I hope I can answer some of your questions. I will have to think back to when I worked in the U.S as a dialysis nurse. I have been working back in Canada for 5 years in dialysis and it is quite different from nursing in the states. Yes, it is quite possible to get hired without experience. You will get trained on the job. I was hired at Fresenius without experience. If you are in a outpt. clinic as I was you will probably be open Mon-Sat. I worked very early days, 12 hour days. The pay was, if I remember, comparable to the pay I made at the hospital. In the outpt. clinic you have techs. I think we had 2 or 3 techs and 2 RN's for a 12 station clinic. Any full time job and completing an MSN program will be challenging! A lot of the next questions all depend on the type of clinic and how much staff there is in your unit. We didn't take call because it was strictly outpt. If dialysis was required they went to the hospital off hours. Where I am now we require an on call nurse from 1 am until 7am. (we are opened from 7 a.m-1 a.m) We also need a Sunday on call. from Sat 1 a.m until Mon 7 a.m which is split into shifts.
I hope I answered some of your questions. Dialysis is really a great place to work. You don't get near as many "codes" but be aware that they do happen. More so where I am now. I work in an acute hospital setting. I still love it. No nights and Sundays off! (just the odd on call. We have 90 nurses working in our program though!!)
Good luck in whatever you decide.
