The Kaplan NGN Assessment D is a comprehensive pharmacology integrated examination designed to evaluate nursing students' readiness for
clinical medication management and the Next Generation NCLEX (NGN) exam. This assessment tests critical knowledge across multiple
pharmacotherapy domains, including pharmacokinetics, pharmacodynamics, medication safety, and high-alert drug management. The multiple-
choice and scenario-based structure emphasizes real-world application, requiring candidates to demonstrate clinical judgment, prioritize patient
care using ABC/Maslow frameworks, and make defensible decision-making choices in complex clinical situations. Success on this exam indicates
proficiency in dosage calculations, recognition of adverse drug reactions, understanding of regulatory compliance, and application of professional
nursing standards when administering medications. The assessment prepares candidates for the NGN's focus on clinical judgment measured
through the Clinical Judgment Measurement Model (CJMM).
,Section One: Questions 1–100
Question 1
A nurse is administering warfarin to a patient with a history of deep vein thrombosis. The patient's latest PT/INR result is 4.5. What is the most
appropriate action?
A. Administer the medication as scheduled
B. Hold the medication and notify the provider
C. Administer half the dose and monitor closely
D. Give the medication with vitamin K supplementation
🟢 Correct answer: B
🔴 RATIONALE: A normal INR for warfarin therapy is typically 2.0–3.0 (or 2.5–3.5 for high-risk DVT). An INR of 4.5 indicates excessive
anticoagulation and increased bleeding risk. The nurse must hold the medication and notify the provider immediately to prevent hemorrhage.
Question 2
Which medication requires monitoring of serum potassium levels due to the risk of hyperkalemia?
A. Furosemide
B. Lisinopril
C. Hydrochlorothiazide
D. Spironolactone
🟢 Correct answer: D
,🔴 RATIONALE: Spironolactone is a potassium-sparing diuretic (aldosterone antagonist) that can cause hyperkalemia. Furosemide and
hydrochlorothiazide cause hypokalemia. Lisinopril (ACE inhibitor) can also cause hyperkalemia but spironolactone is the most direct answer for
potassium-sparing class.
Question 3
A patient receiving Vancomycin develops flushing of the face and upper chest with tachycardia. What is the most likely complication?
A. Red Man Syndrome
B. Stevens-Johnson Syndrome
C. Serotonin Syndrome
D. Neurotoxicity
🟢 Correct answer: A
🔴 RATIONALE: Red Man Syndrome is a characteristic adverse reaction to Vancomycin caused by rapid infusion, presenting with flushing of the
face/upper chest, tachycardia, and hypotension. Slowing the infusion rate typically resolves symptoms.
Question 4
Which drug class is associated with the risk of QT prolongation and torsades de pointes?
A. Beta-blockers
B. Fluoroquinolones
C. ACE inhibitors
D. Calcium channel blockers
🟢 Correct answer: B
, 🔴 RATIONALE: Fluoroquinolones (e.g., ciprofloxacin, levofloxacin) are known to cause QT interval prolongation, which can lead to torsades de
pointes, a life-threatening arrhythmia. Beta-blockers, ACE inhibitors, and calcium channel blockers do not typically cause QT prolongation.
Question 5
A patient on methotrexate for rheumatoid arthritis requires monitoring for which adverse effect?
A. Hepatotoxicity
B. Hyperglycemia
C. Hypertension
D. Tachycardia
🟢 Correct answer: A
🔴 RATIONALE: Methotrexate is associated with hepatotoxicity, requiring regular monitoring of liver function tests. It can also cause bone marrow
suppression and mucositis. Hyperglycemia, hypertension, and tachycardia are not primary concerns with methotrexate.
Question 6
What is the primary mechanism of action of beta-blockers in managing hypertension?
A. Inhibition of calcium influx
B. Blockade of sympathetic nervous system activity
C. Vasodilation through prostaglandin release
D. Inhibition of aldosterone
🟢 Correct answer: B
