A 63-year-old man presents to the ED with signs and symptoms of a pneumonia (CURB score 3). He is hypotensive and tachycardic. Blood results confirm he has an AKI with a serum creatinine of 223 umol/L. On direct questioning he reports passing less urine that normal. His urine dipstick is negative for blood and protein.

The AKI in this patient is most likely to be pre-renal in aetiology. True or false?
