Gas Exchange and Airway Management- Chronic Obstructive Pulmonary Disease (COPD)
Scenario:
David Smith, a 68-year-old retired construction worker with a 40-pack-per-year smoking history, is admitted with increased shortness of breath, productive cough, and fatigue. He reports that he can no longer climb the stairs of his home without resting and has noticed swelling in his ankles. His oxygen saturation is 88% on room air, and arterial blood gases (ABGs) reveal:
- PH 7.33
- PaCO2 58 mmHg
- PaO2 54 mmHg
- HCO3- 30 mEq/L
The nurse notes the use of accessory muscles during respirations and a barrel-shaped chest. The physician orders low-flow oxygen at 2 L/min via nasal cannula, a bronchodilator, and corticosteroid therapy.
Questions:
Q1. Explain the pathophysiology of COPD and how it leads to David's ABG results. Need Assignment Help?
Q2. Describe why is it important to administer low-flow oxygen rather than high concentrations for this patient?
Q3. Identify three nursing interventions to promote effective airway clearance in a patient with COPD.
Q4. Develop a patient education plan focusing on smoking cessation, energy conservation, and infection prevention.
