Correct answer: E — Refer urgently for assessment of digoxin toxicity and electrolytes

Visual disturbance, nausea and confusion are classical features of possible digoxin toxicity. Dehydration, renal impairment and hypokalaemia from diuretics can increase risk. Urgent clinical review and blood tests are needed, including renal function, electrolytes and digoxin concentration when indicated. Symptomatic treatment alone would be unsafe.
