Which of the following factors contributes to the development of osteoarthritis?
Chronic inflammation of the synovial membrane
Hyperactivity of the immune system
Deficiency of collagen in joint cartilage
Excessive physical activity and joint overuse
The Correct Answer is D
Excessive physical activity and joint overuse can contribute to the development of osteoarthritis. Repetitive use and mechanical stress on the joints can lead to cartilage degeneration over time.
a. Osteoarthritis is primarily a non-inflammatory condition. Chronic inflammation of the synovial membrane is more characteristic of other types of arthritis, such as rheumatoid arthritis.
b. Osteoarthritis is not related to hyperactivity of the immune system. It is not an autoimmune disease, and the immune system is not involved in its pathogenesis.
c. Collagen is an essential component of joint cartilage. A deficiency of collagen would weaken the cartilage and contribute to joint degeneration. However, osteoarthritis is not primarily caused by collagen deficiency.

Correct Answer is A
Explanation
Instructing the client to take frequent breaks during activities to rest the affected joints helps reduce stress and prevent worsening of symptoms. Avoiding the use of assistive devices can lead to increased joint strain and pain, so it is essential to encourage their appropriate use. Performing high-impact exercises is not recommended, as they can worsen joint pain and damage. Applying a heating pad for an extended period is not advisable, as it can cause burns and skin irritation.
b. "Avoid using assistive devices to prevent dependency on them." Encouraging the appropriate use of assistive devices is important for clients with osteoarthritis to reduce joint stress during daily activities.
c. "Perform high-impact exercises regularly to strengthen your joints." High-impact exercises can exacerbate joint pain and damage in clients with osteoarthritis. Low-impact exercises are recommended instead.
d. "Apply a heating pad for at least 1 hour to alleviate joint pain." Applying a heating pad for an extended period can cause burns and skin irritation. Using a heating pad for short intervals is appropriate for pain relief.
