Objectives Discuss the pathophysiology of pneumonia Describe signs and symptoms of pneumonia Discuss risk factors for pneumonia Discuss the prevalence of pneumonia in our society Discuss medical and nursing interventions for pneumonia from current research Describe a patient case scenario Discuss medical and nursing interventions, treatments and outcomes for a hospitalized patient with pneumonia

Pathophysiology Infection of the lower respiratory tract caused by bacteria, viruses, fungi, protozoa or parasites. The alveoli and interstitium of the lung are filled with inflammatory cells and fibrin (Loebinger, 2012) and (Huether & McCance, 2012)

Pneumonia Pathophysiology Video

Most Common Bacterial Microbes Responsible for Pneumonia Streptococcus pneumoniae (most common cause of CAP) Chlamydia pneumoniae Mycoplasma pneumoniae Haemophilus influenzae Legionella spp. Chlamydia psittaci Staphylococcus aureus Moraxella catarrhalis The causative microorganism influences how the individual presents clinically, how the pneumonia is treated and the prognosis (Loebinger & Wilson, 2008)

Routes of Entry Inhalation of airborne pathogens Microorganisms that have been released into the air when we cough, sneeze or talk Aspiration of gastric and nasopharyngeal flora Spread from other infected sites (Loebinger & Wilson, 2012)

Risk Factors for Pneumonia Age 65 and older Very young children whose immune systems havent fully developed Smoking Compromised immunity Underlying disease Alcoholism Altered consciousness Impaired swallowing Endotracheal intubation Malnutrition Immobilization Underlying cardiac or liver disease Residence in a nursing home Poverty Long term corticosteroid use Exposure to certain chemicals or pollutants (Huether, McCance, 2012)

Symptoms of Pneumonia Cough Vomiting Headache Dyspnea Thoracic/Pleuritic pain Abdominal pain Poor appetite Diarrhea Rhinorrhea Malaise/Lethargy Sputum production Sweating (Juven, Ruuskanen & Mertsola, 2003) (Loebinger & Watson 2012) (Thiem, Heppner & Pientka, 2011)

Signs of Pneumonia Fever > 37.5C Cough Rhinorrhea Vomiting Malaise/Lethargy Confusion Dyspnea Poor appetite Diarrhea Sputum production Dehydration Adventitious breath sounds (rhonchi, rales/crackles, wheezing or decreased sounds) Respirations > 30/min Consolidation on chest X-ray Sweating Low blood pressure (Juven, Ruuskanen & Mertsola, 2003) (Loebinger & Watson, 2012) (Thiem, Heppner & Pientka, 2011)

Prevalence of Pneumonia in the United States Bacterial pneumonia remains one of the leading causes of morbidity and mortality Estimated 450 million cases per year worldwide Estimated 4 million deaths per year worldwide 6 th leading cause of death worldwide CAP= 350,000-620,000 hospitalizations each year (Loebinger & Watson, 2012) & (Huether & McCance, 2012 )

Medical Interventions From current research Antibiotic therapy Chest x-ray and/or CT scan Bronchoscopy Thoracentesis Daily blood tests/labs to monitor status of illness Oxygen therapy Breathing treatments Prescribing medication based upon the patients signs/symptoms Continuous IV fluids http://health.nytimes.com/health/guides/disease/pneumonia/overview.html

Nursing Interventions From current research Incentive spirometry (5-10 breaths) every 2 hours Chest physiotherapy Rhythmic breathing and coughing every 4 hours Monitoring breathing pattern, rate, effort, use of accessory muscles Monitor O2 saturation and arterial blood gases Assessing for changes in mental status, skin color and cyanosis Administer antitussives, mucolytics and antibiotics as prescribed Provide oxygen therapy Reposition patient q2h and position them in fowlers or semi- fowlers position Provide oral care after expectoration and provide tissues/bag for disposal Suction secretions if cough is ineffective Increase fluid intake http://nanda-nursinginterventions.blogspot.com/2011/05/nursing-interventions-for-pneumonia.html

Diagnostic Tests/Labs Non-laboratory tests Chest x-ray Bronchoscopy Throracentesis Computed tomography scan (CT Scan) Laboratory tests Complete Blood Count (CBC) Arterial Blood Gas (ABG) Basic Metabolic Panel (BMP) Tests for suspected bacterial pneumonia Sputum culture & gram stain http://labtestsonline.org/understanding/conditions/pneumonia/start/3

Commonly Used Medications

Prevention of Pneumonia Smoking cessation Frequent hand-washing Coughing/sneezing into a tissue, elbow or sleeve Cleaning frequently touched surfaces Vaccination against Streptococcus. Pneumoniae Most common cause of community acquired pneumonia The vaccine doesnt completely prevent pneumonia but it reduces the severity Recommended for: Patients over 5 years with immunodeficiency and chronic diseases (Loebinger & Wilson, 2012) http://labtestsonline.org/understanding/conditions/pneu monia/start/4

Patient Scenario The patient is a 74 year old female who complains of severe chest pain, difficulty breathing and difficulty clearing secretions. She complains of pain in her right lower chest. When asked to describe the pain on a scale from 0-10 she reported the intensity as a 6/10. She describes the pain as throbbing, sharp and constant. Her pain and trouble breathing is worse when she lays flat. Her symptoms decrease when sitting up in a chair. The patient was admitted to the hospital on October 30, 2012 where she is underwent treatment for community acquired pneumonia caused by Streptococcus pneumoniae.

Patient Scenario (cont.) Subjective Findings (Symptoms) Difficulty breathing Dry mucous membranes Fatigue (trouble sleeping) Difficulty clearing secretions Objective Findings (Signs) Tachypneic (RR: 28) Adventitious breath sounds (crackles in lower lobes) Dry mucous membranes Dyspnea Pallor Trouble clearing secretions Temperature 100.6F

Adventitious Lung Sounds (Crackles)

Patient Medications Acetaminophen Mucinex ALPRAZolam HYDROcodone Amoxicillin

Nursing Diagnosis Ineffective airway clearance r/t retained secretions a.e.b adventitious breath sounds Ineffective breathing pattern r/t body position a.e.b orthopnea Chest pain secondary to pneumonia a.e.b patient stating pain as a 6/10

Medical Interventions What was done while the patient was in the hospital Physician ordered a sputum culture to determine the virus or bacteria causing the pneumonia (Streptococcus pneumoniae) Physician ordered a chest x-ray to determine the area where the consolidation is located Prescribed pain medication (HYDROcodone) Prescribed antibiotics (amoxicillin) Prescribed Mucinex & ALPRAZolam Ordered breathing treatments from respiratory therapy

Nursing Interventions What was done while the patient was in the hospital Monitor respiratory rate, pattern, depth and ease of respiration Supplemental Oxygen (O2 @ 2L) Incentive spirometer use every hour Turn, cough and deep breath exercises every hour Pursed lip breathing exercises Assisting the patient to the chair every 3 hours to sit up to loosen lung secretions Elevating the HOB to 45 degrees to allow the patient to sit up to loosen lung secretions Respiratory therapy to provide breathing treatments 2x a day Administer medications as prescribed Increase fluids to prevent dehydration

Outcomes The patient was able to clear lung secretions 2x during my shift The patient transferred herself with assistance to the chair 3x during my shift She tolerated the breathing treatments from respiratory therapy well and was cooperative with all interventions Her breathing pattern and respiratory rate did not change before my shift ended The patient was not discharged during my shift
