CHT Bonent Exam (New 2026/ 2027
Update) Questions & Answers {Grade A}
100% Correct (Verified Solutions)
Babies born to women on dialysis have - Correct answer 50% survival rate
Patient education steps include - Correct answer Readiness, need, language, repeat,
belief
Solution - Correct answer mixture of solvent and solute
Solvent - Correct answer Fluid
Solute - Correct answer A substance that is dissolved in a solution.
What is the solution, solvent, and solute in dialysis? - Correct answer Solution-
dialysate
Solvent-treated water
Solute-electrolytes and glucose
,Why do we match the electrolytes in dialsyate closely to patients blood? - Correct
answer To avoid loss of electrolytes during tx
Solubility - Correct answer How well a solute fully dissolved in a solvent
Concentraion - Correct answer Only so much solute can be dissolved before a solvent
become saturated (full)
Why do we use 2 concentrates to make dialysate - Correct answer To avoid the
formation of solids
Acid concentrate - Correct answer Has calcium and magnesium
Bicarbonate concentrate - Correct answer Has bicarb and carbonate
When water has bicarb and carbonate.... - Correct answer We can't add calcium and
magnesium without forming solids so we dilute with water
,Percipitate - Correct answer Solids that can form when some solutes mix , we make
dialysate out of 2 solutions to avoid this
Diffusion - Correct answer Solutes move across membrane till both sides are equal
when to solutions come in contact with a semipermeable membrane.
In dialysis waste diffuses across membrane to dialysate
Gradient - Correct answer The difference between the 2 concentrations in both sides
of the semipermeable membrane.
We use in dialysis to force waste out of blood, and to balance electrolytes
Hypotonic - Correct answer Lower solutes than blood
Isotonic - Correct answer Same solutes as blood
Hypertonic - Correct answer More solute than blood
, Factors that affect diffusion - Correct answer Size of solute-smaller move more
quickly and easily
Temperature-Warmer moves faster and fluids diffuse faster
# and size of dialyzer pores= larger pores faster diffusion
Surface area-larger more diffusion
The direction of flow- of blood and dialysate are flowing in opposite direction, diffusion
is higher
Countercurrent flow - Correct answer Blood and dialysate flow in opposite directions
makin concentration gradient high
Concurrent flow - Correct answer Dialysate and blood flow in same direction
Makes dialysis 15% less effective. Can be used in children to reduce symptoms
Osmosis - Correct answer The movement of fluid to a higher solute contraction
Used to pull water out of blood
