It really does vary in regards to how often my days are long - depends on resident acuity, admission, staffing, staff illness/ exhaustion, inservices, orientation, etc. I also am in the rotation for meal manager and on-call nurse (weekends). When I work the floor typically it is part of a shift, but occasionally I have worked an entire shift. More often I provide support to the existing staff so I just work the floor to help things get caught up (change of condition, multiple acutely ill residents/ neb treatments etc).
When I do inservices that nurses attend I schedule times convenient for all shifts. I had been doing 7am, 1pm, and 3pm to hit all the shifts, but have been trialling 1pm, 3pm and 9pm with success. New staff orientation days can also be long because in additional to conducting orientation I also have other things that I need to get accomplished. I also conduct CNA courses as needed so this typically is long days all week when they are in session.
I am lucky though - I was working PRN at this facility the the SDC became available. I had the skills set/ certifications they needed so they sweetened the deal for me to take the job by agreeing to more flexible hours so I can work EMS shifts at my part time employer occasionally.
SDC is really a neat job, I am always learning something new and I still get to interact with the residents.
