pathophysiology on end stage renal disease

[mjune]

helloo

can you help me with my pathophysiology on end stage renal disease?

like, how is it that there is edema in patients with renal failure. or what really is the picture behind. i dont also understand renin angiotensin system, how does it increase bp. and the antidiuretic hormone, thus it increase or decrease in renal failure. how does it act on the collecting tubules.

can one survive with only one kidney, for how long?

The one thing I remembered when I took my renal test is that ESRD affects every body system. Think about it as far as the edema. Your kidneys are shut down so they can not filter out the toxins of the body and help regulate F and E balances. You retain fluid and what is it called azotemia where the BUN and Creat is high and the Creat clearance is low. This is why people start dialysis with ESRD to filter out the toxin and the help control the fluid and electrolyte balance. Just like you should not give a diuretic if your kidneys are not functioning. And you have to watch the pt fluid intake because they can become hypervolemic due to the kidneys not functioning.

Now I could be wrong because my brain has been on overload this semester. I took two med surg classes and everything is running together. I am sure someone else can explain it better. Do you have a NCLEX Saunders book. When I read out of that one it made a little more sense then reading out of my Med Surg book because it was more straight forward.
