Question

A 47-year-old man with a history of cough has the following spirometry results:  These findings show the presence of which of the following?
A) Reversible airway obstruction 
B) Moderate obstructive disease 
C) Normal lung function 
D) Incorrectly selected predicted values

Quizplus · Accepted Answer

The spirometry results show a reduced Forced Expiratory Volume in one second (FEV1) and a reduced FEV1/FVC ratio, which indicates obstruction in the airways. The severity of obstruction would be classified as moderate based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. There is no evidence of reversibility since there was no significant improvement in FEV1 after administering bronchodilator medication, ruling out option A. There is also no evidence of normal lung function or incorrectly selected predicted values based on the spirometry results.
