INTRODUCTION
,This comprehensive study guide examination is designed to prepare nursing students at Galen College for the NUR
210 Principles of Pharmacology Exam 1. The assessment evaluates foundational knowledge and clinical reasoning
in pharmacology, including pharmacokinetics, pharmacodynamics, drug classifications, adverse effects, medication
safety, and patient education. The examination consists of 100 multiple-choice questions that reflect the style,
complexity, and rigor of the actual course examination. Questions incorporate clinical scenarios, prioritization
challenges, and evidence-based practice principles to strengthen critical thinking and professional decision-making
skills essential for safe medication administration. Successful completion of this practice test indicates readiness for
the official NUR 210 Principles of Pharmacology Exam 1.
SECTION ONE
Questions 1–100
Question 1
A nurse is preparing to administer a medication that is known to have a high first-pass effect. Which of the
following routes of administration would most effectively bypass this effect?
A. Oral
B. Sublingual
,C. Intravenous
D. Intramuscular
🟢 Correct Answer:
B
🔴 RATIONALE:
The first-pass effect refers to the metabolism of a drug by the liver before it reaches systemic circulation.
Sublingual administration allows the drug to be absorbed directly into systemic circulation through the oral
mucosa, bypassing the liver's first-pass metabolism. Oral administration is most affected by first-pass effect.
Intravenous and intramuscular routes also bypass first-pass effect, but the question asks for the route that
bypasses it effectively after oral ingestion.
Question 2
A client is prescribed a medication that is a competitive antagonist. Which of the following best describes the
mechanism of action of this drug?
A. It binds to the receptor and activates a response
B. It binds to the receptor and blocks the agonist from binding
C. It binds to a different receptor site and enhances the agonist's effect
D. It binds to the receptor irreversibly and destroys it
🟢 Correct Answer:
B
, 🔴 RATIONALE:
A competitive antagonist binds to the same receptor site as the agonist but does not activate the receptor,
thereby blocking the agonist from binding and producing a response. Option A describes an agonist. Option C
describes an allosteric modulator. Option D describes an irreversible antagonist.
Question 3
A nurse is reviewing the pharmacokinetics of a medication with a half-life of 6 hours. How long will it take for
the drug to reach a steady state in the client's body?
A. 12 hours
B. 24 hours
C. 30 hours
D. 36 hours
🟢 Correct Answer:
C
🔴 RATIONALE:
A drug reaches steady state after approximately 4 to 5 half-lives. With a half-life of 6 hours, steady state would
be achieved in approximately 24 to 30 hours. Option C (30 hours) is the correct calculation.
