Answer to Question 1

ANS: A
Intestinal flora have the ability to metabolize digoxin, and any drug that destroys or inhibits growth of these gastrointestinal microflora can increase digoxin levels leading to toxicity.

Answer to Question 2

ANS: B
Drug interactions are an altered or modified action or effect of a drug as a result of interaction with one or more other drugs. An adverse drug reaction can occur with one or more drugs and has effects ranging from mild to severe toxicity. Drug incompatibility is a chemical reaction of two or more drugs that occurs in vitro. Drug tolerance is the development of reduced response to a medication over time.
