Which statement below differentiates asthma from chronic obstructive pulmonary disease (COPD)? A) Asthma is characterized by a decrease in oxygen saturation whereas COPD is characterized by an increase in oxygen saturation B) Asthma is an obstructive disease whereas COPD is an acute disorder C) Smoking makes asthma worse whereas smoking has no effect on COPD D) Airflow obstruction caused by asthma is reversible whereas airflow obstruction in COPD is irreversible
Understand the Problem
The question is asking for a statement that distinguishes asthma from chronic obstructive pulmonary disease (COPD) based on their characteristics or effects. It presents four options, each providing a different comparison between the two conditions.
Answer
D) Airflow obstruction caused by asthma is reversible whereas airflow obstruction in COPD is irreversible
The final answer is D) Airflow obstruction caused by asthma is reversible whereas airflow obstruction in COPD is irreversible
Answer for screen readers
The final answer is D) Airflow obstruction caused by asthma is reversible whereas airflow obstruction in COPD is irreversible
More Information
A key difference between asthma and COPD is the reversibility of airflow obstruction in asthma, which is not typically reversible in COPD.
