Pneumonia is an inflammation of the lungs that can be caused by bacteria, viruses, or fungi. It affects millions of people annually and can sometimes be fatal. The document discusses the epidemiology, classification, risk factors, pathophysiology, signs and symptoms, diagnosis, treatment, complications, and nursing care plan for pneumonia patients. Key points include the different types of pneumonia based on location (community-acquired vs. hospital-acquired), causative agents, and patient risk factors. Proper diagnosis involves tests of sputum or other samples, along with chest imaging. Treatment focuses on antibiotics, respiratory support, fluids, rest, and patient education.
5. Pneumonia:
•Definition
-Inflammation of lung parenchyma
-Caused either by bacteria, fungal, viral, mycobacteria
Primary pneumonia is caused by the client’s inhalation or
aspiration of a pathogen
Secondary pneumonia results from lung damage: spread of
an infectious agents from another site in the body, chemical
irritants (including gastric reflux and aspiration, smoke
inhalation)
Pneumonitis general term denoting inflammatory process
in the lung tissue predispose patient to microbial
invasion. 5
6. 2. Epidemiology
- 40 adults/1000/year
- Up to 10% acute adult admissions
- 8th leading cause of death in USA
- estimated 6 million cases are reported annually;
-hospital discharges attributed to pneumonia in 2009
-HAP accounts for 15% of hospital-acquired infections and
leading cause among those pts with HAP
-Pneumonia and influenza account for nearly 60,000 deaths
annually.

7. 3. Classification/Types of Pneumonia
i) 4 major classifications/types
•Community-acquired pneumonia (CAP)
•Hospital acquired Pneumonia (HAP)
•Pneumonia in the immune-compromised host
•Aspiration pneumonia
** Nosocomial pneumonias hospital acquired, ventilator
associated and health care-associated pneumonias (old term)
7
8. Definition of different types of pneumonias
•Community-acquired pneumonia (CAP): Pneumonia
occurring within 48 hours of hospital admission
streptococcus pneumoniae, H. influenza, Legionella,
and Pseudomonas aeruginosa.
•Health care–associated pneumonia (HCAP): Pneumonia
occurring in a non-hospitalized patient with extensive health
care contact with one or more of the following:
- Hospitalization for ≥2 days in an acute care facility within 90
days of infection
-Residence in a nursing care institution
-Antibiotic therapy or wound care within 30 days
- Hemodialysis treatment at a hospital or clinic
- Family member with infection due to multidrug-resistant
bacteria 8
9. •Hospital-acquired pneumonia (HAP): Pneumonia occurring
≥48 hours after hospital admission
Causative agent(s): Enterobacter species, E. coli, influenza,
Klebsiella species, Proteus, S. aureus, S. pneumonie
• Ventilator-associated pneumonia (VAP): A type of HAP that
develops ≥48 hours after endotracheal tube intubation
S. aureus
•Aspiration pneumonia: pulmonary injury resulting from entry
of endogenous or exogenous substances into the lower
airway.
- vomiting and aspiration of gastric or oropharyngeal contents
into the trachea and lungs
S. pneumonia, H.influenza, and S. aureus. 9
10. •Pneumonia in the Immunocompromised Host
includes Pneumocystis pneumonia/ Pneumocystis
jirovecii, fungal pneumonias and Mycobacterium
tuberculosis.
10
11. •ii) by causative agent
-Viral: Common causative organisms include respiratory
syncytial virus (RSV), influenza, and human parainfluenza
viruses
- Bacteria
Divided into typical and atypical types
Typical bacteria: Gram-positive Streptococcus pneumoniae,
Haemophilus, and Staphylococcus most common bacterial
causes
•Atypical: Mycoplasma pneumonie, Legionella pneumophila,
Chlamydia pneumonie, Mycobacterium tuberculosis,
Coxiella burnetii,
- Fungal: Histoplasma capsulatum, Coccidioides immitis,
Pneumocystis jirovecii (formerly carinii)
11
13. •iii) by site/anatomically
-Lobar: involving single lobe
- Broncho pneumonia: smaller lung areas in several lobes
-interstitial: tissues surrounding the alveoli and bronchi
13
14. 4. Risk factors
•Critical illness, ICU, Surgery
•Immunosuppression HIV, Chemotherapy, neutropenia
•Comorbidities e.g. heart or lung disease, DM, renal
diseases
•Malnutrition
•Smoking
•Age <16 or >65 years
•Recent antibiotic therapy
•Endotracheal intubation with mechanical ventilation
•Prolonged immobility
•Hospital procedures e.g. NGT insertion
14
15. 5. Pathophysiology
•Pneumonia arises from normal flora present in patients
whose low/compromised/altered immunity or from
aspiration of flora
•An inflammatory reaction in the alveoli
exudates that interfere with the diffusion of oxygen and
carbon dioxide
•White blood cells also migrate into the alveoli and fill the
normally air-filled spaces congestion and edema.
•Due to secretions and mucosal edema partial occlusion
of the brochi and alveoli inadequate ventilation
•Hypoventilation may follow causing ventilation-
perfusion mismatch poorly oxygenation of blood
hypoxemia
15
19. 7. Assessment and Diagnosis making
1. Assessment
- History taking and physical examination
Cough: productive/non productive, duration
Chest pain: nature, duration
Sputum: amount, colour
Shortness of breath and its extent
Vital signs: fever, respiratory and pulse rates
Auscultation breathing sounds, percussion abnormalities
2. Diagnosis:
-Sputum studies (Induce sputum if dry cough): MCS, AAFBs
- Chest X-ray (consolidation)
- Pleural fluid aspirate MCS
- FBC WCC/ESR
- Pleural biopsy 19
20. 8. Management of Pneumonia
Antimicrobial Uncomplicated pneumonia
•Amoxycillin 500mg TID po
•Ampicillin 500mg QID po
•Benzyl penicillin 1.2gm QID iv
•Erythromycin 500mg QID po
•Cefuroxime 750mg TID iv
•Cefotaxime 1gm BID
•Immunocompromised pt: Trimtoprim/Sulamethazole
(Cotrimoxazole)
•Fungal pneumonia: Voriconazole/Amphotericin B
•Aspiration pneumonia: Clindamycin with or without
Fluroquinolone
20
21. •Others:
•Immunocompromised pt: Trimtoprim/Sulamethazole
(Cotrimoxazole)
•Fungal pneumonia: Voriconazole/Amphotericin B
•Aspiration pneumonia: Clindamycin with or without
Fluroquinolone
•Tuberclosis: put on Antituberculosis drugs
•MRSA- Vancomycin/Linezolid
•MSSA- Oxacillin
•Viral pneumonia: usually supportive treatment
21
25. 1. Ineffective airway clearance related to copious tracheo-
brachial secretions
Goal: To improve airway patency
-Removal of secretions- suctioning if needed
- Adequate hydration of 2 to 3 litres per day thins and
loosens pulmonary secretions.
- Humidified Oxygen
-Coughing exercises
-Chest physiotherapy
- Administer medications as indicated (mucolytics,
expectorants, bronchodilators, analgesics)
-Pulse, oximetry reading (Oxygen sat.)
25
26. 2. Fatigue and activity intolerance related to impaired
respiratory function
Goal: To promote rest and conserve energy
•Encourage avoidance of overexertion adequate rest
•Semi-Fowler’s position comfortability, promote rest
and breathing
•Frequent position change enhance secretion clearance,
pulmonary ventilation and perfusion.
26
27. 3. Risk for deficient fluid volume related to fever and a
rapid respiratory rate
Goal: To promote fluid intake
- Increase in fluid intake to at least 2L per day to replace
insensible fluid losses if not contraindicated (CHF)
- Assess vital sign changes: increasing temperature,
prolonged fever, orthostatic hypotension, tachycardia.
- Monitor intake and output
- Provide supplemental IV fluids as necessary.
27
28. 4. Imbalanced nutrition: less than body
requirements
Goal: To maintain nutrition
•Fluids with electrolytes and nutrition-enriched drinks
provide fluid, calories, and electrolytes.
•Provide small, frequent meals, including dry foods (toast,
crackers) and/or foods that are appealing to patient.
28
29. 5. Deficient knowledge about the treatment regimen and
preventive measures
Goal: To promote patient’s knowledge: Patient and
caregiver will verbalize understanding of condition,
disease process, and prognosis, understanding of the
therapeutic regimen
•Educate patient and family about the cause of pneumonia,
management of symptoms, signs, and symptoms, and the
need for follow-up.
•Educate patient about the factors (risk factors) that may
have contributed to the development of the disease
•Educate patient on the need to complete treatment regimen
