EXAM UPDATE 2026/2027.
Core Domains
1. Preoperative Assessment and Risk Stratification
2. Intraoperative Management and Perfusion Technology
3. Postoperative Care and Hemodynamic Monitoring
4. Pharmacology for Cardiac Surgery
5. Surgical Procedures and Indications
6. Complications and Critical Care Management
7. Ethical and Legal Standards in Cardiac Surgery
8. Patient and Family Education and Communication
Introduction
This comprehensive assessment is designed to rigorously evaluate the knowledge and
clinical judgment required for the Barkley CSC Cardiac Surgery Certification. The
examination covers essential domains from preoperative risk stratification to complex
postoperative management. It utilizes a multiple-choice and scenario-based format to
,assess the candidate's ability to apply foundational theory, interpret clinical data, and
make critical decisions in real-world cardiac surgery settings. This practice exam
emphasizes the integration of professional standards, regulatory compliance, and ethical
principles to ensure safe, competent, and patient-centered care.
Section One: Questions 1–100
1. A 68-year-old male with a history of hypertension and diabetes is scheduled for an
elective coronary artery bypass graft (CABG). His preoperative laboratory results
show a serum creatinine of 2.1 mg/dL. Which of the following is the most significant
immediate concern?
A. Increased risk of postoperative mediastinitis
B. Increased risk of acute kidney injury and fluid overload
C. Increased risk of intraoperative arrhythmias
D. Increased risk of stroke from carotid artery stenosis
🟢B
,🔴 RATIONALE: An elevated serum creatinine (above 1.5-2.0 mg/dL) is a strong
indicator of pre-existing renal dysfunction, which is a major risk factor for acute kidney
injury (AKI) following cardiac surgery. This risk is compounded by the use of
cardiopulmonary bypass and potential nephrotoxic agents, leading to fluid overload and
electrolyte imbalances.
2. A patient is weaning from cardiopulmonary bypass (CPB) after a mitral valve
replacement. The arterial waveform shows a narrow pulse pressure and a low
amplitude. The central venous pressure (CVP) is 18 mmHg, and the pulmonary artery
wedge pressure (PAWP) is 22 mmHg. What is the most likely cause?
A. Hypovolemia
B. Left ventricular failure
C. Right ventricular failure
D. Systemic vasodilation
🟢B
🔴 RATIONALE: Elevated PAWP (normally 6-12 mmHg) indicates increased pressure in
the left atrium, which is a hallmark of left ventricular failure or fluid overload. A narrow
, pulse pressure suggests poor left ventricular stroke volume. The elevated CVP is also
consistent with eventual right-sided failure from left-sided failure.
3. Which of the following is the primary mechanism of action for protamine sulfate
when used to reverse heparin after CPB?
A. It potentiates the action of antithrombin III.
B. It directly inhibits thrombin and Factor Xa.
C. It forms a stable, inactive complex with heparin.
D. It promotes the degradation of fibrinogen.
🟢C
🔴 RATIONALE: Protamine sulfate is a highly cationic protein that binds to the anionic
heparin molecule, forming a stable, biologically inactive complex. This neutralizes the
anticoagulant effect of heparin, allowing for the restoration of normal clotting function.
4. According to the Society of Thoracic Surgeons (STS) guidelines, which of the
following is a Class I indication for the use of intra-aortic balloon pump (IABP)
counterpulsation?
