A postpartum client on her third day after vaginal delivery reports sudden onset of sharp chest pain and shortness of breath. Which assessment finding would be most indicative of pulmonary embolism?

A 28-year-old woman delivered her first baby vaginally 3 days ago. She has been ambulating minimally due to perineal discomfort and has been primarily bed-bound. She suddenly develops sharp, stabbing chest pain and reports feeling short of breath.

## 보기

1. Bilateral lower extremity edema with pitting
2. Gradual onset of dyspnea over several hours
3. Chest pain that worsens with deep inspiration
4. Sudden onset of severe dyspnea with chest pain **✔ 정답**

**정답: 4**

## 해설

Pulmonary embolism presents with sudden onset of severe dyspnea and chest pain. Bilateral edema suggests other issues, gradual dyspnea is less typical, and chest pain worsening with inspiration can occur in pleuritis but is not the most indicative.

Understanding the Clinical Scenario

This question presents a classic high-risk postpartum situation. The client is on her third day after a vaginal delivery, has been relatively immobile due to perineal pain, and now reports a sudden onset of sharp, stabbing chest pain and shortness of breath. The physiological context of the puerperium, combined with the clinical presentation, should immediately raise suspicion for a thromboembolic event. Pregnancy and the postpartum period are hypercoagulable states, a fact that significantly increases the risk of venous thromboembolism (VTE), including pulmonary embolism (PE) . The description of the client being "primarily bed-bound" further compounds this risk through venous stasis, completing two-thirds of Virchow's triad (hypercoagulability and stasis).

Analyzing the Answer Choices

Let's break down why each option is or is not the most indicative finding for a pulmonary embolism in this specific context.

Option 1: Bilateral lower extremity edema with pitting

While a deep vein thrombosis (DVT) is a common precursor to PE, its classic sign is a unilateral swollen, painful extremity. Bilateral, pitting edema is a much more common finding in postpartum patients due to the mobilization of extracellular fluid that accumulated during pregnancy and is not a specific indicator of an acute PE. This finding would be more concerning for a fluid volume excess related to preeclampsia or cardiac dysfunction, but it is not the most indicative sign of a PE.

Option 2: Gradual onset of dyspnea over several hours

The stem of the question emphasizes a "sudden onset" of symptoms. While dyspnea is a hallmark symptom of PE, its presentation is classically abrupt, not gradual. A gradual onset of dyspnea could point to other postpartum complications like peripartum cardiomyopathy, pulmonary edema, or even anxiety. The key differentiator for an acute PE is the suddenness of the event, making this option inconsistent with the classic presentation.

Option 3: Chest pain that worsens with deep inspiration

This describes pleuritic chest pain, which is a very common and important symptom of a PE. When a pulmonary embolus lodges in a pulmonary artery, it can cause infarction and inflammation of the adjacent lung tissue and pleura, leading to pain that intensifies with breathing or coughing. This is a strong finding. However, we must consider if it is the most indicative finding when compared to the correct answer.

Option 4: Sudden onset of severe dyspnea with chest pain

This is the most indicative finding. The combination of sudden onset and the pairing of severe dyspnea with chest pain captures the classic, dramatic clinical presentation of an acute pulmonary embolism. The suddenness points directly to an acute vascular occlusion, where a clot abruptly obstructs pulmonary blood flow, instantly causing a ventilation-perfusion (V/Q) mismatch and triggering severe dyspnea. The simultaneous chest pain, often pleuritic, completes the picture. While Option 3 describes the nature of the pain, Option 4 more accurately describes the overall clinical syndrome—a sudden, catastrophic event—which is the hallmark of a PE diagnosis in the emergency setting . The challenge in diagnosis, as noted in the literature, is that symptoms can mimic normal pregnancy or other conditions, but a sudden, combined presentation of these cardinal symptoms in a high-risk patient is the most powerful clinical indicator .

Key Takeaway for NCLEX-RN

The critical clinical reasoning step here is recognizing the pattern of symptom onset. A PE is an acute vascular emergency. The word "sudden" in the client's history is not just a descriptor; it is the most significant diagnostic clue. When you see a postpartum patient with risk factors for VTE (immobility, hypercoagulable state) who develops an abrupt onset of respiratory distress and chest pain, your nursing assessment must prioritize the immediate suspicion of a pulmonary embolism. This recognition is the first step in initiating the rapid response and diagnostic workup (such as a CT pulmonary angiogram) that can be life-saving, as cardiovascular emergencies in the puerperium require prompt, high-quality management to prevent adverse outcomes .

Clinical Practice Guide: Postpartum Pulmonary Embolism Assessment

A postpartum client presenting with sudden-onset dyspnea and chest pain requires immediate evaluation for pulmonary embolism (PE). The classic triad of symptoms includes sudden severe dyspnea, pleuritic chest pain, and hemoptysis, though the full triad is not always present. The most critical diagnostic indicator is the abrupt nature of the respiratory distress, which distinguishes PE from other postpartum complications like fluid overload or infection.

Nursing assessment must prioritize airway, breathing, and circulation (ABCs). Apply oxygen to maintain SpO2 above 94%, establish IV access, and prepare for continuous monitoring of vital signs and cardiac rhythm. Notify the provider immediately and anticipate orders for a STAT CT pulmonary angiography (CTPA), which is the gold standard diagnostic test. While preparing for transfer, assess for signs of deep vein thrombosis (DVT) in the lower extremities, noting that a unilateral swollen, red, or painful calf is more specific than bilateral edema.

Key differentials to rule out include amniotic fluid embolism (which presents more acutely during or immediately after delivery with cardiovascular collapse), postpartum cardiomyopathy (gradual onset of dyspnea, orthopnea), and anxiety or panic attack. Given the hypercoagulable state of the puerperium and the risk factor of immobility, a high index of suspicion must be maintained. Once PE is confirmed, treatment typically involves therapeutic anticoagulation, initially with unfractionated heparin or low-molecular-weight heparin, which is safe for breastfeeding mothers.

## 핵심 개념

- **Virchow's Triad** — The three factors contributing to thrombosis: hypercoagulability, venous stasis, and endothelial injury.
- **Puerperium** — The period following childbirth during which the mother's reproductive organs return to their nonpregnant state, typically 6 weeks.
- **Pulmonary Embolism (PE)** — A blockage in one of the pulmonary arteries in the lungs, most often caused by blood clots that travel from the legs (DVT).
- **Deep Vein Thrombosis (DVT)** — A blood clot that forms in a deep vein, usually in the legs, which can dislodge and travel to the lungs causing a PE.
- **Pleuritic Chest Pain** — Sharp chest pain that worsens during breathing, coughing, or sneezing, caused by inflammation of the pleura.
