## 문제

A nurse is assessing a patient with suspected pleurisy. Which assessment finding would be most characteristic of this condition?

## 보기

1. Productive cough with purulent sputum
2. Sharp, stabbing chest pain that worsens with inspiration **✔ 정답**
3. Gradual onset of dyspnea over several days
4. Dull, aching chest pain that improves with movement

**정답: 2**

## 해설

Sharp, stabbing chest pain that worsens with inspiration is the hallmark of pleurisy due to inflamed pleural membranes rubbing during breathing. Other options are more characteristic of conditions like pneumonia or gradual respiratory compromise.

Understanding the Pathophysiology of Pleurisy

Pleurisy, also known as pleuritis, is an inflammation of the pleura—the two thin layers of tissue that separate your lungs from your chest wall. Normally, these layers glide smoothly against each other during breathing. When they become inflamed, the roughened surfaces rub together with every breath, creating a classic friction pattern. The most characteristic symptom stems directly from this mechanical irritation.

Why the Correct Answer is Characteristic

The hallmark of pleurisy is pleuritic chest pain, which is described as a sharp, stabbing chest pain that worsens with inspiration. This occurs because deep breathing, coughing, or sneezing forces the inflamed pleural layers to stretch and grate against one another, directly stimulating the highly sensitive pain fibers in the parietal pleura. The pain is typically localized and unilateral, and patients often instinctively splint their chest or take shallow breaths to minimize the discomfort. This clinical presentation is so distinct that the term "pleuritic pain" is used across various conditions to describe pain of this exact quality. As noted in the provided research, sharp chest pain upon deep breathing is "commonly associated with pleurisy" [1].

Analysis of Incorrect Options

- Option 1: Productive cough with purulent sputum

This finding is more indicative of a lower respiratory tract infection such as pneumonia or acute bronchitis. While pneumonia can certainly cause a secondary pleural inflammation (parapneumonic effusion), the primary and most direct assessment finding for pleurisy itself is the pain, not the presence of infected sputum.

- Option 3: Gradual onset of dyspnea over several days

This pattern is more characteristic of a slowly accumulating pleural effusion, heart failure, or a progressive lung disease. While a patient with pleurisy may develop shallow breathing to avoid pain, the primary symptom is pain, not a gradual, painless shortness of breath. A large pleural effusion, as seen in the case study where a "right pleural effusion" was found on CT, can actually separate the inflamed pleural layers and paradoxically relieve the sharp pleuritic pain, replacing it with a dull ache and dyspnea [1].

- Option 4: Dull, aching chest pain that improves with movement

This description is the opposite of pleuritic pain. Pleuritic pain is sharp and worsens with respiratory movement. Pain that improves with movement is more suggestive of a musculoskeletal origin, such as costochondritis or a muscle strain, where finding a comfortable position can alleviate the discomfort.

Clinical Application and NCLEX-RN Focus

For the NCLEX-RN, recognizing the specific quality of pleuritic pain is a high-yield concept for the Physiological Integrity category. When a patient reports chest pain, your assessment must differentiate its characteristics. A key nursing intervention is to ask the patient to take a deep breath and observe for a sharp increase in pain, which strongly points to a pleural origin. The case study reinforces this by highlighting that even when an atypical underlying cause like pyogenic spondylitis is present, the initial presentation can still manifest with the classic symptom of "right-sided pleuritic chest pain" [1]. This underscores that the pain quality itself is a reliable clinical cue, even if the root cause is unexpected. Your priority is to identify the symptom pattern, manage pain, and monitor for complications like the development of a significant pleural effusion that could alter the clinical picture.References (research sources)

## 임상 시나리오

Pleuritic Pain AssessmentRecognizing the Hallmark Sign
The defining symptom of pleurisy is pleuritic chest pain, described as a sharp, stabbing sensation that worsens with inspiration. This occurs because inflamed pleural layers grate against each other during breathing.

Patients often present with splinting of the affected side and rapid, shallow breaths to minimize pain. The pain is typically unilateral and localized. Auscultation may reveal a pleural friction rub, a leathery, grating sound heard during both inspiration and expiration.

CautionDifferentiate pleuritic pain from cardiac ischemic pain, which is often described as pressure or squeezing and is not typically worsened by inspiration. Always rule out life-threatening causes like pulmonary embolism or pneumothorax in patients with acute onset pleuritic pain.

## 핵심 개념

- **Pleurisy** — Inflammation of the pleura, the double-layered membrane surrounding the lungs and chest wall, causing pain during respiration.
- **Pleuritic Pain** — Sharp, stabbing chest pain that intensifies with deep breathing, coughing, or sneezing due to inflamed pleural surfaces rubbing together.
- **Parietal Pleura** — The outer layer of the pleura lining the chest wall, which is highly sensitive to pain; its irritation causes localized pain.
