1. What is the anion gap in a patient with Na+ 140, Cl- 102, HCO3- 18 mEq/L? → 20 mEq/L
2. A perfusionist notices increasing arterial line pressure with unchanged pump flow. The most appropriate initial response is to: → Check for arterial cannula kinking or obstruction
3. What is the primary ethical obligation of a CCP professional when a conflict of interest arises during oxygenator & pump maintenance activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
4. What is the function of the purge system in a centrifugal ventricular assist device (VAD)? → Flush the motor bearing or pivot with heparinized solution to prevent thrombus formation
5. Which safety checklist step is specifically designed to confirm the correct patient is receiving the correct procedure before initiating cardiopulmonary bypass? → Time-out (Universal Protocol)
6. When protamine is administered to reverse heparin after CPB, which hemodynamic response is most commonly observed? → Transient hypotension
7. Which parameter best reflects the adequacy of systemic oxygen delivery during ECMO support? → Mixed venous oxygen saturation (SvO2)
8. Point-of-care platelet function testing using devices such as the Multiplate analyzer helps guide: → Targeted platelet transfusion decisions in coagulopathic patients
9. Cerebral metabolic rate for oxygen (CMRO2) at 18°C compared to 37°C is approximately: → 10% of normal
10. Which of the following is a fundamental principle of hemodynamic monitoring during bypass as it applies to Certified Clinical Perfusionist? → Systematic evaluation and adherence to established industry standards
11. What safety feature shuts down the pump in case of an emergency? → Emergency stop switch
12. What is the primary ethical obligation of a CCP professional when a conflict of interest arises during neonatal & pediatric perfusion activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
13. Which physiologic parameter is most directly measured by a pulmonary artery catheter to assess right ventricular function? → Pulmonary artery systolic pressure reflecting right ventricular systolic pressure
14. What is the best way to respond to an equipment malfunction during bypass? → Follow safety protocol and report the malfunction
15. Which quality assurance method is most commonly applied in cardioplegia delivery methods to verify that CCP professional standards are being met? → Structured audits, peer reviews, and performance metrics aligned with industry benchmarks
16. Which statement best describes 'del Nido' cardioplegia compared to standard blood cardioplegia? → Del Nido is designed for single-dose myocardial protection lasting up to 90 minutes
17. What is the rationale for recirculating the CPB prime through the circuit for several minutes before initiating bypass? → To remove residual air, mix additives uniformly, and allow the circuit to equilibrate
18. What is the target nasopharyngeal temperature for deep hypothermic circulatory arrest (DHCA) in adults? → 15-18°C
19. Platelet dysfunction after CPB is primarily caused by: → Platelet activation and degranulation from contact with CPB circuit surfaces
20. A perfusionist notices plasma breakthrough (wet gas side) on a hollow-fiber oxygenator 4 hours into a complex case. The BEST immediate action is: → Prepare to change the oxygenator emergently
21. Protamine administration after CPB can cause which of the following serious adverse effects? → Systemic hypotension and pulmonary hypertension
22. During CPB at normothermia, a patient has measured PaO2 of 200 mmHg. Calculated oxygen content (CaO2) depends primarily on: → Hemoglobin concentration and SaO2, with a minor contribution from dissolved O2
23. During retrograde cardioplegia, the coronary sinus perfusion pressure should generally be maintained below: → 50 mmHg
24. The intra-aortic balloon pump (IABP) improves myocardial oxygen supply primarily by: → Augmenting diastolic pressure and thus increasing coronary perfusion pressure
25. The priming volume of a CPB circuit is critically important because it affects: → Hemodilution and the patient's hematocrit during bypass
26. The red blood cell transfusion trigger most commonly recommended by STS/SCA guidelines in stable cardiac surgical patients is hemoglobin below: → 7 g/dL
27. Centrifugal blood pumps generate flow by: → Creating a rotating magnetic field that spins an impeller or cone
28. What is a critical ethical challenge in perfusion practice? → Respecting patient autonomy and informed decisions
29. After LVAD implantation, which parameter set is most critical to monitor for right heart failure? → Central venous pressure (CVP) and pulmonary artery pressures
30. During hypothermic CPB at 28°C, the target mean arterial pressure recommended to ensure adequate cerebral perfusion in most adult patients is: → 50–70 mmHg
