Which statement is FALSE regarding 5HT-3 RAs?

Used for acute and delayed CINV
Not to be used with apomorphine
Can increase QT interval
May cause serotonin syndrome

The correct answer is: Used for acute and delayed CINV

5HT-3 RAs can cause a number of adverse side effects, including increasing the QT interval and potentially causing serotonin syndrome. While they are typically used for the treatment of both acute and delayed chemotherapy-induced nausea and vomiting (CINV), this statement is FALSE. 5HT-3 RAs should not be used concomitantly with apomorphine, not used for both acute and delayed CINV. This option is incorrect because it is not consistent with the indications for 5HT-3 RAs. The other two choices are also incorrect because they list potential side effects of 5HT-3 RAs, not statements that are false regarding their use.
