new to dialysis

hello to all. i am an old nurse (19 yr exp. in L&D) new to dialysis. i am doing chronics in the hosp. i have always working in. 50 beds. i had 80 hr classroom, now in wk 2 of 8 of learning the PCT position. just want to touch base with ya'll & make sure i am on track. sometimes i feel pretty good ( when all is going well), but still feel very inadequate when something goes wrong- of the million things that can go wrong!! still feel very slow, & have to refer to my cheat sheet for putting on & taking off. have already overheard a couple of PCT's commenting on my slowness- it's only wk 2, for crying out loud!!! & my 1st wk of training was disorganized r/t preceptor calling in 2 days, then getting hurt... & on top af that, the pace is way more strenuous than i'm use to- geez, i hurt at the end of the day!! would appreciate knowing i am on track, or if i need to change anything, etc- from you guys who do this for a living. i really do like this- am glad to be learning something new. thanks for your input.
