A 74 year male was last noted to have a creatinine of 86 micromol/L 2 days prior to presentation. On presentation, his creatinine is 186 micromol/L and his potassium is 7.6 mmol/L.
Is this degree of hyperkalemia expected in this case of acute renal failure?
Name 4 conditions which may present with acute renal failure and severe hyperkalemia (higher than generally expected in acute renal failure). Hint: think of intracellular sources of potassium.
