AHN 568 Exam 2 Cardiac Assessment
The bell of your stethoscope can be used to detect low pitch sounds including S3, S4,
and which diastolic murmur?
- Aortic stenosis
- Pulmonic Stenosis
- Mitral Stenosis
- Mitral regurgitation - ✔️✔️Mitral stenosis - this is the only diastolic murmur listed. The
bell of the stethoscope will also detect this sound as well as S3 and S4.
A patient presents with complaints of swelling in their ankles and shortness of breath.
Physical exam reveals JVD, 2+ pitting edema, enlarged spleen, and crackles in their
lungs. Which heart sound would expect to hear upon auscultation with the bell of your
stethoscope? - ✔️✔️S3 - associated with fluid overload and heart failure.

Late closure of the pulmonic valve
S1 is the closure of the ________&________ valve - ✔️✔️mitral & tricuspid
(atrioventricular)
S1 marks the beginning of systole or diastole - ✔️✔️systole
