Answer

Renal potassium excretion is increased by the following:

  • Aldosterone
  • WNK1 and WNK4
  • High sodium delivery to the distal tubule (eg, diuretics)
  • High urine flow (eg, osmotic diuresis)
  • High serum potassium level
  • Delivery of negatively charged ions to the distal tubule (eg, bicarbonate)
