Final answer:
The most appropriate treatment for a construction worker with a large sliver of metal impaled in his right eye is to seek immediate medical attention.
Step-by-step explanation:
The most appropriate treatment for a construction worker who has a large sliver of metal impaled in his right eye is to seek immediate medical attention. This is because removing the sliver of metal using tweezers can cause further damage and may not be recommended. Flushing the eye with clean water can help to rinse out any foreign particles but it may not be sufficient in removing the sliver. Covering the eye with a sterile dressing can provide some protection but does not address the underlying issue.
