INTRODUCTION
The HESI Cardiovascular Examination is a high-stakes, standardized assessment administered
by Elsevier that evaluates the clinical judgment, nursing knowledge, and critical reasoning
abilities of nursing students preparing for licensure. This comprehensive exam is a critical
component of the HESI (Health Education Systems, Inc.) suite and is designed to measure a
student's readiness to practice safely and effectively in cardiovascular nursing. The exam is
utilized by nursing programs nationwide as a predictor of NCLEX success and as a gatekeeper
for progression to advanced clinical courses. The format consists of challenging, scenario-
based multiple-choice questions that require the application of nursing knowledge,
prioritization skills, and clinical decision-making, not just factual recall.
This question bank has been meticulously crafted to mirror the complexity and rigor of the
actual HESI Cardiovascular Exam. It transcends basic definitional questions, presenting you
with realistic clinical scenarios that demand critical thinking, prioritization using frameworks
like ABC and Maslow's hierarchy, and the synthesis of multiple assessment principles. By
working through these 200 advanced questions, you will not only solidify your
understanding of core concepts but also cultivate the clinical reasoning abilities essential for
passing on your first attempt. Each question is accompanied by a detailed rationale that
explains why the correct answer is correct and why the other three options are incorrect,
reinforcing sound clinical judgment. This is your definitive resource for mastering the HESI
Cardiovascular Exam and launching a successful nursing career.
CORE DOMAINS TESTED
1. Cardiovascular Anatomy, Physiology & Assessment: This domain covers the
foundational knowledge required for cardiovascular nursing practice. It includes the
structure and function of the heart, coronary circulation, the cardiac cycle, cardiac
output, and the conduction system. It also includes comprehensive cardiovascular
assessment, including heart sounds, landmarks for auscultation, pulse assessment,
blood pressure measurement, jugular venous distension (JVD), edema, and breath
sounds.
2. Acute Coronary Syndromes (ACS) & Myocardial Infarction: This section assesses the
ability to recognize and manage acute coronary syndromes, including unstable
angina, NSTEMI, and STEMI. It includes the interpretation of 12-lead ECG findings,
,2
cardiac biomarkers (troponin, CK-MB), and the prioritization of evidence-based
interventions including the MONA protocol, reperfusion therapy (PCI, thrombolytics),
and door-to-balloon time constraints.
3. Heart Failure & Cardiomyopathy: This domain focuses on the pathophysiology and
nursing management of heart failure. It includes the differentiation of left-sided vs.
right-sided heart failure, assessment of fluid volume overload (crackles, JVD, edema,
weight gain), acute decompensated heart failure (ADHF) management, and
pharmacological interventions (diuretics, ACE inhibitors, beta-blockers, digoxin).
4. Cardiac Arrhythmias & Conduction Disorders: This section covers the recognition
and management of cardiac dysrhythmias. It includes atrial fibrillation, ventricular
tachycardia, ventricular fibrillation, bradycardia, heart blocks, and the interpretation
of ECG strips. It also includes the nursing responsibilities for cardioversion,
defibrillation, pacemakers, and antiarrhythmic medications.
5. Vascular Disorders & Peripheral Vascular Disease: This domain tests knowledge of
arterial and venous disorders. It includes peripheral artery disease (PAD), peripheral
venous disease (PVD), deep vein thrombosis (DVT), pulmonary embolism (PE), aortic
aneurysm, and vascular complications post-catheterization.
6. Cardiovascular Medications & Pharmacological Management: This section assesses
the nursing responsibilities related to cardiovascular medications. It includes
anticoagulants (heparin, warfarin), antiplatelets, statins, antihypertensives, diuretics,
digoxin, nitrates, and the monitoring of therapeutic ranges, adverse effects, and
reversal agents.
7. Clinical Judgment, Prioritization & Safety: This final domain focuses on the
application of clinical judgment frameworks (ABC, Maslow's hierarchy, nursing
process) to prioritize care for cardiovascular clients. It includes the recognition of
complications (cardiac tamponade, HIT, embolic stroke), emergency management,
and the delegation of care to appropriate personnel.

QUESTIONS 1-200
Q1: A client with acute decompensated heart failure has bilateral
crackles to the apices, SpO₂ 86% on room air, and RR 32. Which
action should the nurse take FIRST?
A) Administer IV furosemide as prescribed
B) Apply high-flow oxygen via non-rebreather mask
C) Insert a Foley catheter for strict output monitoring
D) Obtain a 12-lead ECG
Rationale: The correct answer is B. Using the ABC priority framework,
the client has severe hypoxemia (SpO₂ 86%) indicating impaired gas
exchange. Oxygenation must be restored before addressing fluid
overload with diuretics or monitoring interventions. Option A
addresses fluid overload but is secondary to oxygenation. Option C is
a monitoring intervention, not a priority over airway and breathing.
Option D is diagnostic and can wait until oxygenation is addressed.
Q2: A client receiving continuous IV heparin has an aPTT of 110
seconds (control 30 seconds) and blood-tinged urine. Which action
should the nurse take FIRST?
A) Increase the heparin infusion rate
B) Hold the infusion and notify the provider
C) Administer vitamin K IV push
D) Document findings and reassess in 4 hours
Rationale: The correct answer is B. An aPTT greater than 2.5-3 times
the control indicates excessive anticoagulation with active bleeding.
The infusion must be stopped immediately, and protamine sulfate
may be ordered as the reversal agent. Option A would worsen the
, 4
bleeding. Option C is incorrect; vitamin K reverses warfarin, not
heparin. Option D is unsafe; immediate intervention is required.
Q3: A client with severe aortic stenosis reports episodes of fainting
when standing. The nurse recognizes this symptom as indicating:
A) Mild disease requiring routine follow-up
B) Critical stenosis requiring urgent intervention
C) A benign vasovagal response
D) Adequate compensation of the stenosis
Rationale: The correct answer is B. Exertional or positional syncope in
aortic stenosis indicates fixed cardiac output that cannot meet
cerebral perfusion demands. This is a classic symptom of critical
stenosis requiring valve replacement evaluation. Option A is incorrect;
syncope indicates severe disease. Option C is incorrect; this is not a
benign finding. Option D is incorrect; syncope indicates
decompensation, not compensation.
Q4: A client on a continuous heparin infusion develops a platelet
count drop from 250,000 to 85,000/mm³. Which complication should
the nurse suspect?
A) Heparin-induced thrombocytopenia (HIT)
B) Vitamin K deficiency
C) Disseminated intravascular coagulation
D) Aplastic anemia
Rationale: The correct answer is A. HIT is an immune-mediated
reaction causing platelet activation and destruction. The hallmark is a
>50% drop in platelets, paradoxically increasing thrombosis risk. All
heparin must be stopped immediately. Option B is unrelated to
heparin. Option C presents with different coagulation abnormalities.
Option D affects all cell lines.
