Correct answer: B — Use the laxative regularly to prevent opioid-induced constipation

Opioids commonly cause constipation and prophylactic laxatives are usually required. In this vignette, "Use the laxative regularly to prevent opioid-induced constipation" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
