Correct answer: A — Dissolve each sachet in water and continue regularly until stools soften

Macrogol is an osmotic laxative that works with adequate fluid and regular use. In this vignette, "Dissolve each sachet in water and continue regularly until stools soften" 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.
