Q

A patient with long-term COPD is diagnosed with cor pulmonale. Which of the following findings should the nurse expect?

A. Crackles in the lower lobes
B. Peripheral edema and jugular vein distention
C. Elevated blood pressure and bradycardia
D. Wheezing with inspiration and expiration

A

Answer: B. Peripheral edema and jugular vein distention

Rationale: Cor pulmonale is right-sided heart failure caused by pulmonary hypertension from chronic lung diseases like COPD. Peripheral edema and jugular vein distention are classic signs of right-sided heart failure.

Q

A nurse is assessing a patient with COPD. Which complication should the nurse monitor for if the patient develops pulmonary hypertension?

A. Left-sided heart failure
B. Right-sided heart failure
C. Myocardial infarction
D. Pulmonary embolism

A

Answer: B. Right-sided heart failure

Rationale: Cor pulmonale, or right-sided heart failure, is a complication of COPD caused by increased pressure in the pulmonary arteries from long-term lung damage. This condition leads to hypertrophy and failure of the right ventricle.

Q

COPD 4 Most Common Risk Factors

A
  • Tobacco Smoke: Accounts for 80-90% of cases
  • Passive Smoking: Includes second and third-hand smoke
  • Increased age
  • Asthma
  • Occupational exposures
  • Air pollution
  • genetics abnormalities: Alpha-1 deficiency
18
Q

Most COMMON S/S of PROGRESSED COPD
(not seen in Asthma)

List 9

A
  • Chronic cough
  • Sputum production
  • Dyspnea @ rest
  • Thin with Barrel Chest
  • Accessory muscle use
  • Polycythemia due to chronic hypoxia
  • Cyanosis and clubbing of fingers
  • Musculoskeletal wasting
  • Depression
19
Q

Which device would the nurse teach a patient with COPD to blow into to loosen pulmonary secretions?

A. Incentive spirometer
B. Peak flow meter
C. Flutter valve device
D. Holding chamber (spacer)

A

C. Flutter valve device
(blow air into device= causes vibrations to release secretions)

20
Q

5 Diagnostic studies for COPD

A
  1. Pulmonary Function Tests
  2. Spirometry: assess lung function and diagnose COPD or asthma
  3. ABG’s: evaluate oxygen and carbon dioxide levels in the blood
  4. Chest XRay: rule out other issues
  5. Echocardiogram: evaluates function of ventricles/cor pulmonale
21
Q

ABG lab results for COPD in the LATE stages?

A
  • Low PaO2,
  • elevated PaCO2
  • low-normal pH
  • increased HCO3: body’s way of compensating
22
Q

If patient is NOT a smoker, what diagnostic tests will be anticipated?

A

Alpha-1 Antitrypsin Levels: To check for deficiency, especially if there are symptoms of lung disease.

23
Q

2 RESPIRATORY complications of COPD

A

Respiratory insufficiency and respiratory failure

24
Q

Define:

Atelectasis

A

partial or complete collapse of a lung or a section of a lung due to alveoli becoming deflated or filled with fluid.

25
Q

Define:

Pneumothorax

A

condition where air leaks into the space between the lung and the chest wall, causing the lung to collapse partially or completely.

26
Q

Which is a type of obstructive airway disease that causes gradual destruction of the alveoli, causing shortness of breath?

A. Chronic bronchitis
B. Cor pulmonale
C. Asthma
D. Emphysema

A

D. Emphysema

27
Q

Which test might be ordered to diagnose COPD or to track the effectiveness of treatment?

A. Echocardiogram
B. Pulmonary Function Test
C. Arterial Blood Gas
D. Chest x-ray

A

B. Pulmonary Function Test

(all can be done but MOST used for lung funtion is B)

28
Q

What is the most cost-effective intervention to reduce the risk of developing COPD?

A

Smoking Cessation:

29
Q

Medical Management for COPD

List 7

A
  • Vaccines – (flu, pneumonia, Covid)
  • Bronchodilators: SAMA/LAMA, SABA/LABA
    -Often used in combination with corticosteroids
  • Alpha1-antitrypsin therapy
  • Antibiotics
  • Mucolytic agents
  • Antitussive agents: suppress coughing
  • Vasodilators
30
Q

MED used for COPD Exacerbations ONLY

A

Roflumilast (Daliresp)- (PDE4 inhibitor) – reduces risks for exacerbations

31
Q

Name 2 palliative surgical procedures for COPD
(do not cure)

A

1.Bullectomy
2.Lung Volume Reduction Surgery

32
Q

What is done in bullectomy?

A
  • Bullae are enlarded spaces that do not contribute to ventilation and take up space in thorax.
  • These are surgically removed.
33
Q

What is done in Lung Volume Reduction Surgery

A
  • Surgically removes lung tissue allowing functional tissue to expand, resulting in improved elastic recoil, decreased dyspnea, and improved lung function
  • option for patients with advanced or end-stage COPD
34
Q

The ONLY cure for COPD

A

Lung Transplantation
* Costly & limited by shortage of donor organs

35
Q

How does COPD lead to chronic HIGH levels of Carbon Dioxide (CO2)?

A
  • In COPD patients, chronic high levels of CO2 cause the body to adapt to this abnormal condition.
  • Over time, the brain becomes less sensitive to changes in CO2 levels.
  • As a result, even when CO2 levels rise, the body does not respond as strongly or quickly as it normally would.
36
Q

Should you withold oxygen from a hypoxic COPD patient?

A

You should NEVER withhold oxygen from a COPD patient if they are hypoxic, but use it cautiously

37
Q

Why is oxygen therapy a concern for COPD patients?

A

COPD patients have a different drive to breathe than normal people.
* Oxygen binds to hemoglobin more easily than carbon dioxide.
* Administering excessive oxygen to COPD patients can lead hemoglobin to release carbon dioxide to pick up oxygen.
* This results in a spike in CO2 levels, potentially worsening the patient’s condition.

38
Q

What is considered a normal O2 saturation range for COPD patients?

A

88-92% may be normal and acceptable for them

39
Q

Define:

It measures the amount of oxygen dissolved in the blood and is an important indicator of how well oxygen is being transported from the lungs to the bloodstream

A

PaO2

40
Q

CO2 normal levels

A

35-45 mmHg
(assess respiratory function and metabolic status- too much = Acid in body)

41
Q

Pt education for COPD patients

List 5 (most important)

A
  • Breathing and airway clearance exercises
  • Activity pacing/energy conservation
  • Oxygen therapy: no smoking
  • Nutritional therapy: low carb, high calories, high protein- are needed bc they are thin, not so much fluids.
  • Coping measures – psychosocial/emotional
42
Q

REview:

4 COPD Complications

A
  1. COPD Exacerbations
  2. Cor Pulmonale: diuretics, O2, antbx, bronchodilators, meds
  3. Acute Respiratory Failure
