Answer:
Child Protective Services (CPS)
Explanation:
In the United States, if there are suspicions of abuse occurring towards a minor in a household, the CPS should be contacted. In some states, CPS is known as the Department of Children & Family Services.
If the nurse finds that the child's parent behavior towards the disabled child is causing distress and can be classified as neglect and abuse, she should contact the CPS. The CPS would conduct an investigation and remove the child from the custody of the parents until the results of the investigation have clarified the ongoing situation.
