Answer to Question 1

B
Feedback:
Phenothiazines are centrally acting antiemetics, which change the responsiveness or stimulation of the CTZ in the medulla.

Answer to Question 2

D

Most can be managed through diet or over-the-counter medications but a rash needs to be reported immediately because it could indicate a potentially serious reaction and requires immediate intervention.
