Acute Renal Failure/Acute Kidney Injury Flashcards
cause of pre-renal failure
fluid volume defecit
cause of intra-renal failure
crush injuries/intense physical activity
nephrotoxic drugs
blood transfusion
rhabdomyolysis can be caused by what
intense physical activity
vancomycin, gentamicin, rifampin, sulfa based drugs, NSAIDS, ACE inhibitors all examples of what
nephrotoxic drugs
cause of post-renal failure
renal obstructions
what type of renal failure causes damage inside the kidney
intra-renal failure
phase 1 of ARF
no sxs
phase 2 of ARF
decreased renal fxn with or without decreased urinary output–overloaded with fluid
phase 3 of ARF
diuresis
phase 4 of ARF
recovery
phase 2 of ARF is AKA
overload state
start of phase 1 is from what to what
start of initial factors (risk factors) to the onset of GU sxs
in what phase may you see Kussmaul’s
phase 2
phosphorus and ____ have an inverse relationship
calcium
goal in phase 1
prevent further issues
goal in phase 2
control fluid-pt is overloaded
how to reduce metabolic rate in phase 2
bedrest
large amts of urine lead to a ____ specific gravity
decreased
what must you check before giving lasix
BUN
2 meds given for hyperkalemia
kayexalate & D50/insulin (pushes K out of cell so it can’t be used)
role of phosphate binders
make sure phosphate isn’t absorbed just passed thru stool
what can you give with K that helps it work better
magnesium
look dehydrated in this phase
phase 3
what does dopamine do in renal patients with decreased BP and renal perfusion
dilates renal vessels and increases blood flow to kidneys–constricts periphery leading to an increased BP
in order to get hemodialysis or continuous venovenous hemofiltration your GFR must be below what
15
