Chronic Renal Failure

Question 1

chronic renal failure

Answer 1

progressive, permanent damage

Question 2

stages

Answer 2

• determined by GFR, urine volume, and azotemia
  1. Diminished Renal Reserve
  2. Renal Insufficiency
  3. Renal Failure

Question 3

diminished renal reserve

Answer 3

• GFR < 50% of normal (normal = 100-120mL/min)
• still adequate for filtration
• no signs of decreased renal fx (kidney has large fx-al reserve)

Question 4

renal insufficiency

Answer 4

GFR between 20-50% (inadequate filtration)

Question 5

renal failure

Answer 5

• GFR < 20%

- GFR < 5% = end stage; kidney will shut down
