A nurse is caring for multiple patients on a medical-surgical unit. Which patient should the nurse assess first?

The COPD patient with increased shortness of breath and SpO2 88% requires immediate assessment due to potential respiratory compromise, which is highest priority per ABC principles. Other patients have stable or less urgent issues.

Core Nursing Explanation Key Concept Analysis: This question tests the core nursing skill of prioritization using the ABC (Airway, Breathing, Circulation) framework. When multiple patients require attention, the nurse must first assess the patient with a threat to a Key Point! life-sustaining physiological function. The ABCs are the foundation of this decision-making process.

Answer Rationale: The correct answer is the patient with Chronic Obstructive Pulmonary Disease (COPD) experiencing increased shortness of breath and an SpO2 of 88%. Key Point! A pulse oximetry reading below 90% generally indicates hypoxemia. In a patient with known COPD, a sudden worsening of breathing status is a red flag for acute exacerbation, respiratory failure, or other complications like pneumonia. This represents an immediate threat to the patient's Breathing, which is the "B" in ABCs and takes the highest priority.

Distractor Analysis:
• Patient 1 (Diabetes, Blood Glucose 180 mg/dL): A blood glucose of 180 mg/dL is elevated (hyperglycemia) but not an immediate life-threatening emergency. It requires monitoring and intervention, but it does not trump an acute breathing problem. Watch out for confusion! A blood glucose level below 70 mg/dL (hypoglycemia) would be a high-priority, ABC-relevant issue due to the risk of altered mental status and seizures.
• Patient 3 (Post-op, Pain 6/10): While pain management is an important part of nursing care and patient comfort, unrelieved postoperative pain is not typically an immediate threat to life. The patient is stable, and the pain medication is "due," not overdue for an extended period. Pain, while significant, is prioritized after ABC issues.
• Patient 4 (Hypertension, BP 160/95 mmHg): This blood pressure is elevated but likely chronic for this patient. It requires monitoring and medication adjustment but is not an acute hypertensive crisis (which would involve signs of end-organ damage like severe headache, vision changes, or chest pain). Patient education, while crucial, is a lower-priority activity when another patient has a potential physiological crisis.

Related Concepts: This scenario integrates Maslow's Hierarchy of Needs (physiological needs like breathing come first) and the nursing process (assessment is the first step, and the urgency of that assessment is determined by patient stability). It also touches on disease-specific knowledge, recognizing that a change in baseline status for a COPD patient is a critical finding.

Concept Summary • Prioritization Principle: ABCs (Airway, Breathing, Circulation) > Life-threatening changes > Acute over chronic > Actual over potential problems. • Critical Values: SpO2 < 90% is a sign of hypoxemia requiring intervention. • COPE with COPD: Any acute increase in dyspnea, sputum production, or decrease in oxygenation in a COPD patient signals a possible exacerbation.

Side-by-Side Comparison!

Priority Level	Clinical Example	Rationale (ABC Framework)
High (Immediate)	SOB, SpO2 88%, Chest pain, Active bleeding	Direct threat to Airway, Breathing, or Circulation.
Intermediate (Urgent)	Acute pain (7/10), Hyperglycemia (300 mg/dL), Fever 102°F	Requires prompt intervention to prevent deterioration, but not immediately life-threatening.
Low (Routine)	Discharge teaching, Stable vital signs, Routine medication administration	Important for care continuity but can be safely delayed for higher-priority issues.

Anatomy, Physiology & Pharmacology Points • Physiology of Hypoxemia: Low SpO2 indicates inadequate oxygen saturation of hemoglobin. The body compensates initially with tachypnea (increased respiratory rate) and tachycardia. Prolonged hypoxemia leads to tissue damage, confusion, and eventual organ failure. • COPD Pathophysiology: Characterized by airflow limitation (from emphysema and/or chronic bronchitis), making it difficult to exhale fully. During an exacerbation, this limitation worsens dramatically, trapping more air and impairing gas exchange.

Memory Tips • ABCs are as easy as 1-2-3: Always assess Airway, Breathing, Circulation FIRST. No air = no life. No breath = no life. No circulation = no life. • COPD "RED FLAG" Mnemonic: Respiratory rate increased, Exacerbation of SOB, Decreased O2 saturation (

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a 30-bed medical-surgical unit. During morning med pass, the nursing assistant informs you that Mr. Johnson, a 62-year-old with severe COPD admitted for pneumonia, is "breathing really hard" and says he "can't catch his breath." You immediately go to his room.

Nursing Intervention Strategy: 1. Immediate Assessment (ABCs): Upon entering, visually assess work of breathing (use of accessory muscles, nasal flaring, tripod positioning), listen for breath sounds (wheezes, crackles, diminished sounds), and check the monitor for SpO2 (88%), heart rate (120 bpm), and respiratory rate (32/min). 2. Intervention & Monitoring: Apply supplemental oxygen via nasal cannula as per the physician's order or protocol (e.g., start at 2 L/min in a COPD patient to avoid suppressing the hypoxic drive, then titrate to achieve SpO2 88-92%). Stay with the patient. Assist him into a position of comfort, often leaning forward on the bedside table (tripod position). 3. Communication & Collaboration: Call for help (another nurse or rapid response if needed). Notify the physician/provider immediately, reporting your assessment using SBAR (Situation, Background, Assessment, Recommendation). Prepare for additional orders: stat arterial blood gas (ABG), chest X-ray, nebulizer treatments (e.g., albuterol), or possibly transfer to a higher level of care. 4. Ongoing Care & Reassessment: After initial stabilization, frequently reassess vital signs, breath sounds, and patient comfort. Administer prescribed medications. Provide calm, clear explanations to reduce anxiety, which can worsen dyspnea.

Patient Safety and Precautions: • Key Point! In patients with chronic CO2 retention (common in severe COPD), high-flow oxygen can depress the respiratory drive. Titrate oxygen carefully to target SpO2 of 88-92%. • Monitor closely for signs of respiratory fatigue, which may precede respiratory arrest (e.g., slowing respiratory rate after a period of tachypnea, decreased level of consciousness).

Nursing Procedure & Medication Flow • Oxygen Administration: Know the different devices (nasal cannula, simple mask, Venturi mask, non-rebreather) and their flow rates/FiO2 ranges. • Nebulizer Treatment: Ensure the patient uses a tight-seal mouthpiece or mask. Instruct on slow, deep breaths. Monitor for tachycardia and tremors (common side effects of beta-agonists like albuterol). • ABG Draw: Understand the normal values and how to interpret acidosis/alkalosis, respiratory/metabolic. Apply pressure to the puncture site for at least 5 minutes.

A Word from Your Senior Nurse "In the real world, your brain will be juggling a dozen tasks. That's why the ABC framework is your best friend—it cuts through the noise. The moment you hear 'short of breath' and see a number like 88%, everything else gets mentally 'paused.' Your feet take you to that room first. This isn't just about passing a test; it's about building the clinical instinct that saves lives. When you study, don't just pick answer '2.' Pause and say out loud: 'I'm going to this patient first because their BREATHING is compromised, and that's an ABC priority.' That verbalization builds the neural pathway you'll use at the bedside."
