When listening to heart sounds, the nurse hears an S3 sound after S2. What should the nurse suspect is occurring with this patient?
1. ventricular volume overload
2. increased resistance to ventricular filling
3. inflammation of the pericardial sac
4. stenotic mitral valve
Correct Answer: 1
A pathologic S3 is called a ventricular gallop and results from myocardial failure and ventricular volume overload. An S3 sound is not caused by increased resistance to ventricular filling, inflammation of the pericardial sac, or mitral valve stenosis.
