HemoDialysis Bonnet Exam Questions
and Answers
Osmosis - ANS-movement of fluid across a semipermeable membrane from an area of
lower concentration to higher concentration
Diffusion - ANS-movement of dissolved particles across a semipermeable membrane
from an area of higher concentration to lower concentration
Ultrafiltration - ANS-water is removed from blood because there is pressure gradient
across the membrane
Ultrafiltration Rate - ANS-The rate at which fluid moves from blood into the dialysate
through the semipermeable membrane
Calculation for Ultraflitration rate - ANS-dividing the amount of fluid to be removed by
the minutes of tx time
Transmembrane Pressure (TMP) - ANS-The pressure across the dialyzer
membrane(Blood compartment plus dialysate compartment pressure)
In dialyzer reprocessing this chemical is used for disenfection - ANS-Paracetic Acid
Amount of time water must stay in contact with charcoal in carbon tanks in order to
allow chlorine and chlormaines to be removed - ANS-Empty Bed Contact Time
Minimum number of minutes of contact time in carbon tanks - ANS-10 or 5 in each tank
Diabetes - ANS-Number one cause for CKD
Intrarenal Failure - ANS-Renal failure due to injury to the kidneys
Example of Intrarenal failure - ANS-Blow to kidneys, drug/poison, glomeruolnephritis
Postrenal Failure - ANS-when a blockage causes urine to back up and harm the
kidneys
Example of Postrenal failure - ANS-Enlarged prostate, Stones, Kinked Ureter
Prerenal failure - ANS-when kidneys dont get enough blood
, Example of Prerenal failure - ANS-Trauma Severe dehydration, heart disease
Two hormones the kidneys produce - ANS-Erythroprotein, Calcitriol
Erythropoietin - ANS-triggers bone marrow to make red blood cells
Calcitriol - ANS-Controls the balance of calcium/phosphorus
Location of the kidneys - ANS-In the back of the body above the waste
Size and weight of the kidneys - ANS-the size of a fist, and 5 oz
The dialyzers semipermeable membrane - ANS-alows some substances such as
wastes and excess water out but keeps others such as blood in
Access for pd is through a - ANS-catheter
where is the catheter placed in a pd pt - ANS-abdomen
what acts as a filter in pd - ANS-lining of the abdomen
Dialysis Disequilibrium Syndrome - ANS-caused by the rapid removal of urea during
hemodialysis;
Dialysis Disequilibrium Syndrome Signs/Symptoms - ANS-Headache, blurred vision,
Restlessness, confused, tremors, convulsions, seizures, coma, death
Back flow prevention device - ANS-Stops water from the tx system from flowing back
into the feed water
Large Amounts of aluminum in water can cause - ANS-Bone Disease
How often should the ro operating parameters be checked - ANS-Daily
What is added to municipal water supply to make it clearer - ANS-alum
Depthflitration - ANS-measuring pressure before and after filter
water softner - ANS-softens hard water by taking out some of the magnesium and
calcium that form the scale
booster pump - ANS-used to increase water flow or pressure
Carbon Tank - ANS-Contains granular activated charcoal that abosrobs low molecular
weight from particles
