Question

continuous high-pitched whistling sounds, usually during expiration, are called:
a rhonchi
b rales
c stridor
d wheezes

Explanation:

To solve this, we analyze each option:

• Option A: Rhonchi are low - pitched, coarse, rattling respiratory sounds, not high - pitched whistling.
• Option B: Rales (crackles) are discontinuous, non - musical sounds like popping, not continuous whistling.
• Option C: Stridor is a high - pitched sound, but it mainly occurs during inspiration (related to upper airway obstruction), not usually expiration.
• Option D: Wheezes are continuous, high - pitched, whistling sounds, and they often occur during expiration due to narrowed airways (e.g., in asthma).

Answer:

D. wheezes
