A nurse is teaching a client who has chronic tophaceous gout about his new prescription for allopurinol. The nurse should explain that the purpose of this medication is to reduce blood levels of which of the following substances?

Choice A reason: Increasing caffeine intake is not recommended for fibromyalgia, as it can exacerbate sleep disturbances and anxiety, common in the condition. Fibromyalgia management focuses on improving sleep, reducing pain, and enhancing function through exercise and medications. This statement reflects misunderstanding, potentially worsening symptoms and hindering effective self-management strategies.

Choice B reason: Taking duloxetine in the morning is reasonable but not the best indicator of fibromyalgia teaching comprehension. Duloxetine, a serotonin-norepinephrine reuptake inhibitor, helps pain and mood but isn’t primarily for energy. This statement shows partial understanding, missing broader management strategies like exercise, which are central to fibromyalgia care.

Choice C reason: Chemotherapy is irrelevant for fibromyalgia, a non-inflammatory pain syndrome, not a malignancy. This statement indicates a significant misunderstanding of fibromyalgia’s nature and treatment, which involves exercise, medications like duloxetine, and cognitive therapies. Expecting a cure via chemotherapy misaligns expectations, delaying effective symptom management and patient education.

Choice D reason: Low-impact aerobics reduce fibromyalgia pain by improving muscle conditioning, circulation, and endorphin release, supported by evidence-based guidelines. This statement reflects understanding of nonpharmacological management, a cornerstone of fibromyalgia treatment, promoting physical function and pain relief, and aligning with comprehensive care to enhance quality of life.

Choice A reason: Probenecid increases uric acid excretion by inhibiting renal reabsorption, used for chronic gout prevention, not acute attacks. It is ineffective for rapid symptom relief, as it does not address inflammation or pain directly. During an acute attack, uricosurics may even worsen symptoms by mobilizing uric acid, making this inappropriate.

Choice B reason: Ibuprofen, an NSAID, reduces inflammation and pain in acute gout but is not specific to gout’s pathophysiology. It provides symptomatic relief but does not target uric acid crystal-induced inflammation as effectively as colchicine. It is often used adjunctively, not as the primary treatment for an acute gout attack.

Choice C reason: Hydrocortisone, a corticosteroid, may be used for gout when NSAIDs or colchicine are contraindicated, reducing inflammation. However, it is not the first-line choice due to systemic side effects like immunosuppression. Colchicine is preferred for its specificity in targeting neutrophil-mediated inflammation in acute gouty arthritis.

Choice D reason: Colchicine is the primary medication for acute gout, inhibiting microtubule polymerization and neutrophil migration, reducing uric acid crystal-induced inflammation. Administered early, it relieves pain and swelling effectively. Its specificity for gout’s pathophysiology makes it the anticipated choice for both preventing and treating acute attacks, minimizing joint damage.
