What condition is characterized by lower airway edema, bronchospasms, and hypermucous secretion?

Asthma
ARDS
Emphysema
Pulsus paradoxus

Explanation

Answer - A - Asthma is characterized by lower airway edema, bronchospasm, and hypermucous secretion. This is the classic pathophysiological triad of asthma. The first phase of asthma is the release histamine. This causes contraction of the bronchial smooth muscle and leakage of fluid from the capillaries. This results in both bronchoconstriction and bronchial edema.
