Answer: C. In the urgent care setting, acute bronchiolitis is primarily a clinical diagnosis, so routine diagnostic testing is not recommended. Treatment for bronchiolitis is not determined by the causative agent, and there is currently no outpatient antiviral medication recommended for RSV, the most common cause of bronchiolitis. However, chest radiographs may be useful if there is concern for foreign body aspiration, cardiac disease, or pneumonia as the cause of wheezing, and testing for serious bacterial infections (eg, urinary tract infections) should be considered in febrile infants aged <60 days with bronchiolitis.
