Module 1: Hemodialysis Process, Systems and Devices - DaVita RISE ICHD Study Guide

what is the total proportion of dialysate used at DaVita?

45X

dialysate

mix of specific proportions of acid, bicarbonate, and dialysis quality water

what are the two most frequent physician prescribed potassium strengths of dialysate concentrate used at DaVita?

2.0 K+ and 3.0 K+

which part of the kidney functions similarly to the dialyzer’s semi-permeable membrane to provide filtration and removal of fluids and toxins?

glomerulus

what are the two waste products removed by dialysis that are monitored with monthly labs?

-blood urea nitrogen (BUN)

-creatinine

how often are dialysis machine alarm tests performed?

before the initiation of each patient treatment

what is the safe dialysate pH range?

between 6.9 and 7.6

the manual conductivity value must match + / - 0.4 mS on the ______ and ____

-Fresenius (FMC) 2008K

-K² dialysis delivery system displayed conductivity

the manual conductivity value must match + / - ___ on the Fresenius (FMC) 2008K and K² dialysis delivery system displayed conductivity

0.4 mS

checking independent conductivity is NOT required when using the ____ or ____ models

-Fresenius 2008T

-T BlueStar

why is it important for patient care teammates to know when the water treatment system disinfection was performed?

the end-to-end disinfection process will also introduce the disinfectant solution to the dialysis delivery systems (through their water inlet lines)

following recirculation, how long can a dialyzer and blood lines be set up?

6 hours

why are the dialyzer and blood lines not used for a dialysis treatment once recirculating for longer than 6 hours?

because of the potential for bacterial growth

what is the correct procedure for residual bleach testing after the chemical disinfection of loops and equipment fluid pathways?

residual bleach testing should be performed after bleach disinfection and prior to equipment use
