TEST BANK FOR UNDERSTANDING PHARMACOLOGY,
ESSENTIALS FOR MEDICATION SAFETY, 3RD EDITION




MULTIPLE CHOICE BASIC

,CONCEPTS

1. Which health care professional has the major responsibility for dispensing
prescribed medical drugs under the direction of a pharmacist?
a. Physician
b Nursing attendant
. practitioner
c. Licensed nursing
attendant
d Pharmacy
. technician


ACCURATE RESPONSE:-D
Review feedback:->>>The physician and nursing attendant have the major responsibility
for prescribing medical drugs, not dispensing them. The licensed nursing attendant has
the primary responsibility for administering medical drugs, although under some
circumstances a licensed nursing attendant may dispense prescribed medical drugs but
this is not his or her major responsibility in medical drug therapy. The pharmacy
technician has the major responsibility of dispensing prescribed medical drugs under the
direction of a licensed pharmacist.

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


ACCURATE RESPONSE:-B
Review feedback :->>>The aim of medical drug therapy is to take a medical drug to
prevent, lessen, or correct a health problem. This response is any medical drug’s intended
action also known as a therapeutic response.

3. Which type of medical drug name is “owned” by the company that manufactures it?
a. Generic name
b Chemical name

.
c. Category name
d Trade name
.


ACCURATE RESPONSE:-D
Review feedback:->>>The chemical name is a medical drug’s exact chemical composition.
The generic name is the name assigned to the medical drug by the U.S. Adopted Names
Council and is not owned by anyone. The category name refers to the type of medical drug

,(what it does or what it is used for) and is not an actual medical drug name. The trade
name (brand name) is the name provided and owned by a specific medical drug’s
manufacturer.

4. Which medical drug or medical drug class is a “high alert” medical drug?
a. Penicillin
b Insulin
.
c. NSAIDs
d Calcium
.


ACCURATE RESPONSE:-B
Review feedback:->>>A high alert medical drug is one in which harm is likely to result if
given at the wrong dose, to the wrong hospital client, or not given to the correct hospital
client. Medical drugs classified as high alert medical drugs include potassium, narcotics
(opioids), insulin, cancer chemotherapy medical drugs, and heparin (or any medical drug
that strongly affects blood clotting). Penicillin, NSAIDs, and calcium are not considered
high alert medical drugs.

5. What is the term for a medical drug that has the same action as a naturally
occurring body hormone or enzyme?
a. Agonist
b Blocking agent
.
c. Chemical
d Duplicator
.


ACCURATE RESPONSE:- A
Review feedback:->>>A medical drug agonist is an extrinsic medical drug that activates
the receptor sites of a cell and mimics the actions of naturally occurring body substances
(intrinsic medical drugs). A blocking agent is a medical drug antagonist. A chemical would
not necessarily be a medical drug at all. A duplicator is not a pharmacologic term.

6. Which term describes how the body affects medical drug activity?
a. Medical drug
potency
b Pharmacodynamic
. s
c. Therapeutic effect
d Pharmacokinetics
.


ACCURATE RESPONSE:-D

, Review feedback:->>>The term pharmacokinetics refers to medical drug metabolism and
how the body changes a medical drug. Pharmacodynamics refers to how a medical drug
works to change body function. Medical drug potency refers to how strongly or to what
degree a medical drug exerts its effects. The therapeutic effect is closer to
pharmacodynamics, meaning how a medical drug works to change body function.

7. In the United States, which group is responsible for enforcing established
standards for medical drug manufacturing?
a. U.S. Pharmacopeia
b National Institutes of Health
.
c. Food and Medical drug Administration
d Association of Pharmaceutical
. Manufacturers


ACCURATE RESPONSE:-C
Review feedback:->>>The standards for medical drug manufacture are established by the
U.S. Pharmacopeia. These standards are enforced by the Food and Medical drug
Administration. Neither the National Institutes of Health nor the Association of
Pharmaceutical Manufacturers has any authority to enforce medical drug standards.

8. Which factor is a major disadvantage of the transdermal medical drug delivery route?
a. Only a prescriber can administer medical drugs by the
transdermal route.
b Transdermal medical drugs must be sterile rather than clean.
.
c. First pass medical drug loss by this route is the most
extensive.
d Medical drug absorption is dependent on adequate
circulation.




ACCURATE RESPONSE:-D
Review feedback:->>>Once a transdermal medical drug moves through the skin, it must
enter the bloodstream to reach its target tissue. If circulation is poor to the area where the
transdermal medical drug is applied, very little, if any, of the medical drug will reach its
target tissue.

9. How are intrinsic medical drugs different from extrinsic medical drugs?
a. Intrinsic medical drugs are made by the body, whereas extrinsic medical drugs are
made outside the body.
b Intrinsic medical drugs are administered by the parenteral route, whereas extrinsic
. medical drugs are administered by the oral route.
c. Extrinsic medical drugs can only be applied to the skin or mucous membranes,
whereas intrinsic medical drugs are taken internally.
