Correct answer: D — Increased risk of tendon injury

Quinolones have tendon toxicity risk, increased by corticosteroids. In this vignette, "Increased risk of tendon injury" 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.
