I was an LPN back home, worked night shift where we would have 1 RN, 2 LPNs and 2-4 NAs for 45 patients. Half of the ward was general medicine, other half cardiac rehab (patients coming out of CCU came up here), so it could be a very busy ward. Day shifts weren't much better, they might have 2 RNs and 3 LPNs. Here, I'm a nursing student (adult branch) and so far on my placements the staffing levels haven't been too bad. At the moment I'm working on a trauma orthopaedic ward and there is usually 1 qualified nurse and 2 NA for 6 or 7 patients, if someone calls in sick at the last minute and its not possible for the bank or an agency to supply extra help, then we might have 1 RN for 12 patients and 1 RN will be ward co-ordinator, this seems to work quite well.
We have a pretty good Trust here in the southwest, so like others have said, it just depends on where you live.
