해설
For a patient with a confirmed PE, the highest priority according to the ABCs (Airway, Breathing, Circulation) framework is optimizing respiratory function. Positioning the patient in high Fowler's position and encouraging deep breathing immediately maximizes lung expansion, decreases the work of breathing, and improves oxygenation. While monitoring for bleeding risks associated with anticoagulant therapy is essential, it is secondary to addressing the acute and life-threatening respiratory compromise..
Core Nursing ExplanationKey Concept Analysis: This question tests the application of priority-setting frameworks in a patient with a life-threatening condition. The patient has a confirmed Pulmonary Embolism (PE), which is a blockage of one or more pulmonary arteries by a thrombus (usually from the deep veins). This obstruction increases pulmonary vascular resistance, impairs gas exchange, and can lead to hypoxemia and right ventricular strain. The immediate threat is to Breathing. While anticoagulation is the definitive treatment to prevent clot extension, managing the acute respiratory compromise takes precedence.
Answer Rationale: Key Point! The correct answer is ③ Position the patient in high Fowler's position and encourage deep breathing exercises. This intervention directly addresses the primary problem—impaired gas exchange and respiratory distress. High Fowler's position (sitting upright) maximizes chest expansion and lung volume, decreasing the work of breathing and improving oxygenation. Deep breathing exercises help prevent atelectasis and promote ventilation in unaffected lung areas. This is the most immediate, independent nursing action to support the patient's airway, breathing, and circulation (ABCs).
Distractor Analysis:
Watch out for confusion!① Monitor oxygen saturation continuously and administer supplemental oxygen as needed: This is a very close second in priority and is critically important. However, the question asks for the nursing intervention that is the highest priority. Positioning and deep breathing are active, immediate interventions to improve the physiological status, while monitoring and administering oxygen are assessments and supportive treatments that follow. In many NCLEX scenarios, the active, independent nursing action to alleviate the primary symptom is prioritized over monitoring.
Watch out for confusion!② Assess for signs of bleeding and monitor coagulation studies regularly: This is a crucial safety intervention related to the anticoagulant therapy. However, it addresses a potential complication of the treatment, not the immediate, life-threatening problem (the PE itself). According to Maslow's Hierarchy of Needs and the ABCs, physiological needs (breathing) come before safety needs (preventing bleeding).
Watch out for confusion!④ Educate the patient about activity restrictions and fall prevention measures: Patient education is essential for long-term management and safety, especially for a patient on anticoagulants who is at risk for bleeding from falls. However, education is never the highest priority in an acute, unstable situation. It is part of the planning and implementation phases for discharge and ongoing care.
Related Concepts: The NCLEX frequently tests the ability to distinguish between treating the disease (anticoagulation) and managing the symptoms (respiratory support). Always apply the ABCs framework first. For a PE, remember the triad of symptoms: dyspnea, pleuritic chest pain, and hemoptysis. Nursing priorities are oxygen, positioning, and monitoring for deterioration (e.g., signs of right-sided heart failure or hemodynamic instability).
Concept Summary
Concept
Description
Application in PE
Pulmonary Embolism (PE)
Obstruction of pulmonary artery by a thrombus, causing V/Q mismatch and hypoxemia.
Primary problem: Impaired gas exchange and respiratory distress.
ABCs Priority Framework
Airway, Breathing, Circulation. Establishes the order of nursing actions.
Breathing is the immediate priority. Interventions must support oxygenation.
Anticoagulant Therapy
Treatment to prevent clot extension and new clot formation (e.g., heparin, warfarin, DOACs).
Definitive treatment but introduces risk (bleeding). Monitoring is a secondary priority.
High Fowler's Position
Positioning patient sitting upright at 80-90 degrees.
Maximizes lung expansion, decreases work of breathing, improves oxygenation.
Side-by-Side Comparison!
Priority for a Patient with PE
Priority for a Patient on Anticoagulants (Stable)
1. Optimize Breathing (O2, positioning) 2. Monitor for Complications of PE (e.g., hemodynamic instability) 3. Manage Anticoagulation & Monitor for Bleeding
1. Prevent Injury & Monitor for Bleeding 2. Ensure Therapeutic Anticoagulation (monitor labs) 3. Patient Education on safety and medication adherence
Anatomy, Physiology & Pharmacology Points
Pathophysiology: A clot travels to the lungs → obstructs pulmonary blood flow → increased pulmonary artery pressure → increased right ventricular afterload → right ventricular strain/failure. The obstructed area results in ventilation-perfusion (V/Q) mismatch (ventilation without perfusion), causing hypoxemia.
Positioning Rationale: High Fowler's position uses gravity to lower the diaphragm, increasing thoracic cavity volume and allowing for greater lung expansion, which improves ventilation.
Anticoagulant Caution: Drugs like heparin or enoxaparin do not dissolve existing clots; they prevent new ones. Major side effect is bleeding (monitor aPTT, anti-Xa levels, PT/INR).
Memory Tips
PE Priority Mnemonic: "O2 Before Bleeding" – Address Oxygenation (Airway/Breathing) before worrying about bleeding risks from treatment.
Think ABCs: Always ask yourself: "What is threatening the patient's Airway, Breathing, or Circulation RIGHT NOW?" For PE, it's always Breathing.
High-Frequency NCLEX Topics
PE is a classic NCLEX topic for testing priority-setting and clinical judgment. You will see questions on:
Watch Out for Question Variations!
The same concept can be tested differently:
Variation 1 (Assessment Focus): "A patient with suspected PE reports sudden shortness of breath. Which assessment finding should the nurse report immediately?" (Answer: Oxygen saturation < 90% or signs of hemodynamic instability).
Variation 2 (Intervention Focus): "The nurse is preparing to administer enoxaparin to a patient with a PE. Which patient finding would require the nurse to hold the medication and notify the provider?" (Answer: Active bleeding, platelet count < 50,000/mm3, or allergic reaction).
Variation 3 (Evaluation Focus): "Which statement by a patient receiving warfarin for PE indicates effective teaching?" (Answer: "I will avoid activities that could cause me to fall and bruise.").
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 68, was admitted 6 hours ago with a confirmed PE. He is receiving a heparin infusion and reports a 7/10 sharp chest pain that worsens with deep inspiration. His SpO2 is 92% on 2L nasal cannula, respiratory rate is 24, and he appears anxious.
Nursing Intervention Strategy:
Immediate Action (Priority): Assist Mr. Johnson to High Fowler's position. Coach him in slow, deep breathing exercises to manage pain and anxiety while improving ventilation. Reassess his SpO2 and respiratory effort after positioning.
Assessment: Perform a focused respiratory assessment (lung sounds, work of breathing). Monitor vital signs frequently, especially heart rate, blood pressure, and oxygen saturation. Assess pain level and characteristics.
Collaborative Care: Administer supplemental oxygen as ordered to maintain SpO2 > 92%. Administer analgesics (e.g., acetaminophen or opioids cautiously) for pleuritic pain as ordered. Ensure the heparin infusion is running at the correct rate via an IV pump.
Safety & Monitoring: Once the acute respiratory status is addressed, implement bleeding precautions. Monitor coagulation labs (aPTT for heparin). Assess for signs of bleeding (gums, urine, stool, injection sites). Use a soft-bristle toothbrush and electric razor.
Education & Evaluation: When stable, educate on the importance of anticoagulants, fall prevention, and recognizing signs of bleeding or recurrent PE (increased shortness of breath). Evaluate understanding.
Patient Safety and Precautions:
Contraindications: Do not massage the legs (could dislodge a DVT). Avoid IM injections due to bleeding risk.
Medication Cautions: Heparin has a narrow therapeutic range. Always use an IV pump. Protamine sulfate is the antidote for heparin overdose.
Key Monitoring: Watch for signs of worsening PE or right heart failure (e.g., jugular venous distension (JVD), hypotension, increased edema).
Verify the order and calculate the correct infusion rate (units/hr).
Use a dedicated IV line or port. Label the line clearly "HEPARIN INFUSION".
Program the IV pump with the correct rate. Use guardrails if available.
Draw aPTT levels per protocol (usually 6 hours after initiation or rate change).
Adjust the infusion rate based on the aPTT result and hospital protocol (therapeutic range is typically 1.5-2.5 times the control).
A Word from Your Senior Nurse
"In the rush of managing drips and labs for a PE patient, never forget the power of simple, hands-on nursing care. Helping a struggling patient sit up and coaching their breathing can be more immediately effective and comforting than any monitor. Your assessment doesn't stop at the numbers; it's in watching their chest rise, seeing the fear in their eyes lessen, and hearing their breath ease. On the NCLEX and at the bedside, remember: fix the problem in front of you first. For a patient who can't breathe, your first move is always to help them get air."
