Project Summary: Joshua Martin is a 5-year-old boy who started kindergarten this year. Joshua's wheezing intensifies after he lies on the floor mats in his classroom for a nap. Joshua receives albuterol (a β2-agonist) treatments four to five times a year in the emergency department for this condition and experiences temporary relief of symptoms. The school nurse's observations of Joshua include the following: absence of fever or sore throat, persistent dry cough, wheezing, exercise intolerance, and a history of resolution of symptoms after β2-agonists treatments. After a pulmonary function test is done at his pediatrician’s office, it is determined that Joshua has moderate persistent asthma and allergic rhinitis.
