What is your next step in her management?
She has a worsening AKI with a concerning potassium of 6.1 mmol/L and minimal urine output. Unless something can be done immediately to improve her renal function she is likely to need Renal Replacement Therapy to remove the excess potassium from her blood. Ideally this would be on a renal ward but out of hours or in hospitals without immediate access to nephrology and dialysis, the intensive care team are often contacted to provide RRT. A urinary catheter should be inserted to monitor urine output and a renal tract ultrasound should be performed if not already done so to rule out hydronephrosis.
