Explain the transport mechanism that plays a role in hemodialysis:
Ultrafiltration - answer Fluid pushed through the semipermeable
membrane (SPM)
Explain the transport mechanism that plays a role in hemodialysis:
Convection - answer Solutes dragged across SPM along with fluid
Explain the transport mechanism that plays a role in hemodialysis:
Diffusion - answer Particles move from area of high concentration to
low concentration
Explain the transport mechanism that plays a role in hemodialysis:
Osmosis - answer Fluid moves from area of low concentration to
high concentration
What are the kidneys' excretory functions? - answer To normalize
electrolytes, remove wastes, provide fluid and acid base balance
How do we replace normal excretory kidney functions? - answer By
normalizing electrolytes through the use of acid concentrate and
providing fluid balance through ultrafiltration
What is the function of the acid concentrate? - answer Provides the
concentration gradient for diffusion and helps normalize
electrolytes
, What is the function of bicarbonate in the dialysate solution? -
answer Buffers the acid concentrate
What is the function of bicarbonate when it diffuses into the
patient's blood? - answer Normalizes body pH
Signs and symptoms of hyperkalemia - answer >5.5 mEq
Extreme muscle weakness, abnormal heart rhythm, and possible
cardiac arrest
Signs and symptoms of hypokalemia - answer <3.5 mEq
Fatigue, muscle weakness, paralysis, respiratory failure, cardiac
instability, arrhythmias, cardiac arrest
Normal blood pH range - answer 7.35-7.45
What are the kidneys' endocrine functions? - answer Renin
secretion, Erythropoietin secretion, Vitamin D activation
How do we replace normal endocrine kidney functions? - answer
Provide medications
How much of normal kidney function is replaced by hemodialysis? -
answer 15%
What is uremia and how does it affect the body? - answer A buildup
of wastes in the blood due to kidney failure and affects all body
systems
What are the most common causes of CKD in the USA? - answer
Diabetes, hypertension, polycystic kidney disease
