AACN identifies CSC as a subspecialty certification for nurses providing direct care to adult cardiac surgery patients in settings such as cardiothoracic surgery, cardiovascular surgery, and post-anesthesia care units. The guide emphasizes **exam-style questions with correct answers and detailed rationales**, helping candidates strengthen clinical judgment and understand the pathophysiology, assessment findings, interventions, and complications associated with adult cardiac surgery. Preparation includes **cardiac surgical procedures**, including coronary artery bypass grafting with and without cardiopulmonary bypass, valve repair and replacement, minimally invasive cardiac procedures, transcatheter valve replacement, Maze procedures, pericardial procedures, and selected thoracic aortic operations. These procedures are included in the current CSC examination framework. The material reinforces **postoperative cardiovascular assessment and hemodynamic management**, including preload, afterload, contractility, cardiac output, systemic vascular resistance, pulmonary pressures, arterial pressure, filling pressures, fluid responsiveness, vasoactive medications, inotropes, and recognition of deteriorating cardiac function. Additional preparation addresses **major postoperative complications**, including cardiogenic shock, hypotension and hypertension, hypovolemia and hypervolemia, postoperative bleeding, myocardial infarction, myocardial stunning, dysrhythmias, right-sided heart failure, cardiac tamponade, pericarditis, vascular complications, and low-cardiac-output states. These complication areas represent a major component of the CSC test plan. The review also covers **respiratory and thoracic complications**, including mechanical ventilation, oxygenation, pulmonary hypertension, atelectasis, pleural complications, pneumothorax, respiratory failure, chest-tube management, pulmonary edema, and assessment of patients requiring prolonged ventilatory support. Questions reinforce **neurologic, renal, gastrointestinal, hematologic, and multisystem complications**, including acute kidney injury, fluid and electrolyte disturbances, neurologic changes, delirium, stroke, anticoagulation-related bleeding, coagulation abnormalities, hepatic or gastrointestinal complications, and the effects of critical illness on multiple organ systems. The pharmacology component addresses **vasopressors, inotropes, antiarrhythmics, anticoagulants, antiplatelet medications, analgesics, sedatives, diuretics, electrolyte replacement, and other medications commonly encountered in cardiac surgical critical care**. Questions emphasize mechanisms, indications, adverse effects, monitoring, and appropriate clinical responses. Preparation further includes **rhythm recognition and management**, including atrial fibrillation, ventricular dysrhythmias, conduction disturbances, heart block, temporary pacing, pacemaker modes, electrolyte-related rhythm abnormalities, and postoperative dysrhythmia management. The resource also reinforces **cardiac surgery-specific monitoring and interventions**, including arterial and central venous monitoring, pulmonary artery catheter data, cardiac output assessment, temporary pacing, chest tubes, mechanical circulatory support, blood-product management, coagulation assessment, and postoperative fluid management. Scenario-based questions encourage candidates to apply clinical judgment to **rapidly changing postoperative patients**, including hypotension, rising filling pressures, decreased cardiac output, excessive chest-tube drainage, new dysrhythmias, acute hypoxemia, tamponade, vasoplegia, bleeding, renal deterioration, and other time-sensitive complications. AACN's 2025 national practice analysis identified **40 task statements and 113 knowledge statements across four content domains** as the basis for the revised CSC examination. AACN states that the updated examination and test plan launch **November 19, 2026**, reflecting current cardiac-surgery nursing practice. This material is designed as a **study and practice resource rather than a reproduction of the actual AACN CSC examination**. Although the title uses “correct verified solutions” and “latest update,” it does not claim to contain leaked, confidential, copyrighted, or identical questions from a live AACN examination, nor does it represent an official AACN answer key.

VERIFIED SOLUTIONS LATEST UPDATE THIS YEAR – JUST
RELEASED
CSC Cardiac Surgery Exam
Exam Coverage
1. Cardiac anatomy, physiology, hemodynamics, and surgical approaches
2. Preoperative assessment and preparation for cardiac surgery
3. Coronary artery disease and coronary artery bypass grafting
4. Cardiopulmonary bypass, myocardial protection, and perfusion principles
5. Aortic and mitral valve surgery
6. Tricuspid, pulmonary, and complex valvular procedures
7. Aortic surgery, dissection, aneurysm, and endovascular principles
8. Congenital cardiac surgery and common surgical repairs
9. Postoperative cardiac critical care, monitoring, and complications

complications
1. Which coronary artery most commonly supplies the anterior wall of the left ventricle

and the anterior portion of the interventricular septum?

A. Right coronary artery

B. Left anterior descending artery

C. Left circumflex artery

D. Posterior descending artery

Correct Answer: B

Rationale: The LAD supplies much of the anterior left ventricular wall, apex, and anterior

two-thirds of the interventricular septum.

, Page 2 of 99


2. Which chamber of the heart normally generates the highest pressure during ventricular

systole?

A. Right atrium

B. Right ventricle

C. Left atrium

D. Left ventricle

Correct Answer: D

Rationale: The left ventricle pumps blood into the systemic circulation and therefore

develops substantially higher systolic pressure than the right ventricle.


3. Which valve separates the left atrium from the left ventricle?

A. Tricuspid valve

B. Pulmonary valve

C. Mitral valve

D. Aortic valve

Correct Answer: C

Rationale: The mitral valve is the atrioventricular valve located between the left atrium

and left ventricle.


4. During cardiac surgery, the right coronary artery is particularly important because it

commonly supplies which conduction structure?

A. Sinoatrial node only

B. Atrioventricular node

C. Left bundle branch exclusively

, Page 3 of 99


D. Purkinje fibers of the left ventricle only

Correct Answer: B

Rationale: In right-dominant circulation, the RCA commonly supplies the AV node

through its nodal branch.


5. Which coronary artery is generally considered the dominant vessel when it gives rise to

the posterior descending artery?

A. Left anterior descending artery

B. Left circumflex artery

C. Right coronary artery

D. Left main coronary artery

Correct Answer: C

Rationale: Most individuals have right-dominant coronary circulation, with the RCA

giving rise to the posterior descending artery.


6. Which structure carries oxygenated blood from the lungs to the left atrium?

A. Pulmonary arteries

B. Superior vena cava

C. Pulmonary veins

D. Coronary sinus

Correct Answer: C

Rationale: The pulmonary veins return oxygenated blood from the lungs to the left

atrium.

7. Which structure is primarily responsible for preventing regurgitation of blood from the

left ventricle into the left atrium during systole?

A. Aortic valve

B. Mitral valve

C. Pulmonary valve

D. Tricuspid valve

Correct Answer: B

Rationale: The mitral valve closes during ventricular systole to prevent backward flow

into the left atrium.


8. What is the primary function of the chordae tendineae during ventricular contraction?

A. Open the aortic valve

B. Prevent atrioventricular valve prolapse

C. Increase coronary perfusion

D. Initiate ventricular depolarization

Correct Answer: B

Rationale: Chordae tendineae and papillary muscles stabilize the atrioventricular valve

leaflets during systole.


9. Which vessel returns deoxygenated blood from the upper body to the right atrium?

A. Inferior vena cava

B. Pulmonary artery

C. Superior vena cava

D. Coronary sinus
