Her left knee also sometimes bothers her. She has taken ibuprofen and tylenol without relief, and the pain is starting to upset her daily routine. On physical examination, the joints of her fingers and wrists are swollen and tender to touch. Her left knee also feels warm. The strength in both hands is reduced but the sensation is intact. On auscultation, the heart sounds are regular and the lungs are clear. Laboratory findings are presented below:Hemoglobin 12.7 gdLHematocrit 37.5 Leukocyte count 5,500mm3Mean corpuscular volume 82.2 μm3Platelet count 190,000mm3Erythrocyte sedimentation rate 45 mmhC-reactive protein 14 mgdLAnti-citrullinated protein antibody 43 normal reference values: 20Which of the following is the most appropriate treatment for this patient?? A: Ibuprofen, B: Hydroxychloroquine, C: Infliximab, D: Methotrexate, E: Etanercept,  <response>: Based on the description of the patients symptoms, including joint pain, morning stiffness, swollen and tender joints, reduced hand strength, and elevated inflammatory markers like ESR and CRP, this patient most likely has rheumatoid arthritis. The positive anti-CCP antibody is also highly specific for RA. The treatment options listed include NSAIDs like ibuprofen, DMARDs like methotrexate and hydroxychloroquine, and biologic agents like infliximab and etanercept. NSAIDs like ibuprofen would only provide symptomatic relief and do not treat the underlying disease process in RA. DMARDs like methotrexate and hydroxychloroquine are considered first-line treatments for RA as they can help slow disease progression. Biologic agents like anti-TNF inhibitors infliximab, etanercept are typically reserved for patients who fail initial DMARD therapy.Based on guidelines, a DMARD like methotrexate or hydroxychloroquine would be the most appropriate first-line treatment choice for this newly diagnosed RA patient.D: Methotrexate
