Core Domains
Hemodynamic Monitoring and Interpretation
Cardiac Pharmacology and Titration
Electrocardiogram (ECG) Analysis and Dysrhythmia Management
Acute Coronary Syndrome and Myocardial Infarction Care
Heart Failure Pathophysiology and Nursing Interventions
Valvular Heart Disease and Surgical Recovery
Vascular Emergencies and Assessment
Cardiovascular Ethics and Legal Standards in Critical Care
Introduction
This comprehensive assessment is designed to evaluate the clinical proficiency and
theoretical knowledge of nursing professionals specializing in cardiovascular care.
,The exam covers a wide spectrum of essential competencies, ranging from
foundational cardiac anatomy to complex hemodynamic management and ethical
decision-making. Through a combination of knowledge-based multiple-choice
questions and high-fidelity, scenario-based applications, this tool measures the
candidate's ability to synthesize data and prioritize care in high-acuity environments.
Emphasis is placed on real-world clinical application, evidence-based practice, and
critical thinking skills necessary for ensuring patient safety and optimizing outcomes
in diverse cardiac populations.
SECTION ONE: QUESTIONS 1–100
1. A patient presents with crushing chest pain and ST-segment elevation in leads
II, III, and aVF. Which area of the heart is most likely affected?
A. Anterior wall
B. Lateral wall
C. Inferior wall
D. Septal wall
🟢 C. Inferior wall
,🔴 RATIONALE: ST-segment elevation in leads II, III, and aVF specifically correlates
with the inferior wall of the heart, usually indicating an occlusion in the right coronary
artery.
2. Which laboratory value is the most highly sensitive and specific indicator of
myocardial cellular injury?
A. CK-MB
B. Myoglobin
C. B-type natriuretic peptide (BNP)
D. Troponin I
🟢 D. Troponin I
🔴 RATIONALE: Troponin I is a protein found only in myocardial tissue and is
released during injury, making it the gold standard for diagnosing myocardial
infarction due to its high specificity.
3. A nurse is caring for a patient with heart failure. Which clinical finding is the
most direct indicator of decreased afterload?
A. Decreased systemic vascular resistance (SVR)
B. Increased pulmonary capillary wedge pressure (PCWP)
, C. Decreased central venous pressure (CVP)
D. Increased mean arterial pressure (MAP)
🟢 A. Decreased systemic vascular resistance (SVR)
🔴 RATIONALE: Afterload refers to the resistance the heart must pump against;
systemic vascular resistance (SVR) is the primary clinical measurement of left
ventricular afterload.
4. A patient with atrial fibrillation is prescribed Warfarin. Which lab result must the
nurse monitor to ensure therapeutic dosing?
A. aPTT
B. PT/INR
C. Platelet count
D. D-dimer
🟢 B. PT/INR
🔴 RATIONALE: The International Normalized Ratio (INR), derived from Prothrombin
Time (PT), is the standard used to monitor the effectiveness and safety of Warfarin
therapy.
