|
Diuresis Period
|
1. Urine output 4-5 L/day
2. Large fluid and electrolyte loss – monitor for hyponatremia, hypokalemia, hypovolemia and hypotension : Na+ and K+ loss in urine 3. High urine output r/t osmotic diuresis from high urea concentrate in the glomerular filtrate and the inability of the tubules to concentrate the urine. (dilute : reflected in low specific gravity) 4. Kidneys can excrete wastes, but not concentrate urine. 5. Uremia present (AEB low creatinine clearance, elevated serum creatinine and BUN) 6. Lasts 1 – 3 weeks |
|
Recovery Period
|
1. Begins when the GFR increases; s/s could occur within 1-2 weeks of this phase; however renal function may take a year to stabilize.
2. Client begins to return to normal levels of activity (decreased BUN) 3. Residual renal insufficiency may be evident 4. Increased mental and physical activity 5. Renal function may continue to improve for up to 12 months after oliguric ARF began 6. Renal function may never return to pre-illness level of functioning |
