Answer to Question 1

ANS: D
When drugs are equally protein bound, they will vie for receptor sites. More of both drugs will be displaced, allowing for a greater level of medication activity.

Answer to Question 2

ANS: A
Because of slower gastric emptying time, drugs have more chance to be absorbed.
