1. What is the primary purpose of pharmacology?
A. To study microorganisms
B. To study drugs and their effects on living organisms
C. To study surgical procedures
D. To study human anatomy
Correct answer: B. To study drugs and their effects on living
organisms
Rationale: Pharmacology is the scientific study of drugs,
including their actions, effects, uses, and interactions within
living organisms.
2. Which term describes the study of how a drug affects the
body?
A. Pharmacokinetics
B. Pharmacodynamics
C. Toxicology
D. Pharmaceutics
,Correct answer: B. Pharmacodynamics
Rationale: Pharmacodynamics examines the biochemical and
physiological effects of drugs and their mechanisms of action.
3. Which process describes how the body absorbs, distributes,
metabolizes, and eliminates a drug?
A. Pharmacodynamics
B. Pharmacokinetics
C. Pharmacogenetics
D. Toxicology
Correct answer: B. Pharmacokinetics
Rationale: Pharmacokinetics describes what the body does to a
drug through absorption, distribution, metabolism, and
excretion.
4. Which route generally provides the most rapid systemic
drug effect?
A. Oral
B. Subcutaneous
C. Intravenous
D. Topical
Correct answer: C. Intravenous
,Rationale: Intravenous administration delivers the drug directly
into the bloodstream, producing rapid systemic availability.
5. What is bioavailability?
A. The amount of drug excreted in urine
B. The fraction of a drug reaching systemic circulation
C. The rate of drug metabolism
D. The strength of a drug's tablet
Correct answer: B. The fraction of a drug reaching systemic
circulation
Rationale: Bioavailability refers to the proportion of an
administered drug that reaches systemic circulation in active
form.
6. Which organ is primarily responsible for drug metabolism?
A. Heart
B. Liver
C. Spleen
D. Pancreas
Correct answer: B. Liver
Rationale: The liver contains enzymes that metabolize many
medications, particularly through the cytochrome P450 system.
, 7. Which organ is most important for elimination of many
drugs?
A. Kidney
B. Stomach
C. Thyroid
D. Gallbladder
Correct answer: A. Kidney
Rationale: The kidneys eliminate many drugs and metabolites
through urine.
8. What is a drug's half-life?
A. Time required for a drug to begin acting
B. Time required for half of the drug to be eliminated
C. Time required for complete absorption
D. Time required for a drug to reach the liver
Correct answer: B. Time required for half of the drug to be
eliminated
Rationale: Half-life is the time required for the plasma
concentration of a drug to decrease by approximately 50%.
9. Which medication response is considered a therapeutic
effect?
