Common complications then were (1) thrombocytopenia, (2) coagulopathy, (3) hemolysis, and (4) renal and pulmonary dysfunction.

Answer to Question 2

ANS: A
A. Correct response: Potential complications of extracorporeal life support, or extracorporeal membrane oxygenation, include clot formation and extensive bleeding caused by systemic anticoagulation and technical failure.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
