Wheezes are best described as?

• A. Continuous, high-pitched musical sounds from narrowed airways
• B. Stridor heard on inspiration
• C. Fine crackles on auscultation
• D. Absent breath sounds

Answer: (A)

Wheezes happen when air moves through narrowed airways, producing a continuous, high-pitched musical sound. This whistling quality is most noticeable during expiration when the airway obstruction is greatest, and it’s characteristic of lower airway narrowing seen in conditions like asthma or COPD. This differs from stridor, which is an inspiratory, harsh sound indicating upper airway obstruction and is not a musical wheeze. Fine crackles are brief, crackling sounds from fluid in the small airways or alveoli, not a persistent whistle. Absent breath sounds point to more severe problems, such as a large pneumothorax or complete airway collapse, and not to wheezing.
