A 28-year-old patient has symptoms of asthma daily and several nights a week. She uses a short-acting beta agonist (SABA), and the NP decides to initiate fluticasone/salmeterol (Advair). The NP should explain to the patient that Advair:
A) is NOT effective during an acute asthma attack.
B) may not produce improvements for 2 to 3 weeks.
C) works within 5 minutes of inhaling if administered appropriately.
D) contains only a long-acting beta agonist (LABA).
