What is the immediate action a nurse should take for a patient who got bleach in their eye?

In the event of a chemical exposure to the eye, the primary concern is to minimize damage and facilitate immediate removal of the irritant. Starting eye irrigation as soon as possible is critical because it helps to flush out the bleach or any chemical agent that may cause harm. This action reduces the possibility of severe injury or permanent damage to the eye.

It's important to use a large volume of water or saline for flushing, ensuring that the solution flows from the inner corner of the eye to the outer corner. This technique helps to wash away the chemical and prevent it from coming into contact with the rest of the eye. Initiating this process quickly is essential for preserving eyesight and preventing further complications.

The other options, while they may seem relevant in other contexts, do not address the immediate need to remove the chemical irritant. For instance, assessing visual acuity first delays the necessary intervention. Providing cool fluids to drink does not aid in eye decontamination, and applying a bandage could potentially trap the chemical against the eye, exacerbating the injury. Thus, starting eye irrigation immediately is the most critical and appropriate response in this scenario.
