Answer to Question 1

The phenothiazines, such as prochlorperazine, suppress nausea and vomiting by blockade of do-pamine receptors in the chemoreceptor trigger zone (CTZ).

Answer to Question 2

ANS: D
Although unusual when used for nausea and vomiting, phenothiazines have a variety of serious adverse effects, including extrapyramidal reactions such as pseudoparkinsonism, dystonia, aka-thisia, and tardive dyskinesia.
