Which best describes a client's treatment priority in a mass casualty event?

In a mass casualty event, the treatment priority focuses on prioritizing care for those who are more critically injured. This strategy is central to the principles of triage, where the goal is to maximize the chances of survival and ensure that resources are utilized effectively. By assessing and treating the most critically injured clients first, healthcare providers can address life-threatening conditions that require immediate intervention.

This approach ensures that medical attention is directed where it is needed most, which can potentially save lives. It is based on the understanding that individuals with more severe injuries are at greater risk of mortality if not treated promptly. Therefore, those patients are prioritized to receive immediate care and resources, which is a fundamental concept in emergency medicine and disaster response.
