Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: For cardiac patients, ECLS criteria remain subjective. Most cardiac ECLS is performed in the postoperative period, when the patient cannot be weaned from cardiopulmonary bypass, or when assistance is needed for poor ventricular performance. Patients with severe myocarditis may be supported with ECLS until the condition resolves or until transplantation is possible.
D. Incorrect response: See explanation C.

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Venoarterial bypass ECLS is near complete cardiopulmonary bypass that supports both cardiac and pulmonary functions.
