A nurse is preparing to teach the staff about asthma.Which information should the nurse include? Airway obstruction contributing to increased airflow resistance and hypoventilation in asthma is caused by:
A) Type II alveolar cell injury and decreased surfactant
B) Alveolar fibrosis and pulmonary edema
C) Mucus secretion, bronchoconstriction, and airway edema
D) Collapse of the cartilaginous rings in the bronchi

Question

Quizplus · Accepted Answer

The mediators of asthma cause vasodilation,increased capillary permeability,mucosal edema,bronchial smooth muscle contraction (bronchospasm),and mucus secretion from mucosal goblet cells with narrowing of the airways and obstruction to airflow.
Acute respiratory distress syndrome involves type II injury.
Alveolar fibrosis with pulmonary edema is not associated with asthma.
Asthma is not associated with collapse of bronchiolar rings.
