A thorough physical examination is essential for assessing the pediatric thorax. This includes visual inspection, palpation, percussion, and auscultation: - Inspection: Observing the shape, symmetry, and movement of the chest. - Palpation: Checking for tenderness, deformities, or abnormal masses. - Percussion: Tapping on the chest to evaluate underlying structures. - Auscultation: Using a stethoscope to listen to breath sounds and heartbeats, identifying abnormalities such as wheezing, crackles, or murmurs.
