Using a stepwise approach to managing asthma, a nurse teaches a patient who is at step 1 that their albuterol MDI (Proventil) is used:

If nighttime awakenings occur more than 2 days per week

Twice daily combined with an inhaled glucocorticoid

Only with a long-acting beta2 agonist (LABA)

As a rescue inhaler as needed for asthma symptoms
