To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client's caregivers?

A. Clients using the discus may experience decreased blood pressure: Fluticasone propionate and salmeterol are a combination of a corticosteroid and a long-acting beta-agonist. While they help control asthma, they are not typically associated with decreased blood pressure. Instead, potential side effects might include increased heart rate or hypertension. B. Explain that the client should not use the discus more than twice daily: Fluticasone propionate and salmeterol combination inhalers are usually prescribed for twice-daily use to maintain control of asthma symptoms. Using the inhaler more frequently than prescribed could lead to increased side effects or diminished effectiveness. C. When using the discus, have the client breathe out rapidly into the mouthpiece: The correct technique for using a dry powder inhaler involves inhaling deeply and forcefully to ensure the medication reaches the lungs. Breathing out rapidly into the mouthpiece is incorrect and will not deliver the medication effectively. D. Offer the discus to the client for use during an acute asthma attack: The discus is used for long-term control and prevention of asthma symptoms, not for immediate relief during an acute asthma attack. A rescue inhaler, typically containing a short-acting beta-agonist like albuterol, is used for acute symptoms.
