Which phase is fourth in the sequence?

Which phase is fourth in the sequence?

• A. Prep for the call
• B. Dispatch
• C. En route to the call
• D. Arrive

Answer: (D)

Understanding EMS call flow helps you see how tasks stack in order. You first prepare for the call, making sure equipment and PPE are ready. Next, dispatch activates the call and provides the details you’ll need. Then you travel to the scene, en route while staying ready for any hazards. Arriving on scene comes after these steps, and that moment is when you perform a scene size-up and begin the initial patient assessment and care. Because arriving occurs after preparation, dispatch, and travel, it is the fourth phase in the sequence.
