The in-patient dialysis nurses that come to our ICU seem to have a pretty good gig. Granted, they need to know what they're doing, complications from the equipment since they're by themselves etc, but once they start the patient on dialysis, they pretty much just get to sit there for 3 hours watching the machine/chart. You get one patient at a time, so no getting pulled in a million different directions, no families asking you a million questions lol, definitely seems low stress, too. Go for it. I would definitely study all cardio/renal stuff, anything r/t dialysis, peritoneal dialysis/hemo, how to access, complications to watch for, etc. Good luck! Very exciting for you!
