Explanation

The primary goal in treating a chemical burn is to stop the burning process as quickly as possible.
Irrigating the wound with a large volume of water effectively dilutes the chemical and flushes it from the skin surface.
This immediate action minimizes the duration of contact between the chemical and the skin, which directly reduces the severity and depth of the injury.
According to emergency nursing principles, prolonged lavage with generous amounts of tepid water is the standard of care for most chemical skin contaminations.

Option B: Administering 20 ml of normal saline is a grossly insufficient volume for decontamination. Chemical burns require copious and continuous flushing to be effective.
Option C: Applying an antibiotic solution is not the first-line treatment. The priority is to remove the offending chemical. Furthermore, the antibiotic might react with the chemical, and its application delays the crucial step of irrigation.
Option D: Waiting to identify the chemical before starting treatment is dangerous and can lead to severe, irreversible tissue damage. Time is critical, and immediate irrigation should not be delayed.

Clinical Relevance

Nursing practice connection: Use the key finding related to First aid and emergency management of chemical burns to guide bedside assessment, documentation, and the next nursing action.
In a clinical setting, a nurse's first action for a chemical burn is to ensure their own safety with PPE and then immediately begin decontamination with water or saline via a shower or irrigation setup.
Failure to irrigate immediately and sufficiently can result in a more severe burn, deeper tissue necrosis, prolonged healing, significant scarring, and increased risk of infection.
Patient safety is paramount. Do not waste time searching for a specific neutralizing agent, as this is generally contraindicated and can worsen the injury.

How to Approach the Question

First, identify the core of the question: it asks for the 'primary intervention' for a chemical burn. This signals a priority-setting question.
Recall the fundamental principle of treating burns and poisonings: stop the source of the injury.
For chemical burns, the 'source' is the ongoing chemical reaction on the skin. The fastest way to stop this is by removing the chemical.
Evaluate the options based on this principle. 'Washing with copious water' directly addresses the removal of the chemical.
Consider the other options: 20 ml of saline is too little, antibiotics are for infection prevention (a later step), and waiting is always detrimental in an emergency where tissue is being actively damaged.
Conclude that immediate, large-volume irrigation is the most effective and critical first step.
