Correct answer: C — Increased digoxin concentration
Amiodarone can increase digoxin levels, requiring monitoring and dose consideration. In this vignette, "Increased digoxin concentration" 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.
