Question 1
A drug is administered orally and reaches the systemic circulation after
being absorbed from the gastrointestinal tract and undergoing some
metabolism in the liver. Which pharmacokinetic process most directly
explains the fraction of the administered dose that reaches the systemic
circulation unchanged?
A. Clearance
B. Bioavailability
, C. Volume of distribution
D. Half-life
Correct Answer:
B. Bioavailability
Rationale:
Bioavailability is the fraction of an administered dose that reaches the
systemic circulation in unchanged form. For an orally administered
drug, incomplete absorption and first-pass metabolism can reduce
bioavailability.
• A. Clearance: Clearance describes the volume of plasma from
which a drug is completely removed per unit time; it does not
describe the fraction reaching systemic circulation.
• C. Volume of distribution: This reflects the apparent extent of
drug distribution into tissues relative to plasma.
• D. Half-life: Half-life is the time required for the plasma
concentration of a drug to decrease by 50% during the relevant
elimination phase.
Question 2
A patient receives the same drug orally and intravenously at equivalent
doses. The intravenous dose produces a substantially higher systemic
drug exposure. Which explanation is most appropriate?
A. Intravenous administration increases renal excretion
B. Intravenous administration bypasses gastrointestinal absorption and
first-pass metabolism
