Flashcards in Chronic Kidney Dz Deck (10):
1

what is a normal GFR?

125 mL/min

2

What does serum concentration represent?

ration of production to elimination. In steady state, production=elimination

3

why does creatinine filtration increase as GFR declines? How does this affect serum creatinine in early stages of CKD?

enhanced effect of secretion. It attenuates the rise in serum creatinine.

4

What variables are in the GFR formulas?

creatinine, gender, age, ethnicity, albumin

5

How does the reliability of GFR equations change with GFR?

less reliable as GFR increases

6

definition of CKD

decreased kidney fxn for three months. GFR30

7

Which usually comes first: proteinuria or reduced GFR?

proteinuria

8

How is CKD related to peripheral vascular dz?

pro-inflammatory state, alterations in Ca and Pi.

9

what is the formula for albuminuria in a 24 hr period?

urine albumin divided by urine creatinine. Gives you grams of albumin in 24 hrs.

10

what is normal daily creatinine production

~1g/day
