What is the term for a drug that has the same action as a
naturally occurring body hormone or enzyme?
a. Agonist
b Blocking
. agent
c. Chemical
d Duplicator
,.
ANS: A
A drug agonist is an extrinsic drug that activates the receptor sites of a
cell and mimics the actions of naturally occurring body substances
(intrinsic drugs). A blocking agent is a drug
, antagonist. A chemical would not necessarily be a drug at all. A duplicator is
not a pharmacologic term.

Which term describes how the body affects drug activity?
a. Drug potency
b Pharmacodyna
. mics
c. Therapeutic
effect
d Pharmacokineti
. cs
ANS: D
The term pharmacokinetics refers to drug metabolism and how the body
changes a drug. Pharmacodynamics refers to how a drug works to change body
function. Drug potency refers to how strongly or to what degree a drug exerts
its effects. The therapeutic effect is closer to pharmacodynamics, meaning how
a drug works to change body function.
