DAVITA PCT FINAL EXAM STUDY GUIDE | QUESTIONS
WITH COMPLETE SOLUTIONS | 100% CORRECT.
acceptable result for residual bleach - < 0.5 ppm
Acceptable result for chlorine/chloramine testing - < or equal to 0.1 mg/L
acceptable hardness test result - < 1 grain/gallon
final dialysate conductivity - 13-15.5 mS
final dialysis pH - 6.9-7.6
if dialysis conductivity is too low - hemolysis, bursting of blood cells, cranberry red
blood
if dialysate conductivity is too high - crenation, shriveling of blood cells, dark red blood
alcohol-based hand rubs must contain ___________ - 60-90% ethyl alcohol, isopropyl
alcohol, or both
when washing hands you should lather and wash vigorously for at least _________ -
20 seconds
PPE includes - gowns, face shields, masks, gloves
environmental surfaces are cleaned with ___________ bleach solution - 1:100
visible blood or gross blood spills are cleaned with ________ bleach solution - 1:10;
and soaked with a new disposable towel in 1:10 bleach solution and cleaned a second
time
teammates who care for confirmed or suspected HBsAg positive patients will only be
assigned to care for surface _______________ patients - antigen positive
diffusion - movement of dissolved particles across a semipermeable membrane from
higher concentration to lower concentration
, ultrafiltration - removes water from the blood by pushing it across the semipermeable
membrane, from the blood side within the dialyzer's hollow fibers to the dialysate side
convection - when solutes move with the water across the semipermeable membrane
osmosis - movement of water across a semipermeable membrane from the side with
the lower solute concentration to higher solute concentration
the maximum recirculation time after a machine has been set up prior to recirculation
initiation cannot exceed _________ - 2 hours; longer time can lead to bacterial
proliferation
what is the correct procedure if strikethrough of the external transducer protector has
occurred? - change transducer, flush lines back, send to biomed to be disinfected
the manual conductivity must match the dialysis delivery system displayed conductivity
__________ - +/- 0.4 mS
when are dialysate conductivity and pH testing required to be performed? - before each
patient treatment (after testing, before recirculation)
if bleach and peracetic acid are mixed, a chemical reaction occurs, producing
__________ - toxic chlorine gas
what two requirements must be met prior to initiating system disinfection? - treatment
area must be free of patients and free of dialysis processes
acceptable result for absence of peracetic acid - < or equal to 1 ppm
blending valve - mixes hot and cold water to allow RO to function at most efficient
temperature (77 degrees F)
backflow preventer - prevents pre-treated water and disinfectants from backing up into
the city water supply
booster pump - increases incoming water flow and pressure, maintains water pressure
needed for components operation
multimedia or depth filter - filters out suspended particles like silt and sand in the water
and traps solutes and other substances
