Which is a priority action when managing a severe eye injury?

In the case of a severe eye injury, keeping the casualty calm and covering both eyes is a priority action because it helps prevent further damage to the injured eye and minimizes the risk of any inadvertent movements that could worsen the situation. Keeping both eyes covered can also reduce the chance of light exposure, which may cause discomfort or increased pain. Additionally, maintaining calmness in the casualty can help manage anxiety and stress, which may exacerbate the perception of pain or lead to erratic movements that could affect the injury.

The other options do not prioritize what needs to be done in a severe eye injury scenario. Rubbing the eye could lead to additional trauma, while applying ice directly can increase risk of frostbite and does not correctly address the underlying injury. Flushing the eye might be suitable in situations involving foreign bodies or chemical exposure but isn’t necessarily the best immediate action for all types of severe eye injuries, especially if there is a risk of further damage. Thus, prioritizing calmness and protecting both eyes is a more effective and safer response.
