Which statement best describes cystic fibrosis?
A)Obstructive airway disease characterized by reversible airflow obstruction, bronchial hyperreactivity, and inflammation
B)Respiratory disease characterized by severe hypoxemia, decreased pulmonary compliance, and diffuse densities on chest x-ray imaging
C)Pulmonary disorder involving an abnormal expression of a protein-producing viscous mucus that obstructs the airways, pancreas, sweat ducts, and vas deferens
D)Pulmonary disorder characterized by atelectasis and increased pulmonary resistance as a result of a surfactant deficiency

Question

Quizplus · Accepted Answer

Cystic fibrosis is best described as a pulmonary disorder involving an abnormal expression of a protein-producing viscous mucus that obstructs the airways, pancreas, sweat ducts, and vas deferens. Reversible airflow limitations are seen in asthma. Severe hypoxemia and diffuse densities seen on x-ray are characteristic of ARDS. Surfactant deficiency leads to RDS of the newborn.
