This question separates the acute-attack management of gout from its chronic, urate-lowering management.
- Acute gouty arthritis: needs anti-inflammatory treatment (NSAIDs, colchicine, steroids), not urate-lowering therapy, and starting allopurinol here can even worsen the flare — this is the correct answer.
- Tophi: chronic urate deposits that shrink with sustained allopurinol use, so this is a genuine indication, not the answer.
- Urate nephropathy: prevented and managed with long-term uric acid control, so allopurinol is indicated here too.
- Evidence of bone/joint damage: reflects chronic disease needing ongoing urate control to prevent further damage, so allopurinol is indicated.
Correct answer: Acute gouty arthritis, since it needs anti-inflammatory therapy rather than urate-lowering treatment.
