Which is NOT one of the five traditional auscultatory areas?

• A. Aortic Valve Area
• B. 2nd Pulmonic (Erb's) Area
• C. Mitral (apical) Area
• D. Posterior Tibial Area

Answer: (D)

Auscultation of the heart relies on fixed listening posts that line up with the heart valves. The five traditional areas are the aortic area (right sternal border, 2nd intercostal space), the pulmonic area (left sternal border, 2nd intercostal space), Erb’s point (left sternal border, 3rd intercostal space), the tricuspid area (left lower sternal border, around the 4th–5th intercostal space), and the mitral/apical area (left 5th intercostal space at the midclavicular line). The posterior tibial area is not used for heart sounds; it’s a site to palpate the posterior tibial pulse as part of peripheral vascular assessment. So the posterior tibial area does not belong to the traditional auscultatory sites.
