A patient is in the recovery phase of acute tubular necrosis (ATN). What manifestations should the nurse observe that indicate this phase is progressing as expected?
 
  Select all that apply.
 
  1. elevated serum potassium level
  2. urine output excessive for intake
  3. elevated blood urea nitrogen level
  4. decrease in serum phosphate level
  5. urine output low in relation to intake

Question 2

A patient weighing 209 lbs. is suspected of being in stage 2 of an acute kidney injury. If the nurse uses the standard output of 0.5mL/kg/h,
 
  what is the maximum amount of urine that this patient should produce for 18 hours to confirm this stage of kidney injury?
  Record your answer rounding to the nearest whole number.

Answer to Question 1

Correct Answer: 1, 2, 3
The recovery phase of ATN is characterized by a process of tubule cell repair and regeneration and gradual return of the GFR to normal. Diuresis may occur as the nephrons and GFR recover. Serum potassium, BUN, and serum phosphate levels remain high and may continue to rise in spite of increasing urine output.

Answer to Question 2

Correct Answer: 855 mL
To calculate this patient's weight in kg, divide the weight in lbs. by 2.2. The patient weighs 209 lbs divided by 2.2 = 95 kg. Then use the equation 0.5 mL  95 = 47.5 mL/hr. To calculate the maximum amount of urine that this patient should produce over 18 hours, multiple the hourly amount of 47.5 mL  18 = 855 mL.
