PCT TEST DAVITA (STUDYGUIDE) EXAM
WITH CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST 2025 - 2026 ALREADY GRADED A+
What is osmosis? - ANSWERS-is the movement of water
across a semipermeable membrane from the side with the
lower solute concentration to the side with the higher
solute concentration
After a chemical disinfection with bleach, how do you verify
that the machine is free of residual bleach before you start
setting up? - ANSWERS-check the fluid from the drain hose
with residual chlorine test strip
What is an acceptable test result when verifying the
absence of residual bleach? - ANSWERS-less than or equal
to 0.5ppm
,Alcohol-bases hand rubs must contain - ANSWERS-60-95%
ethyl alcohol, isopropyl alcohol, or a combination of both
How long should you wash your hands for? - ANSWERS-20
seconds
PPE includes what? - ANSWERS-gloves, gowns, masks,
protective eye gear
environmental surfaces are cleaned with appropriate
disinfectant such as a bleach solution - ANSWERS-1:100 one
part bleach and 99 part water
for visible blood or gross blood spills, a ______ bleach
solution must be utilized - ANSWERS-1:10 1 part bleach and
9 parts water
when preparing patient assignments, teammates who care
for confirmed or suspected hep B surface antigen (HBsAg)
positive patient(s) will only be assigned to simultaneously
care for surface - ANSWERS-antibody positive (immune)
patients
,Although dialysis is a complex procedure, it is based on
simple principles - ANSWERS-use of a semipermeable
membrane, diffusion, ultrafiltration, convection, and
osmosis
what are the 3 treatment goals to achieve in dialysis? -
ANSWERS-1. Remove waste from the blood
2.remove excess water from the blood
3. balance blood electrolytes
semipermeable membrane - ANSWERS-thin sheet of natural
or synthetic material that allows some small particles to
pass through, while blocking other, larger ones.
what is a dialyzer and the 2 compartments - ANSWERS-
artificial kidney and blood site and dialysate site
what happens if the blood site and dialysate site mix? -
ANSWERS-= blood leak
what is dialysate (3 things)? - ANSWERS-RO water, acid
bath, and bicarbonate
, what is an extracorporeal circuit? - ANSWERS-bloodline,
saline, and dialyzer=set up
What is diffusion? - ANSWERS-movement of dissolved
particles across a semipermeable membrane from the side
with the higher concentration to the side with the lower
concentratio n.
What is ultrafiltration? - ANSWERS-removes water from the
blood by pushing it across the semipermeable membrane
What is convection? - ANSWERS-or solute drag is when
solutes move with the water across the semipermeable
membrane.
What is strikethrough? - ANSWERS-Saline rises in transducer
allows for inaccurate readings. The back of transducer is
checked for wet. If wet can contaminate machine. Pull for
bio med.
what is the only fluid we use to prime the blood lines and
dialyze? - ANSWERS-sodium chloride 0.9% (normal saline)
