Daycare questions ??

I'm a 41 year old first time mom and I have a one year old daughter. Until now she has been watched by my sister and a family friend, but the family friend told us suddenly she can no longer watch her so I'm scrambling to find daycare. Can you tell me what would be some good questions to inquire on when trying to find a place? I would like to know if they are trained in cpr and their policy on children that aren't immunized but I'm sure there are questions I haven't even thought of. Advise??
