A patient with a COPD Action Plan calls the clinic reporting increased use of their rescue inhaler and a change in sputum color to yellow for the past 24 hours. These symptoms place them in the 'Yellow Zone'. According to a typical action plan, what is the MOST appropriate initial advice from the COPD educator?
-
A
Increase the use of the quick-relief inhaler as directed and consider starting the prescribed oral corticosteroid and/or antibiotic.
-
B
Immediately go to the nearest emergency department for evaluation.
-
C
Stop all maintenance inhalers and only use the quick-relief inhaler.
-
D
Schedule a routine follow-up appointment with the pulmonologist for next week.
