A.Recurrent attacks of severe upper abdominal and back pain accompanied by vomiting
Chronic pancreatitis has recurrent attacks of severe upper abdominal and back pain accompanied by vomiting. Acute pancreatitis presents with fever, jaundice, confusion, agitation, ecchymosis in the flank or umbilical area, and abdominal guarding.
refers to diseases that obstruct air flow and commonly includes chronic bronchitis and emphysema (airflow limitation)
Exacerbation and co-morbidity contributes to the clinical manifestations
contributes to the clinical manifestations
Presents with 3 cardinal signs and symptoms
Less common signs
- Chest tightness
COPD SIGNS AND SYMPTOMS
cigarette, air pollution, allergy, autoimmunity, infection, occupational exposure, aging etc.
Excessive mucous production resulting in chronic cough is characteristic of chronic bronchitis.
RISK FACTOR FOR COPD
Inflammatory changes leads to mucociliary dysfunction & bronchial constriction
Increase production of mucus with a chronic cough that persists for at least 3 months of the year for 2 consecutive years
With continued irritation epithelial cells die, destroying their Celia
Goblet cells hypertrophy creating more tenacious mucus
The inability to clear the airway of excess mucus causes susceptibility to infections
Repeated infections lead to airways showing scarring, stenosis and obstruction
- Because of the loss of alveolar walls and the capillaries surrounding them, there is increased pressure in the pulmonary circulation.
- This, along with thickening of the blood vessels, results in pulmonary hypertension.
- Which in turn leads to right side heart failure /cor pulmonale.
- Common characteristics
- Mucus hypersecretion
- Dysfunction of cilia
- Hyperinflation of lungs
- Gas exchange abnormalities
Productive cough, exertional dyspnea, and wheezing
Over time, hypoxemia (PaO2 <60 mm Hg or O2 saturation <88%) may develop with hypercapnia (PaCO2 >45 mm Hg) leading to respiratory acidosis.
Because of their reduced oxygen saturation they start to retain fluid.
polycythemia develops as a result of increased production of red blood cells as the body attempts to compensate for chronic hypoxemia.
the resp. acidosis , polycythemia and < O2 leads to the constant cyanosis and bloated appearance and that’s why chronic bronchitis is referred to as “blue bloaters”
CLINICAL MANIFESTATIONS COPD
Degenerative, nonreversible disease characterized by
–Destruction of the alveoli
–Enlargement of the distal airspaces
–Breakdown of alveolar walls leads to loss of alveolar recoil+ decrease ventilation
Breathing out is the main problem
Thin, emaciated body frame
Dyspnea on exertion, later at rest
Shortness of breath and “air hunger”
Chronic productive cough
Classic “barrel chest” indicating constant lung over inflation and overwork of chest muscles used for breathing (diaphragm).
Dilatation and destruction of lung tissue distal to terminal bronchioles.
It leads to air trapping and an increase in total lung capacity.
There is also a loss of alveolar tissue, reducing capacity for gas exchange.
Carbon dioxide clearance is not impaired to the same extent as chronic bronchitis, usually because patients increase their respiratory effort and ventilation, the pt. Is not usually cyanotic
Instead you will observe a pinkish skin color and that is why they are called “pink puffers”
CXR, CT scan
Pulmonary function tests
Pulmonary test to rule out TB or malignancy
Diagnostic Eval. Of COPD
Elevated Hct - to low oxygenation levels
Hypoxemia-low PO2 less than 80mmHg
Hypercapnia- high PCO2 -45 mmHg
The nurse reviews the arterial blood gases of a patient. Which result would indicate the patient has later stage COPD?
pH 7.32, PaCO2 58 mm Hg, PaO2 60 mm Hg, HCO3 30 mEq/LnpH 7.30, PaCO2 45 mm Hg, PaO2 55 mm Hg, HCO3 18 mEq/L
pH 7.40, PaCO2 40 mm Hg, PaO2 70 mm Hg, HCO3 25 mEq/L
pH 7.52, PaCO2 30 mm Hg, PaO2 80 mm Hg, HCO3 35 mEq/L
Rationale: In later stage COPD, the patient will have a low or low normal pH, a high normal or above normal PaCO2, and a high normal or above normal HCO3-. This indicates compensated respiratory acidosis, as the patient has chronically retained CO2 and the kidneys have conserved HCO3- to increase the pH to near or within the normal range.
This image shows multiple cystic areas caused by destruction of lung tissue typical of emphysema.
Lung Severe Emphysema:
The chest cavity is opened at autopsy to reveal numerous large bullae apparent on the surface of the lungs in a patient dying with emphysema.
Bullae are large dilated airspaces that bulge out from beneath the pleura.
Emphysema is characterized by a loss of lung parenchyma by destruction of alveoli so that there is permanent dilation of airspaces
nCan improve survival in patients with advanced COPD who have hypoxemia, (low blood oxygen levels)
nThis treatment can improve a patient's exercise tolerance and ability to perform on psychological tests which reflect different aspects of brain function and muscle coordination
HOME OXYGEN THERAPY COPD
Increasing the concentration of oxygen in blood also improves the function of the heart and prevents the development of Cor pulmonale.
Monitor amount of oxygen given. No more than 3L is recommended. Why?
Some patients cannot maintain this effort and their carbon dioxide levels rise. This stimulates respiratory drive for a time, but then they become desensitized to it and they depend on hypoxemia to drive ventilation.
Oxygen can also lessen sleeplessness, irritability, headaches, and the overproduction of red blood cells.
n Continuous oxygen therapy is recommended for patients with low oxygen levels at rest, during exercise, or while sleeping.
nReview Oxygen delivery system (NC, Mask etc..)
Suppressed respiratory drive and low O2
COMPLICATIONS OF OXYGEN THERAPY
Corticosteroids or Steroids
Cough suppressants (codeine, etc.)
Sleeping pills (barbiturates, etc.)
- The choice of bronchodilator depends on the patient’s response. However, when the patient has mild COPD or fewer symptoms, a short-acting bronchodilator is used as needed.
- Albuterol or ipratropium (Atrovent) may be used as single agents, but combining bronchodilators improves their effect and decreases the risk of adverse effects. These two agents (albuterol and ipratropium) can be nebulized together (DuoNeb) or delivered by one MDI (Combivent Respimat).
- In the moderate stages of COPD, a long-acting bronchodilator may be used in addition to a short-acting rescue bronchodilator, such as salmeterol (Serevent) or formoterol (Foradil).
Surgical removal of large air spaces called bullae that are filled with stagnant air
May be beneficial in selected patients
Recently, use of lasers to remove bullae has been suggested
nHas been successfully employed in some patients with end-stage COPD.
n In the hands of an experienced team, the 1-year survival in patients with transplanted lungs is over 70 percent.
Help to overcome the conditions which cause dyspnea, anxiety and allergic reactions
Airway clearance techniques
Improve capacity for physical exercise and activities of daily living
Frequent rest periods
Diet : Offer small frequent meals;
high calorie, high protein
2-3L fluid unless contraindicated IV/PO
n Intermittent mechanical ventilatory support relieves dyspnea and rests respiratory muscles in selected patients.
nPurse lip breathing techniques
Continuous positive airway pressure (CPAP) is used as an adjunct to weaning from mechanical ventilation to minimize dyspnea during exercise.
Relaxation techniques may also reduce the perception of ventilatory effort and dyspnea
Breathing exercises and breathing techniques, such as pursed lips breathing and relaxation
Place in high Fowler’s position or seated on the bedside with the arms folded on the over bed table to promote full lung expansion (Tripod)
Keeping air passages reasonably clear of secretions is difficult for patients with advanced COPD.
Re: Some commonly used methods for mobilizing and removing secretions are already discussed.
nAvoid smoking environment
nBreathing toxic fumes such as glue, paint etc.
nAerosol products other than meds
nGoing to places with polluted atmosphere
nAvoid people with infections etc..
C: IS FOR CONTROLLED ENVIROMENT
Highly communicable disease
Caused by mycobacterium tuberculosis
–Rod shaped, gram+, acid fast bacillus (AFB)
WHAT IS TB?
Spread by airborne droplet from an affected person during
Another person breathes in the bacteria & becomes infected
TRANSMISSION OF TB
The tuberculosis bacterium invades the alveoli and begins to multiply forming a tubercle lesion
The body’s defense mechanism encapsulate the tubercle leaving a scar.
May continue to grow to form granulomas or cheese like mass called caseation
This is what is seen on a CXR and is called the Ghon tubercle or primary lesion
Primary lesions form, they may become dormant, but can be reactivated and become a secondary infections when re-exposed to the bacterium
Dissected, preserved lung with tuberculosis TB
Close contact with infected person
Live in areas where TB in common
HIV infections, immune system diseases
Homeless, poor, crowded living conditions
Poor access to heath care
Illicit drug use
Health care professional
WHOS AT RISK TB
TB has an insidious onset and many pts are not aware of the symptoms until the disease is well advanced
Fever, night sweats, malaise
Anorexia and weight loss
Cough non productive at first, but later produces yellow mucoid sputum
Pleuritic chest pain and tightness
Dyspnea if severe lung involvement
CLINICAL MANIFESTATIONS OF TB
H&P especially for pts at risk
Tests: Sputum smear and C&S
–AFB x 3 samples are usually obtained for an acid-fast smear . (May aspirate gastric fluid if unable to obtain specimen)
–The sputum test confirms the diagnosis of TB because
–Determines the presence of Ghon tubercles or lesions on the lungs and the extent of the disease (cheesy caseations)
–Indicates presence and extent of disease process but cannot differentiate active from inactive form
WBC and ESR increased
A + reaction is noted if the induration is greater than 5mm
This means that the patient has had contact with tubercle bacillus.
It does not mean that active disease is present in the body . (antibodies are now present)
Check for vaccination with BCG
DIAGNOSTIC TESTS TB
¨Goal of treatment is to prevent transmission, control symptoms, and prevent progression of the disease
¨6-12 months, may be as long as 24 months
¨2-4 meds Given concurrently
¨Mycobacteria grow slowly, resistance is common
vImproper or noncompliant use of treatment programs may cause the development of mutations in the tubercle bacilli resulting in a multidrug resistant strain of TB (MDR-TB
(+) Mantoux test, (-) CXR, and at risk for the disease are treated prophylactically to prevent development of active TB
Isoniazid (INH) for 9-12 months
Medical management TB
Combination drug therapy is most effective
–It destroys the organism and minimize development of multiple drug resistant strain of the bacilli
–After TB meds have been given for 2-3 weeks, the risk of transmission is reduced greatly
Drug of choice
Take with meals if GI upset otherwise take one hr before or 2hr after meals. Absorption is decreased if given with food
Avoid antacids exp. Aluminum based – decrease absorption
– drug is usually given with Vitamin B6 (Pyridoxine) to prevent this side effect
Nausea, vomiting, diarrhea, stomach pain
Avoid foods with tyramine
– aged cheese, smoked fish, tuna, sauerkraut, avocado etc.
Combined with INH will make you sicker
Drugs for TB : INH Isoniazid
150-300mg , maximum dose 600mg /day
S/S: hepatotoxicity, hepatitis, blood dyscrasias

Check for vaccination with BCG vaccine (Bacille Calmette-Guerin Vaccine)
Review other nursing measures in the Hinkle chapter.
NURSING MANAMGEMENT TB
Rheumatoid arthritis (RA) is a chronic disease in which various joints in the body are inflamed, leading to swelling, pain, stiffness, and the possible loss of function.
Rheumatoid arthritis should not be confused with other forms of arthritis, such as osteoarthritis or arthritis associated with infections.
Rheumatoid arthritis is an autoimmune disease in which the body's immune system attacks joints and other tissues.
The pattern of joints affected is usually symmetrical, involves the hands and other joints, and is worse in the morning.
Rheumatoid arthritis is a systemic (body-wide) disease, involving other body organs, whereas osteoarthritis is limited to the joints. Both forms of arthritis can be crippling.
