,Question 1 — Easy — Multiple Choice
Which statement best defines a drug in pharmacology?
A. A substance used only to treat disease
B. A chemical that alters biologic processes when introduced into
the body
C. A substance that always produces a beneficial effect
D. A chemical that acts only on abnormal cells
Correct Answer:
B. A chemical that alters biologic processes when introduced into
the body
Rationale:
A drug is a chemical substance that can modify biologic function.
A drug does not have to be used exclusively for treatment, and its
effects are not always beneficial. Drug action is not limited to
abnormal cells.
Question 2 — Easy — Multiple Choice
What is pharmacology primarily concerned with?
A. The structure of human body tissues
B. The study of drugs and their effects on living organisms
C. The diagnosis of infectious diseases
D. The development of surgical procedures

D. Pharmacodynamics is limited to adverse drug reactions.
Correct Answer:
C. Pharmacokinetics describes what the body does to the drug.
Rationale:
Pharmacokinetics involves the movement of drugs through the
body, including absorption, distribution, metabolism, and
excretion. Pharmacodynamics concerns what the drug does to
the body, including its physiologic and biochemical effects.
Pharmacodynamics is not limited to adverse reactions.
Question 4 — Easy — Multiple Choice
Which characteristic would be most consistent with an ideal

A. Produces multiple unpredictable effects
B. Has a high risk of serious toxicity
C. Produces the desired effect with minimal unwanted effects
