The nurse caring for a patient with coronary artery disease hears a murmur during auscultation of the heart. What should the nurse suspect is occurring in this patient?
1. valvular heart disease
2. pericarditis
3. cardiac tamponade
4. heart failure
Correct Answer: 1
Valvular heart disorders interfere with the smooth flow of blood through the heart. The flow becomes turbulent, causing a murmur, a characteristic manifestation of valvular disease. The heart sound characteristic of pericarditis is a pericardial friction rub. Distant and muffled heart sounds are typical of cardiac tamponade. Extra heart sounds S3 and S4 are heard in heart failure.
