A)An obstructive airway disease characterized by reversible airflow obstruction, bronchial hyperreactivity, and inflammation
B)A pulmonary disease characterized by severe hypoxemia, decreased pulmonary compliance, and the presence of bilateral infiltrates on chest x-ray imaging
C)A respiratory disorder involving an abnormal expression of a protein producing viscous mucus that lines the airways, pancreas, sweat ducts, and vas deferens
D)A pulmonary disorder characterized by atelectasis and increased pulmonary resistance as a result of a surfactant deficiency

Question

Quizplus · Accepted Answer

ARDS is a condition that can result from either a direct or indirect pulmonary insult. It is defined as respiratory failure of acute onset characterized by severe hypoxemia that is refractory to treatment with supplemental oxygen, bilateral infiltrates on chest x-ray imaging, and no evidence of heart failure, as well as decreased pulmonary compliance. The disorder with reversible airflow limitation is asthma. The disease with viscous mucus that lines the airways and other organs and tissues is cystic fibrosis. A surfactant deficiency occurs in RDS of the newborn.
