Arterial pressure alarm - answer-AP is the amount of pressure it takes to "pull"
the blood from the access to get it to the dialyzer. Since it is a pull it is negative
pressure. Anything that blocks the pull will increase the pressure.
Causes of hemolysis? - answer--Hypotonic dialysate
-Dialysate temp (too hot)
-kinks in the blood line
-arterial pressure >-250
Conductivity Alarm - answer-If the dialysate falls below or rises above the
conductivity limit, the machine will alarm and go into bypass and the dialysate
is shunted to the drain. If the conductivity is too low, dialysate is dilute
(hypotonic).
Define extracellular - answer-Outside the cell - 30% of body fluids
Define interstitial. - answer-Inbetween the cells- 20% of body fluids
Define intracellular - answer-Inside the cell- 70% of body fluids
,Define intravascular. - answer-Inside the blood vessel- only pulls 10% of all
body fluids at a time
Desired hemoglobin level for dialysis patients? - answer-10-11 (if out of range:
follow algorithm & notify rn)
EBCT - answer-Empty Bed Contact Time
Minimum of 5 minutes in polisher tank
How can we tell whether or not a dialysis treatment is effective? - answer-The
UKM, Kt/v, and URR rely on the Pre and Post BUN being drawn correctly.
How do you prevent TB in the clinic? - answer-Active TB patients cannot
dialyze in clinics. Pt must have 3 consecutive negative sputum cultures before
the can return dialyzing in clinic.
How is TB spread? - answer-Airborne droplets from infected individuals
How long to lab tubes spin for? - answer-15-20 min.
How to prevent air embolism? - answer-1. Test machine prior to use
2. Don't use if it fails
3. Make sure the air detector is armed
4. Keep at least 300 ml NS at all times
, How to prevent hemolysis? - answer-1. Test machines prior to each treatment
(do not use if they fail)
2. Confirm conductivity and pH with Phoenix meter
3. Place bloodlines in line guides
4. Don't run patient with an AP of >-250
5. Troubleshoot: adjust arterial needle, reduce BFR
Hypertonic solution causes what? - answer-Crenation
Hypotonic solution causes what? - answer-Hemolysis
If KECN is decreased, what is a possible cause? - answer-The dialyzer is losing
surface area and clotting can be a potential cause.
Interventions when patient continues to have hypotension? - answer--Readjust
BP cuff
-Place patient in trendelenburg
-Turn UF down or off
-Notify RN and give NS bolus as needed per RN
Interventions when patient goes into severe chest pain or cardiac arrest? -
answer-1. Notify RN
2. Turn the BFR down
3. Turn the UF off
4. RN to administer O2 and possibly nitroglycerine
