Answer to Question 1

Ans: B
Feedback:
Side effects associated with SSRIs include nausea, vomiting, weight changes, agitation or restlessness, and delayed or impaired orgasm. Side effects are immediate; some experts believe that beginning with a subtherapeutic dose to improve initial tolerance can minimize side effects. Others posit that the starting dose should be the same as the maintenance dose. Side effects can be minimized by lowering the dose.

Answer to Question 2

Ans: A
Feedback:
Drug antagonists block the actions of everything in the agonist spectrum. These chemicals bind to and block a receptor, producing no response and preventing agonists from binding or attaching to the receptor.
