## 문제

A nurse is assessing a 60-year-old client with a 10-year history of rheumatoid arthritis. Which assessment finding would be most indicative of disease progression and require immediate attention?

## 보기

1. Morning stiffness lasting 2 hours that improves with activity
2. Symmetrical joint swelling in the hands and wrists with mild tenderness
3. Fatigue and low-grade fever of 100.2°F (37.9°C) for the past week
4. New onset of numbness and tingling in the fingers with decreased grip strength **✔ 정답**

**정답: 4**

## 해설

New onset numbness and tingling in fingers with decreased grip strength indicates potential neurological complications like carpal tunnel syndrome or cervical spine involvement, requiring immediate attention. Other options are common RA symptoms but less urgent.

Understanding the Priority: Recognizing Cervical Myelopathy in RA

When a client with a long-standing history of rheumatoid arthritis (RA) presents with new neurological complaints, the clinical priority shifts from managing chronic joint inflammation to ruling out a potentially devastating complication: rheumatoid cervical spondylitis (RCS), or RA involvement of the cervical spine. The correct answer is the new onset of numbness and tingling in the fingers with decreased grip strength, as this is the most indicative finding of disease progression requiring immediate attention.

Pathophysiology of the Finding

RA is a chronic systemic inflammatory disorder, not just a disease of the joints. The inflammatory process, known as chronic synovitis, can affect the cervical spine, leading to erosion of bone and laxity of crucial ligaments. This structural damage results in instability and subluxation, most commonly anterior atlantoaxial subluxation (AAS) [1]. The danger lies in the potential for the unstable vertebrae to compress the spinal cord or brainstem. The new onset of numbness and tingling (paresthesia) in the fingers, coupled with decreased grip strength (motor weakness), are classic signs of an evolving cervical myelopathy [3,4]. These symptoms indicate that the spinal cord is being compromised, a condition that can progress to irreversible neurological damage, paralysis, or even sudden death from brainstem compression if not identified and managed urgently [3].

Analysis of Incorrect Options

- Option 1: Morning stiffness lasting 2 hours that improves with activity is a hallmark clinical feature of active RA. While it signals active inflammatory disease, it is a manifestation of the peripheral joint pathology and does not, by itself, indicate a dangerous progression like cord compression.

- Option 2: Symmetrical joint swelling in the hands and wrists with mild tenderness is the classic presentation of RA in the peripheral joints. This is an expected finding in a client with a 10-year history of the disease and represents the chronic, ongoing inflammatory process, not a new, emergent complication.

- Option 3: Fatigue and a low-grade fever of 100.2°F (37.9°C) are systemic manifestations of the inflammatory process inherent to RA. While these symptoms warrant monitoring, they are constitutional and do not carry the same immediate threat of permanent neurological injury as a new focal neurological deficit.

Clinical Reasoning and Urgency

The critical insight from the provided evidence is that patients with RCS "may remain minimally symptomatic until late," underscoring the need for structured surveillance [3]. Therefore, the first appearance of any neurological sign, such as paresthesia or weakness, must be treated as a sentinel event. A study using MRI to evaluate RA patients with subluxations found that neurological signs were used to classify the severity of spinal cord compression, directly linking clinical findings like those in Option 4 to the pathology . The nurse's immediate responsibility is to recognize these signs as potential indicators of atlantoaxial instability or subaxial subluxation, promptly notify the provider, and protect the patient from further spinal cord injury, such as by immobilizing the cervical spine and avoiding movements that could worsen the compression [1,2].References (research sources)

## 임상 시나리오

RA with New Neurologic Deficits: Rule Out Cervical MyelopathyA neurosurgical emergency requiring immediate immobilization and imaging
In a patient with long-standing rheumatoid arthritis, any new onset of paresthesia or motor weakness in the extremities must be treated as a cervical myelopathy until proven otherwise. The most common cause is atlantoaxial subluxation from ligamentous erosion.

Immediately place the patient in a rigid cervical collar and maintain strict spinal precautions. Notify the provider urgently and prepare for emergent MRI of the cervical spine. Do not perform a range of motion assessment, as manipulation can worsen cord compression.

CautionDo not mistake these findings for a peripheral neuropathy or carpal tunnel syndrome. The presence of decreased grip strength alongside sensory changes points to an upper motor neuron lesion from cord compression, which can rapidly progress to irreversible paralysis or respiratory failure.

## 핵심 개념

- **Cervical Myelopathy** — Spinal cord compression in the neck, often due to RA-related atlantoaxial subluxation, causing neurological deficits like numbness and weakness.
- **Atlantoaxial Subluxation** — Instability or partial dislocation of the first and second cervical vertebrae, a serious complication of RA that can compress the spinal cord.
- **Synovitis** — Inflammation of the synovial membrane lining a joint, the primary pathological process in RA causing pain, swelling, and stiffness.
- **Extra-articular Manifestations** — Systemic effects of RA occurring outside the joints, such as fatigue, fever, rheumatoid nodules, or cervical spine involvement.
- **Morning Stiffness** — Prolonged joint stiffness upon waking, a hallmark symptom of active RA reflecting synovial inflammation, typically lasting over one hour.
