A client with osteoarthritis presents with joint pain that worsens with weight-bearing activities and improves with rest. Which of the following clinical manifestations is described?

Osteoarthritis commonly affects the distal finger joints, such as the DIP (distal interphalangeal) and PIP (proximal interphalangeal) joints. This form of osteoarthritis is known as Heberden's and Bouchard's nodes, respectively.

a. Osteoarthritis is not an autoimmune disorder; it is a degenerative joint disease.
b. Unlike rheumatoid arthritis, osteoarthritis is not characterized by joint inflammation and swelling.
d. While osteoarthritis primarily involves synovial joints, it is not limited to these joints.

Obesity is a primary risk factor for the development of osteoarthritis, particularly in weight-bearing joints such as the knees and hips. Excess weight puts increased stress on the joints, leading to cartilage breakdown and the development of osteoarthritis. While age, family history, and a sedentary lifestyle can also contribute to the development of osteoarthritis, obesity is the most significant risk factor.

a. While age over 65 years is a risk factor for osteoarthritis, it is not the primary risk factor. Osteoarthritis can occur at any age, especially if other risk factors are present.
b. Family history of osteoporosis is not a primary risk factor for osteoarthritis. Osteoarthritis and osteoporosis are separate conditions with different risk factors.
c. While a sedentary lifestyle can contribute to the development of osteoarthritis, it is not the primary risk factor. Obesity is a more significant risk factor in this context.
