Which nursing intervention is the most important for a client in the oliguric phase of acute renal failure (ARF)?

Acute kidney failure is a rapid depletion of renal function due to damage to the kidneys. The oliguric time is accompanied by an increase in the serum concentration of substances that glomerular filtration has started to recover.

Limiting fluid intake is most important because since during the oliguric phase of acute renal failure, urine output decreases significantly, leading to fluid overload. Limiting oral and IV fluid intake can prevent fluid overload, and its complications, such as heart failure and pulmonary edema. Restriction of both salt and fluid is crucial.

Limiting fluid intake-rationale: during the oliguric phase of arf, urine output decreases markedly, possibly leading to fluid overload. limiting oral and i.v. fluid intake can prevent fluid overload and its complications, such as heart failure and pulmonary edema. encouraging coughing and deep breathing is important for clients with various respiratory disorders. promoting carbohydrate intake may be helpful in arf but doesnt take precedence over fluid limitation. controlling pain isnt important because arf rarely causes pain.
