SECTION I — INTRODUCTION
Questions 1–20
Question 1
Which pharmacologic principle describes the study of what a drug does to the body?
A. Pharmacokinetics
B. Pharmacodynamics
C. Pharmacogenomics
D. Pharmacotherapeutics
Correct answer: B. Pharmacodynamics
,Rationale: Pharmacodynamics describes the biochemical and physiologic effects of medications
and their mechanisms of action. Pharmacokinetics instead concerns absorption, distribution,
metabolism, and excretion.
Question 2
Which process describes movement of a medication from the administration site into systemic
circulation?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct answer: A. Absorption
Rationale: Absorption is the movement of a drug into the bloodstream. The route of
administration can substantially affect the rate and extent of absorption.
Question 3
Which organ is primarily responsible for metabolism of many medications?
A. Heart
B. Liver
C. Spleen
D. Pancreas
Correct answer: B. Liver
Rationale: Hepatic enzymes, particularly cytochrome P450 enzymes, metabolize many drugs.
Liver dysfunction can therefore alter drug concentrations and increase toxicity risk.
Question 4
Which term describes the amount of unchanged medication that reaches systemic circulation?
A. Clearance
B. Half-life
C. Bioavailability
D. Potency
Correct answer: C. Bioavailability
,Rationale: Bioavailability represents the fraction of an administered drug that reaches systemic
circulation in an active form. Intravenous administration generally has 100% bioavailability.
Question 5
A medication's half-life is best defined as the time required for:
A. Complete elimination
B. Peak concentration to occur
C. Plasma concentration to decrease by 50%
D. Absorption to begin
Correct answer: C. Plasma concentration to decrease by 50%
Rationale: Half-life is the time required for the concentration of a drug in plasma to fall by
approximately one-half. It helps determine dosing intervals and time to steady state.
Question 6
Which patient factor is particularly important when prescribing medications primarily eliminated
by the kidneys?
A. Hair color
B. Renal function
C. Height alone
D. Eye color
Correct answer: B. Renal function
Rationale: Reduced renal function can decrease drug clearance and cause accumulation. Kidney
function should therefore be considered when dosing renally eliminated medications.
Question 7
A drug that binds to a receptor and produces a physiologic response is called a:
A. Receptor antagonist
B. Receptor agonist
C. Metabolite
D. Chelator
Correct answer: B. Receptor agonist
, Rationale: An agonist activates a receptor and produces a biologic response. An antagonist binds
to a receptor but blocks or reduces receptor activation.
Question 8
What is the primary purpose of therapeutic drug monitoring?
A. To eliminate all adverse effects
B. To measure medication adherence only
C. To maintain drug concentrations within an appropriate therapeutic range
D. To determine the patient's blood type
Correct answer: C. To maintain drug concentrations within an appropriate therapeutic
range
Rationale: Therapeutic drug monitoring is useful for medications with narrow therapeutic
windows or substantial variability in pharmacokinetics.
Question 9
Which medication-related event should generally be reported immediately when it involves
airway compromise?
A. Mild thirst
B. Anaphylaxis
C. Mild fatigue
D. Temporary unpleasant taste
Correct answer: B. Anaphylaxis
Rationale: Anaphylaxis can rapidly cause airway obstruction, hypotension, and cardiovascular
collapse. It is a medical emergency requiring immediate treatment.
Question 10
Which principle is most appropriate when prescribing an antimicrobial?
A. Treat every infection with an antibiotic
B. Use the narrowest effective therapy when appropriate
C. Continue therapy indefinitely
D. Ignore culture results
Correct answer: B. Use the narrowest effective therapy when appropriate
