1. Which term refers to the study of how a drug produces its
effects on the body?
A. Pharmacokinetics
B. Pharmacodynamics
C. Pharmacognosy
D. Pharmaceutics
Correct Answer: B. Pharmacodynamics
Rationale: Pharmacodynamics describes the biochemical and
physiological effects of drugs and their mechanisms of action.
2. Which process describes how the body absorbs, distributes,
metabolizes, and excretes a drug?
A. Pharmacodynamics
B. Pharmacokinetics
C. Toxicology
D. Pharmacogenomics
Correct Answer: B. Pharmacokinetics
,Rationale: Pharmacokinetics is commonly summarized as what
the body does to the drug, including absorption, distribution,
metabolism, and excretion.
3. Which organ is primarily responsible for drug metabolism?
A. Heart
B. Liver
C. Pancreas
D. Spleen
Correct Answer: B. Liver
Rationale: The liver contains numerous enzymes, particularly
the cytochrome P450 system, that metabolize many
medications.
4. Which organ is the major route for elimination of many
medications?
A. Kidneys
B. Lungs
C. Skin
D. Stomach
Correct Answer: A. Kidneys
Rationale: The kidneys eliminate many drugs and metabolites
through urine. Renal impairment can therefore increase drug
accumulation.
,5. What is the term for the movement of a drug from its
administration site into the bloodstream?
A. Distribution
B. Absorption
C. Excretion
D. Metabolism
Correct Answer: B. Absorption
Rationale: Absorption is the movement of a drug from its
administration site into systemic circulation.
6. Which route generally provides the most rapid systemic
drug effect?
A. Oral
B. Intramuscular
C. Intravenous
D. Subcutaneous
Correct Answer: C. Intravenous
Rationale: Intravenous administration places the medication
directly into the bloodstream, producing essentially immediate
systemic availability.
7. What does bioavailability refer to?
, A. The amount of drug excreted in urine
B. The fraction of administered drug reaching systemic
circulation
C. The speed at which a drug is metabolized
D. The amount of drug bound to protein
Correct Answer: B. The fraction of administered drug reaching
systemic circulation
Rationale: Bioavailability represents the proportion of an
administered dose that reaches systemic circulation in an active
form.
8. Which route is most affected by first-pass metabolism?
A. Intravenous
B. Sublingual
C. Oral
D. Transdermal
Correct Answer: C. Oral
Rationale: Orally administered medications are absorbed
through the gastrointestinal tract and may undergo extensive
hepatic metabolism before reaching systemic circulation.
9. A drug that binds to a receptor and produces a response is
called a(n):
