Answer:
The correct is The Frontier Nursing Service.
Step-by-step explanation:
Obstetric nursing dates back to 1925 in the United States. At that time, Mary Breckenridge developed the Frontier Nursing Service in Kentucky. The program used registered nurses in public health, who had been educated in England, to provide staff for the nursing centers in the Appalachian Mountains. The centers offered family health care services, in addition to childbirth and breastfeeding care to residents in the area.
