Correct answer: D — Arrange emergent endoscopic removal for an oesophageal button battery
The best answer is “Arrange emergent endoscopic removal for an oesophageal button battery”. A double-ringed coin-shaped object is a button battery until proved otherwise. A button battery in the oesophagus requires emergent removal because tissue injury progresses rapidly, even if the child initially looks stable. Observation, laxatives and delayed imaging or endoscopy are appropriate for selected lower-risk objects, not this one.
