Final answer:
After calling 9-1-1, you should apply direct pressure to the wound on the child's head and keep them calm and lying down. It is important to wait for EMS to arrive for further care and transport to the hospital.
Step-by-step explanation:
After calling 9-1-1 for immediate medical help, the first step you should take is to apply direct pressure to the wound on the back of the child's head. This can be done by using a clean cloth or pad and pressing firmly on the wound to slow down the bleeding.
It is important to keep the child calm and lying down to prevent further injury and minimize blood loss. If the bleeding does not stop, you can continue to apply more pressure or replace the cloth with a clean one.
While waiting for emergency medical services (EMS) to arrive, do not apply a tourniquet, as this may cause more harm than good. Once EMS arrives, they will be able to provide the necessary care and transport the child to the hospital for further evaluation and treatment.
