Study Guide
Section 1: Pharmacokinetics &
Pharmacodynamics
Core Concepts
Pharmacokinetics = What the body does to the
drug (ADME: Absorption, Distribution,
Metabolism, Excretion)
Pharmacodynamics = What the drug does to
the body (receptor binding, mechanism of
action)
Practice Questions
1. First-pass metabolism refers to:
, • A) Drug excretion by the kidneys
• B) Drug metabolism in the liver before
reaching systemic circulation
• C) Drug binding to plasma proteins
• D) Drug distribution to tissues
Correct ☑VERIFIED ANSWER: B - First-pass
metabolism reduces the bioavailability of orally
administered drugs as they pass through the
liver before entering systemic circulation .
2. Which route of administration bypasses the
first-pass effect?
• A) Oral
• B) Sublingual
• C) Rectal
• D) Enteral
,Correct ☑VERIFIED ANSWER: B - Sublingual
administration allows direct absorption into
systemic circulation, bypassing portal
circulation and hepatic first-pass metabolism .
3. A drug with a half-life of 4 hours is
administered every 4 hours. Approximately
how many half-lives are required to reach
steady-state concentrations?
• A) 1
• B) 2
• C) 4-5
• D) 8
Correct ☑VERIFIED ANSWER: C - Steady-state is
typically achieved after 4-5 half-lives, regardless
of dosing interval .
4. Bioavailability refers to:
, • A) The fraction of drug eliminated
unchanged by the kidneys
• B) The time for drug to reach half its
maximum concentration
• C) The fraction of an administered dose that
reaches systemic circulation
• D) The rate at which a drug binds to its
receptor
Correct ☑VERIFIED ANSWER: C - Bioavailability
measures the extent and rate at which the
active drug enters systemic circulation .
5. A patient with hepatic cirrhosis has reduced
metabolism of a drug that undergoes
extensive first-pass metabolism. The nurse
expects:
• A) Reduced drug bioavailability
• B) Increased drug bioavailability
