Final answer:
The ED nurse should prioritize the child's airway, breathing, and circulation (ABCs) when caring for a child who has ingested kerosene and is lethargic, grunting, and gagging. Immediate assessment of the child's respiratory status, administration of oxygen if necessary, and ensuring a clear airway are crucial steps. Monitoring vital signs, providing supportive care, and seeking guidance from a physician or poison control center are also important.
