Practice Question
Where does the nurse place their stethoscope to auscultate a patient's mitral valve?
Answer Choices:
Correct Answer:
5th ICS, LMCL (Intercostal space, left midclavicular line)
Rationale:
⭐ The mitral valve is best heard at the cardiac apex.
⭐ This location corresponds to the PMI where left-sided sounds are strongest.
⭐ S1 intensity is loudest here due to mitral valve closure.
⭐ The 5th ICS LMCL provides the clearest sound for mitral murmurs.
⭐ It aligns anatomically with the left ventricle, enhancing sound transmission.
2nd ICS RSB
⭐ This is the aortic area, not mitral.
⭐ Used to assess aortic stenosis.
Lower LSB
⭐ This corresponds to the tricuspid area.
⭐ Mitral sounds are too distant here.
2nd ICS LSB
⭐ This is the pulmonic listening point.
⭐ Mitral murmurs cannot be accurately identified from this site.
