**Core Concept**
Acute renal failure (ARF) following a hemolytic reaction due to incompatible blood transfusion is a severe complication. This condition occurs when the immune system reacts to the transfused blood, leading to the destruction of red blood cells (hemolysis) and subsequent release of intracellular contents into the bloodstream, including hemoglobin, which can cause renal vasoconstriction and acute kidney injury.

**Why the Correct Answer is Right**
The correct management of ARF following a hemolytic reaction involves the use of **furosemide** and **mannitol**. Furosemide is a loop diuretic that helps to increase urine output and reduce the risk of renal failure by preventing the accumulation of toxic substances in the kidneys. Mannitol is an osmotic diuretic that helps to reduce intracranial pressure and prevent further renal damage by increasing the osmotic pressure of the blood and promoting the excretion of water and electrolytes.

**Why Each Wrong Option is Incorrect**
**Option A:** **Hemodialysis** may be necessary in severe cases of ARF, but it is not the initial management of choice for ARF following a hemolytic reaction.
**Option B:** **Blood transfusion** is the cause of the problem, not the solution.
**Option C:** **Corticosteroids** may be used to treat the hemolytic reaction, but they are not the primary treatment for ARF.

**Clinical Pearl / High-Yield Fact**
In patients with hemolytic reactions due to incompatible blood transfusion, the administration of **furosemide** and **mannitol** can help to prevent ARF by promoting diuresis and reducing intracranial pressure.

**Correct Answer:** C. Corticosteroids may be used to treat the hemolytic reaction, but they are not the primary treatment for ARF
