A.K. is а 9-yeаr-оld bоy whо presents to аn urban ED with cough and trouble breathing typical of his usual asthma exacerbation. This episode began 2 days ago and has been accompanied by a runny nose and a low-grade fever without any other symptoms. Several family members are also ill with upper respiratory infections. His mother has been treating him with albuterol by a nebulizer every 4 hours, but he has become more short of breath this evening prior to coming to the ED. Past medical history is notable for asthma/RAD since infancy, with multiple prior hospitalizations. Other problems on review of systems include eczema and environmental allergies. Multiple family members also have asthma. On social history, his mother mentions that he is in second grade but has missed at least 10 days of school this year due to his asthma. In the past, his primary care has been inconsistent, although recently the family obtained health insurance and he has been assigned to a new provider. His only current medication is albuterol. In the past, he was prescribed inhaled fluticasone, but the prescription ran out and the family has not followed up for a refill. On physical examination, he appears in moderate respiratory distress, with suprasternal and intercostal retractions. His vital signs include a temperature of 100.1°F, a respiratory rate of 40 breaths per minute, heart rate of 120 beats per minute, and pulse oximetry of 95% on room air. Lung exam is notable for diffuse symmetrical wheezes, a prolonged expiratory phase, and diminished aeration. His nasal mucosa is erythematous with boggy turbinates and clear mucus. His skin is dry with excoriation over the flexor creases. The remainder of the examination is unremarkable. What is your initial treatment plan, medications, testing, and follow up?
