A client with gouty arthritis reports tenderness and swelling of the right ankle and great toe. The nurse observes the area of inflammation extends above the ankle area. The client receives prescriptions for colchicine and indomethacin. Which instruction should the nurse include in the discharge teaching?

A. Limit use of mobility equipment to avoid muscle atrophy: Clients with gouty arthritis need to protect affected joints during acute inflammation, not limit mobility aids. Using assistive devices when necessary prevents further strain and reduces pain. B. Massage joints to relax muscles and decrease pain: Massaging inflamed joints increases irritation, worsens pain, and may trigger further inflammatory response. Gout-affected joints are extremely sensitive, making massage contraindicated. C. Return for periodic liver function studies: Both colchicine and indomethacin are metabolized by the liver and may cause hepatotoxicity with long-term use. Monitoring liver function is an important part of safe management and should be reinforced in teaching. D. Substitute natural fruit juices for carbonated drinks: While hydration is important in gout management, fruit juices high in fructose can increase uric acid levels and worsen symptoms. The recommendation is to increase water intake rather than replace soda with fruit juices.
