25
goals for acute tracheobronchitis

26
nursing interventions for acute tracheobronchitis
```

27
Pneumonia patho
Inflammation of the lung caused by various microorganisms
28
causes of Pneumonia
Bacteria, mycobacteria, fungi, viruses
29
statistics about pnemonia
1. Most common cause of death from infectious disease in the US
2. Viruses are most common cause in infants and children.
3. 8th leading cause of death in the US in 2012.
30
pnemonia patho
Inflammation in the alveoli producing exudate (sticky substance) that interferes with diffusion of O2 and CO2
WBCs fill the normally air-filled alveoli causing bronchospasms.
Poorly oxygenated blood eventually results in arterial hypoxemia.
31
Bronchospasm occurs when
the airways (bronchial tubes) go into spasm and contract. This makes it hard to breathe and causes wheezing
32
V./Q. refers to
the ratio between ventilation and perfusion in the lung, which is normally approximately 4 to 5
33
lobar pneumonia is defined
If a substantial portion of one or more lobes is involved, the disease is referred to as
34
classifications of pnemonia
Community-acquired pneumonia (CAP)
Health care-associated pneumonia (HCAP)
Hospital-acquired pneumonia (HAP)
Ventilator-associated Pneumonia (VAP)
35
Community-acquired pneumonia (CAP)
Occurring in the community or <48 hours after hospital admission.
36
Health care-associated pneumonia (HCAP)
```
Non-hospitalized patient with contact with one or more of:
hospitalization for >2 days,
nursing home,
antibiotic therapy,
hemodialysis,
wound care,
infected family member
```
37
Hospital-acquired pneumonia (HAP)
Occurring >48 hours after hospitalization
38
Ventilator-associated Pneumonia (VAP)
Occurring >48 hours after endotracheal intubation
39
An important distinction of HCAP
is that the causative pathogens are often MDROs
40
A multidrug resistant organism (MDRO)
is a germ that is resistant to many antibiotics
41
HCAP is often difficult to treat, thats why ____
initial antibiotic treatment must not be delayed
42
HAP is associated with a high mortality rate, in part because
of the severity of the organisms, the resistance to antibiotics, and the patient’s underlying disorder
43
preventative measure for: Patients who are immunosuppressed or neutropenic (low neutrophil count)
Initiate special precautions against infection
44
preventative measure for: Prolonged immobility and shallow breathing pattern
Reposition frequently and promote lung expansion exercises
45
preventative measure for: Depressed cough reflex (due to medications, a debilitated state, or weak respiratory muscles)
Reposition frequently to prevent aspiration
46
preventative measure for: placement of nasogastric, orogastric, or endotracheal tube
Minimize risk for aspiration by checking placement of tube
47
preventative measure for: Supine positioning in patients unable to protect their airway
Elevate head of bed at least 30 degrees
48

63
Pleurisy patient education
The nurse educates the pt to turn and splint frequently onto the affected side to splint the chest wall.
64
Pleural Effusion
Collection of fluid in pleural space.
Usually secondary to another disease process.
Thoracentesis may be performed
65
what is a sign of Pleural Effusion
Empyema: Accumulation of thick, purulent fluid in pleural space

87
Tuberculosis
An infectious disease that affects the lung parenchyma (functioning portion of the lung tissue)
88
the infectious agent of Tuberculosis
"M. tuberculosis" is the infectious agent
89
Tuberculosis infects
one third of the world’s population
90
Tuberculosis is associated
with poverty, malnutrition, substandard housing, and inadequate healthcare
91
Pathophysiology of TB
1. Bacteria are transmitted through the airway to the alveoli
2. Immune response occurs to lyse (destroy) the bacilli and normal tissue
3, Accumulation of exudate occurs in the alveoli which can cause pneumonia
92
TB's Initial infection usually occurs
2 to 10 weeks after exposure
93
TB Could be dormant. Becomes Active disease
due to Immunosuppressed patients or reinfections
94
TB spreads from person to person by
airborne transmission
95

```
100
TB assessments and diagnostics
1. Complete history (traveled to countries?)
2. Physical examination
3. Thorough respiratory assessment
4. Tuberculin skin test
5. Chest X-ray
101
Thorough respiratory assessment for TB includes:
assessing the lungs for consolidation by evaluating breath sounds (diminished, bronchial sounds; crackles), fremitus, and egophony.)
102
If the patient is infected with TB, the chest x-ray usually
reveals lesions in the upper lobes.
103
The Mantoux method is used to determine
whether a person has been infected with the TB bacillus
104
what are the steps for injecting TB skin test?
1. purified protein derivative (PPD), is injected into the intradermal layer of the inner aspect of the forearm, approximately 4 inches below the elbow.
2. The needle, with the bevel facing up, is inserted beneath the skin.
3. Then, 0.1 mL of PPD is injected,
105
A significant (positive) PPD reaction does
not necessarily mean that active disease is present in the body.
106
Mantoux test readings
(Negative) = redness only
(Positive) = Wheel greater than 6-10 mm
(positive) = “immunosuppressed” wheel is 5+ mm diameter
107
A significant (positive) reaction indicates
past exposure to M. tuberculosis or vaccination with bacille Calmette-Guérin (BCG) vaccine
108
QuantiFERON-TB Gold In-Tube and T-SPOT
TB blood tests.
Preferred test for patients who have received the vaccine.
Available within 24 to 36 hours.
A positive test indicates a possible infection.
Sputum culture is completed to confirm positive diagnosis.
109
TB Can cause atypical manifestations in geriatrics such as
Unusual behavior
| Altered mental status
110
in geriatrics, TB skin test reaction is
delayed by 1 week, and a second TB skin test should be performed 1-2 weeks after
111
Geriatrics are at a higher risk when
living at a long term care facility
112
TB medical management
Anti-TB agents for 6 to 12 months to eradicate organisms and prevent relapse
113
Four anti-TB medications given at beginning of treatment (given as a cocktail)
Isoniazid (INH)
Rifampin (Rifadin)
Pyrazinamide (PZA)
Ethambutol (Myambutol)
114
those 35 years or younger who have PPD test results with 10 mm of induration or more and who are foreign-born from countries with a high prevalence of TB are suggested to take
Prophylactic isoniazid (INH) treatment involves taking daily doses for 6 to 12 months.
115
pulmonary TB medications regimen
Take the 4 Medication cocktail once a day for 2 months and are oral medications then continues a 4-7 months PO depending on culture result
116
Common side effects of TB medications:
Hepatitis
Neuritis
(nausea + vomiting)
117
Nursing Management for TB patients
Promoting airway clearance
Advocating adherence to treatment regiment
Promoting activity and nutrition
Preventing transmission
118
Promoting Airway Clearance for TB
Increase fluid intake to promote systemic hydration
Positioning for breathing comfort
119
lower and middle lobe bronchi drain more effectively when
the head is down
120
the upper lobe bronchi drain more effectively when
the head is up.
121
Rifampin lowers the effectiveness of these medications.
beta blockers,
anticoagulants
or contraceptives
122
rifampin, it can cause an
orange tint to their urine.
123
TB is a communicable disease and that taking medications
is the most effective means of preventing transmission
124
The nurse educates the patient to take the medication either
on an empty stomach or at least 1 hour before meals,
125
Patients taking isoniazid should avoid foods that contain
tyramine and histamine (tuna, aged cheese, red wine, soy sauce, yeast extracts), to avoid headaches and hypotension
126
Patients should also avoid alcohol because
of the high potential for hepatoxic effects.
127
Promoting Activity and Adequate Nutrition for TB
Goal: To increase activity tolerance and muscle strength
Willingness to eat may be altered
Identify facilities that provide meals to patients with limited resources
Small frequent meal planning
Liquid nutritional supplements
128
Preventing Transmission patient teachings include:
Covering mouth and nose while sneezing and coughing.
Hand hygiene.
Proper disposal of tissues.
Watch for transmission signs to other organs in the body.
129
Watch for transmission signs to other organs in the body by:
Frequent vital signs
Spikes in temperature
Changes in renal or cognitive function
130
miliary TB
Spread of TB infection to nonpulmonary sites of the body
