what is REM and what is used to submit? -CORRECTANSWER Risk Event
Management and unsafe condition, near miss, and an adverse event
Sterile means -CORRECTANSWER free of all living microorganisms and spores
clean means -CORRECTANSWER not sterile, but disinfected such as a clean dialysis
chair
contaminated means -CORRECTANSWER that a sterile or clean item has come in
contact with non-sterile object
dirty means -CORRECTANSWER neither sterile or clean, but visibly contaminated
Alcohol-bases hand rubs must contain -CORRECTANSWER 60-95% ethyl alcohol,
isopropyl alcohol, or a combination of both
How long should you wash your hands for? -CORRECTANSWER 20 seconds
PPE includes what? -CORRECTANSWER gloves, gowns, masks, protective eye gear
,environmental surfaces are cleaned with appropriate disinfectant such as a bleach
solution -CORRECTANSWER 1:100 one part bleach and 99 part water
for visible blood or gross blood spills, a ______ bleach solution must be utilized -
CORRECTANSWER 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 -CORRECTANSWER antibody positive (immune)
patients
Although dialysis is a complex procedure, it is based on simple principles -
CORRECTANSWER use of a semipermeable membrane, diffusion, ultrafiltration,
convection, and osmosis
what are the 3 treatment goals to achieve in dialysis? -CORRECTANSWER 1. Remove
waste from the blood
2.remove excess water from the blood
3. balance blood electrolytes
,semipermeable membrane -CORRECTANSWER 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 -CORRECTANSWER artificial kidney and
blood site and dialysate site
what happens if the blood site and dialysate site mix? -CORRECTANSWER = blood
leak
what is dialysate (3 things)? -CORRECTANSWER RO water, acid bath, and
bicarbonate
what is an extracorporeal circuit? -CORRECTANSWER bloodline, saline, and
dialyzer=set up
What is diffusion? -CORRECTANSWER 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? -CORRECTANSWER removes water from the blood by pushing
it across the semipermeable membrane
, What is convection? -CORRECTANSWER or solute drag is when solutes move with the
water across the semipermeable membrane.
What is osmosis? -CORRECTANSWER 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? -CORRECTANSWER 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? -
CORRECTANSWER less than or equal to 0.5ppm
What is strikethrough? -CORRECTANSWER 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? -CORRECTANSWER
sodium chloride 0.9% (normal saline)
what is proportioned dialysate? -CORRECTANSWER even amounts of RO water, acid
bath and bicarbonate
