A Neonatal Nurse Practitioner (NNP-BC) is an advanced practice registered nurse (APRN) who specializes in the care of newborns, particularly those who are premature, ill, or requiring specialized medical attention. NNPs are certified through a board certification process, ensuring they have the necessary skills and knowledge to provide high-quality care in neonatal intensive care units (NICUs), delivery rooms, and other healthcare settings that cater to neonates.
