Question

a) At the sternal notch
b) Just above the nipple line
c) Just below the nipple line
d) The upper half of the sternum

Answer 1

The landmark for external cardiac compression on an infant should be at the sternal notch, which can be easily felt at the anterior base of the neck between the clavicles.

Step-by-step explanation:

The landmark for external cardiac compression on an infant should be at the sternal notch. The sternum is the elongated bony structure that anchors the anterior thoracic cage. The top of the manubrium has a shallow, U-shaped border called the jugular (suprasternal) notch, which can be easily felt at the anterior base of the neck, between the medial ends of the clavicles.
