Correct answer: E — Give 10 mL honey every 10 minutes for up to six doses without delaying removal

The best answer is “Give 10 mL honey every 10 minutes for up to six doses without delaying removal”. In a child at least 12 months old whose lithium battery was swallowed within 12 hours, honey can mitigate esophageal injury while urgent removal is arranged. It must not delay endoscopy; vomiting should not be induced and charcoal does not neutralize the battery mechanism.
