ABCP PERFUSION BASIC SCIENCE EXAM
2026 BANK ALL COMPLETE (394) CURRENT
TESTING QUESTIONS AND DETAILED
CORRECT ANSWERS.
ABCP
Prepare for the ABCP Perfusion Basic Science Exam with
this concise study resource covering cardiovascular
physiology, perfusion principles, and core scientific
concepts. It reviews key topics and exam-style questions
to support effective preparation. Designed to strengthen
understanding and improve test readiness. Suitable for
perfusion students and professionals preparing for
perfusion certification exams.
IABP therapy has been suggested to increase coronary blood
flow by:
a. providing the coronaries with an increased filling pressure
during systole
b. providing the coronaries with an increased filling pressure
during diastole
, Page 2 of 176
c. decreasing the workload of the left ventricle
d. decreasing the workload of the right ventricle ✓ ✓ ......
ANSWER ....... b
Improper placement of the IVC cannula (over insertion)
might obstruct with vessel?
a. renal artery
b. hepatic artery
c. hepatic vein
d. femoral vein ✓ ✓ ...... ANSWER ....... c
Choose the correct statement:
a. heparin will lyse some existing clots
b. celite is an activator used for the ACT test
c. it is more desirable to administer blood cardioplegia at 4 C
rather than at 20 C primarily because of the increased
viscosity associated with blood at lower temperatures

d. ischemic injury is synonymous with reperfusion injury ✓
✓ ...... ANSWER ....... b
During bi-caval venous cannulation, what monitoring
parameter indicates cerebral blood flow?
a. systemic pressure
b. central venous pressure
c. perfusion pressure
d. pulmonary artery pressure ✓ ✓ ...... ANSWER ....... c
Which of the following is not a widely accepted criticism of
the intermittent aortic cross clamping technique?
a. normal coronary blood flow is not assured during
reperfusion
b. energy demand is excessive
c. ischemic periods are cumulative, increasing myocardial
infarction potential
d. procedure is technically difficult ✓ ✓ ...... ANSWER .......
d

When titrated heparin and nitroglycerin drips are
discontinued abruptly before CPB, the ACT will:
a. decrease rapidly
b. increase slowly
c. increase rapidly
d. will remain the same ✓ ✓ ...... ANSWER ....... a
Choose the most correct statement:
a. normally, hemoglobin is 27% saturated at a plasma pO2 of
50 mmHg, this is defined as the p50 of blood
b. if the p50 of blood rises, this is an indication of right
shifting of the oxyhemoglobin saturation curve; this means
that oxygen is more tightly bound to the hemoglobin
molecule
c. as the pH of the blood falls, the oxyhemoglobin curve
would shift to the right and the p50 would fall
