Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a orthopedic unit. Your patient, Mr. Johnson, 3 days post total hip replacement, calls out anxiously, "Nurse, I can't breathe!" You find him diaphoretic, clutching his chest, with rapid shallow breaths.
Nursing Intervention Strategy:
1. Immediate Assessment & Action (Within seconds): "Mr. Johnson, I'm here to help you." Call for help (hit the nurse call button or yell for assistance).Raise the head of the bed to 90 degrees (High Fowler's). Apply a non-rebreather mask (NRB) at 10-15 L/min to achieve the highest possible FiO2. Do not leave the patient.
2. Focused Assessment (Concurrent): Check pulse ox (it reads 88%). Auscultate lungs (may hear crackles or be clear due to obstruction). Assess for unilateral leg swelling, pain (signs of DVT source).
3. Collaboration & Preparation: When help arrives, one nurse stays with the patient, another notifies the physician/Rapid Response Team, obtains a STAT EKG to rule out MI, and establishes a second IV line for medication access.
4. Ongoing Monitoring & Care: Continuously monitor vital signs, O2 saturation, and level of consciousness. Stay with the patient to provide reassurance and explain procedures. Prepare for transfer to a higher level of care (e.g., ICU).
Patient Safety and Precautions:
* Do NOT leave the hypoxic patient alone.
* Do NOT lay the patient flat; this worsens dyspnea.
* Caution with Oxygen: Use a NRB for severe hypoxemia. In patients with known CO2 retention (e.g., COPD), be prepared to switch to a Venturi mask or lower flow per protocol if ABG results indicate, but in an acute unknown cause, treat hypoxemia first.
* Anticoagulant Safety: Before administering heparin/enoxaparin, ensure no active bleeding, check for allergies, and have antidotes available (protamine sulfate for heparin).
Nursing Procedure & Medication Flow
Emergency Oxygen Administration:
1. Ensure oxygen source is connected and flowing.
2. Select appropriate delivery device: Non-Rebreather Mask (NRB) for severe hypoxemia (O2 sat < 90%).
3. Set flow rate to 10-15 L/min to ensure reservoir bag remains inflated.
4. Place mask securely over nose and mouth.
5. Reassess O2 saturation and respiratory effort within 1-2 minutes.
Anticoagulant Administration (Post-Stabilization):
* Heparin IV drip: Requires weight-based dosing and continuous infusion pump. Monitor aPTT (Therapeutic range typically 1.5-2.5 x control) every 6 hours initially. Watch for signs of bleeding (gums, urine, stools, injection sites).
* Enoxaparin (Lovenox) SubQ: Given via deep subcutaneous injection in abdomen (avoid 2-inch area around umbilicus). Do not aspirate or massage site. Rotate sites.
A Word from Your Senior Nurse
"Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In clinical practice, recognizing subtle changes in a patient's vital signs early can prevent deterioration. When studying for your boards, don't just memorize — connect everything to a real patient situation and always ask 'why?' That mindset will not only earn you a great score on the NCLEX but will make you a truly confident, professional nurse! In this PE scenario, your quick thinking to sit the patient up and give oxygen buys the critical time needed for the team to mobilize and save a life. Never underestimate the power of those fundamental nursing actions."
