Answer to Question 1

ANS: B
The c wave occurs at the beginning of atrial diastole and coincides with the period of ventricular systole and is associated with a transient increase in atrial pressure as the pressure in the ventricle increases and forces the closed atrioventricular valves backward into the atrial chamber.

Answer to Question 2

ANS: C
S3 and S4 are not typically heard with a stethoscope, but these sounds can be amplified and rec-orded graphically with a phonocardiogram.
