Kelly calls about her 10-year-old son, Bryan. Bryan has been coughing and wheezing intermittently for the last 12 hours, but it seems to have gotten worse. She gave Bryan 2 puffs of his albuterol inhaler about 2 hours ago. He still has continuous cough and intermittent wheezing. What is the most probable pathophysiology of the symptoms? This sounds like bronchiolitis This sounds like an upper respiratory infection This sounds like an asthma attack This sounds like an allergic reaction
