Correct Answer is B
Explanation
One of the main nursing considerations for a client with osteoarthritis is pain management. Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to provide pain relief and reduce inflammation in individuals with osteoarthritis.
Incorrect responses:
a. Encouraging high-impact exercises is not recommended for clients with osteoarthritis. High-impact activities can cause additional stress on the affected joints and worsen the symptoms.
c. Promoting weight loss is important for overweight or obese clients with osteoarthritis to reduce joint stress. However, it is not applicable for clients with a BMI within the normal range.
d. Advising the client to avoid any form of physical activity is not recommended. Regular low-impact exercises, such as swimming or cycling, are beneficial for individuals with osteoarthritis.
Correct Answer is D
Explanation
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.
