Correct answer: A — Chest X-ray

In a stable child with suspected foreign body aspiration, a chest X-ray (inspiratory and expiratory or bilateral decubitus views) should be obtained first. Hyperinflation of the affected lung due to a ball-valve effect may be seen. If clinical suspicion remains high despite a normal X-ray, rigid bronchoscopy should be performed.
