Answer to Question 1

ANS: B
When regurgitation occurs, there is a backflow of blood into an adjacent chamber. For example, in mitral regurgitation the mitral leaflets do not close completely. When the ventricles contract, blood escapes back into the atria, causing a murmur, or whooshing sound. The systolic phase begins with ventricular filling and closing of the aortic valve, which is heard as the first heart sound, S1. Orthopnea is an abnormal condition in which a patient uses multiple pillows when reclining to breathe easier or sits leaning forward with arms elevated.

Answer to Question 2

ANS: A
Nasal cannulas deliver oxygen from 1 to 6 L/min. All other devices (simple face mask, non-rebreather mask, and partial non-rebreather mask) are intended for flow rates greater than 6 L/min.
