Objective: To discuss/describe topics related to the nursing process. Importance: Nurses work in various health care settings so it is important to gain an understanding of this subject as it will apply to your clinical practice. Fit: While caring for a patient with a respiratory disorder, the licensed vocational nurse must apply knowledge of pulmonary anatomy and physiology, as well as principles to support the emotional anxiety that accompanies respiratory distress. Chronic obstructive pulmonary disease is a progressive and irreversible condition that is characterized by decreased inspiratory and expiratory capacity of the lungs, which includes emphysema, chronic bronchitis and asthma. Patients with chronic respiratory disease are a challenge because the goal is symptomatic control rather than prevention. Approach: You will be presented the subject in lecture format and will be tested using a written exam at a later date. Control Statement: If you have any questions during the lesson please feel free to ask. BODY 1. Teaching Point: Describe the etiology/pathophysiology, clinical manifestations, assessment, diagnosis, medical management and nursing interventions of emphysema. Minutes Allocated Time: Introduction: Learner Participation: Knowledge Lesson Please follow along with your hand outs and take notes. Skill Lesson Powerpoint presentation with associated handouts. Learning Support: a. Etiology/Pathophysiology (1) Symptoms develop when a patient is in their 40s progressing to disability in the 50s and 60s (2) Characterized by changes in alveolar walls and capillaries (See p. 395 Figure 9-14, C) (3) Pathophysiology (a) Lung elastin, the component of lung connective tissue that provides the elasticity, is destroyed by an enzyme (b) Results in decreased pulmonary surface area available for gas exchange 2 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease (c) Bronchi, bronchioles and alveoli become inflamed due to chronic irritation causing bronchiolar narrowing (d) Results in trapping of air in the alveoli during expiration, causing alveolar distention (e) The alveoli rupture and scar, losing their elasticity (f) Alveoli walls break down and form enlarged air sacs (called blebs) (g) Capillary beds are replaced with fibrous scarring (h) Gas exchange is compromised resulting in hypoxia and hpercarbia (increased CO2) (4) Causes (a) Primarily cigarette smoking - usually about 30 to 35 years between onset of smoking and development of symptoms (b) Air pollution (c) Age (5) May lead to cor pulmonale (a) Right sided heart failure due to fibrotic changes in the lung and resultant pulmonary hypertension (b) Results in lower extremity, sacral and perineal edema, distended neck veins and ascites b. Clinical Manifestation (1) Exertional dyspnea is the primary symptom of emphysema. . (2) Sputum - minimal at the onset of the disease, but copious in later stages (3) Use of accessory muscles. (4) Spontaneous pursed-lip breathing (5) Development of barrel chest –an increase in anteroposterior diameter caused by over inflation (See figure 9-16, page 396 for illustration) (6) Wheezing (due to air movement through narrowed bronchioles) (7) Chronic weight loss with emaciation c. Assessment (1) Subjective 3 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease (a) History of onset of symptoms to include intensity of dyspnea, cough and sputum production (b) Identification of history of smoking or exposure to inhalational irritants (c) Note family history of respiratory disease (2) Objective (a) Tachycardia (b) Tachypnea (c) Peripheral cyanosis (d) Clubbing of fingers (e) Lung examination will include auscultation, listening for expiratory wheezing, percussion will reveal tympanal d. Diagnostic test the goal of the diagnostic examination is to determine the severity of the disease and its impact on the patient’s quality of life (1) Pulmonary function test (PFT) (a) Performed to measure 1) Total lung capacity- decreased 2) Residual volume (RV)- increased. (volume remaining in lungs at end expiration) 3) Compliance- increased (distensibility of lung) 4) Airway resistance- increased (due to narrowing of bronchioles) (2) Arterial blood gas (a) Decreased PaO2 (b) Increased PaCO2 (c) Normal pH, as a result of compensation (will reveal an elevated HCO3) (3) Chest x-ray (a) Reveals hyperinflation of lungs, widened intercostal spaces, and flattened diaphragm (b) Increased anterior-posterior (AP) diameter (barrel chest) (4) Labs 4 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease (a) Alpha1-antitrypsin assay to determine enzyme deficiency (familial deficiency which causes emphysema, even in nonsmokers) (b) Complete blood count 1) Reveals elevated erythrocytes, hemoglobin, and hematocrit 2) Indicates secondary polycythemia (a compensatory mechanism due to chronic hypoxia) e. Medical Management-the plan will include long-term management with home oxygen therapy and chest physiotherapy. In acute exacerbations, mechanical ventilation may be required (1) Medications (a) Bronchodilators 1) Enlarges bronchioles for greater oxygenation and ease of secretion clearance 2) Include terbutaline, isoproterenol, and albuterol inhalers 3) Patients may also receive PO theophylline (2) Antibiotics are frequently ordered to reduce the risk of pulmonary infection during exacerbations (3) Corticosteroids (a) Usually prescribed only during acute exacerbation because of the long-term side affects associated with systemic steroids (b) Used to decrease pulmonary inflammation and obstruction (4) Diuretics may be used for fluid removal (5) Oxygen therapy to increase oxygenation (6) Anti-anxiety agents (a) Patients with chronic respiratory disease can experience considerable anxiety, restlessness and irritability during exacerbations (b) Patients must be carefully monitored to evaluate for respiratory depression with these agents f. Nursing interventions (1) Directed at attempting to decrease patient’s anxiety and promote optimal air exchange (2) Oxygenation 5 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease (a) Elevate the head of the bed (b) Low flow oxygen 1-2 liters by nasal cannula - Important for the COPD patient, as respiratory drive can be depressed with high flow oxygen (normal drive to breath is CO2 levels; this changes with COPD when the respiratory drive is O2 levels) NURSING DIAGNOSIS Airway clearance, ineffective, related to narrowed bronchioles OUTCOME Patient will maintain patent airway Activity intolerance, related to imbalance between oxygen demand, secondary to inefficient work of breathing Patient will perform ADLs NURSING INTERVENTIONS 1) Assist with chest physiotherapy and postural drainage 2) Encourage fluids 2-3 L/day to liquefy secretions 3) Assist with respiratory treatments 4) Auscultate lungs frequently and notify physician of changes 5) Administer medications as ordered 1) Organize care so patient can have periods of uninterrupted rest 2) Advise patient to rest 30 minutes before meals 3) Assist patient with ADLs and exercises to increase stamina 4) Asses patient’s respiratory response to activity (3) Patient teaching will focus on optimizing nutrition and smoking cessation (a) Nutrition 1) Patient with emphysema has an increased protein and caloric requirement 2) Adequate protein and calories should be divided in five or six small meals per day 3) Instruct patient to drink fluids between meals, rather than with meals to reduce gastric distention on the diaphragm (b) Smoking cessation 1) Probably the most significant factor in slowing disease progression 2) Nicotine replacement helpful in minimizing nicotine craving 3) Encourage participation in support groups for behavior modification (c) Infection control 6 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease 1) Patient should receive flu vaccine each year and pneumovax every 5 years 2) Teach patient to avoid contact with those with an active respiratory infection 3) Teach/assess understanding of reasons to contact physician (d) Relaxation techniques- critical for the patient and family members to prevent complications of the disease process g.

Teaching Point: Describe the etiology/pathophysiology, clinical manifestations, assessment, diagnosis, medical management and nursing interventions of a patient with asthma. Minutes Allocated Time: Introduction: Learner Participation: Knowledge Lesson Please follow along with your hand outs and take notes. Skill Lesson Powerpoint presentation with associated handouts. Learning Support: a. Etiology/pathophysiology (1) Episodic increased tracheal/bronchial responsiveness to various stimuli 10 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease (2) Results in widespread narrowing of the airways which resolves spontaneously or in response to treatment (3) Classified as intrinsic or extrinsic (4) Results from an altered immune response or increased airway resistance and altered air exchange (5) Acute attacks are caused by the antigen-antibody reaction in which histamine (causes inflammation) is released (See figure 9-14, B, page 395 for an illustration) (6) There are three primary mechanism involved in producing allergy symptoms (a) Recurrent, reversible obstruction of the airway in the bronchioles and the terminal airway secondary to bronchospasm- the muscles of the airways constrict and narrow the air passages (b) Increased capillary permeability results in edema of mucous membranes- produces increased mucous production and narrowing of the airways (c) Acute inflammatory response in the mast cells of the lungs initiated by an asthma trigger- mast cells release histamine and other inflammatory producing substances that cause circulating inflammatory cells to migrate to the lungs b. Clinical manifestations (1) Mild asthma is manifested by dyspnea on exertion and wheezing. Symptoms can be easily controlled with medications (2) An acute asthma attack is most likely to occur at night and includes tachypnea, tachycardia, diaphoresis, expiratory wheezing, accessory muscle use, and nasal flaring (a) The musical wheezes often audible without a stethoscope are caused by air forcing its way out of narrowed airways (b) The patient experiences anxiety (3) Status asthmaticus (a) Severe, unrelenting form of asthma in which airway obstruction is unresponsive to drug therapy (b) Symptoms of an acute attack are present and the trapped air and increased work of breathing leads to exhaustion and respiratory failure c. Assessment (1) Subjective (a) Gather information related to quality of life, medications, asthma triggers and anxiety (2) Objective data 11 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease (a) Identify signs and symptoms suggesting severity of respiratory distress and impending respiratory failure 1) Presence of cyanosis 2) Amount of respiratory effort 3) Frequent vital signs 4) Auscultate for wheezing and decreased air movement 5) Check for patient assuming the tripod or hunched position in an effort to move more air d. Diagnostic tests (1) ABG- reveals hypoxia and hypercarbia (2) PFTs- used to test airway reversibility during and after an attack (reveals volumes consistent with air trapping) (a) Not particularly helpful during an acute asthma attack, as the patient cannot complete the test (b) Ask patient to perform peak flow (peak expiratory flow rate) (3) Chest x-ray reveals airway trapping and hyperinflation of the airways (4) Sputum culture to rule out secondary infection (5) CBC will reveal increased eosinophil count in the differential, which indicates allergic response (6) Theophylline level must be drawn on patient's taking this medication to ensure drug level is therapeutic e. Medical management- placed in two categories maintenance and rescue (acute) therapy (1) Maintenance therapy- used to prevent or minimize symptoms. Medications are taken long-term and on a daily basis (a) Bronchodilators- Salmeterol (Serevent)- long acting beta 2 agonist used for prophylaxis and not rescue. (b) Inhaled corticosteroids- Fluticasone (flovent)- decrease the inflammatory process in the airways. (c) Leukotriene inhibitors 1) New medications used to treat chronic asthma ranging from mild to more severe symptoms by antagonizing leukotrienes or inhibiting the synthesis of leukotrienes 2) Control both symptoms of asthma: bronchoconstriction and inflammation 12 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease a) Leukotriene receptor antagonists-zafirlukast (Accolate)and montelukast (Singulair) b) Leukotriene synthesis inhibitors zileuton (Zyflo) 3) Not to be used as only therapy for patients with persistent asthma 4) Not indicated for use in acute asthma attacks (2) Acute or rescue therapy works immediately to relieve symptoms of an acute attack. (a) Bronchodilators- short acting beta 2-agonist- albuterol which work quickly to relax airway muscles (b) Corticosteroids 1) A recent study shows inhaled corticosteroids (Flovent) given with inhaled beta2s may work faster than IV steroids 2) Intravenous methylprednisolone (Solu-medrol) may be used in an acute attack to decrease inflammation (c) Epinephrine 1) Used as a bronchodilator when beta2 agonists have not worked 2) May be administered SQ or IM (d) IV Aminophylline should only be considered in emergencies when all other medications have not relieved symptoms (3) Oxygen should be started immediately in an acute attack and should be monitored with pulse oximetry or serial ABG’s (4) A peak flow meter is a helpful tool to assist patient in monitor severity of symptoms (a) The peak flow meter measures peak expiratory flow rate (PEFR) a good indicator of lung function (b) Peak flow can help detect early signs of asthma attacks before they occur (c) Normal peak flow is between 80%-100% of expected expiratory function and is based on patient’s weight, age, and sex (d) Severe, persistent asthma is less the 60% (e) Severe life-threatening asthma is less than 50% 13 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease (4) Identification of triggers and education to prevent exposure to these triggers, or medical management of the response f. Nursing interventions nursing diagnosis most pertinent to asthma are: NURSING DIAGNOSIS Breathing pattern, ineffective, related to narrow airway OUTCOME Patient will maintain effective breathing pattern Health maintenance, ineffective, related to possible allergens in the home Patient will minimize allergen exposure in environment NURSING INTERVENTIONS 1) Assess ventilation and respiratory effort 2) Monitor closely for signs/symptoms of increasing dyspnea 3) Maintain position to facilitate optimal ventilation 4) Administer prescribed medications and monitor effects 5) Assist with respiratory treatments 6) Provide care in calm manner 7) Attempt to minimize exposure to triggers 8) Maintain adequate hydration 1) Assist patient and family identify allergens and asthma triggers 2) Facilitate allergy testing if necessary 3) Teach/assess understanding of the importance of allergy avoidance 4) Teach/assess proper use of medications ie Hold your breath for several seconds then exhale slowly after inhaling the medication 5) Teach/assess understanding of use of peak flow meter and goals for individual patient 6) Teach/assess understanding of reasons to call physician g. Prognosis (1) Death rate for asthma has increased by 50% over the past 10 years- disheartening as this disease can be controlled with medications and trigger avoidance (2) Status asthmaticus is fatal if not reversed 14 AFAMS Master Lesson Plan (MLP) Nursing Program Chronic Obstructive Pulmonary Disease Knowledge Lesson: Question: Answer: Check on Learning In a knowledge lesson, pose questions to the class.
