Which physical exam finding is typical in a patient with COPD?

In patients with Chronic Obstructive Pulmonary Disease (COPD), physical examination often reveals specific auscultatory findings that are characteristic of the disease. Decreased breath sounds are common, reflecting the airflow limitation and air trapping present in COPD. This occurs due to the destruction of alveolar walls and loss of elastic recoil, which impacts airflow during expiration.

Additionally, wheezing can be heard as a continuous musical sound during expiration. This wheezing is a result of narrowing of the airways due to inflammation and bronchoconstriction, a hallmark of COPD. Rales, or crackles, may also be auscultated, particularly in the presence of mucus obstruction in the airways or if there is associated bronchitis.

This combination of decreased breath sounds, wheezing, and rales fits the typical profile for COPD patients, as these findings reflect the pathological changes in the lungs associated with the condition. Other options do not accurately represent common findings in this patient population.
