Normal Kidney Function vs Hemodialysis

Question 1

Ultrafiltration

Answer 1

Fluid pushed through the semipermeable membrane

Question 2

Convection

Answer 2

Solutes dragged across SPM along with fluid

Question 3

Diffusion

Answer 3

Particles moves from area of high concentration to low

Question 4

Osmosis

Answer 4

Fluid moves from area of low to high concentration

Question 5

What are the kidneys’ excretory functions?

Answer 5

To normalize electrolytes, remove wastes provide fluid and nutrient balance

Question 6

How do we replace normal excretory kidney functions?

Answer 6

By normalizing electrolytes and providing fluid balance through ultrafiltration

Question 7

What is the function of the acid concentrate?

Answer 7

Provides the concentration gradient for diffusion

Question 8

What is the function of bicarbonate in the dialysate solution?

Answer 8

buffers the acid concentrate

Question 9

What is the function of bicarbonate when it diffuses into the patients blood?

Answer 9

Normalizes body PH

Question 10

What are the signs and symptoms of Hyperkalemia (>6.5 mEq )?

Answer 10

extreme muscle weakness, abnormal heart rhythm, and possible cardiac arrest

Question 11

What are the signs and symptoms of Hypokalemia ( <3.5mEq)?

Answer 11

Fatigue, muscle weakness, paralysis, and respiratory failure, cardiac instability, arrhythmias, cardiac arrest

Question 12

What is the normal blood PH range?

Answer 12

7.35-7.45
