Q

Which type of renal failure has stages and how many stages are there?

A

Chronic renal failure

3 stages

17
Q

What is happening in stage 1 of Chronic renal failure?

A

(1) remaining healthy nephrons compensate by enlarging and taking over the function of the lost nephrons
(2) BUN (blood urea nitrogen test) is kept within normal limits even though up to 75% of nephrons are lost

18
Q

What is happening in stage 2 of Chronic renal failure?

A

(1) kidney can no longer adapt to the loss of nephrons
(2) remaining healthy nephrons cannot handle the urea load
(3) BUN level spikes

19
Q

What is happening in stage 3 of Chronic renal failure?

A

complete renal failure
