Question 1

What is the primary purpose of a one-way valve installed in the left ventricular (LV) vent line of a cardiopulmonary bypass circuit?

To prevent accidental pressurized air or blood from being pumped back into the heart if the roller pump is run backward To increase the negative suction pressure within the left ventricle during high-flow drainage To prevent blood from flowing from the cardiotomy reservoir back into the aortic root during cardioplegia delivery To vent excess air from the venous reservoir directly into the atmosphere

Correct Answer:

To prevent accidental pressurized air or blood from being pumped back into the heart if the roller pump is run backward

Question 2

A patient has an estimated blood volume (EBV) of 5,000 mL and a baseline hematocrit (Hct) of 45%. If the cardiopulmonary bypass circuit is primed with 1,500 mL of crystalloid solution, what is the estimated on-bypass hematocrit after hemodilution, assuming no red blood cells are added?

31.5% 34.6% 29.0% 26.5%

Correct Answer:

34.6%

Question 3

When managing acid-base chemistry using the alpha-stat strategy during hypothermic cardiopulmonary bypass at 30°C, how should the arterial blood gas values be interpreted?

The blood gas values must be corrected to the patient's actual body temperature of 30°C The blood gas values measured at 37°C should be maintained at a pH of 7.40 and a PaCO2 of 40 mmHg Carbon dioxide should be added to the oxygenator sweep gas to keep the pH at 7.40 at 30°C The patient's actual pH at 30°C should be maintained at 7.40 regardless of the 37°C measurement

Correct Answer:

The blood gas values measured at 37°C should be maintained at a pH of 7.40 and a PaCO2 of 40 mmHg

Question 4

Which of the following interventions is the most appropriate first step to resolve a venous air lock that causes a sudden, complete loss of venous return during cardiopulmonary bypass?

Increase the vacuum pressure in the venous reservoir immediately Clamp the arterial line and stop the arterial pump, then clamp the venous line to prevent retrograde air migration Increase the arterial pump speed to pull more volume through the venous line Open the arterial filter vent line and flush the system with saline

Correct Answer:

Clamp the arterial line and stop the arterial pump, then clamp the venous line to prevent retrograde air migration

Question 5

A patient on cardiopulmonary bypass has a mean arterial pressure (MAP) of 65 mmHg, a central venous pressure (CVP) of 5 mmHg, and a pump flow rate of 4.8 L/min. What is the patient's systemic vascular resistance (SVR) in dynes·sec·cm^-5?

1,250 dynes·sec·cm^-5 1,000 dynes·sec·cm^-5 800 dynes·sec·cm^-5 1,150 dynes·sec·cm^-5

Correct Answer:

1,000 dynes·sec·cm^-5
