A client reports difficulty breathing and the nurse auscultates bilateral wheezing in the anterior upper lobes. Which rationale would explain this sound?

• A. High velocity airflow through an obstructed airway
• B. Fluid in the alveoli
• C. Consolidation of lung tissue
• D. Pneumothorax

Answer: (A)

Wheezes arise when air moves through narrowed or obstructed airways, causing turbulent, high-velocity flow that makes a musical, high-pitched whistle. In this case, the client’s difficulty breathing with bilateral wheezing in the anterior upper lobes fits bronchospasm or airway narrowing, which speeds the air as it tries to pass through constricted bronchial lumens. This explains the sound best: a narrow airway creates that characteristic wheeze as air is forced through remaining opening. Fluid in the alveoli would produce crackles from the alveoli popping open as fluid shifts, not a continuous musical wheeze. Consolidation of lung tissue tends to produce dullness on percussion and possibly increased breath sounds with crackles or bronchial breathing, not a clear wheeze. Pneumothorax often causes diminished or absent breath sounds and hyperresonance, rather than a persistent musical whine through narrowed airways.
