In the management of acute kidney injury, which approach best represents initial management per KDIGO guidelines?

The main idea is that the initial management of acute kidney injury is supportive and focused on preserving kidney perfusion and preventing further injury. KDIGO guidelines emphasize promptly addressing reversible factors: assess and optimize volume status to maintain adequate renal perfusion, avoid nephrotoxins (such as certain drugs and contrast media), and closely monitor and adjust electrolytes and medications that rely on kidney clearance. This approach helps prevent progression and often allows recovery without dialysis. Dialysis is not the first step for all AKI; it’s reserved for specific situations such as severe hyperkalemia, refractory metabolic acidosis, fluid overload not responding to diuretics, or uremic complications. Prophylactic nephrotoxin use would worsen kidney injury, and ignoring electrolyte disturbances can lead to life-threatening abnormalities even if symptoms aren’t yet present.
