Introduction
The NUR 210 Principles of Pharmacology review for Exams 1–4 is designed to help nursing
students develop the medication knowledge and clinical judgment needed for safe, effective
nursing practice. Pharmacology assessments commonly evaluate how medications work, how the
body absorbs and eliminates them, when they are indicated, which adverse effects require
intervention, and how nurses monitor patient responses.
This practice question bank is intended for nursing students preparing for pharmacology
examinations, including students reviewing material associated with Galen College of Nursing. It
uses challenging, patient-centered multiple-choice questions with four answer options, one best
answer, and detailed rationales. The scenarios emphasize applying pharmacologic principles to
clinical situations rather than relying on memorization alone.
Topics include medication safety, pharmacokinetics, pharmacodynamics, dosage calculations,
autonomic drugs, cardiovascular medications, anti-infectives, respiratory therapies, endocrine
drugs, gastrointestinal medications, pain management, and patient education. Work through the
questions systematically, explain each answer in your own words, and revisit concepts you miss.
This approach can strengthen clinical reasoning and help identify gaps before an examination.
These are original practice questions for revision, not official Galen exam items; course-specific
coverage and question formats may vary.

QUESTIONS 1–100
Pharmacology principles
Q1: A patient with chronic kidney disease is prescribed a medication eliminated primarily
through the kidneys. After several doses, the patient develops confusion and muscle twitching.
Which explanation is most likely?
A) Increased hepatic metabolism B) Reduced renal clearance causing medication accumulation
C) Increased gastrointestinal absorption D) Reduced medication distribution into tissues
Rationale: B is correct because impaired renal clearance can increase drug concentrations and
cause toxicity. A would generally increase metabolism and may lower exposure. C does not
explain impaired elimination. D is not the primary mechanism suggested by the patient's kidney
disease and developing toxicity.
Q2: A patient taking a narrow-therapeutic-index medication begins a second drug that inhibits
the enzyme responsible for metabolizing the first medication. What is the principal concern?
A) The original drug will always become ineffective B) Renal excretion will immediately double
C) The original drug may accumulate and cause toxicity D) The original drug will no longer be
absorbed
Rationale: C is correct because enzyme inhibition may reduce metabolism and increase drug
exposure. A is not a predictable result. B describes increased renal excretion, which is not
implied by enzyme inhibition. D is incorrect because metabolism and absorption are distinct
processes.
, Q3: A prescriber orders a loading dose followed by maintenance doses. What is the primary
purpose of the loading dose?
A) To eliminate the medication's adverse effects B) To achieve a therapeutic concentration more
rapidly C) To ensure complete drug elimination after one half-life D) To prevent every possible
drug interaction
Rationale: B is correct because a loading dose rapidly establishes the desired drug concentration.
A is incorrect because adverse effects can still occur. C misunderstands half-life, which describes
a reduction in drug concentration rather than complete elimination. D is incorrect because a
loading dose does not prevent interactions.
Q4: A drug has a half-life of 8 hours and an initial concentration of 80 mg/L. Assuming first-
order elimination, what concentration remains after 24 hours?
A) 40 mg/L B) 20 mg/L C) 10 mg/L D) 5 mg/L
Rationale: C is correct. Twenty-four hours represents three half-lives: 80 to 40, 40 to 20, and 20
to 10 mg/L. A represents one half-life, B represents two half-lives, and D represents four half-
lives.
Q5: A patient taking warfarin reports starting an over-the-counter herbal product. What is the
nurse's best response?
A) Tell the patient to double the warfarin dose B) Instruct the patient to permanently discontinue
warfarin C) Identify the product, assess for bleeding, and consult the prescriber or pharmacist
about possible interactions D) Explain that herbal products cannot affect anticoagulation
Rationale: C is correct because some herbal products can alter anticoagulant effects or increase
bleeding risk. A may cause dangerous anticoagulation. B may expose the patient to thrombosis
and is not an appropriate independent instruction. D is incorrect because nonprescription
products can interact with prescribed medications.
Q6: A patient with significantly reduced serum albumin receives a highly protein-bound
medication. Which pharmacologic change may occur?
A) The free drug fraction must decrease B) The free drug fraction may increase, raising the risk
of adverse effects C) The medication will no longer be absorbed D) All of the medication will
immediately become inactive
Rationale: B is correct because lower albumin can increase the unbound fraction of certain
highly protein-bound medications. A describes the opposite effect. C concerns absorption and is
not a direct consequence of low albumin. D is not a plausible consequence of altered protein
binding.
