Sterile means - CORRECT ANSWER -free of all living microorganisms and spores
Clean means - CORRECT ANSWER -not sterile, but disinfected such as a clean dialysis chair
Contaminated means - CORRECT ANSWER -that a sterile or clean item has come in contact with
non-sterile object
Dirty means - CORRECT ANSWER -neither sterile or clean, but visibly contaminated
Alcohol-bases hand rubs must contain - CORRECT ANSWER -60-95% ethyl alcohol, isopropyl
alcohol, or a combination of both
How long should you wash your hands for? - CORRECT ANSWER -20 seconds
PPE includes what? - CORRECT ANSWER -gloves, gowns, masks, protective eye gear
Environmental surfaces are cleaned with appropriate disinfectant such as a bleach solution -
CORRECT ANSWER -1:100 one part bleach and 99 part water
For visible blood or gross blood spills, a ______ bleach solution must be utilized - CORRECT
ANSWER -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 - CORRECT ANSWER -antibody positive (immune) patients
Although dialysis is a complex procedure, it is based on simple principles - CORRECT ANSWER -
use of a semipermeable membrane, diffusion, ultrafiltration, convection, and osmosis
What are the 3 treatment goals to achieve in dialysis? - CORRECT ANSWER -1. Remove waste
from the blood
2.remove excess water from the blood
3. Balance blood electrolytes
Semipermeable membrane - CORRECT ANSWER -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 - CORRECT ANSWER -artificial kidney and blood site
and dialysate site
What happens if the blood site and dialysate site mix? - CORRECT ANSWER -= blood leak
What is dialysate (3 things)? - CORRECT ANSWER -RO water, acid bath, and bicarbonate
What is an extracorporeal circuit? - CORRECT ANSWER -bloodline, saline, and dialyzer=set up
What is diffusion? - CORRECT ANSWER -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? - CORRECT ANSWER -removes water from the blood by pushing it across
the semipermeable membrane
What is convection? - CORRECT ANSWER -or solute drag is when solutes move with the water
across the semipermeable membrane.
What is osmosis? - CORRECT ANSWER -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? - CORRECT ANSWER -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? - CORRECT
ANSWER -less than or equal to 0.5ppm
What is strikethrough? - CORRECT ANSWER -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? - CORRECT ANSWER -sodium
chloride 0.9% (normal saline)
What is proportioned dialysate? - CORRECT ANSWER -even amounts of RO water, acid bath and
bicarbonate
, The manual conductivity must match the dialysis delivery system displayed
conductivity_________ - CORRECT ANSWER -+/- 0.4 ms of the theoretical conductivity (TCD) for
Fresenius delivery systems
The maximum recirculation time after a machine has been set up prior to treatment
Initiation cannot exceed _____ hours. - CORRECT ANSWER -2 hours
What is the rationale for limiting recirculation time? - CORRECT ANSWER -bacterial proliferation
in the extracorporeal circuit may occur
Some blood lines are equipped with external transducer protectors. What is the correct
procedure to be followed once strikethrough of an external transducer protector has occurred?
- CORRECT ANSWER -upon completion of treatment, the delivery system is to be removed from
service and labeled with date, time, description of problem and name the teammate reporting
the problem. The internal transducer protector will be changed by boomed tech. And delivery
system will be disinfected prior to return use
The acceptable range for proportioned dialysate ph is ____________ - CORRECT ANSWER -6.9-
7.6
When are dialysate conductivity and ph testing required to be performed? - CORRECT ANSWER -
prior to initiating a treatment and whenever dialysate concentrate(s) (acid or bicarb) are
changed or replaced during the course of the treatment
If bleach and peracetic acid are mixed, a chemical reaction occurs, producing - CORRECT
ANSWER -toxic chlorine gas
What are the two requirements that must be met prior to initiating system disinfection? -
CORRECT ANSWER -the treatment area must be patient free and no other processes are using
the dialysis quality water
