AKI & CKD Flashcards
Functions of the Kidneys (5)
Maintain fluid & electrolyte balance
Rid the body of water-soluble wastes
Produces erythropoietin- stimulates RBC production
Activates Vitamin D
Produces renin, which helps regulate blood pressure
What is a normal GFR?
> 90 ml/hr
What percentage of a normal GFR is considered renal insufficiency?
25% of normal GFR (25-30ml/hr)
3 classifications of acute kidney injury
pre-renal
intrarenal
post-renal
Pre-renal AKI is caused by
fluid volume loss (Ex: surgery, trauma, dehydration)
Intrarenal AKI is caused by
acute tubular necrosis (Ex: drug overdose, toxic meds, kidney diseases, vascular issue - DMII, HTN)
Post-renal AKI is caused by
obstruction causing cell death
