26
Q

What happens with the lungs during chronic bronchitis?

A

Airways are inflammed and narrowed

Mucus develops and remains in the alveoli and lungs

27
Q

What happens with the lungs during emphysema?

A

Alveolar walls are destroyed which causes the alveoli to “pop” are merge together
Elasticity within the lung tissue is lost
Air becomes trapped in the alveoli

28
Q

What is the number one cause of COPD?

A

Smoking

29
Q

Thick, tenacious sputum
Dyspnea, SOB
Dyspnea on Exertion
Activity intolerance
Prolonged expiration
Increased susceptibility to infection
Mucous plugs develop
Use of accessory muscles to aide in breathing
30
Q

List the signs and symptoms of Emphysema

A 
Chronic cough
Diminished breath sounds
Dyspnea, SOB
Dyspnea on Exertion
Activity intolerance
Barrel Chest
Prolonged expiration
Use of accessory muscles to aide in breathing
31
Q

What happens in the late stages of COPD?

A

Patient has difficulty eating due to severe dyspnea

Patient becomes malnourished and experiences weight loss

32
Q

What diagnostic tests are performed when a patient has an acute exacerbation of COPD or an acute exacerbation of asthma?

A

Chest Xray and/or CT Scan
Complete Blood Count
Sputum Culture
Arterial Blood Gases (hospital setting only)

33
Q

What is the baseline range SpO2 for a patient with COPD?

A

88% - 92%

34
Q

How much baseline supplemental oxygen should a patient with COPD be on?

A

1 to 2 LPM

35
Q

If a patient with COPD is having an acute exacerbation, can they be placed on more than the recommended 1 to 2 LPM of supplemental oxygen?

A

Yes. However, provider should decrease the oxygen as quickly as possible with the patient keeping SpO2 levels greater than or equal to 88%

36
Q

Is a patient with COPD required to be on oxygen?

A

No. If the patient can maintain appropriate oxygen saturations (88-92%) without O2, there is no need to be placed on the oxygen

37
Q

If the student nurse knows a patient has a history of COPD and their assessment yields an O2 reading of 90%, should they be concerned?

A

Yes, always concerned if O2 is less than 94%. Performed appropriate assessments, interventions, reassessments and reporting to instructor!

38
Q

What is the goal of COPD treatment?

A

To reduce symptoms, slow progression and reduce the amount of exacerbations
Increase quality of life

39
Q

List therapeutic interventions for COPD

A

Stop smoking
Provide 1 to 2 LPM oxygen if necessary (if SpO2 <88%)
Increase activity as tolerated
Administer medications as necessary
Encourage vaccinations; pneumococcal and influenza
Encourage a diet high in protein and high in fat
Teaching breathing exercises

40
Q

What medication drug class should be avoided when a patient has COPD?

A

Antitussive Agents
These medications reduce coughing

Want to promote coughing in the COPD patient to expectorate secretions

41
Q

Why does a patient with COPD have an ineffective airway clearance? How can the nurse aide with this issue?

A

Airway is congested with mucus
The cough is weak and congested
Crackles are present

Nurse should encourage and increase fluids

42
Q

What can the nurse do when a patient has an ineffective breathing pattern?

A

Encourage pursed lip and/or diaphragmatic breathing

43
Q

What is occurring within the lungs when a patient has asthma?

A

Airways are chronically inflammed
Bronchioles are spasming
Airways are narrow
Air gets trapped

44
Q

List the causes (etiology) of asthma

A

Heredity/Genetics
Airborne allergies
Pollution
Smoking

45
Q

List triggers of asthma

A

They’re different for every person. Common triggers include:
Smoking, second hand smoke
Allergens such as pollen, pets, environmental triggers
Respiratory infection
Sinusitis
Stress
Medications (non specific beta one blockers)

46
Q

List signs and symptoms of asthma

A 
Dyspnea
Tachypnea
Wheezing
Chest tightness
Cough
Sputum
Use of accessory muscles
47
Q

The nurse knows what is happening if the patient with asthma has absent lung sounds?
What medication should be given?
What lung sounds would be heard next?

A

Bronchioles are completely constricted, minimal air flow, emergency!
Medication: beta two adrenergic agonist to promote bronchodilation
After the medication is given, should hear wheezing. Bronchioles are beginning to open back up, but they’re still very narrow

48
Q

During acute exacerbations of asthma or COPD, what therapeutic interventions will the nurse implement?

A

High Fowlers position
Pursed lip breathing
Supplemental O2 if necessary
Nebulized mist treatments (beta two agonists)
Possible corticosteroid treatment to reduce inflammation

49
Q

What is the purpose of the peak flow meter? Why is it useful?

A

To measure the peak expiratory flow

Measurement is useful in detecting changes in airways, this could signal worsening respiratory symptoms

50
Q

What is the purpose of tracking peak flow measurements on the chart?

A

So the patient and provider can see if current therapy is working, if it is effective, or if it needs to be adjusted

51
Q

What does the green zone on the peak flow chart mean?

A

Green = Good

No changes made in treatment

52
Q

What does the yellow zone on the peak flow chart mean?

A

Yellow = Caution
Asthma is beginning to worsen
Use rescue inhaler to help improve s/s
Patient needs to see provide if yellow zone is frequently occurring

53
Q

What does the red zone on the peak flow chart mean?

A

Red = Get Help!
Less than 50% of personal best
Use rescue inhaler, go get help

54
Q

What is the difference between daily/maintenance medications and rescue medciations?

A

Daily/maintenance medications are taken every day to improve symptoms long-term, they are not used for immediate relief or acute issues
Rescue medications are taken when symptoms worsen and immediate relief is needed

55
Q

What is a pulmonary embolism?

A

Blood clot within the pulmonary artery

56
Q

What is the most common cause of pulmonary embolism development?

A

A deep vein thrombosis (DVT) that dislodged and traveled to the pulmonary artery

57
Q

How is a pulmonary embolism prevented?

A

Prevent development of a DVT; move/ambulate regularly, prophylactic DVT treatment if the patient is hospitalized/immobile

58
Q

How is a DVT treated?

A

With anticogulant medication

59
Q

List the signs and symptoms of a pulmonary embolism

A

Respiratory distress; suddent onset dyspnea, tachypnea, anxiety, decreased oxygen saturation

Tachycardia
Cough
Crackles

60
Q

How can a pulmonary embolism be diagnosed?

A

If a D-Dimer is elevated above 500 ng/mL, a CT Angiogram of the Chest will be ordered

If a patient cannot receive a CTA, a ventilation perfusion scan will be performed

61
Q

List therapeutic interventions for a pulmonary embolism

A

High Fowlers
Oxygen (Non-Rebreather at 15LPM if severe respiratory distress present)
Anticoagulant medication (heparin or lovenox)

62
Q

List signs and symptoms of acute respiratory distress

A 
Tachypnea
Dyspnea
Labored breathing
Accessory muscle use
Adventitious / Absent lung sounds
Decreasing oxygen sats
Tachycardia
HTN
Restlessness
Confusion
Lethargy
63
Q

What can the nurse do if a patient presents with respiratory distress?

A 
Place in high Fowlers or tripod position
Apply oxygen; non rebreather, 15 LPM
Encourage pursed lip breathing
Administer medications ordered (short acting bronchodilators, corticosteroids)
Assist in intubation
