A nurse is caring for a client experiencing a severe flare-up of rheumatoid arthritis. Which of the following pharmacological interventions should the nurse prioritize to manage this client's symptoms?

Rationale: A. Ice is a non-pharmacological intervention that can help reduce pain and swelling, but it does not address the underlying inflammatory process pharmacologically. It is adjunctive rather than a primary treatment for a severe flare. B. Methotrexate is a disease-modifying antirheumatic drug (DMARD) that targets the underlying immune-mediated inflammation in rheumatoid arthritis. During a flare, ensuring that methotrexate is administered as prescribed is essential to control inflammation, prevent joint damage, and slow disease progression, making it the priority pharmacological intervention. C. Physical therapy is beneficial for maintaining joint function and muscle strength, but initiating it during a severe flare can worsen pain and joint inflammation. It is best implemented after the acute inflammation has subsided. D. NSAIDs can provide symptomatic relief of pain and inflammation, but they do not modify disease progression. Using them exclusively without DMARD therapy is insufficient to manage a severe flare and prevent long-term joint damage.
