Correct answer: B — Refer urgently for possible Clostridioides difficile infection

This scenario assesses Antibiotic-associated colitis in a UK pharmacy practice context. Recent broad-spectrum antibiotics and frequent watery diarrhoea raise concern for C. difficile infection. The best answer is Refer urgently for possible Clostridioides difficile infection because it addresses the principal clinical, legal or safety issue before routine supply. The other options are less appropriate because they either miss the key risk, delay necessary review, or would not meet expected BNF, NICE, MEP, MHRA or GPhC practice standards.
