When auscultating the lungs of a newborn, the systematic approach involves starting from which side?

Auscultating the lungs of a newborn is a critical skill that requires systematic techniques to ensure accuracy and thoroughness. Starting from the right side to the left side aligns with the common practice of examining patients systematically, as it helps maintain consistency in assessment and comparison.

The anatomical positioning of the heart and the majority of lung sounds also support this direction, as the right lung is often considered slightly larger and has three lobes, while the left has two. This approach allows clinicians to better assess for normal lung sounds and detect any abnormalities, such as wheezing or crackles, by comparing corresponding areas systematically.

This method also ensures that the healthcare professional does not miss any important sounds that may vary from one lung field to another due to the mechanics of breathing, potential conditions, or the positioning of the newborn. Starting on the right side helps in creating a clear and methodical patter, which can enhance the reliability of the findings.
