Which chest finding is a common physical manifestation of advanced COPD?

• A. Barrel chest due to hyperinflation and limited lung elasticity
• B. Pectus excavatum
• C. Intercostal retractions at rest
• D. Substernal goiter

Answer: (A)

Barrel-shaped chest caused by hyperinflation and loss of elastic recoil is a common physical finding in advanced COPD. In emphysema, alveolar walls are destroyed and air becomes trapped during expiration, so the lungs remain chronically overinflated. This expands the chest wall, increasing the anterior-posterior diameter and giving the chest a rounded, “barrel” appearance. You may also notice a flattened diaphragm, diminished breath sounds, and a prolonged expiratory phase on auscultation and percussion. Pectus excavatum is a congenital inward deformity of the sternum, not related to COPD. Intercostal retractions at rest point to acute respiratory distress rather than a chronic, hyperinflated state. Substernal goiter involves thyroid enlargement causing compression symptoms, not a characteristic COPD chest finding.
