The parent of the 2-year-old with asthma has been given instructions about asthma control and Step Therapy. Which statement, if made by the parent, should indicate to the nurse that the parent has an adequate understanding of the instructions?

A: Asthma symptoms (wheezing) occurring 2 or fewer days per week should be treated at Step 1. B: A respiratory tract infection may require the increased use of short-acting beta agonists, but an inhaled corticosteroid should not be added until the child is evaluated by the HCP. C: The use of the nebulizer twice a week or less should be treated at Step 1. D: Nighttime waking with asthma symptoms 1 to 2 times per month indicates the need to proceed to Step 2 therapy, which includes the use of an inhaled corticosteroid.
