,Question 1 — Easy — MCQ
Which statement best describes pharmacology?
A. The study of how diseases alter body functions
B. The study of drugs and their effects on living organisms
C. The process by which the body eliminates medications
D. The study of surgical treatment methods
Correct Answer:
B. The study of drugs and their effects on living organisms
Rationale:
Pharmacology is the study of drugs, including their actions,
effects, uses, and interactions with living systems. Options A, C,
and D describe narrower concepts rather than pharmacology as a
whole.
Question 2 — Easy — MCQ
A nursing student is reviewing the difference between
pharmacokinetics and pharmacodynamics. Which statement is
correct?
A. Pharmacokinetics describes what the drug does to the body.
B. Pharmacodynamics describes how the body absorbs and

C. Pharmacokinetics describes what the body does to the drug.
D. Pharmacodynamics describes only how rapidly a drug is
eliminated.
Correct Answer:
C. Pharmacokinetics describes what the body does to the drug.
Rationale:
Pharmacokinetics concerns the movement of a drug through the
, body, including absorption, distribution, metabolism, and
excretion. Pharmacodynamics concerns the effects of the drug on
the body.
Question 3 — Easy — MCQ

drug?
A. Produces extensive effects on unrelated tissues
B. Produces the desired effect with minimal toxicity
C. Requires very high doses to produce a response
D. Produces different effects each time it is administered
Correct Answer:
B. Produces the desired effect with minimal toxicity
Rationale:
An ideal drug would produce the intended therapeutic effect
predictably while minimizing unwanted effects. Extensive
unrelated effects, high dosing requirements, and unpredictable
responses are undesirable characteristics.
Question 4 — Easy — MCQ
What is the primary therapeutic objective of drug therapy?

B. To eliminate all physiologic responses to the drug
C. To achieve the desired therapeutic effect with acceptable risk
D. To maintain the drug concentration at the highest possible
