1. Which health care professional has the major responsibility for dispensing
nm nm nm nm nm nm nm nm nm


prescribed drugs under the direction of a pharmacist?
nm nm nm nm nm nm nm nm


a. Physician
b Nurse practitioner nm


.
c. Licensed nurse nm


d Pharmacy technician nm


.


ANS: D n m


The physician and nurse practitioner have the major responsibility for prescribing drugs,
nm nm nm nm nm nm nm nm nm nm nm


not dispensing them. The licensed nurse has the primary responsibility for
nm nm nm nm nm nm nm nm nm nm nm


administering drugs, although under some circumstances a licensed nurse may dispense
nm nm nm nm nm nm nm nm nm nm nm


prescribed drugs but this is not his or her major responsibility in drug therapy. The
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


pharmacy technician has the major responsibility of dispensing prescribed drugs under
nm nm nm nm nm nm nm nm nm nm nm


the direction of a licensed pharmacist.

2. Which term describes the effect of a drug that improves body function?
nm nm nm nm nm nm nm nm nm nm nm


a. Side effectnm


b Intended action nm


.
c. Adverse reaction nm


d Idiosyncratic response nm


.


ANS: B n m


The purpose of drug therapy is to take a drug to prevent, reduce, or correct a health
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


problem. This response is any drug’s intended action also known as a therapeutic
nm nm nm nm nm nm nm nm nm nm nm nm nm


response.

3. Which type of drug name is ―owned‖ by the company that manufactures it?
nm nm nm nm nm nm nm nm nm nm nm nm


a. Generic name nm


b Chemical name nm

, .
c. Category name nm


d Trade name nm


.


ANS: D n m


The chemical name is a drug’s exact chemical composition. The generic name is the
nm nm nm nm nm nm nm nm nm nm nm nm nm


name assigned to the drug by the U.S. Adopted Names Council and is not owned by
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


anyone. The category name refers to the type of drug (what it does or what it is used
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


for) and is not an actual drug name. The trade name (brand name) is the name
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


provided and owned by a specific drug’s manufacturer.

4. Which drug or drug class is a ―high alert‖ drug?
nm nm nm nm nm nm nm nm nm


a. Penicillin
b Insulin
.
c. NSAIDs
d Calcium
.


ANS: B n m


A high alert drug is one in which harm is likely to result if given at the wrong dose,
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


to the wrong patient, or not given to the correct patient. Drugs classified as high alert
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


drugs include potassium, narcotics (opioids), insulin, cancer chemotherapy drugs, and
nm nm nm nm nm nm nm nm nm nm


heparin (or any drug that strongly affects blood clotting). Penicillin, NSAIDs, and
nm nm nm nm nm nm nm nm nm nm nm nm


calcium are not considered high alert drugs.

5. What is the term for a drug that has the same action as a naturally
nm nm nm nm nm nm nm nm nm nm nm nm nm nm


occurring body hormone or enzyme?
nm nm nm nm nm


a. Agonist
b Blocking agent nm


.
c. Chemical
d Duplicator
.


ANS: A n m


A drug agonist is an extrinsic drug that activates the receptor sites of a cell and mimics
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


the actions of naturally occurring body substances (intrinsic drugs). A blocking agent is
nm nm nm nm nm nm nm nm nm nm nm nm nm


a drug
nm nm

, antagonist. A chemical would not necessarily be a drug at all. A duplicator is not a
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


pharmacologic term.

6. Which term describes how the body affects drug activity?
nm nm nm nm nm nm nm nm


a. Drug potency nm


b Pharmacodynamics
.
c. Therapeutic effect nm




d Pharmacokinetics
.


ANS: D n m


The term pharmacokinetics refers to drug metabolism and how the body changes a
nm nm nm nm nm nm nm nm nm nm nm nm


drug. Pharmacodynamics refers to how a drug works to change body function. Drug
nm nm nm nm nm nm nm nm nm nm nm nm nm


potency refers to how strongly or to what degree a drug exerts its effects. The
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm


therapeutic effect is closer to pharmacodynamics, meaning how a drug works to
nm nm nm nm nm nm nm nm nm nm nm nm


change body function.

7. In the United States, which group is responsible for enforcing established
nm nm nm nm nm nm nm nm nm nm


standards for drug manufacturing?
nm nm nm nm


a. U.S. Pharmacopeia
nm


b National Institutes of Health nm nm nm


.
c. Food and Drug Administration
nm nm nm


d Association of Pharmaceutical nm nm


. Manufacturers
nm




ANS: C n m


The standards for drug manufacture are established by the U.S. Pharmacopeia. These
nm nm nm nm nm nm nm nm nm nm nm


standards are enforced by the Food and Drug Administration. Neither the National
nm nm nm nm nm nm nm nm nm nm nm nm


Institutes of Health nor the Association of Pharmaceutical Manufacturers has any
nm nm nm nm nm nm nm nm nm nm nm


authority to enforce drug standards.

8. Which factor is a major disadvantage of the transdermal drug delivery route?
nm nm nm nm nm nm nm nm nm nm nm


a. Only a prescriber can administer drugs by the transdermal
nm nm nm nm nm nm nm nm


route.
nm


b Transdermal drugs must be sterile rather than clean.nm nm nm nm nm nm nm


.
c. First pass drug loss by this route is the most extensive.
