Correct answer: D — Do not recommend potassium citrate and refer for assessment of urinary symptoms.

Potassium citrate can increase potassium load, and this patient already has hyperkalaemia risk from CKD, ramipril and spironolactone. Urinary symptoms in an older patient with comorbidity should be assessed appropriately. Supplying potassium-containing products would add avoidable risk.
