Final answer:
The main purpose of mandatory newborn screening is to recognize and treat newborn disorders early.
Step-by-step explanation:
When teaching parents about mandatory newborn screening, it is important for the nurse to explain that the main purpose is to recognize and treat newborn disorders early.
This screening is crucial because it allows healthcare providers to identify and start treating genetic conditions soon after birth, which can significantly improve outcomes for affected infants. Since the number of conditions tested can vary by state, the goal remains consistent: to ensure early detection and intervention for optimal health outcomes.
