I need a vision

About a month ago I posted regarding questions for an interview that I might get asked. I took the interview and it went well I have been asked something further by this employeer in which I'm applying for a Head Nurse on a 32 bed LTC unit with patients ranging from 72 year old A and O x 3 to 91 year old who doesnt know his/her name.
I've been asked to write a one page essay on what my Vision would be if I was the Head Nurse for this unit.
Can someone help me get an idea of what they are after? A Vision is a goal right? or what should be done, right?
Should my vision for the unit be that of the hospital?
Should my vision be the patients get the care they deserve? and the staff have a high moral?
Help!
