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, sal ine, 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 ANS WER 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 o f 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 th an 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 cond uctivity 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 equip ped 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 serv ice 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 pro portioned 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 syst em disinfection? - CORRECT ANSWER the treatment area must be patient free and no other processes are using the dialysis quality water What must be done to indicate the presence of disinfectant in the machines during system disinfection? - CORRECT ANSWER notification of the type of disinfection is prominently displaced on each delivery system
