Daily weights, I&O, measure abdominal girth, careful skin care, monitor effect of diuretic therapy.
What is trabeculation?
When the bladder neck get obstructed, the bladder hypertrophies to squeeze the pee out, then it can't compensate anymore and the muscle bundles separate.

Daily weights

Keep pt NPO until bowel sounds/flatus

Mucous in urine is normal

Keep urine acidic to prevent alkaline encrustations
How does the pt take care of a Kock, Mainz, Indiana, or Florida pouch?
These are continent urinary diversions, so they will catheterize q 4-6 hours and wear a small bandage over the stoma. Irrigate daily.
Major risks of bladder sx

Care of an ileal conduit
Change appliance when fluid intake has been restricted for several hours
What is azotemia?
Accumulation of nitrogenous waste products (BUN/creatinine)
What is a prerenal kidney injury?
Something causing a reduction in renal blood flow. There is no damage to the kidney tissue.
What is intrarenal kidney damage?
Direct damage to the kidney tissue.

Ex. nephrotoxins, hemolyzed RBC's, myoglobin released from necrotic muscle cells.
What is the most common cause of intrarenal acute kidney injury?
Acute tubular necrosis.

Risks for ATN include: major surgery, shock, sepsis, blood transfusion reaction, muscle injury, prolonged hypotension, nephrotoxic agents.
What is a postrenal kidney injury?
Some sort of mechanical obstruction in the outflow of the urine.

Bilateral ureteral obstruction leads to hydronephrosis (kidney dilation).
What are the 3 stages of acute kidney failure?
Oliguric, diuretic, recovery
What is the RIFLE classification for staging acute kidney injury?
Risk - serum creatinine x1.5; GFR decreased by 25%, urine output <0.5ml/kg/hr for 6 hr

Injury - Creatinine increased x2; gfr decreased by 50%; urine output <0.5 ml/kg/hr for 12 hour

Failure - Creatinine increased x3; gfr decreased by 75%; urine output <0.3ml/kg/hr for 24 hr of anuria for 12 hr

Loss - persistent acute kidney failure; complete loss of kidney function >4wk

End-stage kidney disease - complete loss of kidney function >3mo
What are the characteristics of urine in the oliguric phase of acute renal failure?
Specific gravity fixed at around 1.010 and osmolality at 300 mOsm/kg, casts, WBCs, RBCs

Same specific gravity and osmolality as for plasma, reflecting tubular damage with a loss of concentrating ability by the kidney.
What is the characteristic of the blood in the oliguric (1st) stage of acute kidney failure?
Metabolic acidosis b/c the kidneys cannot synthesize ammonia which is needed for hydrogen ion excretion.

Damaged tubules can't conserve Na, so hyponatremia.

Can't excrete K, so hyperkalemia.
What happens to respirations in metabolic acidosis?
Kussmaul respirations
What are the characteristics of an EKG in hyperkalemia?
Peaked T waves, widened QRS complex and ST segment depression.
What is the best indicator of kidney damage?

BUN may increase from dehydration, corticosteroids, catabolism resulting from infections/fever/severe in jury/GI bleeds
What neurological sign do you see in the oliguric phase of acute renal injury? (1st phase)
Asterixis from nitrogenous waste accumulation.

(Flapping tremor of hands)
What is the 2nd phase of acute renal failure?
Diuretic phase where hypovolemia and hypotension can occur from massive fluid losses. High urine volume of 3-5L/day is caused by inability of tubules to concentrate the urine. Kidneys have recovered ability to excrete wastes, but not concentrate the urine.
What do you watch for in the diuretic (2nd phase) phase of acute kidney injury? How long does it last?
Hyponatremia, hypokalemia, dehydration. 1-3weeks.
What diagnositic test do you NEVER allow with kidney failure pts?
MRI or MRA. Gadolinium (the contrast agent) causes nephrogenic systemic fibrosis (cutaneous hyperpigmentation, induration and joint contracutres, fibrosis in other organs)
How do you calculate fluid intake in the oliguric phase of acute renal failure?
Losses for past 24hrs + 600ml for insensible losses = fluid allocation for the next day
How do we treat hyperkalemia?
Regular Insulin with glucose (to move K in to the cells)

Sodium Bicarbonate (to correct acidosis and cause a K shift in to cells)

Ca Gluconate (Ca raises threshold for excitation resulting in dysrhythmias)

Dialysis (Most effective)

Kayexalate (1mEq K exchanged/gram of drug. Causes osmotic diarrhea)

Dietary restriction (limit to 40mEq/day)
What are important nursing interventions for acute renal failure?
Daily weights, mouth care (to prevent stomatitis from excess ammonia in the saliva)
