Which physical exam finding is characteristic of asthma?

• A. Shortness of breath
• B. Wheezing
• C. Chest tightness
• D. Prolonged expiration

Answer: (B)

Wheezing is a characteristic physical exam finding in asthma due to the narrowing of the airways, which can occur as a result of bronchoconstriction, inflammation, or increased mucus production. This narrowing produces a high-pitched whistling sound during breathing, particularly during expiration. While shortness of breath, chest tightness, and prolonged expiration are also common symptoms associated with asthma, wheezing stands out as a specific finding that is directly observable during the physical examination. It indicates the presence of airflow obstruction and is an essential component in diagnosing and assessing the severity of asthma.
