A client with osteoarthritis is experiencing severe joint pain and limited mobility. The nurse should recommend which of the following non-pharmacological interventions for pain management?

High-impact exercises can exacerbate joint pain and damage in clients with osteoarthritis. Low-impact exercises are recommended to improve joint flexibility and reduce pain. The other options demonstrate appropriate understanding of osteoarthritis self-management.

a. "I will try to avoid activities that put stress on my affected joints." This statement shows appropriate understanding, as avoiding stress on affected joints is beneficial for clients with osteoarthritis.
b. "I should take my prescribed medications even if my symptoms improve." This statement demonstrates adherence to the prescribed treatment plan, which is important for managing osteoarthritis symptoms.
c. "I will use a heating pad to relieve pain and inflammation in my joints." This statement indicates a correct understanding of using heat therapy to alleviate pain and inflammation in osteoarthritis.

X-ray is the most commonly used diagnostic test to confirm the diagnosis of osteoarthritis. It can show joint space narrowing, osteophyte formation (bony overgrowths), and other changes characteristic of osteoarthritis. Rheumatoid factor (RF) and antinuclear antibody (ANA) blood tests are used to diagnose autoimmune conditions like rheumatoid arthritis, not osteoarthritis. Magnetic resonance imaging (MRI) can provide more detailed images of joint structures, but X-ray is typically the initial diagnostic test for osteoarthritis.

a. Rheumatoid factor (RF) blood test is used to diagnose rheumatoid arthritis, not osteoarthritis.
b. Antinuclear antibody (ANA) blood test is used to diagnose autoimmune disorders such as systemic lupus erythematosus (SLE), not osteoarthritis.
c. Magnetic resonance imaging (MRI) can be helpful in assessing joint structures in more detail, but X-ray is the primary diagnostic test for osteoarthritis.
