The whole point of a specialized unit is for focused care. Pediatric units exist because pediatric patients can have medical issues unique to their population, can respond differently to changes in health, need ped sized equipment., etc. If a facility has specialized units then they should staff and have appropriate backup. In the end, not only is the patient at risk but your professional license is at risk. You have a duty to respond as a prudent professional. If the doc stops returning your calls, use your chain of command. Charge nurse -> House Supervisor -> then depending on your structure...Chief of Pediatrics for your facility. And, chart, chart, chart and then chart some more. I can only use my experience on L&D for examples. It took almost a year before a provider answering my middle of the night call stopped asking, “who else are you working with?”, then talking with them to get confirmation that my info is correct. It did not offend me because I was new and they did not know me. Ultimately, the MD is responsible so they have to trust that the information I am giving them is accurate. The flip side is, when I call an MD in the middle of the night and inform them they need to come now, the act on my request. I have also protected my license by saying ‘no’ to an assignment at the start of a staffing agency shift. I was scheduled to work a staffing agency night shift at a new hospital. When I signed in and met with the charge nurse, I was assigned couplet care. Well, I don’t take care of newborns. I can care for them at delivery and immediately after and even cover for nursery nurse in a delivery in rare circumstances. But a shift of newborns, I said no. The moms were not an issue. Newborns can go bad fast and I don’t have that experience (I have worked nursery and step down NICU at my home hospital paired with a strong RN in the unit). At my staffing shift, they were not happy but changed the assignments to traditional L&D and nursery. It all worked out for them because soon after the change, I was assigned to assess a new rule out labor of a mom who only spoke Spanish.....I’m fluent. Win/win.
