Certified Wildlife Rehabilitator Practice Test

Which of the following should never be used to flush a flesh wound?

1. Normal saline solution

2. 3% hydrogen peroxide

3. Warm distilled water

4. Antiseptic solution

The correct answer is: 3% hydrogen peroxide

Using 3% hydrogen peroxide to flush a flesh wound is not appropriate because it can damage tissues and slow the healing process. Hydrogen peroxide is a potent oxidizing agent that, while it may be effective at killing some bacteria, can also harm the surrounding healthy cells necessary for wound repair. Its bubbling action may clean the surface, but it can lead to further tissue damage, inflammation, and potential complications in healing. In contrast, normal saline solution, warm distilled water, and antiseptic solutions are generally safer choices for flushing wounds. Normal saline is isotonic and gentle on tissues, making it effective for cleaning without causing additional harm. Warm distilled water can also be used to rinse a wound, as it is free from contaminants and safe for tissues. Antiseptic solutions, depending on their formulation, can help manage bacterial load while minimizing damage to healthy cells if used appropriately.
