Answer to Question 1

C

Answer to Question 2

C
Feedback:
Promethazine and other phenothiazines have widespread effects on the body. The therapeutic effects in nausea and vomiting are attributed to their ability to block dopamine from receptor sites in the brain and CTZ. This blockage of dopamine has the potential to exacerbate parkinsonian effects.
