A nurse in an emergency department is triaging clients following an external natural disaster. Which of the following clients should the nurse identify to receive care first?

A. A client who has an open fracture of the tibia and reports pain as 5 on a scale of 0 to 10: While the open fracture requires prompt attention to prevent infection and manage pain, it is not immediately life-threatening. This client can be treated after more critical, unstable patients. B. A client who has suspected appendicitis and reports severe lower right abdominal pain: Suspected appendicitis is urgent but not immediately life-threatening unless complications like rupture occur. This client’s condition is lower priority compared to airway or breathing compromise. C. A client who has a penetrating head wound and fixed pupils: Fixed pupils suggest a non-survivable brain injury. In a mass casualty or disaster triage situation, this client is considered expectant and would not receive immediate intervention. D. A client who has flail chest and a respiratory rate of 32/min: Flail chest with increased respiratory rate indicates respiratory compromise and potential hypoxia, which is life-threatening. Airway and breathing take priority, so this client requires immediate intervention to stabilize breathing and prevent rapid deterioration.
