I'm a GP and at the moment in Scotland we seem to have a shortage of practice nurses. This is a branch worth considering, tends to be band F to G (sounds like they've changed as people are talking numbers not letters although many GP practices don't use Agenda for Change) you do chronic disease management, diabetes, COPD, asthma, bloods, health reviews, cryotherapy, immunisations etc. Tends to be daytime only. Has the disadvantage of working alone much of the time which some nurses aren't comfortable with and often your employer is a bunch of GPs.
If you get fed up in hospital and think about practice nursing it's maybe worth doing some courses in your own time like COPD and asthma to get an interview. Things like the Warwick diabetes course can be done when you have a PN job although having that is a very big advantage.
