Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a medical-surgical unit. Your patient, Mr. Jones, a 55-year-old with a history of asthma, calls you to the room stating he "can't catch his breath." You find him leaning forward, using his neck and shoulder muscles to breathe. His lips appear slightly dusky.
Nursing Intervention Strategy:- 1Immediate Assessment & ActionWhile calling for help, apply a nasal cannula at 2 L/min and place the patient on a pulse oximeter and cardiac monitor. Your primary goal is to correct the SpO₂.
- 2Simultaneous InterventionsWhile oxygen is flowing, quickly position the patient in high Fowler's to maximize lung expansion. Prepare the nebulizer with the prescribed bronchodilator (e.g., albuterol). Encourage slow, pursed-lip breathing to help keep airways open longer during exhalation.
- 3Ongoing Monitoring & EvaluationContinuously monitor SpO₂, respiratory rate and effort, breath sounds, and heart rate. Assess for improvement or signs of deterioration (e.g., decreasing level of consciousness, fatigue). Document everything meticulously.
Patient Safety and Precautions: In asthma, high-flow oxygen is generally safe. However, always be aware of the patient's history. If there is a co-diagnosis of COPD, titrate oxygen carefully to the target SpO₂ of 88-92% to avoid oxygen-induced hypercapnia (retention of CO₂). Never withhold oxygen from a hypoxemic patient due to fear of hypercapnia; instead, monitor closely.
Nursing Procedure & Medication Flow
Oxygen Administration via Nasal Cannula:
1. Explain the procedure to the patient.
2. Set the flowmeter to the prescribed rate (e.g., 2 L/min).
3. Place the prongs in the patient's nostrils, loop the tubing over the ears, and adjust the slider under the chin.
4. Ensure the oxygen is humidified if flow is >4 L/min for comfort.
5. Place "Oxygen in Use" signs and enforce fire safety precautions.Nebulizer Medication Administration:
1. Assemble the nebulizer cup and connect it to the air/oxygen source.
2. Pour the prescribed medication (e.g., albuterol 2.5 mg) into the cup.
3. Connect the mouthpiece or mask.
4. Turn on the compressor. Instruct the patient to take slow, deep breaths through the mouthpiece.
5. Treatment typically lasts 5-15 minutes until the medication is fully aerosolized.
A Word from Your Senior Nurse
"In the rush of an emergency, your training kicks in. Remember your ABCs like a mantra. Seeing a patient struggle to breathe is scary—for them and for you. Your calm, decisive action to give oxygen first provides immediate relief and buys time for other treatments to work. In clinicals and on the NCLEX, always ask yourself: 'What will kill the patient first?' That's your priority. This mindset saves lives."
