List the four transport mechanisms Ultrafiltration
that play a role in hemodialysis Convection
Diffusion
Osmosis


Explain ultrafiltration in hemodialysis Fluid is pushed through the semipermeable
membrane (SPM). Think: wringing out a wet rag.


Explain convection in hemodialysis Solutes DRAG across the semipermeable
membrane with fluid

, Explain diffusion in hemodialysis PARTICLES move from HIGH concentration to
LOW concentration


Explain osmosis in hemodialysis FLUID moves LOW concentration to HIGH
concentration


What are the kidneys' excretory To normalize electrolytes, remove wastes, provide
functions? fluid and nutrient balance


How do we replace normal By using acid concentrate to help normalize
excretory kidney functions? electrolytes and ultrafiltration to provide fluid
balance


What is the function of acid Provides the concentration gradient for diffusion
concentrate and helps normalize electrolytes


What is the function of bicarbonate It buffers the acid concentrate
in the dialysate solution?


What is the function of bicarbonate It normalizes body pH
when it diffuses into the patient's
blood?


What are some S/Sx of K+ > 6.5 mEq
hyperkalemia? extreme muscle weakness, dysrhythmias, and
possible cardiac arrest


What are some S/Sx of K+ < 3.5 mEq
hypokalemia? fatigue, muscle weakness, paralysis, resp. failure,
cardiac instability, arrhythmias, cardiac arrest
