I am thinking of applying for acute dialysis and hear that most of the time you work independently and work 10-16+ hours a day, my question is if you hooked up a patient to dialysis can you go to the bathroom? Is there such a thing as a lunch break or bathroom break? Lets say I am working 7a-7p its getting close to 11pm, for that 4 hrs is it considered OT? When you have on call is it usually on the days you are already working or is it on your days that you have off?
