Renal Flashcards
Loop of Henley
Concentrated and dilutes urine
Proximal tubule
Reabsorbs
Distal convoluted tubule
Site of adh control
Arf
Less than 400ml in 24hrs
Prerenal
Hypo perfusion
Renal Arf
Kidney damage acute tubular necrosis
Pre renal urinary sodium
Sodium less than 20
Renal stage sodium level
40-100
Pre renal bun:creat
20:1
Renal fx bun:creat ratio
10:1
Fluid and LASix increases uop in
Pre renal failure
Hyper kalemia symptoms
Muscle weakness EKG changes
Treat hyperkalia
Calcium chliride(if EKG changes)
Insulin and glucose
Bicarbonate
Kayexelate
Acute tubular necrosis caused by
Ischemia and nephrotic ivory
Ischemic causes of atn
Hemorrhage Burns Sepsis Heart failure Transfusion reactions
Nephrotic ivory causes of Atn
Heavy metals Meds Street drugs Rhabdomyalosis Radioactive dye
Oliguric stage
10-17 days
Increased bun creat k
Fluid overload chf
Peritoneal dialysis
Polyuric stage
2 weeks - 3months
Increased bun creat
Low k
Fluid depleted
Recovery stage
3months-1year
Pray the kidneys regenerate
