The pulmonic valve is described as being close to which anatomical landmark?

• A. Sternum
• B. Spine
• C. Left shoulder
• D. Diaphragm

Answer: (A)

The important idea is how heart valves relate to external chest landmarks. The pulmonic valve sits high in the chest, near the left upper sternal border around the second intercostal space, close to the sternum. That anterior, central location is why it’s described as being near the sternum. The other landmarks aren’t used to describe its position: the spine is posterior, the left shoulder isn’t a fixed intrathoracic landmark for valve location, and the diaphragm lies well below the valve region. Clinically, you’d also listen for pulmonic sounds best at the left second intercostal space near the sternal border.
