Which statement about burn injuries is true according to the material?

• A. First-degree burns involve only the outer skin layer and are painful
• B. All burns are equally severe regardless of depth
• C. Burns do not require treatment if minor
• D. Burns should be left untreated to heal naturally

Answer: (A)

The main idea is that burn depth dictates how serious the injury is and how it’s treated. First-degree burns affect only the epidermis, the outermost layer of skin. That superficial layer being irritated creates redness and pain, which is typical because the nerve endings in that layer are exposed. Because the damage is limited to the surface, these burns usually heal in a few days without scarring, with simple care such as cooling under lukewarm running water and keeping the area clean and protected. In a welding or hot-work setting, it’s still important to cool the burn promptly and monitor for signs that require medical attention, like a large area, involvement of sensitive areas, or signs of infection.

The other ideas don’t fit because depth matters: deeper burns extend into the dermis or beyond and can blister, be more painful or numb, and often need medical care; burns aren’t all equally severe. Minor burns still deserve basic first-aid care rather than being ignored, and leaving a burn untreated isn’t advisable.
