Prior to the start of these symptoms, the parent recalls a coughing event which resolved spontaneously. Of the following the most likely diagnosis is: a. Viral pneumonia b. Acute laryngotracheobronchitis c. Bronchiolitis d. Foreign body aspiration - d. Foreign body aspiration Rationale: An initial choking, gagging, or coughing episode following by spontaneous resolution is often present in history finding of a child with foreign body aspiration.
