Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 45, was admitted yesterday for cellulitis. He has a history of DVT. He calls you to his room stating, "I can't catch my breath, and my chest hurts!"
Nursing Intervention Strategy:1. Immediate Assessment (ABCs): Upon entering the room, your first visual and auditory assessment notes severe respiratory distress. Your first action is to apply a pulse oximeter. It reads 78%. You immediately call for help and apply a non-rebreather mask at 15 L/min to deliver high-concentration oxygen.2. Comprehensive Assessment & Monitoring: While oxygen is being administered, you quickly assess airway patency, auscultate lung sounds (may hear crackles or be clear), check vital signs (BP, HR, RR), and assess for jugular vein distension. You stay with the patient to monitor for changes.3. Communication & Preparation: Inform the rapid response team or physician immediately. Anticipate orders for stat labs (ABG, D-dimer), ECG, and a CT scan. Prepare emergency equipment (crash cart, intubation tray) at the bedside.4. Ongoing Care & Treatment: Once the patient is stabilized, administer anticoagulant therapy as ordered (e.g., IV heparin drip). Monitor for bleeding complications. Provide reassurance and explain procedures to reduce anxiety.
Patient Safety and Precautions:• Oxygen Safety: Ensure oxygen delivery equipment is functioning. A non-rebreather mask must have the reservoir bag inflated.• Falls Risk: A hypoxic and anxious patient is at high risk for falls. Keep the bed in low position, side rails up, and call light within reach. Do not leave the patient alone.• Medication Safety: When anticoagulants are started, double-check the dosage and infusion rate. Monitor PTT (Partial Thromboplastin Time) for heparin or anti-Xa levels for LMWH (Low Molecular Weight Heparin). Assess for signs of bleeding (gums, urine, stool, injection sites).
Nursing Procedure & Medication Flow
Procedure: Administering High-Flow Oxygen via Non-Rebreather Mask1. Explain the procedure to the patient briefly: "Mr. Johnson, I'm putting this mask on to give you more oxygen to help you breathe."2. Connect the mask to the oxygen flowmeter and set to 15 liters per minute.3. Occlude the valve on the mask with your finger to inflate the reservoir bag.4. Place the mask over the patient's nose and mouth, securing the elastic strap.5. Ensure the reservoir bag does not completely deflate during inspiration (if it does, increase flow rate).6. Continuously monitor SpO2, respiratory rate, and work of breathing.
Medication: IV Heparin Drip• Action: Prevents extension of the existing clot and formation of new clots.• Nursing Responsibility: Administer via an IV infusion pump for precise control. The dose is titrated based on PTT results (typically target 1.5-2.5 times the control).• Key Monitoring: PTT levels every 6 hours initially; monitor for HIT (Heparin-Induced Thrombocytopenia) (check platelet counts); assess for bleeding.
A Word from Your Senior Nurse
"In the chaos of a patient suddenly struggling to breathe, it's easy to feel overwhelmed. Your brain might jump to the chest pain, the swollen leg, or the fast heart rate. But train yourself to have a laser focus: Airway, Breathing, Circulation. That pulse ox reading is your best friend—it gives you a number that tells you exactly how bad the 'Breathing' problem is. A saturation in the 70s is a five-alarm fire. Your immediate job isn't to diagnose the PE (though you're thinking it), it's to prevent respiratory arrest. Getting that oxygen on is the most powerful nursing intervention you can do in those first seconds. Everything else—calling the doctor, getting the heparin ready, comforting the family—flows from that one, critical, life-saving action. Remember this on the NCLEX and in practice: stabilize first, investigate and treat second."
