Advice for SNF nursing

I went through a mental health crisis and have found myself in a rut between jobs. My orientation starts next week; however, if I don't get money quickly, my electricity will be turned off before I get my first paycheck. I can work at an SNF through an agency and be paid. I only have hospital experience as a nurse (RN), and timid. I am very good at multitasking and staying organized. I'm aware of the patient load that are at SNFs, etc. I'm most concerned about using PPC to figure out everything, as I have only ever been on EPIC and Cerner.

What to look for and/or do throughout the shift besides meds/treatments/sugar checks

Any helpful tips would be greatly appreciated.

This is the only option I have right now. Please don't tell me I shouldn't; just help me with the how. Somehow, my last check of $900 at the beginning of August disqualifies me from getting any type of low-income assistance.
