c. handling emergency situations. WS WS




d. selection of a nonprescription medication. WS WS WS WS




e. All of the above. WS WS WS

All of the choices are true. Because many of our patients are being treated with drugs, knowledge of p

harmacology helps in understanding and interpreting patients’ responses to health history questions. K

WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS

WS WS WS WS WS WS WS WS WS




a. Whether or not patients are taking medication for systemic diseases is of little

d. Both B and C are true. WS WS WS WS WS




ANS: D W S




Asthmatic patients who experience dental anxiety should schedule their appointments when they are n

a. carry the U.S. Food and Drug Administration (FDA) approval for disease states.
WS WS WS WS WS WS WS WS WS WS WS




b. are not drugs. WS WS




c. can cause adverse effects. WS WS WS




d. will not interact with other drugs the patient may be taking.
WS WS WS WS WS WS WS WS WS WS




ANS: C W S




Nutritional or herbal supplements are quite capable of causing adverse effects. The majority of nutrition
WS WS WS WS WS WS WS WS WS WS WS WS WS WS




al or herbal supplements do not carry FDA approval for treating disease states. These supplements are
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




drugs and can cause adverse effects and interact with different drugs.

4. Which type of drug name usually begins with a lowercase letter?
WS WS WS WS WS WS WS WS WS WS




a. Brand name WS




b. Code name WS




c. Generic name WS




d. Trade name WS




ANS: C W S




Before any drug is marketed, it is given a generic name that becomes the “official” name of the drug.
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




Each drug is assigned only one generic name selected by the U.S. Adopted Name Council, and the na
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




me is not capitalized. The brand name is equivalent to the trade name and is capitalized. Although the
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS W




brand name is technically the name of the company marketing the product, this term is often used inter
S WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




changeably with the trade name. The code name is the initial term used within a pharmaceutical comp

any to refer to a drug while it is undergoing investigation and is often a combination of capital letters

WS WS WS WS WS WS WS




a. pharmaceutical company manufacturing it. WS WS WS




b. Food and Drug Administration (FDA). WS WS WS WS




c. U.S. Adopted Name Council. WS WS WS




d. Federal Patent Office. WS WS




ANS: C W S




Each drug is assigned only one generic name (e.g., ibuprofen). It is selected by the U.S. Adopted Na

7. Two drugs that are found to be chemically equivalent, but not biologically equivalent or

therapeutically equivalent are said to differ in WS WS WS WS WS WS




a. potency.
b. efficacy.
c. bioavailability.
d. therapeutic index. WS




ANS: C W S




A preparation can be chemically equivalent yet not biologically or therapeutically equivalent. These p
WS WS WS WS WS WS WS WS WS WS WS WS WS




roducts are said to differ in their bioavailability. The potency of a drug is a function of the amount of d
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




rug required to produce an effect. The efficacy is the maximum intensity of effect or response that can
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




be produced by a drug. The therapeutic index is the ratio of the lethal dose for 50% of the experiment
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




al animals divided by the effective dose for 50% of the experimental animals. If the value of the thera
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS
