(Ans - remove catheters as early as possible to prevent infection as it can
spread
s/s of acute kidney injury (AKI)
(Ans - low urine output, concentrated urine, low GFR, high BUN/CRE,
sudden reduction in kidney function
3 Causes of AKI
(Ans - Prerenal, intrarenal, postrenal
explain pre renal causes of AKI
(Ans - disruption in renal perfusion and blood flow. It can cause low blood
pressure, low blood volume, heart failure, renal artery obstruction, fever,
vomiting, diarrhea, burns that lead to dehydration, Drugs such as ACE
inhibitors or angiotensin 2 blockers, NSAIDs that can drop the blood
pressure or cause bleeding
Explain intrarenal causes of AKI
(Ans - damage or disruptions within the kidney blood vessels, tubules, or
glomeruli. It can cause reduced blood supply within the kidneys, toxic injury
with medications, chemo, and contrast medias, renal inflammation, or
prolonged prostate/ stones/ in the post renal stage
