SECTION I — INTRODUCTION
Questions 1–40
Question 1
Which statement best describes pharmacokinetics?
,A. What a drug does to the body
B. What the body does to a drug
C. How a drug produces an allergic reaction
D. How drugs are prescribed
Correct answer: B
Rationale: Pharmacokinetics describes absorption, distribution, metabolism, and excretion—the
processes by which the body handles a medication. Pharmacodynamics instead concerns the
effects of a drug on the body.
Question 2
Which pharmacokinetic process involves movement of a medication from the administration site
into systemic circulation?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
Correct answer: C
Rationale: Absorption is the movement of a drug from its administration site into the
bloodstream. Intravenous administration bypasses the absorption phase because the medication
enters systemic circulation directly.
Question 3
Which organ is primarily responsible for hepatic drug metabolism?
A. Kidney
B. Liver
C. Spleen
D. Pancreas
Correct answer: B
Rationale: The liver is the principal site of drug metabolism. Hepatic enzymes, particularly the
cytochrome P450 system, transform many medications into metabolites that may be active,
inactive, or toxic.
,Question 4
Which organ is most important for elimination of many medications and their metabolites?
A. Kidney
B. Heart
C. Lung
D. Thyroid
Correct answer: A
Rationale: The kidneys eliminate many drugs through glomerular filtration, tubular secretion,
and reabsorption. Renal impairment can therefore increase drug exposure and toxicity.
Question 5
A medication has a narrow therapeutic index. What does this mean?
A. The medication is absorbed poorly
B. The effective dose is relatively close to the toxic dose
C. The medication cannot be administered orally
D. The drug has no adverse effects
Correct answer: B
Rationale: A narrow therapeutic index indicates a small margin between therapeutic and toxic
concentrations. Such medications generally require careful dosing and monitoring.
Question 6
Which term describes the concentration of a medication required to produce a specified effect?
A. Potency
B. Half-life
C. Clearance
D. Bioavailability
Correct answer: A
Rationale: Potency refers to the amount of drug required to produce a particular effect. A highly
potent drug produces an effect at a lower dose than a less potent drug.
Question 7
, What does efficacy describe?
A. How quickly a drug is absorbed
B. The maximum effect a drug can produce
C. How rapidly the kidneys eliminate a drug
D. The percentage of drug bound to protein
Correct answer: B
Rationale: Efficacy represents the maximum therapeutic effect achievable with a medication. It
differs from potency, which concerns the dose needed to achieve an effect.
Question 8
Which route provides 100% systemic bioavailability?
A. Oral
B. Subcutaneous
C. Intramuscular
D. Intravenous
Correct answer: D
Rationale: Intravenous administration places the drug directly into systemic circulation,
resulting in essentially complete bioavailability.
Question 9
The term “half-life” refers to the time required for:
A. A drug to begin working
B. Half of a drug dose to be absorbed
C. Plasma drug concentration to decrease by 50%
D. A patient to experience an adverse effect
Correct answer: C
Rationale: Drug half-life is the time required for the plasma concentration of a medication to
decline by approximately 50%. It helps determine dosing intervals and time to elimination.
Question 10
