Unfortunately (or fortunately depending on how you look at) it isn't. Nursing is saddled with increasing patient acuity and decreasing resources, schedule inflexibility, documentation is increasing (it seems as if every other week my nurse managers are rolling out a new paper to fill out to track if xyz is being done...so much for going green), and of course nursing is the dumping ground for all that is wrong. Housekeeping hasn't been around to clean patient rooms, blame the nurse. The patient's TV remote isn't working, blame the nurse. The physician won't make changes to the pain regimen, blame the nurse. Patient satisfaction is below benchmarks, blame nursing. Dietary delivers trays late, blame the nurse. Patient not compliant with treatment plan, blame nursing. The list goes on and on.
With that being said, I don't see an issue with nurses wanting to advance their career beyond the bedside. If current bedside conditions persist it makes sense to seek out other avenues.
