Which of the following abnormal breath sounds indicates obstruction of the upper airway?

Explanation:
Stridor points to an obstruction in the upper airway. It’s a high-pitched, harsh or musical sound usually heard during inhalation and seen when air is forced through a narrowed throat area above the vocal cords. This differs from wheeze, which comes from narrowed smaller airways in the lungs; crackles, which come from fluid or collapsed alveoli; and rhonchi, which are coarse sounds from secretions in larger airways. Because the problem is up high, stridor signals a potentially dangerous airway issue that often requires rapid assessment and airway support, including oxygen and readiness for advanced airway management.
