Final answer:
The adventitious breath sound produced by narrowed inflamed airways is Wheezes. These high-pitched sounds result from turbulent airflow through constricted bronchial tubes and differ from stridor, friction rub, and crackles, which have other causes and characteristics.
Step-by-step explanation:
The adventitious breath sound generated by narrowed inflamed airways is D. Wheezes. Wheezes are high-pitched sounds that may occur both during inspiration and expiration, caused by the turbulent airflow through constricted bronchial tubes, often due to asthma, chronic obstructive pulmonary disease (COPD), or bronchitis. In contrast, stridor is a harsh, sound more common during inspiration and associated with obstruction in the trachea or larynx, friction rub is associated with inflammation of the pleura, and crackles are usually caused by fluid in the airways.
