A client says to you, My medications arent working. Im still short of breath even after using those puffers! You review the clients chart and note the diagnosis of chronic obstructive pulmonary disease (COPD). The client is prescribed two inhalers, one a combination of fluticasone and salmeterol (Advair diskus) to be used twice daily and the other, albuterol (Ventolin) PRN for episodes of shortness of breath..
