Explanation

The primary goal in a chemical eye injury is to dilute and remove the harmful substance as quickly as possible to prevent ongoing tissue damage.
Immediate and copious irrigation with water or normal saline is the most effective method to achieve this, directly addressing the cause of the injury.
This action minimizes the duration of contact between the chemical and the cornea, which is the most critical factor in determining the long-term visual prognosis.
Alkali burns are particularly dangerous as they penetrate tissue rapidly; therefore, any delay in irrigation significantly worsens the outcome.

Option A: Covering the eye traps the chemical against the cornea, which intensifies the burn and can lead to more severe, irreversible damage.
Option C: Antibiotic ointment does not neutralize or flush out chemicals. Applying it initially would be ineffective and could trap the substance, worsening the injury.
Option D: The immediate priority is to stop the chemical from burning the eye tissue. Pain management is a secondary concern.

Clinical Relevance

Nursing practice connection: Use the key finding related to First-aid management for chemical eye injuries to guide bedside assessment, documentation, and the next nursing action.
In any chemical eye injury, the principle 'time is tissue' applies. The nurse's ability to initiate immediate irrigation, even with simple tap water, can be the difference between temporary irritation and permanent blindness.
Patient education on workplace and household safety is a key nursing role to prevent such injuries, especially regarding the use of protective eyewear when handling chemicals.
What if? If the injury was from a solid foreign body (like a metal shard) instead of a chemical splash, the priority changes. You would NOT irrigate forcefully. Instead, you would stabilize the object, cover the eye with a protective shield (like a paper cup) without applying pressure, and seek immediate medical help. Attempting to remove a penetrating object can cause more damage.

How to Approach the Question

First, identify the question type. This is a priority-based question asking for the 'immediate first-aid intervention'.
Analyze the clinical scenario: a chemical is in the eye. The core problem is ongoing tissue damage from the chemical.
Evaluate each option based on its ability to solve the core problem. The primary goal must be to remove or neutralize the harmful agent.
Option A (covering) makes the problem worse. Option C (ointment) is for a later stage (infection prevention). Option D (anaesthetic) addresses a symptom (pain), not the cause.
Option B (irrigation) is the only choice that directly addresses the removal of the chemical, making it the highest priority and correct first-aid action.
