NP125 Med Surg Exam | Nurselytic

Correct Answer: A

Rationale: X-rays are commonly used to diagnose osteoarthritis as they effectively visualize joint space narrowing, osteophyte formation, and subchondral sclerosis, which are characteristic of OA. These imaging findings assist in confirming the diagnosis and assessing disease progression. Lithography is not a diagnostic tool used for OA. It primarily refers to a printing method and has no relevance to imaging joints affected by osteoarthritis or diagnosing the condition scientifically. Ultrasound can visualize soft tissues but is not routinely used for OA diagnosis. It does not provide the detailed assessment of joint degeneration seen in X-rays, making it less appropriate for identifying OA-related changes. Echocardiograms are used to assess heart function and have no application in diagnosing osteoarthritis. They are irrelevant in imaging joint structures or evaluating degenerative joint diseases scientifically.
