What is most likely to cause the pain experienced in the later stages of OA?

Correct Answer: D

Rationale: In osteoarthritis (OA), the pain experienced in later stages is mainly due to bone surfaces rubbing together (Option D). As OA progresses, the protective cartilage between bones wears down, leading to direct contact between bones during movement, causing pain. Option A, crepitation, refers to the grating, crackling, or popping sounds heard with joint movement in OA but is not the primary cause of pain. Options B and C, Bouchard's and Heberden's nodes respectively, are bony enlargements seen in OA but are not directly responsible for the pain. These nodes are a result of osteophyte formation at the joint margins, which can limit movement but do not directly cause the pain associated with bone-on-bone contact. Understanding the pathophysiology of OA is crucial for healthcare professionals, especially nurses, as they play a vital role in assessing and managing patients with this condition. Recognizing the primary source of pain in OA helps in providing appropriate interventions and education to improve patient outcomes and quality of life.

Correct Answer: B

Rationale: In dermatomyositis, a systemic autoimmune disease affecting the skin and muscles, the correct outcome during the acute phase is for the patient not to experience aspiration (Option B). This is because dermatomyositis can involve weakness of the muscles involved in swallowing, leading to a risk of aspiration pneumonia. Option A, relating improvement in pain, is not the most appropriate outcome for dermatomyositis as pain management is important but not the primary concern during the acute phase. Option C, performing active range of motion four times daily, may exacerbate muscle weakness and should be carefully monitored based on individual patient needs. Option D, maintaining absolute rest of affected joints, is not ideal as it can lead to joint stiffness and contractures. In an educational context, it is crucial for nursing students preparing for the NCLEX to understand the specific manifestations and management of dermatomyositis, including the appropriate outcomes to prioritize during the acute phase to ensure patient safety and optimal recovery. Nurses must be able to prioritize care based on the patient's condition and the pathophysiology of the disease to provide effective and safe care.
