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?

Choice A reason: The patient should not use the glucocorticoid as needed when symptoms flare. The glucocorticoid is a long-term controller medication that reduces inflammation and prevents exacerbations of COPD. It should be used regularly as prescribed, not as a rescue medication. Choice B reason: The patient does not need to use the beta2-adrenergic agonist drug daily even when they don't have any symptoms. The beta2-adrenergic agonist is a short-acting bronchodilator that relaxes the smooth muscles of the airways and improves airflow. It should be used as needed for relief of acute symptoms, not as a maintenance medication. Choice C reason: The beta2-adrenergic agonist does not suppress the synthesis of inflammatory mediators. The beta2-adrenergic agonist is a bronchodilator that acts on the beta2 receptors of the airways and causes relaxation of the smooth muscles. It does not have any anti-inflammatory effects. Choice D reason: The glucocorticoid is used as prophylaxis to prevent exacerbations every day. This is the correct statement that indicates understanding of this medication regimen. The glucocorticoid is a long-term controller medication that reduces inflammation and prevents exacerbations of COPD. It should be used regularly as prescribed, along with the beta2-adrenergic agonist as needed for relief of acute symptoms.
