Answer to Question 1

ANS: B
During normal circulation blood is pumped from the right side of the heart to the lungs where O2 and carbon dioxide are exchanged. From the lungs, blood is returned to the left side of the heart. The left heart then pumps oxygenated blood to the major organs and tissues.

Answer to Question 2

ANS: D
The most common form of ECLS is Extracorporeal Membrane Oxygenation (ECMO). There are three general types of ECMO support, venoarterial (VA), venovenous (VV), and emerging arte-riovenous (AV) support.
