,Question 1 — Easy — MCQ
Which statement best describes pharmacology?
A. The study of how diseases develop in the body
B. The study of drugs and their effects on living organisms
C. The study of surgical treatment methods
D. The study of laboratory techniques used to diagnose disease
Correct Answer:
B. The study of drugs and their effects on living organisms
Rationale:
Pharmacology is the study of drugs and their interactions with
living organisms. The other options describe areas of pathology,
surgery, or diagnostic science rather than pharmacology.
Question 2 — Easy — MCQ
A nurse explains that a drug is being administered to
produce a desired change in the patient's condition. Which
term best describes this use of a drug to prevent, diagnose,
or treat disease?
A. Pharmacokinetics
B. Therapeutics
C. Toxicology
D. Pharmacodynamics
Correct Answer:
B. Therapeutics
Rationale:
Therapeutics concerns the use of drugs and other measures to
prevent, diagnose, or treat disease. Pharmacokinetics describes
drug movement through the body, while pharmacodynamics
, concerns drug effects on the body. Toxicology focuses on harmful
effects of substances.
Question 3 — Easy — MCQ
Which characteristic is most important for an ideal drug?
A. Produces effects that vary widely among patients
B. Produces the desired effect without causing unacceptable
harm
C. Produces several unrelated physiologic effects
D. Remains permanently active in the body
Correct Answer:
B. Produces the desired effect without causing unacceptable
harm
Rationale:
An ideal drug would provide the intended therapeutic effect while
minimizing harmful effects. Wide variability, unnecessary effects,
and prolonged irreversible activity would make drug therapy less
predictable and less safe.
Question 4 — Easy — MCQ
The nurse understands the therapeutic objective of drug
therapy as which of the following?
A. Eliminate every physiologic effect of the drug
B. Produce the desired therapeutic effect while minimizing
adverse effects
C. Maintain the highest possible drug concentration
D. Ensure that all patients receive the same response
