As we have said many times, this limits creativity and flexibility. Now it is free and easy. If you want a quick smoke you just pop off the ward. Nursing students do not need to learn such techniques as you describe anyway, because they will not go near patients apart from supernumerary visits to the ward. I have given a commode once and do not need to do it again because my learning experience is completed' is all that needs to be said politely.
Most nurses specialise after becoming registered.
They go into lecturing, research or management. They call themselves 'practitioners' and generally advise doctors on how patients should be treated. And on this matter I am not happy about nurses being trained by doctors to take over their work, becoming anaesthetists, or stripping veins, for example. We do not expect nurses to become pseudo-doctors, and that is why we ensure their education does not prepare them as such. Angela has told you her concerns that quality nursing is disappearing.
