Correct answer: A — Refer urgently for assessment of possible digoxin toxicity and electrolyte disturbance

Digoxin toxicity is more likely with dehydration, renal change and electrolyte disturbance. In this scenario, the pharmacist should prioritise safe supply, appropriate counselling and timely referral or clarification where needed. This is the single best answer because the other options would either delay assessment, ignore a clinically significant risk, or create an unsafe legal or professional outcome.
