,Question 1 — Easy — MCQ
Which statement best defines pharmacology?
A. The study of how diseases are diagnosed
B. The study of drugs and their interactions with living systems
C. The study of surgical procedures and recovery
D. The study of nutrition and metabolism
Correct Answer:
B. The study of drugs and their interactions with living systems
Rationale:
Pharmacology is the study of drugs and how they interact with living organisms. A focuses on
diagnosis, C on surgery, and D on nutrition rather than drug action.
Question 2 — Easy — MCQ
Which term refers specifically to the use of drugs to prevent, diagnose, or treat disease in
patients?
A. Pharmacodynamics
B. Pharmacogenetics
C. Pharmacotherapy
D. Toxicology
Correct Answer:
C. Pharmacotherapy
Rationale:
Pharmacotherapy refers to the use of medications in patient care to prevent, diagnose, or treat
disease. Pharmacodynamics concerns drug effects and mechanisms, pharmacogenetics concerns
genetic influences on drug response, and toxicology focuses on harmful effects of chemicals and
drugs.
