Final answer:
In the event of a chemical eye injury from battery acid, the nurse should immediately irrigate the eye with water to dilute and remove the chemical.
Step-by-step explanation:
If a client sustains a chemical eye injury from a splash of battery acid, the nurse should prepare the client for immediate irrigation of the eye with water. This is critical to help dilute and remove the chemical from the eye surface to minimize damage. Chemicals such as battery acid can cause severe irritation or damage to the eyes and skin due to their corrosive nature. In the case of eye exposure, irrigating the eye with copious amounts of water is the most important initial step. Warm compresses, eye drops, or antibiotic ointments are not appropriate immediate measures following a chemical injury to the eye.
