MULTIPLE CHOICE

1. A drug is defined as a biologically active substance that can modify:
a. the environment.
b. the pH of tissue.
c. cellular function.
d. immune response.



ANS: C
Correct: A drug can modify cellular function. A general understanding of drug action allows
the dental hygienist to make informed decisions regarding possible drug interactions or
adverse reactions for the patient.
Incorrect choices: It is a concern that discarded drugs may be affecting the environment, but this
is not the definition of a drug. Some drugs may have the capacity to modify body compartment
pH; however, this is not the definition for a drug. Some drugs may have the capacity to modify
the immune response, but this is not the definition of a drug.

2. In comparing two drugs, the dose-response curve for the drug that is more efficacious
would: a. be closer to the y axis.
b. be farther from the y axis.

c.d. have a greater curve height.have a higher median effective dose (EDNU RSINGTB50.).C OM



ANS: C
Correct: Efficacy is an expression of maximum intensity of effect or response that can be produced
by a drug.
Incorrect choices: The other choices refer to indicators of drug potency, not efficacy. The
potency of a drug is a function of the amount of drug required to produce an effect. The
potency of drug is shown by the location of that drug’s curve along the log-dose axis (x axis).
