Flashcards in Chronic Kidney Dz Deck (10):
what is a normal GFR?
What does serum concentration represent?
ration of production to elimination. In steady state, production=elimination
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.
What variables are in the GFR formulas?
creatinine, gender, age, ethnicity, albumin
How does the reliability of GFR equations change with GFR?
less reliable as GFR increases
definition of CKD
decreased kidney fxn for three months. GFR30
Which usually comes first: proteinuria or reduced GFR?
How is CKD related to peripheral vascular dz?
pro-inflammatory state, alterations in Ca and Pi.
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.
