I think Amy is more qualified for poorly babies but nit sure what the difference in tasks would be.
Google suggests As a NNP you will be ordering labs & medications, diagnosing conditions, performing some invasive procedures, evaluating & changing medical treatments (phototherapy and ventilator care) etc all under the supervision of a doctor.
Job role of a nurse: The neonatal nurse stays at the side of their assigned baby, constantly monitoring vital signs, implementing and managing treatments ordered by the doctor or NP. Normally as a neonatal nurse you will have 1 to 2 patients under your care that you are responsible for that day. Some of the things you can expect to do as a neonatal nurse include: surgical care, administering high-risk mediations, resuscitation, administering antibiotics, phototherapy, managing patients that require ventilation support, providing advanced interventions, and providing chronic care management.
