Answer:
apply direct pressure to the injury site while manually stabilizing the stick in her arm
Step-by-step explanation:
Spinal immobilization can generally be explained as the use of adjuncts such as cervical collar, that are being applied to minimize movement of the spinal column.
In this case, since the area where the girl is injured is the forearm, it has no direct connection with the spinal column, this means that, the cervical spinal immobilization is unnecessary.
Therefore, there should be direct application of pressure to the injury site while manually stabilizing the stick in her arm.
