You could check out the following site: http://www.lpn-to-rn.net/blog/2009/100-inspirational-and-educational-videos-for-nurses/
It is primarily an American based website but has some inspiring material.
A good place to also check, if you have not done so already, is your university library – you may find a variety of documentaries/educational DVDs relevant to nursing.
I can't remember the link off the top of my head, I'd have to search through past posts, but go on you tube and type in a world without Nurses, by the Australian Nursing union.
