Haveles: Applied Pharmacology for the Dental Hygienist, 9th Edition
MULTIPLE CHOICE
1. Knowledge of pharmacology aids the dental professional in
a. obtaining a patient’s health history.
b. administering drugs in the office.
c. handling emergency situations.
d. selection of a nonprescription medication.
e. All of the above.
ANSWER: E
All of the choices are true. Because many of our patients are being treated with drugs,
knowledge of pharmacology helps in understanding and interpreting patients’ responses
to health history questions. Knowledge of the therapeutic and adverse effects of
medications obviously helps in their proper administration in the office. Emergency
situations may be caused by drugs or treated by drugs; thus, knowledge of
pharmacology is of great help, especially because a rapid response is sometimes
required. A clear understanding of the concepts of drug action, drug handling by the
body, and drug interactions will allow the dental practitioner to make proper judgments
and grasp the concepts relevant to new drug therapies on the market.

b. Asthmatic patients should have dental appointments in the morning.
c. Diabetic patients usually have fewer problems with a morning appointment compared
with afternoon appointments.
d. Both B and C are true.
ANSWER: D
Asthmatic patients who experience dental anxiety should schedule their appointments
when they are not rushed or under pressure early in the morning. Diabetic patients
usually have relatively fewer problems with a morning appointment. Patients taking
medication for systemic diseases may require special handling in the dental office.

3. Nutritional or herbal supplements
a. carry the U.S. Food and Drug Administration (FDA) approval for disease states.
b. are not drugs.
c. can cause adverse effects.
d. will not interact with other drugs the patient may be taking.
ANSWER: C
Nutritional or herbal supplements are quite capable of causing adverse effects. The
majority of nutritional or herbal supplements do not carry FDA approval for treating
disease states. These supplements are drugs and can cause adverse effects and
interact with different drugs.

d. Trade name

ANSWER: C
Before any drug is marketed, it is given a generic name that becomes the “official” name
of the drug. Each drug is assigned only one generic name selected by the U.S. Adopted
Name Council, and the name is not capitalized. The brand name is equivalent to the
trade name and is capitalized. Although the brand name is technically the name of the
company marketing the product, this term is often used interchangeably with the trade
name. The code name is the initial term used within a pharmaceutical company to refer
to a drug while it is undergoing investigation and is often a combination of capital letters
and numbers, the letters representing an abbreviation of the company name.

5. A drug’s generic name is selected by the
a. pharmaceutical company manufacturing it.
b. Food and Drug Administration (FDA).
c. U.S. Adopted Name Council.
d. Federal Patent Office.
ANSWER: C
Each drug is assigned only one generic name (e.g., ibuprofen). It is selected by the U.S.
Adopted Name Council. The generic name is not selected by the FDA or the Federal
Patent Office. The pharmaceutical company manufacturing the drug clearly has an
influence on the generic name given its drug, but the final decision is not the company’s.

ANSWER: B
Each drug has only one generic name but may have several trade names. For each
drug, there is only one generic name. It is not capitalized, and it becomes the “official”
name of the drug. The pharmaceutical company discovering the drug gives the drug a
trade name. The trade name is protected by the Federal Patent Law for 20 years from
the earliest claimed filing date, plus patent term extensions. Although the brand name is
technically the name of the company marketing the product, it is often used
interchangeably with the trade name.

7. Two drugs that are found to be chemically equivalent, but not biologically equivalent
or therapeutically equivalent are said to differ in
a. potency.
b. efficacy.
c. bioavailability.
d. therapeutic index.
ANSWER: C
A preparation can be chemically equivalent yet not biologically or therapeutically
equivalent. These products are said to differ in their bioavailability. The potency of a
drug is a function of the amount of drug required to produce an effect. The efficacy is
the maximum intensity of effect or response that can be produced by a drug. The
therapeutic index is the ratio of the lethal dose for 50% of the experimental animals
divided by the effective dose for 50% of the experimental animals. If the value of the
therapeutic index is small, toxicity is more likely.
