Question

which of the following is not a recognized cause of bronchiectasis? please select your answer... a cystic fibrosis b chronic pulmonary embolism c ciliary dyskinesia

Explanation:

Bronchiectasis is a condition where the airways in the lungs become damaged and widened. Cystic fibrosis (A) is a genetic disorder that can lead to thick mucus production, which can cause bronchiectasis. Ciliary dyskinesia (C) affects the function of cilia (tiny hair - like structures in the airways that help move mucus), and if cilia don't work properly, mucus can accumulate and cause bronchiectasis. Chronic pulmonary embolism (B) mainly affects the blood vessels in the lungs (causing blockages in the pulmonary arteries) and is not a recognized direct cause of bronchiectasis.

Answer:

B. Chronic pulmonary embolism
