Section I — Introduction and Foundational Pharmacotherapy
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 interacts with a receptor
D. How therapeutic effects are evaluated
Correct answer: B
Rationale: Pharmacokinetics describes the movement of a drug through the body, traditionally
summarized as absorption, distribution, metabolism, and excretion (ADME). Pharmacodynamics
describes the effects of the drug on the body.
Question 2
Which process primarily determines how a medication enters systemic circulation after oral
administration?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Correct answer: B
Rationale: Absorption is the movement of a drug from its administration site into systemic
circulation. Oral drugs must pass through the gastrointestinal tract and intestinal wall before
reaching the systemic circulation.
Question 3
A drug's half-life is best defined as the time required for:
A. The drug to begin producing an effect
B. The drug to reach peak concentration
C. The plasma concentration to decrease by 50%
D. The drug to be completely eliminated
Correct answer: C
Rationale: Half-life is the time required for plasma drug concentration to fall by approximately
50%. It is an important determinant of dosing intervals and time required to approach steady
state.
,Question 4
Which route generally provides the most complete systemic bioavailability?
A. Oral
B. Sublingual
C. Intravenous
D. Rectal
Correct answer: C
Rationale: Intravenous administration places medication directly into systemic circulation and
therefore has essentially 100% bioavailability. Oral administration may have reduced
bioavailability because of incomplete absorption and first-pass metabolism.
Question 5
The term “first-pass effect” refers primarily to:
A. Renal elimination before absorption
B. Hepatic metabolism before a drug reaches systemic circulation
C. Distribution into adipose tissue
D. Drug binding to plasma proteins
Correct answer: B
Rationale: Drugs absorbed from the gastrointestinal tract commonly travel through the portal
circulation to the liver before reaching systemic circulation. Hepatic metabolism during this
initial passage can substantially reduce bioavailability.
Question 6
Which patient factor is most likely to increase the risk of drug accumulation?
A. Increased renal clearance
B. Short drug half-life
C. Reduced renal function
D. Increased hepatic metabolism
Correct answer: C
Rationale: Reduced renal function can decrease elimination of drugs that depend on renal
clearance. If dosing is not adjusted, drug concentrations may increase and produce toxicity.
, Question 7
A medication has a narrow therapeutic index. What does this mean?
A. The drug is ineffective at standard doses
B. There is a relatively small difference between therapeutic and toxic concentrations
C. The medication has no adverse effects
D. The medication is eliminated rapidly
Correct answer: B
Rationale: A narrow therapeutic index means therapeutic and toxic concentrations are relatively
close. Such medications require careful dosing and monitoring.
Question 8
Which laboratory assessment is particularly important when evaluating medication elimination
by the kidneys?
A. Serum creatinine
B. Hemoglobin A1c
C. AST only
D. Platelet count
Correct answer: A
Rationale: Serum creatinine is commonly used as part of an assessment of renal function.
Estimated glomerular filtration rate or creatinine clearance may then be used to guide dosing for
renally eliminated medications.
Question 9
Which pharmacodynamic concept describes the maximum effect a drug can produce?
A. Potency
B. Efficacy
C. Bioavailability
D. Clearance
Correct answer: B
Rationale: Efficacy refers to the maximum therapeutic effect achievable with a drug. Potency
describes the amount of drug required to produce a particular effect.
