Which diagnostic assessment method is commonly used for osteoarthritis (O
X-ray.
Lithography.
Ultrasound.
Echocardiogram.
The Correct Answer is A
Choice 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.
Choice B rationale
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.
Choice C rationale
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.
Choice D rationale
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. .

Correct Answer is ["C","D","E","F"]
Explanation
Choice A rationale
Assessing the range of motion of a severely injured leg is not appropriate during initial evaluation. Movement can worsen the injury or disrupt stabilizing measures such as splints or dressings.
Choice B rationale
Asking the patient to stand or bear weight risks further injury and is contraindicated in cases of visible deformity or massive bleeding.
Choice C rationale
Evaluating skin color helps identify potential ischemia, vascular compromise, or inadequate perfusion. Pallor or cyanosis can indicate significant circulation issues needing urgent care.
Choice D rationale
Paresthesia (tingling or numbness) reflects nerve function and can reveal nerve damage or compromised blood flow, necessitating thorough evaluation.
Choice E rationale
Pain assessment is crucial for identifying the severity of injury and potential complications such as compartment syndrome. Pain disproportionate to the injury suggests complications.
Choice F rationale
Palpating pulses assesses blood flow, ensuring the presence of distal perfusion. Absent or weak pulses require urgent vascular intervention to prevent tissue necrosis.
Correct Answer is C
Explanation
Choice A rationale
Checking blood pressure does not directly address the faint pulses and cool foot. While hypotension could contribute to peripheral perfusion issues, the signs described more likely indicate compartment syndrome, which requires urgent action.
Choice B rationale
Repositioning the leg might provide some comfort but does not alleviate the potential compartment syndrome. Elevation could worsen ischemia by reducing arterial blood flow.
Choice C rationale
Compartment syndrome is a medical emergency caused by increased pressure within a muscle compartment. This pressure compromises circulation and tissue viability. The nurse must notify the health care provider immediately to prevent permanent damage.
Choice D rationale
Assessing the incision for redness delays addressing the critical signs of potential compartment syndrome. Redness indicates infection, but faint pulses and a cool extremity necessitate more urgent evaluation.
