Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a pediatric pulmonary unit. Your patient, a teenager with CF named Jamie, is anxious, leaning forward, using accessory muscles to breathe. Their cough is weak and non-productive despite feeling "full." SpO2 is 85%, and you hear coarse crackles everywhere.
Nursing Intervention Strategy:- 1Immediate Action (Priority)Explain the need for CPT to Jamie to reduce anxiety and gain cooperation. Perform chest physiotherapy (percussion and vibration) combined with postural drainage positions to target different lung lobes. Have suction equipment ready at the bedside.
- 2Concurrent/Follow-up Actions• After CPT: Encourage deep coughing or use huffing techniques to expectorate loosened secretions. Then apply supplemental oxygen via nasal cannula as ordered, titrating to maintain SpO2 > 92%.
• Assessment: Reassess breath sounds, work of breathing, SpO2, and sputum characteristics (color, amount) after CPT.
• Supportive Care: Position in High Fowler's for comfort and lung expansion. Encourage warm fluids (if not contraindicated) to aid in thinning secretions.
• Medication Administration: Administer prescribed bronchodilators (before CPT) and mucolytics (like dornase alfa).
Patient Safety and Precautions:
• Oxygen Caution: In patients with known or suspected chronic hypercapnia (elevated CO2), use low-flow oxygen (e.g., 1-2 L/min) and monitor for decreased respiratory rate/lethargy, which may indicate CO2 narcosis.
• CPT Contraindications: Do not perform over areas of bleeding, fracture, or recent surgery. Avoid immediately after meals to prevent vomiting/aspiration.
• Infection Control: CF patients often harbor multi-drug resistant bacteria. Practice strict contact precautions as per protocol. CPT equipment should be for individual patient use.
Nursing Procedure & Medication Flow
CPT & Postural Drainage Procedure:
1. Administer bronchodilator (if ordered) 15-30 minutes prior.
2. Position patient to drain specific lung segments (e.g., Trendelenburg for lower lobes).
3. Perform manual percussion (cupped hands) or vibration over the rib cage for 3-5 minutes per area.
4. Encourage deep breathing and controlled coughing/huffing after each position.
5. Collect and document sputum.Medication Point: Pancreatic enzymes (e.g., Creon) must be given with every meal and snack, not on an empty stomach. Do not crush enteric-coated beads.
A Word from Your Senior Nurse
"In the hustle of clinicals and studying, it's easy to see 'low oxygen' and jump to 'give oxygen.' But true nursing judgment is asking *why* the oxygen is low. For this CF patient, the 'why' is a physical plug of mucus. Your hands (doing CPT) are the primary tool to fix that, more immediate than any oxygen tank. Always treat the cause, not just the number on the monitor. This critical thinking is what separates a task-completer from a life-saving nurse and is exactly what the NCLEX is testing."
