Answer to Question 1

ANS: B
Servo regulation is commonly used as a safety mechanism to prevent excessive negative pressure on the right atrium in the presence of inadequate volume. This situation can result from hypovolemia, insufficient height of the patient (poor gravity-assisted flow), or a kink in the can-nula or circuit tubing.

Answer to Question 2

ANS: B
Monitor pre- and postoxygenator pressures frequently. Changes will alert clinicians to clots in the oxygenator. Increases in premembrane pressure only = increased resistance within the oxygen-ator. Increases in pre- AND postmembrane pressures = increased resistance AFTER the oxygen-ator.
