Hi renerian,
In our LTC facilities there is one RN, one LPN (LPNs give out routine meds) & 4 NAs for 25 people in the day. There is one RN and 4 NAs for an evening shift. In the night, there is one RN and one NA for 50 residents. IVs are "rare" and usually run at the most - 48 hours for IV antibiotics. No vents. We have no particular "skilled unit" - it is straight geriatric (some younger folk, i.e.: ms, als, parkinsons, etc.) There may one or 2 tube feeds - via pump.
Personally, I don't agree with nurses doing "doubles"(safety issue and burnout) and I am truly against "forced ot".
Hope this helps.
