What is the treatment for pre-renal renal failure?

• A. High-dose diuretics
• B. IV contrast administration
• C. Restore volume and function (fluids and foley)
• D. Renal replacement therapy

Answer: (C)

Restoring intravascular volume to improve renal perfusion is the key approach. Pre-renal AKI happens when the kidneys are underperfused, so the priority is to correct the underlying hypovolemia or reduced effective circulating volume with fluids and supportive measures. Give isotonic crystalloids (like normal saline or lactated Ringer’s) and monitor response with urine output, mental status, and vital signs; placing a Foley helps quantify urine output to assess improvement. Once perfusion is restored and the kidneys recover, renal function usually improves quickly if the injury hasn’t progressed. Diuretics are not the initial fix and can worsen volume status, so they’re not the main treatment for this scenario. IV contrast should be avoided or minimized in suspected pre-renal injury because it can further harm renal function. Renal replacement therapy is reserved for severe or refractory cases with complications like severe electrolyte disturbances, acidosis, fluid overload, or persistent kidney failure despite optimization.
