Final answer:
To minimize or prevent aggravation of a spinal injury during an emergency move, the EMT should move the patient in the direction of the ambulance.
Step-by-step explanation:
To minimize or prevent aggravation of a spinal injury during an emergency move, the EMT should move the patient in the direction of the ambulance. This is because moving the patient towards the ambulance helps maintain alignment and stability of the spine, reducing the risk of further injury. It is important to avoid any unnecessary movement or twisting of the spine.
