A nurse is triaging clients following a mass casualty event. Which of the following clients should the nurse assess first?

Choice A reason: A Client Who Has a Small Circular Partial-Thickness Burn of the Left Calf

A small circular partial-thickness burn of the left calf is considered a minor injury in the context of a mass casualty event. This type of injury does not pose an immediate threat to life and can be managed after more critical cases are addressed. In mass casualty triage, patients with minor injuries are often categorized as “green” or “minimal” and are treated last.

Choice B reason: A Client Who Has Severe Respiratory Stridor and a Deviated Trachea

A client with severe respiratory stridor and a deviated trachea should be assessed first. These symptoms indicate a potential airway obstruction, which is a life-threatening condition requiring immediate intervention. In mass casualty triage, patients with compromised airways are given the highest priority and are categorized as “red” or “immediate” because their condition is critical and requires urgent medical attention.

Choice C reason: A Client Who Has a Splinted Open Fracture of the Left Medial Malleolus

A splinted open fracture of the left medial malleolus is a serious injury but not immediately life-threatening if properly splinted. This client would be categorized as “yellow” or “delayed” in mass casualty triage, meaning they require medical attention but can wait until more critical patients are stabilized.

Choice D reason: A Client Who Has a Massive Head Injury and Is Experiencing Seizures

A client with a massive head injury and experiencing seizures is in a critical condition. However, in the context of mass casualty triage, the immediate priority is to secure the airway, breathing, and circulation. While this client is in dire need of medical attention, the presence of severe respiratory stridor and a deviated trachea in another client takes precedence due to the immediate threat to life.
