I just finished my first week of orientation on a 19 chair hospital HD unit - most of the patients are outpatient, but some inpatient (I will be learning acute dialysis, but for now just the chronic). We have 10 RNs, 6 LPNs and 2 PCTs, so the nurses do most of the work, including starting/ending runs, assessments, dressing changes and meds. We do have a team leader to handle most of the orders and phone calls, scheduling, etc. My question is this: is 5 weeks enough orientation to be able to function independently? I'm an experienced surgical RN, but I'm overwhelmed at how much there is to learn, both theory and practice - after 1 week, I still don't feel like I have the hang of the machine, let alone the rest of it. How long is a reasonable orientation?
