,Introduction
This document presents 100 original verified questions for the NUR 353 Nursing Pharmacology
Exam 4 Comprehensive Examination 2026/2027 | Verified Questions prepared for the
2026/2027 academic year. The content is organized into 4 core domains of equal weight:
Hematologic, Immunologic, and Oncology Pharmacology (25 questions); Endocrine, Metabolic,
and Gastrointestinal Pharmacology (25 questions); Musculoskeletal, Dermatologic, and Sensory
Pharmacology (25 questions); and Complex Multisystem Disorders and Pharmacologic Safety (25
questions). Each question is designed to reinforce the official NUR 353 Examination 4 objectives,
build pharmacologic clinical reasoning, and strengthen readiness for the actual exam and safe
medication administration. The rationales apply foundational nursing textbook methodology,
including NUR 353 course materials, Lehne's Pharmacology for Nursing Care, and Karch's Focus
on Nursing Pharmacology, so that each response is supported by current evidence-based clinical
care guidelines and drug safety standards. The correct responses are evenly distributed across the
four options, and the answer key provides a one-to-one match for every question.
Actual Questions
The 100 verified questions follow, grouped by domain. Read each item, select the single best
option, and compare your selection with the correct response and rationale provided.
Domain 1: Hematologic, Immunologic, and Oncology Pharmacology
Question 1. Which medication is the antidote for heparin toxicity?
A. Protamine sulfate
B. Vitamin K
C. Atropine
D. Naloxone
Correct Answer: A
Rationale: Protamine sulfate binds heparin and neutralizes its anticoagulant effect.
Vitamin K reverses warfarin, atropine treats bradycardia and cholinergic toxicity, and
naloxone reverses opioids.
Question 2. Which medication is the antidote for warfarin toxicity?
A. Protamine sulfate
B. Acetylcysteine
C. Flumazenil
D. Vitamin K
Correct Answer: D
Rationale: Vitamin K restores clotting factors that warfarin inhibits, reversing its
anticoagulant effect. Protamine reverses heparin, acetylcysteine reverses acetaminophen,
and flumazenil reverses benzodiazepines.
Question 3. A client on a heparin infusion has an activated partial thromboplastin
time of 110 seconds with a control of 30 seconds. Which action should the nurse
take?
A. Continue the heparin at the same rate
B. Increase the infusion rate
C. Hold the heparin and notify the provider
D. Administer vitamin K intravenously
Correct Answer: C
Rationale: The therapeutic range is about one and a half to two and a half times the
control, so 110 seconds is supratherapeutic and risks bleeding. Holding the infusion and
notifying the provider is the safe response; vitamin K reverses warfarin, not heparin.

, Question 4. The target international normalized ratio for a client on warfarin with
atrial fibrilation is approximately:
A. 1.0
B. 2.0 to 3.0
C. 5.0
D. 8.0
Correct Answer: B
Rationale: Atrial fibrilation raises stroke risk from clot formation in the atrium, so
anticoagulation to an international normalized ratio of 2.0 to 3.0 prevents thrombus.
Higher ranges apply to mechanical valves.
Question 5. A client taking warfarin should be taught to maintain a consistent
intake of which nutrient?
A. Sodium
B. Calcium
C. Vitamin C
D. Vitamin K
Correct Answer: D
Rationale: Warfarin antagonizes vitamin K-dependent clotting factors, so a steady intake
of vitamin K-rich foods keeps the international normalized ratio stable. Sudden increases
or decreases swing the level out of range.
Question 6. A client receiving enoxaparin, a low-molecular-weight heparin, should
be taught to:
A. Massage the injection site after administration
B. Administer the injection in the abdomen without aspirating or massaging
C. Take it with food
D. Monitor the daily international normalized ratio
Correct Answer: B
Rationale: Enoxaparin is given subcutaneously in the abdomen, pinching the skin,
without aspirating or massaging to prevent bruising. Routine activated partial
thromboplastin time monitoring is not needed because of its predictable effect.
Question 7. A client taking rivaroxaban, a direct oral anticoagulant, asks about
routine blood monitoring. The nurse explains that:
A. Routine international normalized ratio monitoring is not required, but bleeding
precautions apply
B. Frequent international normalized ratio monitoring is required
C. The medication has no bleeding risk
D. It must be given intravenously
Correct Answer: A
Rationale: Direct oral anticoagulants have predictable effects, so routine international
normalized ratio monitoring is not needed. The client observes bleeding precautions and
reports unusual bleeding; kidney function may be checked periodically.
Question 8. A client taking aspirin for cardiovascular protection asks how it works.
The nurse explains that aspirin:
A. Reversibly inhibits cyclooxygenase to reduce platelet aggregation
B. Increases vitamin K-dependent clotting factors
C. Irreversibly inhibits platelet cyclooxygenase for the life of the platelet
D. Dissolves existing blood clots
Correct Answer: C
