Final answer:
A paramedic should notify law enforcement and document observations when they have reason to believe a child is in need of protection.
Step-by-step explanation:
When a paramedic has reasonable grounds to believe that the patient is a child in need of protection, they should undertake two critical actions. Firstly, they are to notify law enforcement or the appropriate child protective services immediately to report their suspicions. This is essential in initiating an investigation and to safeguard the child from potential harm. Secondly the paramedic must document their observations meticulously.
This includes recording any signs of abuse or neglect they have witnessed, the child's state and any statements made by the child or others present that may be pertinent to the case.
