A patient with stable COPD receives prescriptions for an inhaled glucocorticoid and an inhaled beta2-adrenergic agonist. Which statement by the patient indicates understanding of this medication regimen?

I should use the glucocorticoid as needed when symptoms flare.

I will need to use the beta2-adrenergic agonist drug daily even when I don't have any symptoms.

The beta2-adrenergic agonist suppresses the synthesis of inflammatory mediators.

The glucocorticoid is used as prophylaxis to prevent exacerbations every day.
