I went into home health as a new grad. It depends on the individual. Some people will tell you that you are out there on your own with your patients but that is only partially true. In the physical sense it is only you and the patient and your assessment skills/judgement. But you need to remember that you have a nursing supervisor and physicians at the other end of the phone.
I had a 4 month orientation. I learn quickly and I am never afraid to ask questions. For instance, if I am in a home with a pt and the pt has a dressing i have never seen or some other equipment or diagnoses etc... that i am unfamiliar with, i stop and call. Your nursing supervisor should be receptive. Just be mindful of your limitations. If you get a good orientation you will be okay.
Home care has changed though. Patients are more acute when they come home now than ever before. You will learn a lot in home care. It is not a "fluff job". You will use many skills. At my agency we do wound care, IV therapy, TPN, chemo, phlebotomy, Foley's, trach care, chest tubes etc...etc....Good Luck to you.
