Answer to Question 1

ANS: C
Only drugs not bound to protein are active and can cause a pharmacologic response. As the free drug in the circulation decreases, more bound drug is released from the protein to maintain the balance of free drug.

Answer to Question 2

ANS: B
The half-life (t ) of a drug is the time it takes for one half of the drug concentration to be eliminated.
