A client with a history of gout presents to the clinic with an inflamed left knee. The client reports the knee is extremely painful to touch for the second time in 6 months. The healthcare provider prescribes colchicine and ibuprofen. Which instruction should the nurse include in the discharge teaching?

Rationale: A. Decrease consumption of red meat and most seafood: These foods are high in purines, which are metabolized into uric acid. Reducing purine intake helps lower uric acid levels, minimizing the frequency and severity of gout flares. B. Support joints in an extended position while resting: Keeping joints in an extended position may worsen discomfort and inflammation. During acute attacks, joints should be rested in a slightly flexed, supported position to relieve pressure. C. Massage joints to relax muscles and decrease pain: Massage of an inflamed joint during a gout attack can increase pain and inflammation. The affected area is usually extremely sensitive and should be protected, not manipulated. D. Replace dietary table salt with salt substitutes: Salt substitutes often contain potassium, which can interact with medications like NSAIDs or ACE inhibitors. This recommendation is unrelated to gout management.
