Section 1: Pharmacokinetics &
Pharmacodynamics (Q1–25)
Q1. Which pharmacokinetic process
describes the movement of a drug from the
site of administration into the bloodstream?
,A. Distribution
B. Metabolism
C. Absorption
D. Excretion
Correct ☑VERIFIED ANSWERS: C
Rationale: Absorption is the process by
which a drug enters the systemic circulation
from its site of administration. Distribution,
metabolism, and excretion follow
absorption.
Q2. What is the primary site of drug
metabolism for most oral medications?
A. Kidney
B. Liver
,C. Lung
D. Small intestine exclusively
Correct ☑VERIFIED ANSWERS: B
Rationale: The liver contains high
concentrations of cytochrome P450
enzymes responsible for Phase I and Phase
II metabolism of the majority of drugs.
Q3. Which term describes the fraction of an
administered drug that reaches the systemic
circulation unchanged?
A. Bioavailability
B. Half-life
C. Clearance
D. Volume of distribution
Correct ☑VERIFIED ANSWERS: A
, Rationale: Bioavailability describes the
extent and rate at which the active drug
moiety enters systemic circulation.
Intravenous administration has 100%
bioavailability.
Q4. A 65-year-old male with cirrhosis is
prescribed a medication that undergoes
extensive first-pass hepatic metabolism. The
nurse practitioner understands that the
bioavailability of this medication will be
significantly affected by which
pharmacokinetic alteration?
A. Decreased absorption from the GI tract
B. Reduced first-pass metabolism leading to
increased bioavailability
C. Enhanced renal elimination
