Which of the following imaging modalities is commonly used to diagnose osteoarthritis?

Osteoarthritis is a degenerative joint disease characterized by the breakdown of joint cartilage, leading to joint pain and stiffness. As the cartilage wears away, the bones may develop small, bony outgrowths called osteophytes.

a. Osteoarthritis is not an autoimmune disease. It is primarily a non-inflammatory condition, and the immune system is not involved in its pathogenesis.
b. Osteoarthritis is not primarily a disease of the synovial membrane. While changes in the synovium can occur in osteoarthritis, the primary pathology is in the articular cartilage.
d. Osteoarthritis is not caused by the deposition of urate crystals. Urate crystal deposition is associated with gout, a different form of arthritis.

Regularly inspecting the client's skin for signs of redness or irritation is crucial to prevent skin breakdown in individuals with osteoarthritis. Since they may have difficulty changing positions frequently due to joint pain, it is essential to identify early signs of pressure sores or skin breakdown and implement appropriate interventions. Providing a firm mattress and using pressure-relieving devices (such as cushions and heel protectors) are recommended to prevent skin breakdown. Encouraging the client to sit or lie in one position for extended periods can lead to pressure ulcers. Applying lotion with a high alcohol content can dry out the skin and increase the risk of skin irritation and breakdown.
