A 65-year-old male with a history of recent hip surgery suddenly develops chest pain, shortness of breath, and anxiety. Which assessment finding would be MOST indicative of pulmonary embolism?

Sharp, stabbing chest pain that worsens with inspiration (pleuritic pain) is a classic and specific symptom of pulmonary embolism in postpartum clients. Other findings like leg swelling (Homan's sign is unreliable), crackles (suggests pulmonary edema), or hypotension (nonspecific) are less indicative.

Core Nursing Explanation Key Concept Analysis: This question tests the ability to identify the most specific clinical manifestation of a Pulmonary Embolism (PE). PE occurs when a thrombus (often from a deep vein thrombosis (DVT)) travels to and obstructs a pulmonary artery. The classic symptom triad is dyspnea, pleuritic chest pain, and hemoptysis. The patient's history of recent hip surgery is a major risk factor for DVT/PE due to immobility and potential hypercoagulability.

Answer Rationale: Key Point! The correct answer is Sharp, stabbing chest pain that worsens with inspiration. This is known as pleuritic chest pain. It is caused by inflammation of the parietal pleura lining the chest wall, which is irritated by the infarcted lung tissue distal to the embolism. This symptom is highly characteristic of PE. The sudden onset of dyspnea and anxiety in a post-surgical patient further supports this diagnosis.

Distractor Analysis:
① Watch out for confusion! While unilateral leg swelling suggests DVT (a risk factor for PE), Homan's sign (calf pain on dorsiflexion of the foot) is an unreliable and non-specific sign for DVT and is no longer recommended for assessment. It is not the *most* indicative finding of an *active* PE.
② Bilateral crackles with frothy sputum are classic signs of pulmonary edema (e.g., from left-sided heart failure), not PE. Crackles may occur in PE but are not a defining feature.
④ Tachycardia and hypotension (BP 90/60 mmHg) are signs of hemodynamic instability and can occur in a massive PE. However, these are non-specific and can be seen in many other emergencies (e.g., sepsis, MI, hemorrhage). They indicate severity but not specificity.

Related Concepts: The nursing priority for a suspected PE is to ensure adequate oxygenation (administer O2), notify the provider immediately, and prepare for diagnostic tests (CT pulmonary angiography, V/Q scan) and treatment (anticoagulation like heparin).

Nursing Clinical Practice Guide Clinical Scenario: You are caring for Mr. Johnson, 3 days post-op from a total hip replacement. He calls you to his room stating, "Nurse, I can't catch my breath, and my chest hurts every time I take a deep breath." He appears anxious, tachypneic, and diaphoretic.

Nursing Intervention Strategy: 1. Immediate Assessment (ABCs): Assess airway, breathing (rate, effort, O2 saturation), and circulation (heart rate, blood pressure). Apply supplemental oxygen via nasal cannula or non-rebreather mask to maintain SpO2 > 92%. 2. Focused Assessment: Auscultate lung sounds. In PE, they are often clear initially. Assess for unilateral calf swelling, warmth, or tenderness (signs of DVT). Do NOT perform Homan's sign. 3. Communication & Preparation: Notify the physician/provider STAT. Anticipate orders for stat labs (D-dimer, ABG), imaging (CTPA), and anticoagulant therapy (e.g., IV heparin or subcutaneous enoxaparin). 4. Patient Support: Keep the patient on strict bed rest to prevent further embolization. Stay with the patient, provide calm reassurance to decrease anxiety, which can worsen dyspnea.

Patient Safety and Precautions: Never massage a swollen, painful leg if DVT/PE is suspected, as this could dislodge more clot. For patients on anticoagulants, monitor closely for signs of bleeding (e.g., gums, urine, stool, injection sites).
Nursing Procedure & Medication Flow Anticoagulant Initiation (Harin): - Verify provider order and check baseline labs (PT/INR, aPTT, platelet count). - Administer bolus and start continuous IV heparin infusion per protocol. - Monitor aPTT every 6 hours initially, titrating infusion to therapeutic range (typically 1.5-2.5 times control). - Assess for Heparin-Induced Thrombocytopenia (HIT): Monitor platelet counts.

A Word from Your Senior Nurse "In real clinical practice, trust your assessment. A patient telling you their chest pain is 'sharp and worse when I breathe in' is a huge red flag for PE, especially in a post-op or immobilized patient. Your rapid recognition and action—oxygen, notification, and preparation for diagnostics—directly impact patient survival. On the NCLEX, they love to test the specificity of symptoms. Remember: Pleuritic pain = think lungs (PE, pneumonia, pneumothorax). Crushing pressure = think heart (MI)."
