Final answer:
High-velocity trauma commonly results in fractures and severe bleeding, due to the significant force of impact leading to bone breaks and damage to the vascular system.
Step-by-step explanation:
Two common features in high-velocity trauma are fractures and severe bleeding. High-velocity trauma, such as that experienced in automobile accidents or falls, frequently results in fractures. These can vary in complexity and location, but types such as linear skull fractures, comminuted fractures, depressed fractures, and contrecoup fractures are indicative of the severe force associated with high-impact events. Bleeding, both internal and external, is also a major concern, often resulting from the severing of blood vessels or damage to internal organs.
