You get a lot of vents, work with a lot of respiratory therapists so it's good for pulmonary background and the vent experience might make you more attractive for ICU at some other time. You get to see weans that take months (from the vent), going to different types of trachs, decannulated, the journey from life support to talking back and feeding their own selves is pretty amazing.
Also you can get a bit of palliative care experience, as they don't all get better. Some get a lot worse. You have a lot of foleys, rectal tubes, picc lines, central lines, dobhoff and ng tubes, and PEG feeding tubes with various pumps. Very fun, so you do get used to dealing with a lot of stuff hooked up to your patient.
You see more wounds than you can shake a stick at, and get much better with dressing changes. Lots of ostomies as well. Since the patients are more like residents with their long stays, you get to develop your psychosocial skills in dealing with them and their families. Oh, and there is also physical therapy, occupational therapy, speech therapy, and in most places their own wound care nurse. So you have a lot of interdisciplinary stuff going on as well. The workload resembles, ratio-wise in my facility anyhow, a good hospital medical floor ratio. Like I'm used to 4 and can do four. Sometimes it's two, or three, and if everything including a weather disaster happens it can be five. I don't like five but I can do it once in a long while. If you do the ICU rooms it's probably a 2 patient assignment.
All in all I think the biggest challenge with my facility for new grads, would be that they mostly hired experienced nurses with ICU experience and we have this laid back attitude that can get a new grad in trouble if they adopt it while trying to be like their preceptor. So it's good for experience, but insist on something more akin to an apprenticeship than an orientation- like, could you please do 90 days or so, with varying workloads, consistent preceptorship, and I think the new grads should work some shifts opposite what they normally work, if possible, to get a feel for the "other side."
