NCLEX-RN Pharmacology Q&A
Mastery: 2025-2026 Edition
This comprehensive Q&A course is designed for nursing students preparing
for the NCLEX-RN exam. It provides a focused, high-volume review of the
most critical pharmacology concepts and medications, complete with
detailed rationales and test-taking strategies. The course is structured to
align with the latest NCLEX-RN test plan and client needs categories.
Module 1: Foundational Pharmacology Concepts
1. A nurse is preparing to administer medication. The nurse
understands that the term "onset of action" refers to the time it
takes for the drug to:
A. Reach its maximum therapeutic effect.
B. Be completely eliminated from the body.
C. Begin to produce a therapeutic response.
D. Be absorbed into the bloodstream.
2. The nurse administers an oral medication. The nurse understands
that the drug’s first-pass effect refers to what?
A. The extensive metabolism of the medication in the liver before it
reaches systemic circulation.
B. The medication's journey through the circulatory system.
C. How the medication is absorbed and distributed throughout the
body.
D. The drug's therapeutic effect after the first dose.
, 3. A patient is prescribed a new medication. The nurse understands
that the therapeutic index of a drug indicates:
A. The lowest dose that will produce a therapeutic effect.
B. The ratio between the toxic dose and the therapeutic dose.
C. The concentration of the drug at which it is 50% eliminated.
D. The time it takes for the drug to reach its maximum concentration.
4. The nurse is caring for a patient with liver failure. The nurse
should be most concerned about the patient's ability to:
A. Absorb medications.
B. Distribute medications.
C. Metabolize medications.
D. Excrete medications.
5. A nurse is reviewing a patient's medication list. The nurse is
aware that a drug with a short half-life will need to be administered:
A. Less frequently to maintain a steady state.
B. More frequently to maintain a steady state.
C. In a higher dose to be effective.
D. Only once daily to prevent toxicity.
6. A patient is taking two medications that are protein-bound. The
nurse should monitor the patient for an increased risk of toxicity
from one of the drugs due to:
A. Increased drug absorption.
