Bilateral wheezing in the upper lung regions is most consistent with which pathophysiological process?

• A. High velocity airflow through an obstructed airway
• B. Fluid in the air sacs
• C. Collapsed lung tissue
• D. Pneumonia with crackles

Answer: (A)

Wheezes happen when air has to squeeze through narrowed airways, causing turbulent, high-velocity flow that makes the airway walls vibrate. When you hear wheezing in multiple regions of the lungs, it points to obstruction in the larger, central airways allowing air to rush through more quickly than normal. That’s why the best match is the description of high velocity airflow through an obstructed airway. Fluid in the air sacs would produce crackles from fluid in the alveoli rather than wheezes. Collapsed lung tissue typically lowers or absent breath sounds in the affected area rather than producing wheezes. Pneumonia with crackles also tends to cause crackling sounds rather than the classic wheeze.
