Burns can be caused by which of the following sources?

Burns can result from a variety of sources, and understanding these sources is essential in both treatment and prevention. The correct answer encompasses three categories: thermal, chemical, and electrical sources.

Thermal burns occur from exposure to heat sources such as flames, hot liquids, or steam. These are the most common types of burns and typically result from cooking accidents, house fires, or scalding.

Chemical burns arise when skin or eyes come into contact with caustic substances like acids or alkalis. These burns can cause significant and sometimes delayed damage depending on the type and concentration of the chemical involved.

Electrical burns occur due to electrical currents passing through the body, which can lead to deep tissue damage even if the skin surface appears unharmed. The severity can vary widely based on the voltage and duration of contact with the electrical source.

The other options are limited in scope. Some focus on only one source, which does not encompass the full range of burn causes, while others combine sources that do not typically lead to burns, such as mechanical sources that are more associated with trauma than thermal injury. Understanding the full spectrum of burn sources is crucial for effective treatment and safety awareness.
