الإجابة: A. Pre-renal AKI

Vomiting and diarrhoea cause hypovolaemia, which lowers effective arterial blood volume and renal perfusion. That is pre-renal AKI: typically a raised BUN:creatinine ratio and FENa <1%, and it reverses with fluids.
- Intrinsic AKI (ATN, AIN, GN) needs damage to the kidney itself. Prolonged prerenal hypoperfusion can progress to ATN, but the picture here is pre-renal.
- Post-renal AKI needs obstruction.
- CKD is not acute.
