NR-508 Advanced Pharmacology – Prep Exam
Question Bank
150+ Multiple Choice Questions with Answers
and Detailed Rationales
Course Description: NR-508 Advanced Pharmacology is a
core course at Chamberlain University focusing on
pharmacology and therapeutics used in the treatment of
selected health conditions commonly encountered by the
advanced practice nurse in the primary care setting .
Emphasis is placed on the decision-making process
utilized to safely and effectively prescribe and monitor
pharmacotherapeutics for the treatment of acute and
chronic diseases appropriate to the patient situation .
This comprehensive prep exam covers pharmacokinetics,
pharmacodynamics, drug-drug interactions, adverse drug
reactions, antimicrobial stewardship, and system-specific
pharmacotherapy .
Topic 1: Foundational Principles of Pharmacology
(Questions 1-20)
,1. The three most important characteristics of any drug
are:
a) Purity, potency, and safety
b) Effectiveness, safety, and selectivity
c) Selectivity, efficacy, and low cost
d) Safety, potency, and efficacy
Answer: b
Rationale: The three most important characteristics of
any drug are effectiveness (the drug elicits the intended
response), safety (the drug does not produce harmful
effects even at higher doses), and selectivity (the drug
elicits only the intended response without acting on
other receptors) . Potency is less clinically important than
efficacy.
2. The four phases of pharmacokinetics are:
a) Absorption, Action, Metabolism, Tolerance
b) Absorption, Distribution, Metabolism, Excretion
c) Action, Distribution, Excretion, Tolerance
d) Administration, Absorption, Action, Elimination
Answer: b
,Rationale: Pharmacokinetics describes what the body
does to a drug and includes four processes: Absorption
(movement from administration site into bloodstream),
Distribution (movement from blood to tissues),
Metabolism (biotransformation, primarily in the liver),
and Excretion (elimination from the body) . ADME is the
standard mnemonic.
3. The primary site of drug metabolism is the:
a) Kidney
b) Liver
c) Small intestine
d) Lungs
Answer: b
Rationale: The liver is the primary site of drug
metabolism. Phase I reactions (oxidation, reduction,
hydrolysis) and Phase II reactions (conjugation) convert
lipid-soluble drugs into more water-soluble compounds
for excretion. The kidneys are the primary site of drug
excretion .
4. A drug with a narrow therapeutic index:
a) Has a wide margin of safety
, b) Requires therapeutic drug monitoring
c) Is always given intravenously
d) Cannot be used in elderly patients
Answer: b
Rationale: Drugs with a narrow therapeutic index (e.g.,
warfarin, phenytoin, lithium, digoxin) have a small margin
of safety between therapeutic and toxic doses. They
require therapeutic drug monitoring to maintain levels
within the therapeutic range and prevent toxicity .
5. Steady state of a drug is achieved after
approximately:
a) One half-life
b) Two half-lives
c) Four to five half-lives
d) Eight half-lives
Answer: c
Rationale: Steady state is achieved when drug
accumulation and elimination are in equilibrium, typically
after four to five half-lives. At this point, the amount of
drug entering the body equals the amount being
eliminated .
