1. What does a STAT medication order mean?
A) A medication that is given routinely every day
B) A medication that is given only when symptoms occur
C) A medication that is needed immediately and given only once
D) A medication that is given at bedtime
Correct Answer: C) A medication that is needed immediately and
given only once
Rationale: A STAT order indicates that the medication is needed
immediately and should be administered promptly as a one-time dose.
2. What information does the overdosage section of medication
labeling provide?
A) The medication's usual maintenance dose
B) Signs, symptoms, and treatment of acute overdoses
C) The medication's expiration date
D) Instructions for administering the medication with food
Correct Answer: B) Signs, symptoms, and treatment of acute
overdoses
,Rationale: The overdosage section describes manifestations that may
occur with an acute overdose and provides information regarding
appropriate treatment or management.
3. Which are types of drug-drug interactions?
A) Absorption, distribution, metabolism, and excretion
B) Potency, efficacy, tolerance, and dependence
C) Duplication, opposition (antagonism), and alteration
D) Agonism, absorption, elimination, and toxicity
Correct Answer: C) Duplication, opposition (antagonism), and
alteration
Rationale: Drug-drug interactions can involve duplication, in which
drugs have similar effects; opposition or antagonism, in which one drug
reduces the effect of another; and alteration, in which one drug changes
the absorption, metabolism, or elimination of another drug.
4. Which of the following correctly identifies the three major types
of drug-drug interactions?
A) Potency, efficacy, and tolerance
B) Duplication, opposition (antagonism), and alteration
C) Absorption, distribution, and excretion
D) Agonism, dependence, and toxicity
Correct Answer: B) Duplication, opposition (antagonism), and
alteration
,Rationale: The three major types of drug-drug interactions are
duplication, in which drugs have similar effects; opposition
(antagonism), in which one drug reduces or blocks the effect of another;
and alteration, in which one drug changes the absorption, metabolism,
or elimination of another drug.

and alteration, in which one drug changes the absorption, metabolism,
or elimination of another drug.
5. Which statement best distinguishes tolerance from resistance to a
drug?
A) Tolerance occurs when cells permanently become unable to respond
to a drug, while resistance occurs when the dose must be increased.
B) Tolerance and resistance are interchangeable terms describing the
, same process.
C) Tolerance refers only to antibiotic therapy, while resistance occurs
with all medications.
D) Tolerance is a diminished response to a drug, whereas resistance is
the ability of cells or organisms to resist the drug's effects.
Correct Answer: D) Tolerance is a diminished response to a drug,
whereas resistance is the ability of cells or organisms to resist the
drug's effects.
Rationale: Tolerance develops when a person has a reduced response
to a drug over time, often requiring a higher dose to achieve the same
effect. Resistance refers to cells or organisms being able to withstand or
resist the effects of a drug.
6. What is the primary purpose of an Abbreviated New Drug
Application (ANDA)?
A) To demonstrate that a generic drug is bioequivalent to the innovator
drug without duplicating unnecessary clinical testing
B) To establish a new drug's patent before clinical trials begin
C) To allow manufacturers to market a drug without FDA review
D) To require the generic manufacturer to repeat all clinical trials
conducted by the innovator
Correct Answer: A) To demonstrate that a generic drug is
bioequivalent to the innovator drug without duplicating
unnecessary clinical testing
Rationale: An ANDA is the FDA application process used for generic
drugs. The applicant must scientifically demonstrate that the generic
