Answer to Question 1

ANS: A
An agonist medication is one that stimulates a certain type of cell to produce a response.

Answer to Question 2

ANS: B
The onset of action is the time it takes to reach the MEC. Duration of action is the length of time a drug has a pharmacologic effect. Peak action time occurs when the drug reaches its highest blood level. The time response curve is an evaluation of the other three measures.
