Which statement is true about Urgent, Priority, and Routine time windows?

• A. Urgent - 2 hours; Priority - 4 hours; Routine - 24 hours
• B. Priority - 4 hours; Urgent - 2 hours; Routine - 24 hours
• C. Routine - 24 hours; Urgent - 2 hours; Priority - 4 hours
• D. Urgent - 2 hours; Routine - 24 hours; Priority - 4 hours

Answer: (A)

In field medical practice, the time windows for Urgent, Priority, and Routine reflect how quickly a casualty should be evacuated or treated based on urgency. Urgent cases are the most time-critical and target action within about 2 hours. Priority cases should be addressed within roughly 4 hours, and Routine cases can wait up to about 24 hours if no immediate threat exists.

The statement that Urgent is 2 hours, Priority is 4 hours, and Routine is 24 hours matches these standard guidelines, making it the best answer. The other options mix or reorder these windows, which would not align with how urgency levels are defined and applied in triage and evacuation planning.
