A client with osteoarthritis reports joint pain and stiffness in the knees. Which of the following medications should the nurse expect the healthcare provider to prescribe initially?

X-ray of the joint is the most appropriate diagnostic test to evaluate for osteoarthritis. X-ray can show joint space narrowing, osteophyte formation, and changes in bone density, which are typical findings in osteoarthritis. A complete blood count (CBC) and rheumatoid factor (RF) blood test are used to assess for inflammation and autoimmune markers, respectively, which are more indicative of inflammatory arthritis conditions like rheumatoid arthritis, not osteoarthritis. Synovial fluid analysis is usually performed to assess for infection or inflammation in the joint and may not be as helpful in diagnosing osteoarthritis.

a. A complete blood count (CBC) is used to assess for general health and detect various conditions, but it is not specific to osteoarthritis.
b. A rheumatoid factor (RF) blood test is used to diagnose inflammatory arthritis conditions like rheumatoid arthritis, not osteoarthritis.
d. Synovial fluid analysis is usually performed to assess for infection or inflammation in the joint, but it may not provide definitive evidence of osteoarthritis.

Obesity is a significant risk factor for the development of osteoarthritis, especially in weight-bearing joints such as knees and hips. Excess body weight increases stress on the joints, leading to cartilage damage and joint degeneration.

a. Regular physical activity is generally beneficial for joint health and may help prevent osteoarthritis.
b. Young age is not a risk factor for osteoarthritis; it is more common in older adults.
c. Family history of osteoporosis is not directly linked to osteoarthritis; however, a family history of osteoarthritis itself may increase the risk.
