Correct answer: C — Refer urgently for assessment of possible digoxin toxicity

Nausea, visual disturbance and hypokalaemia in a patient taking digoxin are concerning for digoxin toxicity. Thiazide-induced hypokalaemia can increase digoxin toxicity risk. Urgent clinical assessment, ECG, electrolytes and digoxin level interpretation are needed.
