Questions 1–40
1. Which pharmacokinetic process describes movement of a drug from the administration
site into systemic circulation?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Answer: B. Absorption
Rationale: Absorption is the movement of a drug from its site of administration into the
systemic circulation. Distribution occurs after the drug reaches circulation, while metabolism and
excretion contribute to elimination.
2. Which organ is primarily responsible for hepatic drug metabolism?
,A. Kidney
B. Liver
C. Spleen
D. Pancreas
Answer: B. Liver
Rationale: The liver contains numerous drug-metabolizing enzymes, particularly cytochrome
P450 enzymes. Although metabolism can occur elsewhere, hepatic metabolism is the major route
for many medications.
3. What does a drug's half-life represent?
A. Time required for absorption
B. Time required for peak concentration
C. Time required for plasma concentration to decrease by 50%
D. Time required for complete elimination
Answer: C. Time required for plasma concentration to decrease by 50%
Rationale: Half-life is the time required for the plasma concentration of a drug to fall by
approximately one-half. It helps determine dosing intervals and the time needed to approach
steady state.
4. A drug that binds to a receptor and produces a physiological response is best described
as:
A. Antagonist
B. Agonist
C. Inhibitor
D. Inducer
Answer: B. Agonist
Rationale: An agonist binds to a receptor and activates it, producing a biological response. An
antagonist binds but generally prevents receptor activation.
5. Which route generally provides 100% bioavailability?
A. Oral
B. Subcutaneous
C. Intravenous
D. Intramuscular
Answer: C. Intravenous
,Rationale: Intravenous administration places the drug directly into systemic circulation, so
bioavailability is considered 100%.
6. What is the first-pass effect?
A. Renal elimination before absorption
B. Metabolism of an orally administered drug before it reaches systemic circulation
C. Protein binding in plasma
D. Drug distribution into tissues
Answer: B. Metabolism of an orally administered drug before it reaches systemic
circulation
Rationale: Drugs absorbed from the gastrointestinal tract may pass through the portal circulation
and liver before reaching systemic circulation. Extensive hepatic metabolism can reduce
bioavailability.
7. Which factor can significantly alter medication pharmacokinetics in an older adult?
A. Increased total body water
B. Increased renal clearance
C. Reduced renal function
D. Increased hepatic blood flow
Answer: C. Reduced renal function
Rationale: Aging may reduce renal function, which can decrease clearance of renally eliminated
drugs and increase the risk of accumulation and toxicity.
8. Which term describes the concentration of a drug at which its pharmacologic effect is
observed?
A. Therapeutic concentration
B. Loading concentration
C. Clearance concentration
D. Distribution concentration
Answer: A. Therapeutic concentration
Rationale: The therapeutic concentration is the range associated with desired pharmacologic
effects. Drugs with narrow therapeutic indexes require particularly careful monitoring.
9. A medication with a narrow therapeutic index requires:
A. No laboratory monitoring
B. Less frequent assessment
, C. Careful monitoring for efficacy and toxicity
D. Automatic dose doubling
Answer: C. Careful monitoring for efficacy and toxicity
Rationale: A narrow therapeutic index means the difference between effective and toxic
concentrations is relatively small.
10. Which process describes movement of a drug from the bloodstream into tissues?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: B. Distribution
Rationale: Distribution occurs when medication moves from systemic circulation into body
tissues and fluids.
11. Which patient factor is most likely to increase the risk of drug accumulation?
A. Increased renal clearance
B. Reduced renal clearance
C. Increased fluid intake
D. Increased gastrointestinal motility
Answer: B. Reduced renal clearance
Rationale: Reduced renal clearance prolongs drug elimination and may cause plasma
concentrations to rise with repeated dosing.
12. A medication that binds to albumin is primarily:
A. Freely filtered by the kidney
B. Protein-bound in plasma
C. Immediately excreted
D. Completely absorbed
Answer: B. Protein-bound in plasma
Rationale: Many medications circulate partially bound to plasma proteins. Only the unbound
fraction is generally available to cross membranes and exert pharmacologic effects.
13. Which statement about pharmacodynamics is correct?
A. It describes what the body does to the drug.
B. It describes what the drug does to the body.
