INTRODUCTION *
*
This comprehensive assessment is designed to evaluate the clinical proficiency and *
critical thinking skills required for the Cardiac Surgery Certification (CSC). The *
exam focuses on the immediate postoperative care of adult cardiac surgical patients *
during the first 48 hours. It assesses knowledge in life-sustaining interventions, *
advanced hemodynamic monitoring, and the management of complex complications. Using *
multiple-choice and scenario-based questions, the assessment emphasizes real-world *
application, patient safety, and evidence-based decision-making. Candidates must *
, demonstrate mastery in surgical pathophysiology and pharmacological management to *
ensure optimal patient outcomes in high-acuity settings. *
SECTION ONE: QUESTIONS 1–100
1. A patient 4 hours post-CABG presents with a sudden drop in chest tube output, muffled heart sounds, and
increased central venous pressure (CVP) equalizing with pulmonary artery wedge pressure (PAWP). What
is the immediate priority?
A. Administration of a 500mL bolus of crystalloid
B. Preparing for emergency re-exploration for cardiac tamponade
C. Increasing the PEEP on the ventilator to improve oxygenation
D. Administering protamine sulfate to reverse residual heparin
🟢 Correct answer: B. Preparing for emergency re-exploration for cardiac tamponade
🔴 RATIONALE: The triad of decreased chest tube output, muffled heart sounds, and equalization of diastolic
pressures (CVP and PAWP) is classic for cardiac tamponade, a surgical emergency requiring immediate
drainage or re-exploration.
2. Which of the following is a primary hemodynamic goal for a patient immediately following a mitral valve
replacement for mitral stenosis?
A. Maintaining a high heart rate to ensure cardiac output
B. Aggressive fluid resuscitation to maintain high filling pressures
C. Maintaining a slow to normal heart rate to allow for ventricular filling
D. Keeping systolic blood pressure above 160 mmHg to ensure organ perfusion
🟢 Correct answer: C. Maintaining a slow to normal heart rate to allow for ventricular filling
, 🔴 RATIONALE: In patients with a history of mitral stenosis, a slower heart rate is vital to maximize diastolic
filling time and prevent pulmonary venous congestion, even after valve replacement.
3. A patient remains on a Nitroprusside infusion at 5 mcg/kg/min for 48 hours. The nurse notes new-onset
confusion, agitation, and metabolic acidosis. Which toxicity should be suspected?
A. Digoxin toxicity
B. Heparin-induced thrombocytopenia
C. Thiocyanate or Cyanide toxicity
D. Protamine reaction
🟢 Correct answer: C. Thiocyanate or Cyanide toxicity
🔴 RATIONALE: Prolonged or high-dose administration of Nitroprusside can lead to the accumulation of
thiocyanate and cyanide, manifesting as CNS changes and unexplained metabolic acidosis.
4. During the first hour post-op, a patient’s chest tube drains 300 mL of bright red blood. The second hour
shows 250 mL. What is the most appropriate nursing action?
A. Milk the chest tubes vigorously every 15 minutes
B. Notify the surgeon and monitor for signs of hypovolemia
C. Place the patient in Trendelenburg position
D. Increase the suction on the chest tube drainage system to -40 cmH2O
🟢 Correct answer: B. Notify the surgeon and monitor for signs of hypovolemia
🔴 RATIONALE: Chest tube drainage exceeding 200 mL/hr for two consecutive hours is a standard threshold
for notifying the surgical team of potential active bleeding.
5. Which laboratory value is most critical to monitor in a patient receiving an Intra-Aortic Balloon Pump
(IABP) to prevent limb-threatening complications?
