A student got chemical burn while working in the lab. As a school nurse, which of the following intervention you will do to reduce the severity of the burn?

1. A

   Immediately cover the area

2. B

   Apply antidote solution

3. C

   Remove skin from burned area

4. D

   Flush the area with water

Appeared in: GMCH Nursing Officer-2025

Explanation

• The priority action for a chemical burn is to stop the burning process by removing the chemical agent.
• Flushing the area with large amounts of running water for an extended period (at least 20-30 minutes) effectively dilutes and washes away the chemical.
• This immediate intervention significantly reduces the severity of the burn and prevents deeper tissue damage.
• This is the universally accepted first-aid standard for most chemical exposures on the skin.

Why Other Options Were Wrong

• Option A: Covering the area without decontamination will trap the chemical against the skin, prolonging exposure and worsening the burn.
• Option B: Applying an antidote or neutralizing agent is not recommended as a first-line treatment. The neutralization reaction can be exothermic (produce heat), causing an additional thermal burn.
• Option C: Removing skin is a debridement procedure that must be performed by a healthcare professional. Attempting this as first aid can cause severe pain, increase the risk of infection, and lead to further injury.

Clinical Relevance

• Nursing practice connection: Knowing First Aid Management of Chemical Burns helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
• As a school nurse, knowing the correct, immediate response to a chemical burn is critical for preventing severe injury and long-term complications in students.
• This knowledge is essential for emergency preparedness in any setting with chemicals, such as science labs or cleaning supply areas.
• What if the chemical was a dry powder? The protocol changes slightly. The first step would be to carefully brush off as much of the powder as possible before flushing with water. Adding water to certain dry chemicals (like lye or white phosphorus) can create a reaction that intensifies the burn.

How to Approach the Question

• Identify the question type: This is a clinical scenario question asking for a priority nursing intervention.
• Analyze the scenario: The key elements are 'chemical burn' and 'immediate action to reduce severity'.
• Evaluate the core problem: The chemical is actively causing tissue damage. The priority must be to stop this process.
• Assess the options based on the core problem: Which option most directly and safely stops the chemical from causing further damage?
• Option A (Cover) traps the chemical. Incorrect.
• Option B (Antidote) can cause a secondary burn. Incorrect and not the first priority.
