NR-508 Advanced Pharmacology Final
Exam Test Bank
250+ Multiple Choice Questions with
Answers and Detailed Rationales
This comprehensive test bank covers the key
topics for Chamberlain University's NR-508
Advanced Pharmacology course. Questions are
organized by drug class and body system with
detailed rationales for NCLEX-style and clinical
application questions.
SECTION 1: Pharmacokinetics &
Pharmacodynamics (Questions 1-25)
1. Which phase of pharmacokinetics is defined
as the movement of a drug from the site of
administration into the bloodstream?
,A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: A
Rationale: Absorption is the process by which a
drug moves from its site of administration (oral,
IM, subcut, transdermal) into the systemic
circulation. Distribution is transport to tissues;
metabolism is biotransformation; excretion is
elimination from the body .
2. Bioavailability refers to:
A. The time it takes for a drug to reach peak
concentration
B. The percentage of an administered drug that
reaches systemic circulation unchanged
,C. The volume of distribution of a drug
D. The rate of drug elimination
Answer: B
Rationale: Bioavailability (F) is the fraction of an
administered dose that reaches systemic
circulation unchanged. IV drugs have 100%
bioavailability (F=1). Oral drugs have lower
bioavailability due to first-pass metabolism .
3. The "first-pass effect" refers to:
A. Excretion of a drug in the urine
B. Metabolism of a drug in the liver before it
reaches systemic circulation (oral drugs)
C. Distribution of a drug to fatty tissues
D. Binding of a drug to plasma proteins
Answer: B
Rationale: The first-pass effect occurs when orally
administered drugs are absorbed from the GI
, tract and transported via the portal vein to the
liver, where they may be extensively metabolized
before reaching systemic circulation .
4. A drug with a short half-life (e.g., 2 hours) is
typically administered:
A. Less frequently (once daily)
B. More frequently (every 4-6 hours)
C. Only once
D. Never orally
Answer: B
Rationale: Drugs with short half-lives require
frequent administration to maintain therapeutic
levels. Drugs with long half-lives (e.g., 24+ hours)
can be given once daily .
5. Steady state of a drug is typically achieved
after:
