decreased activity intolerance ineffective airway clearance impaired gas exchange ineffective health management
41
fraction of inspired oxygen [FiO2]
more aggressive respiratory support measure, administration of high concentrations of oxygen
42
aspiration
inhalation of foreign material into the lungs leads to inflammatory reaction, hypoventilation, and ventilation-perfusion mismatch
43
aspiration can cause
broncho or lobar pneumonia
44
aspiration prevention
swallowing screen HOB elevated (intubated- endotracheal cuff elevated) avoid stimulation of gag reflex with suctioning check placement of tube feeding soft diet, small bites, no straws
45
pulmonary tuberculosis s/s
low-grade fever cough, nonproductive or mucopurulent, hemoptysis, NIGHT SWEATS , fatigue, weight loss
46
pulmonary tuberculosis tranmission
Spreads by airborne transmission through droplets then moves to other parts of the body such as the kidneys, bones, and cerebral cortex.
47
TB diagnostic tests
history and physical TB skin test: Mantoux method TB blood test sputum culture sputum testing
48
TB test and what are they looking for
Mantoux method (positive= palpable, a bump)
49
primary concern for medical management tof tuberculosis
drug resistance
50
treatment of TB and drugs to treat it
anti-TB agents for 6-12 month Isoniazid
51
treatment of TB and drugs to treat it
anti-TB agents for 6-12 month Isoniazid Rifampin rifapentine pyrazinamide ethambutol isoniazid + rifampin
52
nursing management of TB
promoting airway clearance (copious secretion interfere with gas exchange) promoting adherence to treatment regimen promote activity and adequate nutrition prevent transmission of TB (N95)
53
lung abscess
localized collection of pus caused by microbial infection
54
lung abscess is generally caused by
aspiration of anaerobic bacteria
55
lung abscess physical exam
dullness on percussion decreased or absent breath sounds with an intermittent pleural friction rub on auscultation
56
pleural friction rub
grating or cracking sound
57
lung abscess can lead to
empyema (pocket of pus) and bronchopleural fistula (with collection of fluid in the pleura)
58
lung abscess s/s
mild productive cough to acute illness, FOUL-SMELLING SPUTUM, leukocytosis, pleurisy, dyspnea, weakness, anorexia, an d weight loss
59
management tof lung abscess
chest physiotherapy to drain excess fluid
60
sarcoidosis
type of interstitial lung disease that is also an inflammatory, multi-system, granulomatous disease of unknown eitology
61
walking pneumonia
mycoplasma pneumoniae
62
correct use of incentive spirometer
the patient inhales slowly from the device until no longer able and then holds breath for 6 seconds and exhales
63
vancomycin can cause
ototoxicity
64
pluerisy
Inflammation of both layers of pleurae Key characteristic of pleuritic pain is its relationship to respiratory movement
65
plueral effusion
fluid collection in pleural space usually secondary to heart failure, TB, Pneumonia, pulmonary infections
66
empyema
accumulation of thick purulent fluid in pleural space often with fibrin development, patient will be acutely ill sings and symptoms similar those of acute pneumonia
67
pulmonary edema
68
pleural effusion s/s
fever, chills, pleuritic pain, dyspnea decreased or absent breath sounds, decreased fremits and dull/flat sound on percussion
69
empyema is a complication of
bacterial pneumonia or a lung abscess
70
acute respiratory failure
deterioration of the gas exchange of the lungs and indicates their failure to provide adequate oxygenation of ventilation for the blood
71
visceral pleura
membranes covering the lungs
72
parietal pleura
membranes covering the chest wall
73
Acute respiratory failure causes
hypoxemia (decrease in arterial oxygen) hypercapnia (increase in arterial CO2) respiratory acidosis impaired ventilation and perfusion mechanisms
74
early and late signs of acute respiratory failure
early: restlessness, tachycardia, hypertension, fatigue, headache late: confusion, lethargy, central cyanosis, diaphoresis, respiratory arrest
75
clinical manifestations of acute respiratory failure
accessory muscles, decreased breath sounds
76
medical and nursing management of ARF
intubation, mechanical ventilation (depending on severity) enteral feedings reduce anxiety
77
endotracheal intubation (why do we use the oral route?)
involves passing an endotracheal intubation tube through the nose or mouth into the trachea oral intubation is preferred because its less risk for infection and trauma, and can accommodate a larger diameter
78
Intubation provides...
a patent airway when the patient is in respiratory distress and cannot maintain an adequate airway on their own
79
endotracheal intubation can be left in for
14-21 days. after that, a tracheostomy is required
80
tracheotomy
is a surgical procedure in which an opening is made into the trachea
81
immediately after intubation the nurse should
check symmetry of chest expansion auscultate breath sounds anterior and lateral obtain chest x-ray and capnography
82
ARF is defined as a decrease in arterial oxygen tension (PaO2) to less than 60 mm Hg (hypoxemia) and an increase in arterial carbon dioxide tension (PaCO2) to >50 mm Hg (hypercapnia), with an arterial pH less than 7.35.
decreased PaO2 less than 60mmHg (hypoxemia) increased PaCO2 over 50mmHg (hypercapnia) decreased pH less than 7.35
83
5mm induration
positive for those at risk. people with HIV, those who have been around someone with HIV,
84
10 mm induration or greater
considered significant in people who have normal or mildly impaired immunity.
85
A significant (positive) reaction does not necessarily mean that active disease is present in the body. More than 90% of people who are tuberculin-significant reactors do not develop clinical TB
86
sputum specimen for TB
if positive for AFB, MAY indicate disease but does not confirm diagnosis
87
key characteristic of pleurisy
its relationship to respiratory movement. Taking a deep breath, coughing, or sneezing worsens the pain
