Q. A 10-year-old boy was accompanied by his mother to your clinic after she received a call from his school that the boy has been experiencing recurring episodes of wheezing and coughing for the past month. His mother notes that these symptoms have become more frequent, particularly during his recent participation in school sports activities. His vital signs include a temperature of 98.6°F (37°C), a pulse rate of 88 beats per minute, blood pressure measuring 110/70 mmHg, and a respiratory rate of 14 breaths per minute. During the physical examination, you observe prolonged expiration and detect wheezing upon auscultation. What is the most appropriate next step in managing this patient's condition?
