Unfortunately for you guys, quite a few of the GEPs don't recognise nursing as a health science" degree. That said there are plenty of GEPs and 5 year courses that will consider a graduate from any subject. And especially with all the patient contact you'll get during a nursing degree, you should have a good shot.
As a final thought, Newcastle uni will consider applications from healthcare professionals e.g. paradmedics, nurses etc... and due to the experience you get from these jobs, they waive quite a lot of the entry requirements. Don't know if anywhere else does similar....
