Correct answer: A — Repeat potassium urgently

Haemolysis can cause pseudohyperkalaemia, but a potentially dangerous value cannot simply be ignored. Obtain an urgent carefully collected repeat, assess symptoms, ECG, renal function and contributors, and treat without delay if repeat testing or the clinical picture confirms hyperkalaemia.
