By the sounds of it, it all comes down to classification.

If we are saying that a nurse is the highest level and must know how to administer drugs, monitor and do things that a doctor or consultant would do, then yes they do need a very good training. Should that be academic or practical or both.

However the bulk of the work in a ward is related to changing beds, helping patients etc. Does that work need a degree?
Is ther a level in Uk hospitals for this and are they exempt from having to get a degree?
