The nurse teaches a patient who has asthma about peak flow meter use. Which action by the patient indicates that teaching was successful?
a. The patient inhales rapidly through the peak flow meter mouthpiece.
b. The patient takes montelukast (Singulair) for peak flows in the red zone.
c. The patient calls the health care provider when the peak flow is in the green zone.
d. The patient uses albuterol (Proventil) metered dose inhaler (MDI) for peak flows in the yellow zone.
ANS: D
Readings in the yellow zone indicate a decrease in peak flow. The patient should use short-acting ?2-adrenergic (SABA) medications. Readings in the green zone indicate good asthma control. The patient should exhale quickly and forcefully through the peak flow meter mouthpiece to obtain the readings. Readings in the red zone do not indicate good peak flow, and the patient should take a fast-acting bronchodilator and call the health care provider for further instructions. Singulair is not indicated for acute attacks but rather is used for maintenance therapy.
