WEEK 4 COPD Flashcards
What causes the ongoing inflammation of COPD?
Foreign substances
What is the term for someone who has physiologically adapted over time and learned to live with higher levels of CO2 in their blood and lower levels of O2 in their blood?
True CO2 retainer
What is the term for a changed mechanism to trigger breathing, so that the patient now breathes when their blood O2 levels are low?
Hypoxic drive
What are 3 main nursing diagnoses for COPD?
- Ineffective breathing pattern
- Ineffective gas exchange
- Ineffective airway clearance
What does wheezing indicate?
Narrowed airways
What are 3 potential causes for narrowed airways?
- Bronchospasm
- Impaired gas exchange
- Sputum that cannot be cleared
What is the term for in-drawing on inspiration at junction of anterior base of neck and above clavicle?
Supraclavicular notching
What are 3 things seen on x-ray that may indicate COPD?
- barrel ribcage
- flattened diaphragm
- opacities through bronchi
When a client has ineffective breathing pattern, how often should vitals be monitored, and how often should the lungs be auscultated?
q15min, and q1h
What are 5 nursing interventions for a client with COPD experiencing insufficient gas exchange?
- Monitor vitals and LOC q15min
- Initiate O2 at 1L to achieve SpO2 88-90
- Recheck SpO2 in 5 min, increase to 2L if necessary
- Admin nebulizers (ventrolin, atrovent)
- Inform physician and RT to order ABG
What is the defining characteristic of uncomplicated respiratory acidosis?
Normal bicarb, as the kidneys have not compensated by retaining HCO3
What is the defining characteristic of partially compensated respiratory acidosis?
Increasing bicarb, as kidneys are compensating for increasing levels of carbonic acid by retaining HCO3- and secreting H+ ions
What is the defining characteristic of compensated respiratory acidosis?
Client achieves normal baseline of elevated paCO2, decreased pH, and elevated HCO3-.
What are 3 factors related to COPD that predispose patients to infection?
- Excess sputum
- Corticosteroids (immunosuppression)
- Old age, poor diet
Which lab test shows the presence of chronic inflammation in the body?
Erythrocyte sedimentation rate (ESR)
