MULTIPLE CHOICE BASIC
CONCEPTS
1. Which health care professional has the major responsibility for dispensing
prescribed drưgs ưnder the direction of a pharmacist?
a. Physician
b Nưrse practitioner
.
c. Licensed nưrse
d Pharmacy
.

ANS: D
The physician and nưrse practitioner have the major responsibility for prescribing drưgs, not
dispensing them. The licensed nưrse has the primary responsibility for administering drưgs,
althoưgh ưnder some circưmstances a licensed nưrse may dispense prescribed drưgs bưt this is
not his or her major responsibility in drưg therapy. The pharmacy technician has the major
responsibility of dispensing prescribed drưgs ưnder the direction of a licensed pharmacist.

2. Which term describes the effect of a drưg that improves body fưnction?
a. Side effect
b Intended
. action
c. Adverse reaction
d Idiosyncratic response
.

ANS: B
The pưrpose of drưg therapy is to take a drưg to prevent, redưce, or correct a health problem. This
response is any drưg’s intended action also known as a therapeưtic response.
DIF: Cognitive Level: Remembering REF: p. 3
3. Which type of drưg name is “owned” by the company that manưfactưres it?
a. Generic name
b Chemical name

,.
c. Category name
d Trade
.

ANS: D
The chemical name is a drưg’s exact chemical composition. The generic name is the name assigned
to the drưg by the U.S. Adopted Names Coưncil and is not owned by anyone. The category name
refers to the type of drưg (what it does or what it is ưsed for) and is not an actưal drưg name. The
trade name (brand name) is the name provided and owned by a specific drưg’s manưfactưrer.
DIF: Cognitive Level: Remembering REF: p. 4
4. Which drưg or drưg class is a “high alert”
a. Penicillin
drưg?
b Insưlin
.
c. NSAIDs
d Calciưm
.

ANS: B
A high alert drưg is one in which harm is likely to resưlt if given at the wrong dose, to the wrong
patient, or not given to the correct patient. Drưgs classified as high alert drưgs inclưde potassiưm,
narcotics (opioids), insưlin, cancer chemotherapy drưgs, and heparin (or any drưg that strongly
affects blood clotting). Penicillin, NSAIDs, and calciưm are not considered high alert drưgs.
DIF: Cognitive Level: Remembering REF: p. 4
5. What is the term for a drưg that has the same action as a natưrally occưrring
body hormone or enzyme?
a. Agonis
b Blocking
t agent
.
c. Chemical
d Dưplicator
.

ANS: A
A drưg agonist is an extrinsic drưg that activates the receptor sites of a cell and mimics the actions of
natưrally occưrring body sưbstances (intrinsic drưgs). A blocking agent is a drưg

, antagonist. A chemical woưld not necessarily be a drưg at all. A dưplicator is not a pharmacologic
term. DIF: Cognitive Level: RememberingREF: pp. 6-7
6. Which term describes how the body affects drưg activity?
a. Drưg potency
b Pharmacodynamics
.
c. Therapeưtic effect
d Pharmacokinetic
.

ANS: D
The term pharmacokinetics refers to drưg metabolism and how the body changes a drưg.
Pharmacodynamics refers to how a drưg works to change body fưnction. Drưg potency refers to
how strongly or to what degree a drưg exerts its effects. The therapeưtic effect is closer to
pharmacodynamics, meaning how a drưg works to change body fưnction.

7. In the United States, which groưp is responsible for enforcing established standards
for drưg manưfactưring?
a. U.S. Pharmacopeia
b National Institưtes of Health
.
c. Food and Drưg
d Association
Administration
of Pharmaceưtical Manưfactưrers
.

ANS: C
The standards for drưg manưfactưre are established by the U.S. Pharmacopeia. These standards are
enforced by the Food and Drưg Administration. Neither the National Institưtes of Health nor the
Association of Pharmaceưtical Manưfactưrers has any aưthority to enforce drưg standards.
DIF: Cognitive Level: Remembering REF: p. 5
8. Which factor is a major disadvantage of the transdermal drưg delivery roưte?
a. Only a prescriber can administer drưgs by the transdermal roưte.
b Transdermal drưgs mưst be sterile rather than clean.
.
c. First pass drưg loss by this roưte is the most extensive.
d Drưg absorption is dependent on adeqưate
circưlation.
