,Question 1 — Easy — Multiple Choice
Which term refers to the study of drugs and their effects on
living organisms?
A. Pharmacology
B. Pharmacokinetics
C. Pharmacodynamics
D. Pharmacotherapy
Correct Answer:
A. Pharmacology
Rationale:
Pharmacology is the study of drugs, including their actions and
effects in living organisms. Pharmacokinetics focuses on what the
body does to a drug, while pharmacodynamics focuses on what
the drug does to the body. Pharmacotherapy refers to using drugs
to prevent or treat disease.
Question 2 — Easy — Multiple Choice
A nursing student is reviewing the difference between
pharmacokinetics and pharmacodynamics. Which statement
is correct?
A. Pharmacokinetics describes how drugs produce their effects at
receptor sites.
B. Pharmacodynamics describes how the body absorbs and
eliminates drugs.
C. Pharmacokinetics describes what the body does to a drug.
D. Pharmacodynamics describes how drugs are distributed
through body tissues.
Correct Answer:
C. Pharmacokinetics describes what the body does to a drug.
, Rationale:
Pharmacokinetics concerns absorption, distribution, metabolism,
and excretion—processes describing what the body does to a
drug. Pharmacodynamics concerns drug actions and effects on
the body. Options A, B, and D incorrectly interchange the two
concepts.
Question 3 — Easy — Multiple Choice
Which property best describes an ideal drug?
A. Produces several unrelated physiologic effects
B. Provides the desired therapeutic effect with minimal adverse
effects
C. Requires frequent dosage adjustments in healthy patients
D. Produces the same response regardless of dose
Correct Answer:
B. Provides the desired therapeutic effect with minimal adverse
effects
Rationale:
An ideal drug should produce the desired therapeutic effect while
minimizing undesirable effects. Multiple unrelated effects can
increase adverse reactions, frequent dose adjustments may
reduce convenience and predictability, and drug responses
generally change as dose changes.
Question 4 — Easy — Multiple Choice
What is the primary therapeutic objective of drug therapy?
A. To produce the maximum possible physiologic change
B. To eliminate every symptom regardless of risk
