Band 5 job interview with powerpoint presentation.

Hi,
I am a British nurse working within the UK. I have been invited for interview for a Band 5 nurse post in ITU. I am a Registered Sick Children's Nurse, but the ITU is mainly Adult. As part of the interview they want me to give a 5 minute powerpoint presentation on "How I would prove care given is of the highest quality". I really want this job but know that the trust is very clicky and more who you know, than what you know!! I think I want to go with the RCN nursing principles, NMC guidelines, clinical governance and trust policies and guidelines?
Any help would be very appreciated.
Many Thanks
Zoe
