Correct answer: B — PA chest radiograph and upper abdominal radiograph

A PA chest radiograph (including the upper abdomen) is the first-line imaging for suspected foreign body ingestion or aspiration. It will show: (1) if the object is in the airway (trachea/bronchus — emergency bronchoscopy needed); (2) if it is in the oesophagus (may need endoscopic retrieval if not progressing); or (3) if it is in the stomach/intestine (usually passes spontaneously). Metal objects (SSCs, files, posts) are readily visible on plain radiographs. Serial radiographs at 24-48 hour intervals may be needed to track progression through the GI tract.
