A patient with asthma is prescribed albuterol (Proventil) as needed and salmeterol (Serevent) every 12 hours. When the patient asks the nurse why two inhaler drugs are needed, what is the nurse's best response?
a. "Albuterol opens your airways and salmeterol decreases the inflammation."
b. "I will check with the prescriber to determine whether you can just use one drug."
c. "Albuterol is a rescue drug to stop asthma attacks and salmeterol prevents at-tacks."
d. "Salmeterol helps you breathe better and albuterol opens alveoli for gas ex-change."
C
Even though both drugs are beta2 agonists, they are both normally prescribed for the patient with asthma. Short-acting (but rapid-acting) beta2 agonists (albuterol) are used to reduce the severity or stop an asthma attack. Long-acting beta2 agonists (salmeterol) can prevent attacks when taken daily; however, their onset of action is so slow that these drugs are not helpful to stop an attack that has already started.
