Acute Renal Failure Flashcards
(9 cards)
What is the definition of acute renal failure (ARF)
The sudden loss of kidney function to excrete toxins and regulate fluid and electrolytes
What are possible causes of ARF
Infection, obstruction, shock
There are three phases say what they are (ARF)
Oliguric, diuretic and recovery
During oliguric phase what should the nurse expect to see clinically ARF
It lasts 1 to 2 weeks. Low urine output less than 400 ml per day, hyperkalemia, hypertension, elevated BUN/creatinine levels, and fluid overload
What two electrolytes will be elevated - ArF
Sodium and phosphate
The diuretic phase is second - what is expected - ARF
Urine output slowly returns, hypokalemia, and hypotension, BUN/Creatinine decreases but stay elevated
What does recovery phase mean - ARF
Kidneys are recovering through a slow process. The GFR increases which allows urine output to increase. The BUN and creatinine return to normal.
Which is the best diet for ARF
Healthy carbs, low protein, and low sodium
ARF CLINICAL priorities
Daily weights
Monitor for azotemia - development of urea in blood
Monitor mental status, as confusion and lethargy are caused by a buildup of toxins in the blood
Insert an indwelling catheter to monitor urine output (doc order needed) accurately
Monitor potassium for hyper/hypokalemia can lead to cardiac issues
