SECTION I — INTRODUCTION
Questions 1–20
Question 1
Which pharmacokinetic process describes movement of a medication from the gastrointestinal
tract into systemic circulation?
A. Distribution
B. Absorption
,C. Metabolism
D. Excretion
Correct Answer: B. Absorption
Rationale: Absorption is the movement of a drug from its site of administration into the
systemic circulation. Oral medications must first dissolve and cross gastrointestinal membranes
before entering the bloodstream. Distribution occurs after systemic absorption, whereas
metabolism and excretion contribute to elimination.
Question 2
Which pharmacokinetic parameter describes the proportion of an administered drug dose that
reaches systemic circulation unchanged?
A. Half-life
B. Clearance
C. Bioavailability
D. Volume of distribution
Correct Answer: C. Bioavailability
Rationale: Bioavailability represents the fraction of an administered dose that reaches systemic
circulation in active form. Intravenous administration has essentially complete bioavailability,
whereas oral administration may have reduced bioavailability because of incomplete absorption
and first-pass metabolism.
Question 3
A medication with a narrow therapeutic index requires particular attention to which principle?
A. Minimal monitoring is necessary
B. Small changes in concentration may cause toxicity or treatment failure
C. The medication can be given at any dose
D. Therapeutic drug monitoring is never useful
Correct Answer: B. Small changes in concentration may cause toxicity or treatment failure
Rationale: A narrow therapeutic index means that the effective concentration is relatively close
to the toxic concentration. Drugs in this category may require serum-level monitoring, careful
dose adjustment, and assessment for drug interactions.
,Question 4
Which organ is primarily responsible for metabolism of many medications?
A. Liver
B. Spleen
C. Pancreas
D. Thyroid
Correct Answer: A. Liver
Rationale: The liver contains numerous metabolic enzymes, including cytochrome P450
enzymes, that transform many medications into metabolites. Hepatic impairment can therefore
alter drug exposure and may require dose or medication selection adjustments.
Question 5
What is the principal purpose of a loading dose?
A. To permanently increase renal clearance
B. To rapidly achieve a desired therapeutic concentration
C. To eliminate adverse effects
D. To prevent absorption
Correct Answer: B. To rapidly achieve a desired therapeutic concentration
Rationale: A loading dose is used when rapid achievement of therapeutic drug concentrations is
clinically desirable. The appropriate loading dose depends substantially on the medication's
volume of distribution and the target concentration.
Question 6
Which statement best describes pharmacodynamics?
A. What the body does to the drug
B. How the drug is absorbed
C. What the drug does to the body
D. How the kidney eliminates the drug
Correct Answer: C. What the drug does to the body
Rationale: Pharmacodynamics concerns drug effects and mechanisms of action, including
receptor interactions, dose-response relationships, therapeutic effects, and adverse effects.
Pharmacokinetics instead describes absorption, distribution, metabolism, and excretion.
, Question 7
An agonist generally produces its pharmacologic effect by:
A. Blocking every receptor
B. Activating a receptor
C. Increasing renal filtration
D. Preventing drug absorption
Correct Answer: B. Activating a receptor
Rationale: An agonist binds to a receptor and produces a biologic response. A full agonist can
produce maximal receptor-mediated activity, whereas a partial agonist produces a submaximal
response even when receptors are occupied.
Question 8
A competitive antagonist generally:
A. Permanently destroys receptors
B. Competes with an agonist for receptor binding
C. Always produces the same effect as an agonist
D. Increases drug absorption
Correct Answer: B. Competes with an agonist for receptor binding
Rationale: Competitive antagonists occupy receptor sites and reduce agonist activity. Depending
on the receptor system, increasing the concentration of agonist may overcome competitive
antagonism.
Question 9
Which patient factor is especially important when determining medication dosing in an older
adult?
A. Hair color
B. Renal function
C. Eye color
D. Hand dominance
Correct Answer: B. Renal function
