NAPSRX CNPR EXAM |160 QUESTIONS
WITH 100% CORRECT ANSWERS (REVISED
18TH EDITION) |VERIFIED | UPDATED
1. What does a STAT order mean?
A) A drug needed for long-term therapy
B) A drug needed immediately and given only once
C) A drug needed only for chronic conditions
D) A drug prescribed for prophylaxis
Correct Answer: B
Rationale: A STAT order indicates that the medication must be administered
immediately, typically in emergency or urgent care situations. This is a single-dose
administration, ensuring rapid therapeutic effect. Medical staff must prioritize these
orders above routine medications to prevent patient harm.
2. What information does the overdosage section of drug labeling
provide?
A) Recommended diet with the drug
B) Signs, symptoms, and treatment of acute overdoses
C) Pharmacokinetic properties of the drug
D) Drug manufacturing details
Correct Answer: B
,Rationale: The overdosage section helps healthcare professionals identify clinical
manifestations of overdoses and provides steps for immediate intervention. Early
recognition and proper treatment can prevent severe toxicity or death. This
information is critical in emergency and inpatient care settings.
3. Types of drug-drug interactions include:
A) Duplication, opposition (antagonism), and alteration
B) Only chemical interactions
C) Additive effects only
D) None of the above
Correct Answer: A
Rationale: Drug-drug interactions can occur when two drugs influence each other’s
effects. Duplication leads to additive effects, opposition (antagonism) reduces
effectiveness, and alteration modifies metabolism or distribution. Understanding these
mechanisms prevents adverse effects and ensures therapeutic efficacy.
4. Tolerance vs Resistance
A) Tolerance is the cells’ ability to resist effects; resistance is diminished response
B) Tolerance is diminished response to a drug; resistance is the cells’ ability to resist
effects of the drug
C) Both are the same
D) Neither applies to pharmacology
Correct Answer: B
Rationale: Tolerance develops when repeated exposure to a drug reduces its
effectiveness, often requiring higher doses. Resistance, however, refers to a biological
system’s inherent ability to withstand a drug’s action, such as bacterial resistance to
antibiotics. Differentiating the two guides dosage adjustments and treatment
strategies.
, 5. Abbreviated New Drug Application (ANDA)
A) Full clinical testing of a new drug
B) A process to demonstrate generic bioequivalence without duplicate testing
C) Exclusive to over-the-counter drugs
D) Approval for dietary supplements
Correct Answer: B
Rationale: ANDA allows generic drugs to enter the market by proving they are
bioequivalent to brand-name drugs. This eliminates the need for redundant clinical
trials, speeding approval while maintaining safety and efficacy standards. The FDA
primarily reviews bioavailability studies for ANDAs.

, 6. The Hatch-Waxman Act of 1984 is also known as:
A) The Food, Drug, and Cosmetic Act
B) The Drug Price Competition and Patent Restoration Act
C) The Controlled Substances Act
D) The Orphan Drug Act
Correct Answer: B
Rationale: The Hatch-Waxman Act facilitated the entry of generic drugs into the U.S.
market by allowing FDA approval based on bioequivalence studies instead of repeating
full clinical trials. It also provided brand-name drug manufacturers with patent
protections, including a 30-month stay when ANDA submissions challenged patents.
This law balances innovation with affordable drug access.
7. Four basic transport mechanisms of drugs include:
A) Filtration, osmosis, diffusion, and phagocytosis
B) Passive diffusion, facilitated diffusion, active transport, and pinocytosis
C) Active transport, filtration, osmosis, and conjugation
D) Diffusion, absorption, distribution, and metabolism
Correct Answer: B
Rationale: Drugs move across cell membranes via four primary mechanisms: passive
diffusion (movement along a concentration gradient), facilitated diffusion (carrier-
mediated but not energy-dependent), active transport (energy-dependent, often
against a gradient), and pinocytosis (engulfing fluids and molecules). Understanding
these mechanisms is critical for predicting drug absorption and bioavailability.
8. Potency vs Efficacy:
A) Potency is the maximum effect; efficacy is the dose needed
B) Potency is the amount needed to produce a desired effect; efficacy is the
