Which triage classification of clients requires an urgent nursing priority in case of a mass casualty?

In a mass casualty situation, triage classifications are used to prioritize care based on the severity of injuries and the likelihood of survival with immediate treatment. Class 1 is assigned to patients needing immediate care to survive, typically those who have life-threatening injuries but can benefit from quick medical intervention. Class 2 patients are those who have serious but not immediately life-threatening conditions; they require urgent care, but their situation is not as critical as Class 1.

Choosing Class 2 as the answer reflects an understanding that, while these clients require timely attention, the priority level in a mass casualty incident is generally reserved for Class 1 patients first. Nevertheless, Class 2 clients support the overall flow of triage by ensuring severe injuries are identified and managed quickly if resources allow.

Class 3 consists of patients who have less severe injuries and are not in immediate danger; they can wait longer for treatment. Class 4 patients are those who are unlikely to survive, again allowing for a focus on those who can possibly be saved. Thus, prioritizing Class 2 clients is essential in a mass casualty to stabilize as many individuals as possible, while the focus still remains on those most critically injured.
