Research Critique

Hi,

I'm a final year nursing student in Scotland, embarking on my last piece of degree work. We have to identify an area of nursing that is of personal and professional interest and conduct a balanced critique of the literature.
I have chosen to write about:

'Should family members be present during resuscitation?'

I was wondering if anyone has any advice. I'm not sure if this is too large a topic and i should perhaps narrow it down. Obviously there is the opportunity to discuss nurses' perspectives, families and also patients as well as ethical considerations, protocols and guidelines etc. The essay has a wordage guidance of 4500.

Any help or advice would be appreciated!

Thanks.
