COMPETENCY DOMAINS
• Pharmacokinetics and Pharmacodynamics
• Autonomic Nervous System Pharmacology
• Cardiovascular and Renal Pharmacology

• Respiratory and Gastrointestinal Pharmacology
• Drug Interactions, Adverse Effects, and Nursing Process
INTRODUCTION
This comprehensive examination is designed to assess the knowledge, skills, and competency of
candidates preparing for NR 293 Pharmacology for Nursing Practice Exam 3 at Chamberlain
University. The assessment evaluates essential competencies across core domains through
multiple-choice and scenario-based questions. Candidates must demonstrate critical thinking,
analytical skills, and decision-making abilities required to apply pharmacological knowledge
effectively in professional nursing practice. The exam covers pharmacokinetics,
pharmacodynamics, autonomic nervous system drugs, cardiovascular and renal agents,
endocrine medications, anti-infectives, chemotherapy, CNS drugs, respiratory and GI
medications, and the nursing process related to safe medication administration, monitoring,
and patient education.

1. A nurse is reviewing the pharmacokinetic properties of a new medication. Which
process describes the movement of the drug from the site of administration into the
bloodstream?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
☑ Correct Answer: C
☑ Explanation: Absorption is the movement of a drug from its site of administration
into the systemic circulation. Distribution is the transport of the drug to tissues,
metabolism is biotransformation, and excretion is elimination—none describe the initial
entry into the bloodstream.
2. Which organ is primarily responsible for the first-pass effect of orally administered
drugs?
A. Kidneys
B. Lungs
,3
C. Liver
D. Stomach
☑ Correct Answer: C
☑ Explanation: The first-pass effect occurs in the liver, where orally administered
drugs are metabolized via the portal circulation before reaching systemic circulation.
Kidneys eliminate drugs, lungs have minor metabolic roles, and the stomach is not a
primary site of first-pass metabolism.
3. A nurse is assessing a client for signs of drug toxicity. Which laboratory value would be
most helpful in determining the safety margin of a medication?
A. Therapeutic index
B. Half-life
C. Bioavailability
D. Volume of distribution
☑ Correct Answer: A
☑ Explanation: The therapeutic index is the ratio of toxic dose to therapeutic dose; a
, 4
narrow index indicates a higher risk of toxicity. Half-life, bioavailability, and volume of
distribution describe pharmacokinetic properties but do not directly indicate safety
margin.
4. A client with hepatic cirrhosis is prescribed a medication that undergoes extensive
hepatic metabolism. What should the nurse anticipate?
A. An increased dose may be required.
B. A reduced dose may be required.
C. The drug will have no effect.
D. The drug will be excreted unchanged.
☑ Correct Answer: B
☑ Explanation: Hepatic impairment reduces metabolism, leading to drug
accumulation and increased risk of toxicity; a reduced dose is often necessary. An
increased dose would worsen accumulation. The drug will still have an effect, and it is
not excreted unchanged.
