I suggest you evaluate your job prospects based upon your clinical interest and a thorough evaluation of each facility's orientation, on-going education, mentoring and support of new staff, culture of professionalism, nurse to patient ratios, shift availability, pay, benefits, etc.
Either position will potentially prepare you for a long term career in Maternal Child Health as long as you are working and learning in a quality environment.
I hate to be a skeptic, but a new grad opening in L&D raises some red flags, especially if this is a community hospital setting and not a tertiary care center.
L&D is a highly sought-after clinical area. Many hospitals have current staff nurses working other departments on wait-lists for L&D openings, so these positions are rarely available to new grads. Some tertiary care centers have such busy L&D departments that they need large RN staffs and can justify hiring new grads and offering sufficiently long and thorough classroom and clinical orientation. That is rarely the case in small, community hospitals.
A level III NICU on the other hand, typically has a much larger staff than L&D and can absorb and adequately orient new grads much more readily. Managers of these units often prefer new grads over nurses with adult care experience, as it can be difficult for a nurse with adult experience to "unlearn" previous habits that are not compatible with neonatal care, something that isn't an issue for a nurse moving to L&D from a med/surg area.
Please investigate both of these offers carefully. Ask to shadow, or at least talk to some recent hires on both units. Learn the ratio of experienced nurses to new grads on both units. Learn the average tenure of the staff. If there are less than 50% experienced nurses working any given shift (2 years or more on that unit), that is a red flag for frequent turn-over, which will leave you without adequate experienced staff to teach and support you. Ask why this position is open and why they are willing to hire a new grad to fill it. These questions are a bit pointed, but an experienced manager with nothing to hide will be willing to answer and explain.
Good luck to y!ou
