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)
,2|Page
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
,3|Page
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
, 4|Page
If the pressure becomes greater on the dialysate side and fibers
are clotting, you will see a _______ TMP. - ANSWER-+ (positive)
If you see a + TMP, the pressure in the dialysate compartment is
now greater than the pressure in the blood compartment. Now
instead of the fluid running out the blood into the dialysate, it
reverses and dialysate is pushed into the blood side of the
dialyzer. What is this called? - ANSWER-backfiltration
Why is backfiltration of the dialyzer a concern? - ANSWER-
dialysate is not sterile and this could harm the patient
Filtration is passive while ultrafiltration uses _____ to squeeze the
fluid out. - ANSWER-pressure
What is the formula for AW (available weight)? - ANSWER-Pre-
dialysis weight - EDW = AW
Pre-dialysis weight - last post weight = ? - ANSWER-fluid gain
