Renal Cancer - Med Mx, Surg Mx: Renal artery immobilization may be done, whcih is what?
If you have renal artery thats feeding kidney, they will block and immobilzie the blood supply to the kidney. Kidney will not be fed and will kill the tumor.

Turns every 2 hours, cough/deep breath, DVT prophylaxis.
Renal Cancer - Nursing Mx: When would radiation be considered?
This is typically more for palliative care to keep them comfortable
AKI: What is this?
Rapid loss of renal function due to damage to the kidneys. Some event has caused kidneys to malfunction
AKI: What is the other name for this
ACute renal failure
AKI: What are some events that may cause this?
If patient hypovolemic, hypotensive, kidneys aren’t getting perfused.
AKI: What must you treat first?
Whaetever is causing the kidney injury. If dehydrated, give more water.
AKI - Classifications: What are the three classifications of this?
Prerenal
Intrinsic
Postrenal
AKI - Classifications: What occurs in prerenal?
Marked decrease in renal blood flow
AKI - Classifications: What occurs in intrinsic?
Damage to structures within the kidney
AKI - Classifications: What occurs in postrenal ?
Obsturction of urine outflow from kidney
AKI - Classifications: What may cause prerenal?
Septic, Shock, Vasodilated, Impaired Cardiac Function, Decreased EF.
AKI - Classifications: In prerenal , cause is happening before what?
Before the kidney is affected.
AKI - Classifications: What is happening in Intrinsic?
Damage to glomeruli or kidney tubules.
AKI - Classifications - Intrinsic: What can cause damage to occur?
Antibiotics, Amioglycosides (mycin family)
Contrast for CT.
NSAIDS
Myoglobinurea
AKI - Classifications - Intrinsic: How to treat if this is happening due to an antibiotic?
Take away the antibiotic and give them a different one
AKI - Classifications - Intrinsic: What happens if Creatinine is at 2 and contrast is needed?
Contrast induced neuropathy can occur . This is why we premedicate with extra solution and give bicarb and bicarb solution for the kidneys.

The kidneys
AKI - Classifications - Intrinsic: Tyelonol damages what?
The liver
AKI - Classifications - Intrinsic: Why does Myoglobinurea occur?
When there is a crush injury . Patient is found down and developed rhabomylosis (due to muscle injury. Results form death of muscle fibers). Myoglobin gets released from muscle and plug kidneys
AKI - Classifications - PostRenal: What does this deal with?
Obstruction of urine outflow from kidney. Urine can’t go to bladder or if prostate tissue, backs up the kidney. Backup of urine into kdiney
AKI - Classifications - PostRenal: What can cause this
Kidney stone, BPH, blood clots within ureter,
AKI - Phases: What occurs in first phase?
Initiation phase. What causes the original injury
AKI - Phases: What occurs in the second phase
Oliguria period. <0.5 mL/kg/hr. Decreased urine output
AKI - Phases - 2nd Stage: Decreased urine output leads to what
Increased concentration of potassium, creatinine, uric acid , increase in waste products.
AKI - Phases - 2nd Stage: What issues can occur in patient has high potassium level?
Peak T Wave.
AKI - Phases - 2nd Stage: How can high potassium be treated?
Kayexelate, works by binding to stool and patient poops out potassium. DEcreases concentration.
Insulin
AKI - Phases - 2nd Stage: What does giving insulin for high potassium do for patient?
Forces the potassium back into cell until we can get the potassium down permanently.
Given in emergent siutation.
AKI - Phases - 2nd Stage: What must you do if you give insulin for hyperkalemia?
You have got to give dextrose so you don’t bottom patients glucose out.
AKI - Phases - 3rd Stage: What occurs here?
Diuresis. Gradual increase of urine output and GFR is increasing
AKI - Phases - 3rd Stage: What must you watch out for here?
The patients fluid volume levels

If you are going to be giving nephrotoxic medications, monitor the kidney function.
This includes antibiotics and amioglycosides.
AKI Tx - Prevention: What must you watch out for if patient has contrast?
Contrast induced nephropathy (damage to small blood vessels or to the units in kidneys that clean blood)
