## 문제

A nurse is caring for a client with osteoarthritis who is experiencing increased joint pain and stiffness. The client reports difficulty with mobility and weight-bearing activities. Which nursing intervention should be the priority?

## 보기

1. Encourage vigorous range-of-motion exercises to prevent joint contractures
2. Apply heat therapy to affected joints during periods of acute inflammation
3. Administer prescribed anti-inflammatory medications as ordered **✔ 정답**
4. Recommend complete bed rest until inflammation subsides

**정답: 3**

## 해설

During acute osteoarthritis flare-ups, rest and joint protection are prioritized to reduce inflammation and prevent damage. Heat therapy can worsen inflammation and is contraindicated in acute phases.

Understanding the Priority in Osteoarthritis Pain Management

When a client with osteoarthritis (OA) presents with increased joint pain and stiffness that limits mobility, the immediate nursing priority is to interrupt the acute pain cycle. The rationale is grounded in the fundamental principle that unrelieved pain is not merely a symptom but a barrier to all other therapeutic interventions. According to the systematic review and meta-analysis by Liu et al., non-pharmacological treatments are recommended as first-line management for knee OA [1]; however, during an acute exacerbation where pain is the primary reason for immobility, pharmacological management often becomes the necessary bridge to enable participation in those very treatments. The prescribed anti-inflammatory medication directly targets the pathophysiological drivers of pain—prostaglandin synthesis and the inflammatory cascade within the joint—thereby reducing nociceptive input. Once the severe pain is blunted, the client can tolerate and benefit from the essential non-pharmacological, conservative interventions that form the cornerstone of long-term OA management [1,2].

Analysis of Incorrect Options

**Option 1: Encourage vigorous range-of-motion exercises to prevent joint contractures.**

This intervention is contraindicated during an acute pain flare. The evidence-based approach to exercise in OA is conservative and targeted, not vigorous. Saki et al. describe a neuromuscular exercise program that combines core stability, balance, and lower-limb strength, emphasizing controlled, quality movement rather than aggressive range-of-motion [2]. Similarly, Patel and Muley specifically studied isometric exercise, a static form of muscle contraction that minimizes joint movement, and found it effective for reducing pain perception in elderly patients with knee OA [3]. Forcing a painful, inflamed joint through a vigorous range of motion would exacerbate tissue stress, increase pain, and potentially cause protective muscle spasm, directly contradicting the principles of pain neuroscience education and conservative management [2,3].

**Option 2: Apply heat therapy to affected joints during periods of acute inflammation.**

This option presents a critical clinical contradiction. While thermotherapy is a recognized non-pharmacological intervention for OA, its application is phase-dependent. Heat therapy promotes vasodilation, which increases blood flow and can worsen edema and the inflammatory process in an acutely inflamed joint. During an acute flare, cold therapy (cryotherapy) is indicated to cause vasoconstriction, reduce metabolic demand, and slow nerve conduction velocity, thereby providing analgesia and limiting inflammation. The systematic review by Liu et al. supports the use of non-pharmacological interventions but implies the need for appropriate clinical reasoning in their application [1]. Applying heat to an acutely inflamed joint is physiologically counterproductive and would likely intensify the client's pain and swelling.

**Option 4: Recommend complete bed rest until inflammation subsides.**

Complete bed rest is a harmful and outdated recommendation for OA management. The sequelae of immobility—including muscle atrophy, joint contracture, and cardiovascular deconditioning—rapidly compound the client's existing mobility difficulties. The entire body of current evidence strongly advocates for activity modification, not cessation. The feasibility study by Oliveira et al. on an increased hip flexion gait exercise program demonstrates that even in individuals with obesity and symptomatic knee OA, structured exercise is both safe and potentially beneficial . The goal is to find a therapeutic window of movement that does not exacerbate pain, replacing injurious rest with protective, pain-free activities such as the isometric exercises shown to reduce pain perception [3] or the targeted neuromuscular training protocols that address strength, balance, and core stability [2].References (research sources)

## 임상 시나리오

Managing Acute OA Pain FlarePrioritizing Pharmacological Intervention to Restore Function
The priority during an acute osteoarthritis exacerbation with severe pain limiting mobility is to administer prescribed anti-inflammatory medications. This directly interrupts the pain cycle by inhibiting prostaglandin synthesis, reducing nociceptive input.

Pain relief is a bridge to function. Once severe pain is blunted, the client can tolerate and benefit from essential non-pharmacological interventions like conservative exercise, which are the cornerstone of long-term OA management.

CautionAvoid vigorous exercise or complete bed rest during a flare. Heat application can worsen acute inflammation; cold therapy may be a more appropriate comfort measure initially.

## 핵심 개념

- **Osteoarthritis (OA)** — A degenerative joint disease characterized by cartilage breakdown, leading to pain, stiffness, and reduced mobility.
- **Nociceptive Pain** — Pain arising from actual or threatened damage to non-neural tissue, due to the activation of nociceptors, as seen in joint inflammation.
- **Prostaglandin Synthesis** — The biological process of creating prostaglandins, lipid compounds that mediate inflammation and pain signaling, which is inhibited by NSAIDs.
- **Acute Exacerbation** — A sudden worsening of disease symptoms, such as a flare-up of joint pain and inflammation in osteoarthritis.
- **First-line Management** — The initial recommended treatment for a condition, which for chronic OA includes non-pharmacological interventions like exercise and weight management.
