Cardiac Surgery Certification (CSC) exam
practice test exam
1. Question: What is the primary purpose of cardiopulmonary
bypass during cardiac surgery?
A. To cool the body
B. To provide circulatory and respiratory support
C. To administer medications
D. To monitor vital signs
Answer: B
Rationale: Cardiopulmonary bypass temporarily takes over the
function of the heart and lungs, providing circulatory and
respiratory support during surgery.
2. Question: What is the most common complication following
coronary artery bypass grafting?
A. Infection
B. Atrial fibrillation
C. Renal failure
D. Stroke
Answer: B
,Rationale: Atrial fibrillation is the most common complication
after coronary artery bypass grafting, occurring in 20-40% of
patients.
3. Question: Which medication is used to prevent atrial
fibrillation after cardiac surgery?
A. Beta-blockers
B. Calcium channel blockers
C. Amiodarone
D. All of the above
Answer: D
Rationale: Beta-blockers, calcium channel blockers, and
amiodarone are used for prophylaxis against postoperative
atrial fibrillation.
4. Question: What is the most appropriate intervention for
postoperative atrial fibrillation with hemodynamic instability?
A. Rate control
B. Cardioversion
C. Anticoagulation
D. Observation
Answer: B
,Rationale: Synchronized cardioversion is indicated for atrial
fibrillation with hemodynamic instability.
5. Question: Which finding indicates cardiac tamponade after
cardiac surgery?
A. Hypertension
B. Muffled heart sounds
C. Bradycardia
D. Warm extremities
Answer: B
Rationale: Beck triad of cardiac tamponade includes muffled
heart sounds, hypotension, and jugular venous distension.
6. Question: What is the most appropriate intervention for
cardiac tamponade after cardiac surgery?
A. Pericardiocentesis
B. Chest tube insertion
C. Both A and B
D. Observation
Answer: C
Rationale: Pericardiocentesis and chest tube insertion are used
to manage cardiac tamponade.
, 7. Question: Which finding indicates postoperative bleeding
after cardiac surgery?
A. Chest tube output greater than 100 mL/hour
B. Chest tube output greater than 200 mL/hour
C. Chest tube output greater than 300 mL/hour
D. Chest tube output greater than 400 mL/hour
Answer: B
Rationale: Chest tube output greater than 200 mL/hour for 2-3
hours indicates excessive bleeding and requires immediate
intervention.
8. Question: What is the most appropriate intervention for
excessive postoperative bleeding?
A. Administer protamine
B. Administer blood products
C. Return to surgery
D. All of the above
Answer: D
Rationale: Managing excessive bleeding includes protamine,
blood products, and possible surgical re-exploration.
