Which of the following is a major category covered in trauma incidents?

In the context of trauma incidents, categories typically focus on acute physical injuries resulting from external forces. Trauma encompasses a broad range of events, including those that cause significant and immediate physical harm, such as motor vehicle accidents, falls, and violence. Within this framework, burns represent one of the major categories of trauma-related injuries. They can result from a variety of sources, including heat, chemicals, electricity, or radiation, and often require immediate medical intervention due to the potential for serious complications.

The other options, while important in the broader field of healthcare, do not fit within the major categories that specifically pertain to trauma incidents. Heart diseases and infectious diseases are primarily classified as medical emergencies rather than trauma. Cognitive impairments may be relevant in certain contexts but also do not fall under the traditional classifications of traumatic injuries. Thus, burns, as a distinct and prominent form of trauma, is indeed the correct answer in this context.
