If the dialysate was prepared by the machine incorrectly with too
much RO and was a hypotonic solution, you would get a ______
conductivity alarm - ANSWER-low
What is the safe range the TCD (Theoretical Conductivity) gives
you? - ANSWER-+/- 0.5
As long as the conductivity is within a +/- 0.5 range of TCD, the
conductivity alarm will not sound because the dialysate is a
_______ solution. - ANSWER-isotonic
If the dialysate is hypertonic, what happens to the RBCs? -
ANSWER-crenation
***Because fluid is pulled out of the cell into the dialysate
because the dialysate has a higher concentration of solutes.
When the too much fluid is pulled out of the red blood cells, it
causes them to shrink (crenation).

If the dialysate is hypotonic, what happens to the RBCs? -
ANSWER-hemolysis
***Because fluid is pulled into the red blood cell, which has
more solutes than the dialysate, and they rupture because they
swell too much (hemolysis).
What is the acceptable value range for testing dialysate
conductivity with a pHoenix meter? - ANSWER-+/- 0.3
How well dialysis is working to remove waste products from the
blood is known as ________. - ANSWER-adequacy
The amount of blood that is completely cleared of a solute in
one minute of treatment given a blood flow rate and dialysate
flow rate is known as ________. - ANSWER-Clearance
What are the 6 elements that affect Clearance? - ANSWER-1.
type of dialyzer (160/180/200/250)
2. treatment time
3. needle size
,3|Page
4. blood/dialysate flow rate
5. anticoagulation (heparinization)
6. temperature
KECN means what? - ANSWER-clearance effective by
conductivity sodium (Na+)
With KECN, we use sodium (Na+) to measure clearance
because it is identical in weight to _______. - ANSWER-urea
Ultrafiltration is filtration under _______. - ANSWER-pressure
Transmembrane pressure (TMP) is the blood side pressure plus
the dialysate side pressure.
True or False - ANSWER-True
How long must you wait after giving the patient heparin before
you can start treatment? - ANSWER-3-5 minutes
, 4|Page
The needle size directly correlates with the _____ rate. -
ANSWER-BFR (blood flow rate)
With a 16 gauge needle, the BFR should not exceed ____. -
ANSWER-350 (300-350 BFR recommended for 16 gauge
needle)
Warmer dialysate will cause the patient's blood pressure to
______. - ANSWER-drop
***Because it causes the blood vessels to relax (widen), which
decreases blood pressure.
Cooler dialysate will cause the patient's blood pressure to
______. - ANSWER-increase
***Because it causes the blood vessels to constrict (narrow),
which increases blood pressure.
In the dialyzer, is the pressure higher on the blood side or the
dialysate side? - ANSWER-blood side
