What best defines burns?

What best defines burns?

• A. Tissue damage caused by heat, chemicals, electricity, or radiation.
• B. A mild sunburn.
• C. A skin irritation caused by friction.
• D. A temporary discoloration of the skin.

Answer: (A)

Burns are injuries to tissue caused by exposure to heat, chemicals, electricity, or radiation. This broad definition covers all the common ways tissue can be damaged. A mild sunburn is an example of a burn because UV radiation causes tissue injury, but it’s just one specific instance within the broader category. A skin irritation from friction isn’t a burn, since it isn’t caused by those damaging agents. Temporary discoloration might appear with burns, but it doesn’t define the injury itself.
