Just hired as Administrative RN at Assisted Living

I'm new to the site and need some advice. I've been reading the posts and you all seem very knowledgeable and experienced, so maybe you can help! I've just accepted a position as the only RN in an Assisted Living community. I am coming from an Acute Care, hospital background with 3 years of RN experince and 7 years total hospital experience. I took this position because I am interested in management and leadership. The salary was also quite nice. The CEO offered this job with the incentive of rapidly moving up in the company.

Here's my issues. The facility has had some problems and is changing management to correct them. There is a new Facility Director, who has lots of experience and seems very committed to turning the place around. They are letting go of the current RN, and hiring me to make the necessary changes and put systems in place to help the facility. It is a smaller community, only about 30 residents. My first priority is going to be the medication system, since there are "Medication Techs" handing out meds under my license. What else should I be concerned with? What are some issues I might encounter in this role and any advice on how to handle them? Any other advice you have for a newbie to the nursing management world would be greatly appriciated!!
