  • chemo
  • biological targeted therapy
49
Q

overall nursing mgt of pt with lung cancer

A

(1) effective breathing patterns, (2) adequate airway clearance, (3) adequate oxygenation of tissues, (4) minimal to no pain, and (5) a realistic attitude toward treatment and prognosis.

50
Q

pneumothorax

A

presence of air in the pleural space. As a result of the accumulation of air, there is partial or complete collapse of the lung.

51
Q

closed pneumothroax

A

no associated external wound. The most common form is a spontaneous pneumothorax, which is accumulation of air in the pleural space without an apparent antecedent event. It is caused by the rupture of small blebs (air-filled alveolar dilations <1 cm in diameter on the edge of the lung at the apex of the upper lobe or superior segment of the lower lobe) on the visceral pleural space.

52
Q

open pneumothorax

A

air enters the pleural space through an opening in the chest wall

53
Q

tension pneumothorax

A

a pneumothorax with rapid accumulation of air in the pleural space causing severely high intrapleural pressures with resultant tension on the heart and great vessels. It may result from either an open or a closed pneumothorax.

54
Q

hemothorax

A

accumulation of blood in the intrapleural space. It is frequently found in association with open pneumothorax and is then called a
hemopneumothorax.

55
Q

chylothorax

A

lymphatic fluid in the pleural space due to a leak in the thoracic duct. Causes include trauma, surgical procedures, and malignancy.

56
Q

flail chest

A

results from multiple rib fractures, causing an unstable chest wall. The affected (flail) area will move paradoxically to the intact portion of the chest during respiration. During inspiration, the affected portion is sucked in, and during expiration, it bulges out. This paradoxical chest movement prevents adequate ventilation of the lung in the injured area.

57
Q

flail chest therapy

A

adequate ventilation, administration of humidified O2, careful administration of crystalloid IV solutions, and pain control.

58
Q

monitering chest tubes

A

evaluate if the chest drainage is successful by observing for tidalling in the water-seal chamber, listening for breath sounds over the lung fields, and measuring the amount of fluid drainage.

59
Q

thorocotomy

A

considered major surgery because the incision is large, cutting into bone, muscle, and cartilage. The two types of thoracic incisions are median sternotomy, performed by splitting the sternum, and lateral thoracotomy.

60
Q

pleural effusion

A

collection of fluid in the pleural space. It is not a disease but rather a sign of a serious disease.

61
Q

empyema

A

pleural effusion that contains pus

62
Q

pleurisy

A

inflammation of the pleura. The most common causes are pneumonia, TB, chest trauma, pulmonary infarctions, and neoplasms.

63
Q

atelectasis

A

complete or partial collapse of a lung or segment of a lung that occurs when the alveoli become deflated.

64
Q

idiopathic pulmonary fibrosis

A

characterized by scar tissue in the connective tissue of the lungs as a sequel to inflammation or irritation.

65
Q

sarcoidosis

A

chronic, multisystem granulomatous disease of unknown cause that primarily affects the lungs. The disease may also involve the skin, eyes, liver, kidney, heart, and lymph nodes.

66
Q

pulmonary embolism

A

blockage of pulmonary arteries by a thrombus, fat, or air emboli, or tumour tissue.

67
Q

common risk factors for pulmonary embolism

A

immobility, surgery within the last 3 months (especially pelvic and lower extremity surgery), stroke, paresis, paralysis, history of DVT, malignancy, obesity in women, heavy cigarette smoking, and hypertension.

68
Q

objectives of tx of pulmonary embolism

A

(1) prevent further growth or multiplication of thrombi in the lower extremities, (2) prevent embolization from the upper or lower extremities to the pulmonary vascular system, and (3) provide cardiopulmonary support if indicated.

69
Q

pulmonary hypertension

A

severe and progressive disease. It is characterized by mean pulmonary arterial pressure greater than 25 mm Hg at rest (normal 12 to 16 mm Hg) or greater than 30 mm Hg with exercise in the absence of a demonstrable cause.

70
Q

cor pulmonale

A

enlargement of the right ventricle secondary to diseases of the lung, thorax, or pulmonary circulation.

71
Q

most common cause of cor pulmonale

A

COPD

72
Q

4 types of lung transplant

A

single lung transplant, bilateral lung transplant, heart-lung transplant, and transplant of lobes from living related donor.

73
Q

asthma

A

chronic inflammatory lung disorder of the airways that results in recurrent episodes of airflow obstruction, but is usually reversible. Inflammation causes varying degrees of obstruction in the airways, which leads to recurrent episodes of wheezing, breathlessness, sensation of chest tightness, and cough, particularly at night and in the early morning.

74
Q

hallmarks of asthma

A

airway inflammation, airway hyper responsiveness

75
Q

severe acute asthma complications

A

pneumothorax, pneumomediastinum, acute cor pulmonale with right ventricular failure, and severe respiratory muscle fatigue that leads to respiratory arrest (which can be fatal).

76
Q

two main features in diagnosis of asthma

A

symptoms and variable airflow obstruction.

77
Q

COPD

A

preventable and treatable disease state characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases, primarily caused by cigarette smoking.

78
Q

COPD s&s

A

dyspnea, difficulty breathing, or shortness of breath and limitations in activity. Symptoms are usually insidious in onset and progressive. Dyspnea is the subjective experience of shortness of breath and is the most disabling symptom in COPD.

79
Q

emphysema

A

describes only one pathological change present in COPD: destruction of the alveoli.

80
Q

chronic bronchitis

A

the presence of chronic productive cough for 3 months in 2 successive years, is a useful epidemiological term but does not convey how airway limitation severely affects morbidity and mortality in patients with COPD.

81
Q

α1-Antitrypsin (AAT) deficiency

A

autosomal recessive disorder, is currently the only known genetic abnormality that leads to COPD.

82
Q

complications of COPD

A
  • cor pulmonale
  • acute exacerbation
  • anxiety & depression
83
Q

primary goals of care for pt with COPD

A

(1) prevent disease progression (smoking cessation), (2) reduce the frequency and severity of exacerbations, (3) alleviate breathlessness and other respiratory symptoms, (4) improve exercise tolerance and daily activity, (5) treat exacerbations and complications of the disease, (6) improve health status and quality of life, and (7) reduce the risk of mortality

84
Q

lung volume reduction surgery

A

reduce the size of the lungs by removing about 20% to 35% of the most diseased lung tissue so the remaining healthy lung tissue can perform better.

85
Q

lung transplantation

A

pts with very advanced copd

86
Q

pursed lip breathing

A

technique that is used to prolong exhalation, prevent bronchiolar collapse and air trapping, and assist with dyspnea. Exhalation should be at least three times longer than inhalation.

87
Q

cystic fibrosis

A

autosomal recessive, multisystem disease characterized by altered function of the exocrine glands primarily involving the lungs, pancreas, and sweat glands.

88
Q

main objectives of therapy in CF are

A

(1) promote clearance of secretions, (2) control infection in the lungs, and (3) provide adequate nutrition.

89
Q

nursing care for pt with CF

A

revolves around the diagnoses of ineffective airway clearance, impaired gas exchange, ineffective breathing patterns, imbalanced nutrition: less than body requirements, and ineffective coping.
