NURS 251 Module 9 Final Exam

Structured Practice Questions and
Study Companion
Question 1
The study of drug absorption, distribution, metabolism, and excretion is known as:
A. Pharmacotherapeutics
B. Pharmacodynamics
C. Pharmacokinetics
D. Pharmacy
Correct Answer: C. Pharmacokinetics
Rationale: Pharmacokinetics refers to what the body does to a drug, including
absorption, distribution, metabolism, and excretion. It explains how drug
concentration changes over time in the body. Pharmacodynamics, in contrast,
describes what the drug does to the body, including receptor interactions and
physiological effects. Pharmacotherapeutics focuses on clinical use of drugs for
disease treatment, while pharmacy is the broader profession concerned with
medication preparation and dispensing.
Question 2
A condition in which a drug should not be administered is referred to as:
A. Side effect
B. Adverse effect
C. Drug allergy
D. Contraindication
Correct Answer: D. Contraindication
Rationale: A contraindication is any condition or factor that makes a particular
treatment unsafe or inappropriate for use. Side effects and adverse effects may occur
during therapy but do not necessarily prevent drug administration. Drug allergy refers
to immune-mediated reactions, while contraindication specifically indicates that a
drug must be avoided due to potential harm.

Question 3
An unusual or unexpected drug reaction in an individual is known as:
A. Toxic effect
B. Antagonism
C. Idiosyncrasy
D. Side effect
Correct Answer: C. Idiosyncrasy
Rationale: Idiosyncrasy refers to an abnormal or genetically determined reaction to a
drug that is not predictable from the drug’s pharmacological action. Toxic effects
result from excessive drug levels, while side effects are predictable and often mild.
Antagonism refers to drug interactions that reduce effect.
Question 4
The proprietary name of a drug given by a pharmaceutical company is known as the:
A. Generic name
B. Chemical name
C. Trade name
D. Official name
Correct Answer: C. Trade name
Rationale: The trade name (brand name) is the commercial name assigned by a drug
manufacturer. The generic name is the nonproprietary standard name. The chemical
name describes the drug’s molecular structure.
Question 5
The time from drug administration to the first observable effect is called:
A. Duration of action
B. Onset of action
C. Peak effect
D. Therapeutic range
Correct Answer: B. Onset of action
Rationale: Onset of action is the time it takes for a drug to produce its initial
therapeutic effect after administration. Duration refers to how long the drug effect
lasts, while peak effect is the maximum intensity of response.

Question 6
A drug regulated due to potential abuse and dependence is classified as a:
A. OTC drug
B. Prescription drug
C. Controlled substance
D. Herbal supplement
Correct Answer: C. Controlled substance
Rationale: Controlled substances are drugs regulated by law due to abuse potential
and dependence risk. OTC drugs do not require prescriptions, while prescription
drugs require medical authorization but are not necessarily controlled substances.
Question 7
The study of drug dosage required to produce a therapeutic effect is:
A. Posology
B. Toxicology
C. Pharmacodynamics
D. Pharmacology
Correct Answer: A. Posology
Rationale: Posology deals with drug dosage and administration schedules required to
achieve therapeutic effects safely. Toxicology focuses on harmful effects, while
pharmacodynamics studies drug action mechanisms.
Question 8
A medication that can be purchased without a prescription is called:
A. Generic drug
B. Prescription drug
C. Nonprescription drug
D. Controlled substance
Correct Answer: C. Nonprescription drug
Rationale: Nonprescription drugs (OTC drugs) can be purchased without a
physician’s order. Prescription drugs require authorization due to higher risk or
monitoring needs.
Question 9
, 2026/2027
Which of the following is considered an adverse drug reaction?
A. Idiosyncrasy
B. Drug allergy
C. Teratogenicity
D. All of the above
Correct Answer: D. All of the above
Rationale: Adverse drug reactions include unpredictable or harmful responses such as
allergic reactions, idiosyncratic responses, and teratogenic effects that harm fetal
development.
Question 10
The time during which a drug produces its therapeutic effect is called:
A. Duration of action
B. Onset of action
C. Half-life
D. Absorption phase
Correct Answer: A. Duration of action
Rationale: Duration of action is the total time a drug continues to exert its effect in the
body after administration.
Question 11
The slowest route of drug absorption is:
A. Intravenous
B. Sublingual
C. Intramuscular
D. Transdermal
Correct Answer: D. Transdermal
Rationale: Transdermal absorption is slow because the drug must pass through the
skin barrier. Intravenous administration is immediate.
Question 12
Drugs that cross the blood-brain barrier must be:
A. Water soluble
B. Ionized
