Which agent is indicated for treatment of keloids and burns in this context?

• A. Zinc
• B. Acetate
• C. Lidocaine
• D. Chlorine

Answer: (D)

The main idea here is using an antiseptic to keep burn wounds clean and prevent infection, which is crucial for proper healing and reducing scar formation. Chlorine-based antiseptics (such as dilute sodium hypochlorite solutions) are effective broad-spectrum antimicrobials used to cleanse burn wounds and lower the microbial load without causing excessive tissue damage when used properly. This makes chlorine a good fit in a burn care context where infection control is a priority during healing. For keloids, treatment focuses on scar-specific therapies (like silicone, steroids, or laser) rather than antiseptics, so the emphasis is on preventing infection during the healing process rather than treating the scar itself. The other options don’t provide the needed antimicrobial action: zinc helps with healing and acts as a barrier, lidocaine is for pain relief, and acetate isn’t a standard antiseptic in this burn-care context.
