How can we measure how well we clean our patients blood? - ---------correct
answer------By measuring the amount of waste in the patients blood before
and after dialysis.
How can you tell if a dialyzer is clotting? - ---------correct answer------Rising
TMP, rising venous pressure, dark blood in dialyzer, and air detector alarms.
, How do you prevent TB in a dialysis clinic? - ---------correct answer------Patients
who have active TB cannot dialyze in a hemodialysis clinic. 3 consecutive (-)
sputum cultures before returning to the clinic
How do you test for small blood leak? - ---------correct answer------Dipping FMS
approved blood leak test strip into dialysate obtained from the outflow
(arterial/red) port.
How is anemia treated? - ---------correct answer------Epogen is a medication
given to stimulate RBC production an keep the patients hemoglobin levels at
an acceptable level.
How is cramping treated? - ---------correct answer------Pressure against
cramping muscle. DO NOT MASSAGE
How is dialysis delivered? - ---------correct answer------The Hemodialysis
Machine.
How is hypertension treated? - ---------correct answer------Dialysis treatment
removes excess fluid which is a contributing factor or hypertension.
