CONCEPTS

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



prescribed drugs under the direction of a pharmacist?
m/ m/ m/ m/ m/ m/ m/ m/



a. Physician
b Nurse practitioner m/



.
c. Licensed nurse m/



d Pharmacy technician m/



.


ANS: D m /



The physician and nurse practitioner have the major responsibility for prescribing drugs, not
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



dispensing them. The licensed nurse has the primary responsibility for administering drugs,
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



although under some circumstances a licensed nurse may dispense prescribed drugs but this is
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



not his or her major responsibility in drug therapy. The pharmacy technician has the major
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



responsibility of dispensing prescribed drugs under the direction of a licensed pharmacist.

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



a. Side effect m/




b Intended action m/



.
c. Adverse reaction m/




d Idiosyncratic response m/



.


ANS: B m /



The purpose of drug therapy is to take a drug to prevent, reduce, or correct a health problem.
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



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

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



a. Generic name m/



b Chemical name m/

, .
c. Category name m/




d Trade name m/



.


ANS: D m /



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



assigned to the drug by the U.S. Adopted Names Council and is not owned by anyone. The
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



category name refers to the type of drug (what it does or what it is used for) and is not an
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



actual drug name. The trade name (brand name) is the name provided and owned by a
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



specific drug’s manufacturer.

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



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


ANS: B m /



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



wrong patient, or not given to the correct patient. Drugs classified as high alert drugs include
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



potassium, narcotics (opioids), insulin, cancer chemotherapy drugs, and heparin (or any drug
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



that strongly affects blood clotting). Penicillin, NSAIDs, and calcium are not considered high
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



alert drugs.

5. What is the term for a drug that has the same action as a naturally occurring
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



body hormone or enzyme?
m/ m/ m/ m/



a. Agonist
b Blocking agent m/



.
c. Chemical
d Duplicator
.


ANS: A m /



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



actions of naturally occurring body substances (intrinsic drugs). A blocking agent is a drug
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/

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



pharmacologic term.

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



a. Drug potency m/



b Pharmacodynamics
.
c. Therapeutic effect m/




d Pharmacokinetics
.


ANS: D m /



The term pharmacokinetics refers to drug metabolism and how the body changes a drug.
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



Pharmacodynamics refers to how a drug works to change body function. Drug potency refers
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



to how strongly or to what degree a drug exerts its effects. The therapeutic effect is closer to
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



pharmacodynamics, meaning how a drug works to change body function.

7. In the United States, which group is responsible for enforcing established standards
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



for
m/ m/ drug manufacturing?m/



a. U.S. Pharmacopeia m/



b National Institutes of Health m/ m/ m/



.
c. Food and Drug Administration
m/ m/ m/




d Association of Pharmaceutical Manufacturers m/ m/ m/



.


ANS: C m /



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



standards are enforced by the Food and Drug Administration. Neither the National Institutes
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



of Health nor the Association of Pharmaceutical Manufacturers has any authority to enforce
m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/ m/



drug standards.

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



a. Only a prescriber can administer drugs by the transdermal
m/ m/ m/ m/ m/ m/ m/ m/



route. m/



b Transdermal drugs must be sterile rather than clean. m/ m/ m/ m/ m/ m/ m/



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