A nurse is caring for a 45-year-old patient with chronic obstructive pulmonary disease (COPD) who was admitted with acute exacerbation. The patient is receiving oxygen therapy at 2 L/min via nasal cannula and has been started on corticosteroids and bronchodilators. The patient presents with increased dyspnea, productive cough with thick yellow sputum, and reports feeling anxious about breathing difficulties. Vital signs: BP 130/80 mmHg, HR 105 bpm, RR 26/min, O2 sat 84% on room air, temp 101.5°F. Which nursing assessment finding requires the most immediate intervention?

Oxygen saturation below 90% with exertion indicates severe hypoxemia requiring immediate intervention to prevent respiratory failure. Other findings (HR, BP, temp) are less urgent.

Core Nursing Explanation Key Concept Analysis: This question tests the nurse's ability to prioritize assessment findings in a patient with an acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). The core principle is Airway, Breathing, Circulation (ABC) prioritization. In this scenario, the patient's primary problem is respiratory distress, making findings related to Breathing and Oxygenation the highest priority for immediate intervention.

Answer Rationale: An O2 saturation of 88% on room air is the most critical finding. For a patient with COPD in exacerbation, this level of hypoxemia is severe and indicates a failure of the body's compensatory mechanisms. Key Point! While patients with chronic COPD may tolerate lower baseline saturations (e.g., 88-92%), an acute drop or a saturation this low in the context of increased dyspnea and anxiety signals impending Respiratory failure. Immediate intervention (e.g., adjusting oxygen therapy, preparing for non-invasive ventilation) is required to prevent further deterioration.

Distractor Analysis:
Watch out for confusion! Option ② (HR 102 bpm with PVCs) shows Tachycardia and minor arrhythmias, which are common compensatory responses to hypoxemia and anxiety. While it requires monitoring, it is a Circulation issue and is secondary to the primary Breathing problem.
Option ③ (BP 145/90 mmHg with headache) indicates mild hypertension, possibly related to anxiety, corticosteroids, or hypoxia. It is not an immediately life-threatening finding.
Option ④ (Temp 100.8°F) indicates a low-grade fever, consistent with the infective exacerbation suggested by the yellow sputum. This requires intervention (e.g., antibiotics), but does not pose the same immediate threat to life as severe hypoxemia.

Related Concepts: In COPD exacerbation, nursing priorities focus on improving gas exchange, managing anxiety, ensuring effective airway clearance, and monitoring for complications like respiratory failure. Understanding the difference between chronic compensation and acute decompensation is crucial. Concept Summary

Hypoxemia in COPD	An O2 sat 임상 시나리오 Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, a 45-year-old with a 20-pack-year smoking history and known COPD, was admitted yesterday. He is on 2L O2 via nasal cannula but pulled it off because it was irritating his nose. You enter the room and find him leaning forward, using his accessory neck muscles to breathe, and he tells you he "can't catch his breath." Nursing Intervention Strategy: Immediate Assessment & Action (First 2-5 minutes): Apply the ABCs. A: Listen. Is his airway patent? He is speaking, so yes. B: Key Point! Put the oxygen back on! Apply the nasal cannula at 2L/min (or as per order). Check his O2 saturation with a pulse oximeter. Auscultate lung sounds (you'll likely hear wheezes and possibly crackles). C: Check his pulse (rate, rhythm), and capillary refill. Comprehensive Care (Next 10-20 minutes): Administer prescribed PRN bronchodilator via nebulizer. Assist him into a position of comfort, often Tripod position or high-Fowler's. Stay with him, provide calm reassurance to decrease anxiety, which worsens dyspnea. Encourage effective coughing techniques or suction if he cannot clear secretions. Monitoring & Evaluation: Continuously monitor O2 saturation, respiratory rate and effort, and heart rate. Evaluate the effectiveness of bronchodilators. Document your assessments, interventions, and the patient's response. Patient Safety and Precautions: Oxygen Safety: Ensure O2 delivery device is secure and comfortable to prevent removal. No smoking signs must be prominent. Medication Caution: Monitor for side effects of bronchodilators (tachycardia, tremor) and corticosteroids (hyperglycemia, mood changes). Infection Control: The yellow sputum suggests infection. Practice good hand hygiene and ensure sputum specimens are collected if ordered. Nursing Procedure & Medication Flow Administering a Nebulized Bronchodilator (e.g., Albuterol): Perform hand hygiene and check the medication order (Right drug, dose, patient, route, time). Assemble nebulizer cup, connect to air/oxygen source. Pour medication into cup. Place mouthpiece in patient's mouth or apply mask securely. Turn on the compressor. Instruct patient to take slow, deep breaths through the mouth. Treatment lasts 5-15 minutes. Stay with the patient; monitor for relief of symptoms and adverse effects (increased HR, jitteriness). After treatment, assist with oral care (rinse mouth) to prevent oral thrush, especially if on inhaled steroids. A Word from Your Senior Nurse "In the rush of a busy shift, it's easy to get task-focused. But remember, your most powerful tool is your assessment. That pulse ox reading isn't just a number—it's a direct window into whether your patient's brain and heart are getting enough oxygen. When you see a number like 88% in a struggling COPD patient, your internal alarm bells should ring. Don't just chart it and move on. Act, reassess, and advocate. That moment of critical thinking and timely intervention is what defines expert nursing care and truly saves lives. For the NCLEX, breathe, think 'ABCs,' and you'll prioritize like a pro." 핵심 개념 Chronic Obstructive Pulmonary Disease — A progressive lung disease causing chronic airflow limitation, primarily from emphysema and chronic bronchitis. Hypoxemia — Low level of oxygen in the blood (typically SpO2 < 90%), a primary concern in respiratory conditions. ABC Prioritization — A fundamental nursing and emergency care framework: Airway, Breathing, Circulation. Guides immediate action sequencing. Respiratory Failure — Inability of the respiratory system to maintain adequate gas exchange (oxygenation and/or CO2 elimination). Tripod Position — Leaning forward with arms braced on knees or a table; a compensatory posture to improve breathing mechanics in COPD. 마이메르시로 국가고시 완벽 대비 기출문제와 상세 해설을 무료로. 내 약점을 분석하고 진도를 관리하며 더 똑똑하게 공부하세요. 무료로 시작하기 App Store Google Play 학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요.
