FMC RN EXAM QUESTIONS AND
ANSWERS
what happens with dialysate is hypertonic? - Correct Answers -crenation
what happens when dialysate is hypotonic? - Correct Answers -hemolysis
the clean dialysate comes in through the blue hansen. this is opposite the blood. this is
called - Correct Answers -counter current flow
once the dialysate is prepared and the acid and base is right, what is the conductivity is
called - Correct Answers -theoretical conductivity
what is adequacy and how is it measured - Correct Answers -adequacy is how well
dialysis is working to clear waste from the blood. adequacy is measured with kt/v
what is K, t & v in Kt/v - Correct Answers -K: clearance, T: time, V: volume
clearance is what and how is it measured - Correct Answers -the amount of blood that is
cleared of a solute in one minute of Tx. Clearance is measured by KECN (should be
200-300).
KECN (clearance) should not drop by ____% or more - Correct Answers -10%
what does countercurrent flow of the dialysate do? - Correct Answers -maximizes
diffusion and removal of toxins
what things will optimize the adequacy of a dialysis tx? - Correct Answers -Time, BFR,
DRF, volume, dialyzer type & size, priming, heparinization
kt/v has to do with ___ of the blood - Correct Answers -cleaning
ultrafiltration has to do with _____ of the blood - Correct Answers -fluid removal
pre dialysis weight: 73.8
last post weight: 72.0
EDW: 71.5
prime and rinse: 500ml - Correct Answers -AW: pre weight -dry weight: 2.3
Fluid gain: 1.8
target wt: 2.8 (available weight + prime/rinseback )
