Despite the Availability of Children's Health Insurance Programs (CHIPs), the Nurse

Despite the availability of Children's Health Insurance Programs (CHIPs) , the nurse in a pediatric clinic knows that many eligible children are not enrolled. The nursing intervention that can best help eligible children become enrolled is:

A) Assessment of the details of the family's income and expenditures.
B) Case management to limit costly, unnecessary duplication of services.
C) Advocacy for the child by encouraging the family to investigate its CHIP eligibility.
D) Education of the family about the need for keeping regular well-child visit appointments.
