Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Jones, 68, post-operative day 3 from a total knee replacement, suddenly complains of sharp chest pain that worsens with a deep breath and severe shortness of breath. His vital signs are: HR 122, BP 98/60, RR 28, SpO2 89% on room air. He is anxious and diaphoretic.
Nursing Intervention Strategy:- 1Assessment & Immediate Action (ABCs)Upon hearing "chest pain" and "shortness of breath," immediately assess airway patency and respiratory effort. Check SpO2. Your first actions are to call for help, sit the patient upright (High Fowler's), and apply a non-rebreather mask at 10-15 L/min to achieve SpO2 > 90%.
- 2Secondary Assessment & MonitoringWhile oxygen is on, perform a focused assessment: auscultate lung sounds (may be clear or have crackles), assess for unilateral leg swelling (DVT), obtain a full set of vitals, and connect to cardiac monitoring (PE can cause tachycardia and right heart strain patterns).
- 3Communication & PreparationInform the provider STAT of your findings and actions. While awaiting orders, prepare for next steps: ensure IV access is patent (if not, insert a large-bore IV), have emergency equipment nearby, and prepare the patient mentally for potential transfer to ICU or for a CT scan once stable.
Patient Safety and Precautions:
* Do not leave the unstable patient alone.
* Contraindication: Avoid aggressive fluid resuscitation unless specifically ordered, as it can worsen right heart strain in PE.
* Medication Caution: If anticoagulants (like heparin) are ordered, verify there are no contraindications (active bleeding, recent surgery, history of HIT). Monitor PTT (Partial Thromboplastin Time) or anti-Xa levels per protocol.
Nursing Procedure & Medication Flow
Oxygen Administration via Non-Rebreather Mask:
1. Select correct device (mask with reservoir bag).
2. Set oxygen flow to 10-15 L/min to ensure the reservoir bag remains inflated.
3. Place mask securely over nose and mouth.
4. Reassess SpO2 within 5 minutes and titrate oxygen to maintain target saturation.Anticoagulant (Heparin) Initiation:
1. Verify provider order and check baseline labs (PT/INR, PTT, platelets, Hgb/Hct).
2. Calculate correct dose based on weight-based protocol.
3. Administer IV bolus (if ordered) followed by continuous IV infusion via an infusion pump.
4. Monitor PTT 6 hours after initiation and per protocol, adjusting infusion rate as ordered.
5. Assess for bleeding: gums, urine, stool, injection sites, bruising.
A Word from Your Senior Nurse
"In the rush of a potential PE, it's easy to get caught up in the 'what ifs' and jump straight to calling for tests or medications. But your most powerful tool is your foundational nursing judgment: ABCs. By first ensuring your patient can breathe, you're buying the critical time needed for diagnostics and treatment to work. On the NCLEX and at the bedside, this systematic approach saves lives. Remember: Fix the problem that will kill the patient right now first. Everything else comes second."
