Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 68, post-knee surgery 5 days ago, suddenly complains of sharp chest pain that worsens with deep breaths and severe shortness of breath. He is anxious, tachycardic (HR 122), tachypneic (RR 28), and his SpO2 is 88% on room air. A stat CT angiogram confirms a pulmonary embolism.
Nursing Intervention Strategy:1. Immediate Action (Seconds to Minutes): Stay with the patient. Call for help (using the call bell/phone). Apply a non-rebreather mask (NRB) at 10-15 L/min to achieve SpO2 > 92%. Elevate the head of the bed to ease breathing. Connect to continuous cardiac and pulse oximetry monitoring.2. Rapid Assessment & Communication (Minutes): Perform a focused assessment: breath sounds (may hear crackles or be clear), check for jugular venous distension (JVD), assess for signs of shock (cool/clammy skin, hypotension). Immediately report findings to the provider, stating, "Confirmed PE, patient is hypoxic and tachycardic."3. Preparation for Emergency Interventions: Ensure two large-bore IV lines are patent. Have the emergency cart (crash cart) nearby. Anticipate and prepare for provider orders: stat labs (ABG, D-dimer, troponin), IV heparin drip, or potential transfer to ICU for thrombolytic therapy.4. Ongoing Monitoring & Support: Reassure the patient. Monitor for deterioration: worsening hypoxia, hypotension, syncope, or new chest pain—signs of a massive PE. Once stable, begin planning for education on anticoagulants (like Warfarin or DOACs) and lifestyle modifications.
Patient Safety and Precautions:• Oxygen Safety: Use caution with oxygen in patients with severe COPD who may be CO2 retainers, but in an acute PE, treating life-threatening hypoxia takes precedence.• Falls Risk: The patient is at high risk for syncope. Keep the bed in low position with side rails up. Do not leave the patient unattended.• Bleeding Risk: Once anticoagulation starts, implement bleeding precautions: avoid IM injections, use soft-bristle toothbrush, monitor for bruising, hematuria, or melena.
Nursing Procedure & Medication Flow
Procedure: Administering High-Flow Oxygen via Non-Rebreather Mask1. Explain the procedure quickly to the anxious patient: "Mr. Johnson, I'm putting this mask on to help you get more oxygen and ease your breathing."2. Select a properly sized mask. Ensure the reservoir bag is inflated by occluding the one-way valve and allowing it to fill with oxygen before placing it on the patient.3. Set the oxygen flowmeter to 10-15 L/min. The reservoir bag should remain at least 1/3 to 1/2 full during inspiration.4. Place the mask securely over the patient's nose and mouth, adjusting the nose bridge and elastic strap for a snug but comfortable fit.5. Key Point! Continuously monitor the patient's response: SpO2, respiratory rate, work of breathing, and level of consciousness. Document the intervention and response.
Medication: Anticipating Anticoagulant (Heparin) Drip• Action: Prevents extension of the existing clot and formation of new clots.• Nursing Responsibility: Administer via an IV infusion pump. Double-check the dosage and concentration with another nurse. Monitor aPTT (activated Partial Thromboplastin Time) per protocol (typically 6 hours after initiation and after dose changes). Therapeutic range is usually 1.5-2.5 times the control value.• Calculation Alert: Be proficient in calculating drip rates (mL/hr) based on units/kg/hr ordered and the concentration of the heparin solution.
A Word from Your Senior Nurse
"In the rush of an emergency like this, it's easy to feel overwhelmed. Remember your training: ABCs first, everything else second. Your quick action to give oxygen can literally save a life by buying time for definitive treatment. On the NCLEX and in real life, they are testing your clinical judgment—can you see past the 'important' tasks to identify the 'critical' one? Always ask yourself: 'What will kill my patient first?' In this case, it's lack of oxygen. Master this thought process, and you'll navigate both exam questions and real crises with confidence."
