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
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
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
The warmer the dialysate is (closer to 38 degrees)
the quicker the _____ transfer/diffuse across the
semipermeable membrane. - ....ANSWER...solutes
Why do we not want to use warmer dialysate? -
....ANSWER...Because it can cause the patient's blood
pressure to drop
By staying away from warmer dialysate, the doctor
is trading off more diffusion of solutes for more
stable __________. - ....ANSWER...blood pressure
If you run the dialysate cooler, closer to 35.0 Celsius,
you slow diffusion and run the risk of some of those
fibers _______ because of how cold the blood is. -
....ANSWER...clotting
The higher pressure on the blood side of the dialyzer
forces the excess fluid out of the bloodstream into
the _________ compartment. - ....ANSWER...dialysate
