The primary electrolyte in both our blood and the dialysate is... - correct answer sodium
Policy states the conductivity meter should be calibrated when an inaccurate reading is suspected. It
should also be calibrated: - correct answer prior to daily use
When the dialysate sodium level is higher than the level in the blood: - correct answer Diffusion will
cause sodium to move into the blood
The calibration of the conductivity meter should be completed at least... - correct answer daily
Hypernatremia can lead to... - correct answer -Excessive thirst
Decreased weight gains between treatments
Comparing the displayed machine conductivity and your manual conductivity reading with the
Fresenius machine's TCD reading helps to... - correct answer -Assure the machine reading is accurate
- Identify malfunctions of the machine's proportioning system
- Identify malfunctions of the machine's alarm/bypass system
When comparing a manual conductivity reading to
the applicable machine conductivity reading, the difference in
readings should be no greater than.. - correct answer 0.4 mS/cm
If, after recalibrating the conductivity meter and
retesting the machine, the difference between the
manual and applicable machine conductivity remains greater
than 0.4 mS/cm, one should.... - correct answer Remove the machine, tag the machine, and notify
biomed.
, True/false: A manual conductivity reading should not be completed when the machine is in bypass
mode. - correct answer true
True/false: The primary reason for comparing a
manual conductivity with the applicable machine
conductivity is to assure patient safety. - correct answer true
Machine alarm tests are performed: - correct answer Before the initiation of each patient treatment
Once set up for treatment, the recirculation time for a dialyzer should not exceed - correct answer 2
hours
The manual conductivity must match the Fresenius (FMC) dialysis delivery system displayed conductivity
- correct answer +/- 0.4mS
To prepare a 1:100 bleach solution, you would - correct answer Add 1 part of bleach to 99 parts of water
What happens if bleach and peracetic acid are mixed? - correct answer A chemical reaction occurs,
producing toxic chlorine gas
What is the correct procedure for residual bleach testing after chemical disinfection of distribution loops
and equipment fluid pathways? - correct answer Residual bleach testing is performed after bleach
disinfection and prior to use
What is the safe range for dialysate pH? - correct answer Between 6.9 and 7.6
Why is a "strikethrough"‖ of an external pressure transducer protector of concern? - correct answer
Fluid could have entered the machine and contaminated the internal pressure transducer protector
providing a reservoir for microorganisms and causing subsequent patient blood infections
