonist work by blocking enterochromaffin cells in the GI and blocking serotonin receptors in the medulla.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
5-HT3 antagonists are a class of drugs that work by blocking the action of serotonin (5-HT3) receptors. These receptors are found in both the gastrointestinal (GI) tract and the medulla, which is a part of the brainstem. By blocking these receptors, 5-HT3 antagonists can prevent the activation of enterochromaffin cells in the GI tract, which are involved in the release of serotonin. Additionally, blocking serotonin receptors in the medulla can help to reduce nausea and vomiting, making 5-HT3 antagonists useful in the treatment of these symptoms. Therefore, the statement that 5-HT3 antagonists work by blocking enterochromaffin cells in the GI and blocking serotonin receptors in the medulla is true.Rate this question:

When used for PONV, Aprepitant should be given within 3 hours prior to induction.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Aprepitant is a medication commonly used to prevent postoperative nausea and vomiting (PONV). It belongs to a class of drugs known as neurokinin-1 receptor antagonists. The timing of administration is crucial for its effectiveness. Giving Aprepitant within 3 hours prior to the induction of anesthesia ensures that the drug reaches peak concentration in the body by the time surgery begins. This allows it to effectively block the neurokinin-1 receptors and prevent the occurrence of PONV. Therefore, the statement "When used for PONV, Aprepitant should be given within 3 hours prior to induction" is true.Rate this question:
