Reflect on your career prior to going in to be able to apply your experiences appropriately. Difficult family dynamics, unteachable family, pt with advanced anxiety/paranoia/anger as they decline physically. These are all fair game.
I have worked along side the nurses from Amedisys and other same service companies in the area and found the Amedisys nurses more open to work with outside entities and they seemed to love their jobs and their co-workers. They were very happy at work and it showed in the care they gave their patients.
