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



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



a. Physician
b Nurse practitioner mm



.
c. Licensed nurse mm



d Pharmacy technician mm



.


ANS: D m m



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



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



drugs, although under some circumstances a licensed nurse may dispense prescribed drugs
mm mm mm mm mm mm mm mm mm mm mm mm



but this is not his or her major responsibility in drug therapy. The pharmacy technician
mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm



has the major responsibility of dispensing prescribed drugs under the direction of a
mm mm mm mm mm mm mm mm mm mm mm mm mm



licensed pharmacist.

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



a. Side effect mm




b Intended action mm



.
c. Adverse reaction mm




d Idiosyncratic response mm



.


ANS: B m m



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



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



response.

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



a. Generic name mm



b Chemical name mm

, .
c. Category name mm




d Trade name mm



.


ANS: D m m



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



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



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



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



and owned by a specific drug’s manufacturer.

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



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


ANS: B m m



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



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



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



(or any drug that strongly affects blood clotting). Penicillin, NSAIDs, and calcium are
mm mm mm mm mm mm mm mm mm mm mm mm mm



not considered high alert drugs.

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



occurring body hormone or enzyme?
mm mm mm mm mm



a. Agonist
b Blocking agent mm



.
c. Chemical
d Duplicator
.


ANS: A m m



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



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



drug
mm

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



pharmacologic term.

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



a. Drug potency mm



b Pharmacodynamics
.
c. Therapeutic effect mm




d Pharmacokinetics
.


ANS: D m m



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



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



refers to how strongly or to what degree a drug exerts its effects. The therapeutic effect
mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm



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

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



standards for drug manufacturing?
mm mm mm mm



a. U.S. Pharmacopeia mm



b National Institutes of Health mm mm mm



.
c. Food and Drug Administration
mm mm mm




d Association of Pharmaceutical mm mm



. Manufacturers
mm




ANS: C m m



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



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



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



authority to enforce drug standards.

mm mm mm mm mm mm mm mm mm mm mm



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



route.mm



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



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