Which term best describes injuries considered serious due to the mechanism?

• A. High Mechanism
• B. Low Mechanism
• C. Cold Call
• D. Fourth Party

Answer: (A)

In trauma care, how an injury happened matters as much as what hurts. A high mechanism means the incident delivered a lot of energy—think high-speed crashes, falls from height, crush injuries, or significant blunt trauma. That energy can hide serious damage, so injuries from high-mechanism events are treated as potentially life-threatening even if outward signs seem mild. This is why high mechanism is used to indicate seriousness and triggers thorough assessment and rapid transport to a trauma-capable facility. In contrast, low mechanism describes lower-energy events, which are less likely to result in severe injury and may not require the same urgency. The other terms in the options aren’t about mechanism of injury and aren’t used to describe the seriousness of injuries in this context.
