In the case of a laceration to the eyeball or globe, what should you do?

Covering both eyes and stabilizing the head is the appropriate response to a laceration of the eyeball or globe. This approach is important because the eyes work in tandem, and if one eye is injured, covering it helps reduce the risk of movement and further damage to the injured eye. Additionally, stabilizing the head minimizes any potential movement that could exacerbate the injury.

Covering the unaffected eye can also help in reducing sympathetic movement, where the uninjured eye may inadvertently move in response to visual stimuli, which can aggravate the condition of the injured eye. Keeping the head still is crucial in managing such serious eye injuries, as any unnecessary movement could further compromise vision or potentially lead to more severe complications.

The other options do not adequately address the immediate need to stabilize the injury and prevent further damage. Elevating the head and applying pressure or flushing the eye with saline do not provide the same level of protection for the injured eye as covering both eyes does, especially in cases of potential globe perforation.
