The healthcare provider is evaluating a client with joint pain and stiffness for possible osteoarthritis. Which of the following physical examination findings is most consistent with 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.

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.
