minutes
At what point during treatment will diffusion cease to occur? - ANSWER>>Continue until
the concentration of each electrolyte found in the patient’s blood is equal to the electrolyte
concentrating in the dialysate.
Circulation - ANSWER>>BFR = 300/400
DFR = 500

rupture or burst, releasing cell contents, including potassium and haemoglobin into the blood.
Dialysis surfaces must be disinfected with what solution? - ANSWER>>1:100 bleach
solution
,During initiation of treatment, when is the lab work drawn? - ANSWER>>Prior to
administering heparin

, How can we measure how well we clean our patients’ blood? - ANSWER>>By measuring
the amount of waste in the patient’s blood before and after dialysis.
How can you tell if a dialyzer is clotting? - ANSWER>>Rising TMP, rising venous pressure,
dark blood in dialyzer, and air detector alarms.
How do you prevent TB in a dialysis clinic? - ANSWER>>Patients who have active TB
cannot dialyze in a haemodialysis clinic. 3 consecutive (-) sputum cultures before returning to
the clinic
How do you test for small blood leak? - ANSWER>>Dipping FMS approved blood leak test
strip into dialysate obtained from the outflow (arterial/red) port.
How is anaemia treated? - ANSWER>>Epogen is a medication given to stimulate RBC
production an keep the patients haemoglobin levels at an acceptable level.
How is cramping treated? - ANSWER>>Pressure against cramping muscle. DO NOT
MASSAGE
How is dialysis delivered? - ANSWER>>The Haemodialysis Machine.
How is hypertension treated? - ANSWER>>Dialysis treatment removes excess fluid which is
a contributing factor or hypertension. Antihypertensive medications may be prescribed for
patients
How is Tuberculosis spread? - ANSWER>>Droplet of nuclei produced from infected
individuals when they cough, sneeze, speak, or sing
