Correct answer: B — Check product stability advice and replace if heat exposure may have damaged it

This scenario assesses Insulin heat exposure in a UK pharmacy practice context. Insulin can lose potency after heat exposure even if appearance is unchanged. The best answer is Check product stability advice and replace if heat exposure may have damaged it 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.
