NUR 210 EXAM 1, 2, 3, AND 4 – GALEN
PHARMACOLOGY REVIEW 2026 EXAM
QUESTIONS AND CORRECT ANSWERS

Introduction
The NUR 210 Pharmacology Review covering Exams 1–4 is designed to help nursing students
strengthen their understanding of medication principles, drug classifications, therapeutic effects,
adverse reactions, contraindications, and safe medication administration. Pharmacology is
essential to nursing practice because medication errors can cause serious harm, while accurate
medication knowledge supports effective treatment, patient education, and clinical decision-
making.
This practice question bank is intended for students preparing for pharmacology assessments in a
nursing program, including students reviewing material associated with Galen College of
Nursing. It uses challenging, scenario-based multiple-choice questions to help learners apply
concepts rather than simply memorize definitions. Each question has four answer options, one
best answer, and a detailed rationale explaining the correct choice and why the alternatives are
less appropriate.
The questions cover common foundational pharmacology topics, including pharmacokinetics,
pharmacodynamics, medication calculations, autonomic drugs, cardiovascular medications, anti-
infectives, endocrine therapies, pain management, and medication safety. Use the bank to
identify knowledge gaps, revisit difficult concepts, and practice clinical reasoning before your
assessment. These are original study questions, not official Galen examination items; the exact
course blueprint and exam content may differ.

QUESTIONS 1–100
Pharmacology foundations
Q1: A patient with chronic kidney disease is prescribed a medication that is primarily eliminated
unchanged by the kidneys. After several doses, the patient develops confusion and muscle
twitching. Which pharmacokinetic change most likely contributed to these findings?
A) Increased hepatic first-pass metabolism
B) Reduced renal clearance causing drug accumulation
C) Increased gastrointestinal absorption
D) Increased plasma protein binding
Rationale: Reduced renal clearance allows the drug to accumulate, potentially producing
toxicity, so B is correct. A is incorrect because increased first-pass metabolism generally reduces
the amount of drug reaching systemic circulation. C is incorrect because absorption does not
explain reduced elimination. D is incorrect because increased protein binding would not be the
expected explanation for accumulation from impaired renal clearance.
Q2: A patient receives a drug with a narrow therapeutic index. The prescribed dose has been
unchanged, but the patient begins taking another medication that inhibits the enzyme responsible
for metabolizing the first drug. What is the nurse's priority concern?
A) Reduced therapeutic effect
B) Faster elimination of the original drug
, 3|Page
C) Increased serum concentration and potential toxicity
D) Complete prevention of drug absorption
Rationale: Enzyme inhibition can reduce metabolism and increase the concentration of the
original drug, making toxicity more likely. A and B describe effects more consistent with
increased metabolism. D is incorrect because enzyme inhibition does not automatically prevent
gastrointestinal absorption.
Q3: A patient asks why a loading dose is prescribed before a maintenance regimen. Which
explanation is most accurate?
A) It prevents all adverse drug reactions
B) It helps achieve a therapeutic drug concentration more rapidly
C) It guarantees the drug will be eliminated within one half-life
D) It reduces the medication's bioavailability
Rationale: A loading dose rapidly raises drug concentration toward the target therapeutic level. A
is incorrect because no dosing strategy eliminates all adverse effects. C is incorrect because half-
life describes the rate of concentration decline, not a guarantee of complete elimination. D is
incorrect because a loading dose is intended to establish drug concentration, not reduce
bioavailability.
Q4: A medication has a half-life of 8 hours. Its concentration is initially 80 mg/L. Assuming
first-order elimination, approximately what concentration remains after 24 hours?
A) 40 mg/L
B) 20 mg/L
C) 10 mg/L
D) 5 mg/L
Rationale: Twenty-four hours represents three half-lives: 80 → 40 → 20 → 10 mg/L. A
represents one half-life, B represents two, and D represents four half-lives.
Q5: A patient taking warfarin begins using an over-the-counter product that increases bleeding
risk. Which nursing action is most appropriate?
A) Tell the patient to double the warfarin dose
B) Advise the patient to discontinue warfarin immediately without consultation
