The nurse provided education to a client prescribed allopurinol. Which client statement indicates an understanding of the education?

A. "I will decrease the amount of shellfish in my diet.": Shellfish are high in purines, which are metabolized into uric acid. Reducing purine intake supports the uric acid–lowering effect of allopurinol and helps prevent gout flares. Dietary modification is an important adjunct to pharmacologic therapy. B. "I should stop taking allopurinol if I have joint swelling.": Acute gout flares can occur when initiating allopurinol due to shifting uric acid levels. The medication should be continued during flares, with anti-inflammatory agents used for symptom control. Stopping allopurinol can worsen long-term uric acid management. C. "I can expect to get a rash when taking allopurinol.": Rash is a potential adverse effect but is not expected or benign. Allopurinol-associated rash may indicate a serious hypersensitivity reaction requiring immediate evaluation. Clients should report rash promptly rather than anticipate it as normal. D. "I will stop taking ibuprofen when I start allopurinol.": Nonsteroidal anti-inflammatory drugs are often used concurrently to manage acute gout symptoms or prevent flares during initiation of urate-lowering therapy. Discontinuing ibuprofen is not routinely required. NSAIDs may remain part of the treatment plan if tolerated.
