    COPD Overview

    • Chronic Obstructive Pulmonary Disease (COPD) affects 15 million individuals in the U.S. and 900,000 in Canada.
    • Fourth leading cause of morbidity and mortality in the U.S.

    Definition and Pathophysiology

    • COPD is a collection of lower airway disorders that interfere with airflow and gas exchange.
    • Key components of COPD include emphysema and chronic bronchitis.

    Emphysema

    • Destructive condition affecting lung elastic tissue, leading to reduced recoil and hyperinflation.
    • Damaged alveoli cause air trapping and decreased gas exchange, resulting in CO2 retention and respiratory acidosis.

    Chronic Bronchitis

    • Inflammation of the bronchi and bronchioles due to irritant exposure, primarily cigarette smoke.
    • Thickening of bronchial walls and increased mucus production result in obstructed airflow and chronic infection.

    Risk Factors

    • Major risk factor: Cigarette smoking.
    • Other risks include alpha1-antitrypsin deficiency and a history of asthma.

    Complications of COPD

    • Hypoxemia can lead to respiratory acidosis, respiratory infections, cardiac failure (cor pulmonale), dysrhythmias, and respiratory failure.

    Assessment and Recognition of Cues

    • Physical assessment includes respiratory and cardiac changes, as well as psychosocial factors.
    • Laboratory assessments involve monitoring ABG’s and pulse oximetry, aiming for O2 saturation of 88-92%.

    COPD Management Strategies

    • Emphasize weight management and dyspnea management through small, frequent meals and energy conservation techniques.
    • Encourage anxiety management techniques and regular physical activity.

    Health Promotion

    • Smoking cessation is crucial for disease management and secondary prevention.
    • Use of the I-PREPARE model for health promotion.

    Care Coordination

    • Home care management should include oxygen therapy, self-management education, and access to healthcare resources.
    • Focus on maintaining gas exchange, effective breathing patterns, and preventing serious respiratory infections.

    Goals of Evaluation

    • Maintain gas exchange at chronic baseline values; achieve a breathing pattern that lowers work of breathing.
    • Control body weight within 10% of ideal weight and reduce anxiety levels.

    NCLEX Style Questions

    • Example question regarding dyspnea indicates that nighttime breathing difficulties may suggest worsening condition.
    • Proper assessment of chest tubes involves ensuring no loose bandages post-surgery.
    • Emergency response for asthma involves prioritizing rescue drug administration when peak flow readings are critical.

    Concepts

    • Priority Concept: Gas Exchange
    • Interrelated Concepts: Perfusion, Inflammation, Cellular Regulation

    Respiratory System Overview

    • Upper Airway Components: Nares (nostrils), pharynx, larynx (houses vocal cords), ciliated mucous membranes, tonsils
    • Lower Airway Components: Trachea, bronchi, bronchioles, alveoli (site of gas exchange)

    Differences in Pediatric and Adult Respiratory Systems

    • Infants have insufficient surfactant and smaller, undeveloped airways
    • Infants primarily breathe through their nose and have less-developed intercostal muscles
    • Brief apnea episodes are common in newborns
    • Higher respiratory rates due to increased metabolic needs
    • Eustachian tubes are more horizontal, leading to greater susceptibility to ear infections
    • Tonsillar tissue is more pronounced, and larynx flexibility makes it prone to spasms
    • Infants predominantly use abdominal breathing

    Asthma: Incidence and Prevalence

    • Asthma can develop at any age but peaks between 10-17 years
    • It is the leading cause of acute and chronic illness in children
    • About 8.3% of children in the U.S. have asthma, with prevalence higher in African Americans and urban areas

    Asthma Pathophysiology

    • Chronic and intermittently occurring disease influenced by genetic and environmental factors
    • Results in airway inflammation and sensitivity
    • Characterized by bronchoconstriction, mucus production, and airway tissue edema

    Asthma Reactions

    • Immediate Reaction: Triggered by allergens activating IgE receptors on mast cells; leads to bronchoconstriction
    • Late Reaction: Involves eosinophils and neutrophils causing prolonged inflammation, edema, and mucus plugging

    Assessment of Asthma History

    • Considerations include premature birth, family history, previous wheezing, exercise-induced cough, and allergies
    • Hospitalization history and frequency of asthma episodes should be noted

    Risk Factors for Asthma

    • Strong family history of asthma
    • Severe lower respiratory infections in the past
    • Presence of allergies or atopy (allergic triad)
    • More common in boys and those born prematurely

    Asthma Triggers

    • Include cold air, smoke, allergens, respiratory infections, stress, exercise, and certain medications

    Assessment: Signs and Symptoms

    • Monitor vital signs and watch for color changes, lung sounds (wheezing, stridor), and use of accessory muscles
    • Signs of distress may include restlessness, anxiety, and difficulty talking or moving

    Asthma Diagnostics

    • Use of pulse oximetry, end-tidal CO2 monitoring, arterial blood gases (ABGs)
    • Peak flow meters used for daily monitoring; abnormal pulmonary function tests are diagnostic
    • Testing for allergic rhinitis or sinusitis is common among asthmatics

    Asthma Classification

    • Categories: Intermittent, Mild Persistent, Moderate Persistent, Severe Persistent

    Therapeutic Management of Asthma

    • Goals include improving airflow and gas exchange through assessment, collaboration, avoidance of triggers, and medication management
    • Education for patients and families is essential, including adherence to asthma action plans

    Asthma Medications

    • Rescue Drugs: Short-acting bronchodilators (e.g., Albuterol, Levalbuterol) used for acute attacks
    • Control Therapy Drugs: Long-term management includes inhaled corticosteroids, long-acting beta agonists, and leukotriene inhibitors

    Signs of Emergency Treatment Needs

    • Urgent symptoms: worsening wheeze, ineffective bronchodilator response, difficulty breathing, fatigue
    • Severe signs: gray or blue lips, weak cry, trouble walking or talking

    Status Asthmaticus

    • Life-threatening acute episode not responsive to typical treatments
    • Can lead to pneumothorax or cardiac arrest; requires aggressive treatment including IV fluids, bronchodilators, steroids, and potential intubation

    Environmental Modifications for Asthma Management

    • Recommendations include frequent washing of bedding, avoiding certain materials, and using air filters and dehumidifiers to reduce allergens in the home

    General Overview of Anemia

    • Anemia is characterized by a reduction in the number of red blood cells (RBCs), hemoglobin levels, and hematocrit percentages.
    • It serves as a clinical indicator rather than a specific disease, implying various underlying causes.

    Causes of Decreased RBCs

    • Increased Destruction of RBCs

      • Examples include autoimmune hemolytic anemia and G6PD deficiency anemia.

    • Decreased Production of RBCs

      • Often linked to iron deficiency, resulting from insufficient dietary iron.

    • Chronic Blood Loss

      • Potential sources include:
        • Acute trauma leading to blood loss.
        • Gastritis, which can contribute to chronic blood loss.
        • Menstrual periods, which can result in significant blood loss.
        • Hemorrhoids, another source of blood loss.

    Nursing Interventions

    • Nursing interventions remain consistent regardless of the anemia's underlying cause.

    Hemoglobin and Hematocrit in CBC

    • Hemoglobin (Hgb)

      • An iron-rich protein within RBCs, vital for oxygen transport.
      • Measured in grams per deciliter (g/dL).
      • Level varies with age and sex.

    • Hematocrit (Hct)

      • Represents the percentage of packed RBCs in a given volume of blood.
      • Expressed as a percentage (%) and varies with age and sex.

    Respiratory Drugs Overview

    • Beta2-adrenergic agonists are used for bronchodilation and have inhaled, systemic, and long-acting forms.
    • Common short-acting examples include Albuterol, Levalbuterol, and Terbutaline; long-acting examples are Formoterol and Salmeterol.
    • Beta-adrenergic blockers can diminish the bronchodilating effects of agonists.

    Anticholinergic Drugs

    • Anticholinergics, like Ipratropium bromide, provide bronchodilation and relieve COPD and asthma symptoms.
    • Inhalation forms work locally, onset is 15-20 minutes, with effects lasting 3-5 hours.

    Corticosteroids

    • Corticosteroids are effective for preventing acute asthma attacks.
    • Inhaled forms (e.g., Beclomethasone) and systemic forms (e.g., Prednisone, Hydrocortisone) may be used.
    • Special considerations for corticosteroid use include monitoring growth in children, osteoporosis in the elderly, and blood glucose levels in diabetics.

    Leukotriene Modifiers

    • Leukotriene modifiers (e.g., Montelukast, Zafirlukast) inhibit the effects of leukotrienes, reducing airway constriction and inflammation.
    • They are often prescribed for mild to moderate asthma.

    Mast Cell Stabilizers

    • Mast cell stabilizers, such as Cromolyn sodium, prevent the release of inflammatory mediators and are suitable for long-term asthma control.
    • They are particularly effective in children and for exercise-induced asthma.

    Methylxanthines

    • Theophylline, aminophylline, and caffeine fall under methylxanthines, which promote bronchodilation and reduce airway reactivity.
    • Therapeutic levels for Theophylline are between 10-20 mcg/mL; toxicity risk increases with high-fat diets.

    Expectorants

    • Guaifenesin is a commonly used expectorant that thins mucus, easing its clearance from airways.
    • It alleviates symptoms associated with bronchitis, colds, and other respiratory conditions.

    Antitussives

    • Antitussives like Dextromethorphan and Codeine help manage non-productive coughs but carry risks of CNS depression, especially with certain drug combinations.
    • Not recommended for chronic conditions such as asthma or COPD.

    Mucolytics

    • Mucolytics, including Acetylcysteine, thin thick secretions and are used in conditions like bronchitis and cystic fibrosis.
    • Acetylcysteine is also an antidote for acetaminophen overdose.

    Decongestants

    • Decongestants cause vasoconstriction, decreasing inflammation and capillary permeability.
    • Topical decongestants typically have fewer side effects, while systemic options may lead to jitteriness and sleep disturbances.
    • Pseudoephedrine is sold behind the counter due to its potential misuse in methamphetamine production.

    Colony Stimulating Factors

    • Epogen, a colony stimulating factor, increases red blood cell production and is utilized to treat anemia.
