Nursing QUESTION #9307
Question 1
A patient with acute renal failure (ARF) is in the oliguric phase. The nurse should restrict which of the following dietary elements?
  • Carbohydrates
  • Proteins, potassium, sodium, and fluids✔️
  • Fats
  • Vitamin C
Correct Answer Explanation

In the Oliguric Phase of Acute Renal Failure, the kidneys cannot excrete waste products or maintain fluid/electrolyte balance. Dietary restrictions:

RestrictionReason
Protein (0.6–1 g/kg/day)Prevents accumulation of nitrogenous waste (urea, creatinine)
PotassiumPrevents life-threatening hyperkalemia
SodiumPrevents fluid retention and hypertension
FluidsFluid intake = Previous day urine output + 500 mL (insensible losses)
PhosphorusPrevents hyperphosphatemia and renal osteodystrophy

Carbohydrates and fats are encouraged to provide calories and spare protein catabolism.
