1
Q

Pneumonia

A
  • Acute inflammation of the lung parenchyma
  • may be infectious or non-infectious
  • was #1 COD in US until antibiotics in use….now #8
  • Approx. 50,000 people die yearly
  • cost is $20 billion annually

Q

To get pneumonia…

A
  • microbes are either inhaled or aspirated from oropharynx
  • mat also enter via bloodstream
  • host defenses overwhelmed

Q

Normal defenses against penumonia

A
  • cough reflex (aspiration pnem)

Q

Viral Characterisitics

A
  • enter from upper airway and infiltrate alveoli in one or both lungs
  • invade cells and kill them, send out debris
  • patchy distribution
  • influenza and adenovirus

17
Q

Other causes of infectious pneumonia

A

fungi and protozoa

18
Q

Aspiration

A

food, emesis, reflux, hydrocarbons

-may be infectious or non-infectious; chemical injury and inflammatory response

19
Q

hydrocarbons

A

household cleaners

kids

20
Q

Pneumonia complications

A
  • bronchiectasis
  • pleuritis
  • pleural effusion
  • lung abscess
  • empyema
21
Q

bronchiectasis

A

walls of bronchi get thickened from inflammation and infection

22
Q

pleuritis

A

inflammation of actual pleura

23
Q

pleural effusion

A

fluid in pleural space

24
Q

lung abscess

A

bacteria pneumonia

-pocket within lung tissue

25
empyema
puss in pleural space
26
Pneumonia is common with...
the very young or very old
27
Infants and penumonia
immature immune system
28
Elderly and pneumonia
decreased cough and gag
29
Risk factors of Pneumonia
- infants, elderly - HIV/Aids - cancer, organ transplant - chronic illnesses (DM, cardiac, respiratory) - endotracheal intubation (ventilator associated pneumonia - VAP) - NG tubes - Smoking, alcoholism
30
Prevention
- Early identification and appropriate treatment | - Vaccines
31
Vaccines
- Pneumococcal - PCV13—children under 2 yrs. - PPSV23—adults - Hib—children under 2 yrs. - Influenza
32
Clinical Manifestations
- fever and chills - cough (productive and purulent) - chest pain - blood-tinged sputum - SOB - decreased appetite - cyanosis - crackles - wheezing
33
Lifespan Considerations: Infants and Children
- airway shorter and more narrow - high risk of obstruction - Higher O2 consumption - Tachypnea, intercostal retractions, nasal flaring - Dx: blood cultures - usually bacterial - recover faster than adults - common in kids with CF
34
Lifespan considerations: Older Adults
- decreased cough and gag - thick, viscous secretions - decreased cilia - meds, H/O smoking, COPD
35
Diagnostic Studies for Pnemonia
- CXR - CT Scan - Sputum C&S and Gram stain - CBC with diff - Serology (pathogen antibodies) - Pulse Ox - ABG - Bronchoscopy
36
Pharmacologic Therapy
Depends on microbe - PCN - Cephalosporins - EES - TMP-SMZ - Azithromycin - Clindamycin - Med may change after gram stain/culture results obtained - Bronchodilators - Acetylcysteine (reduce mucous viscosity) - Expectorants - Oxygen - Liquids (2.5-3 L/day) - incentive spirometer - chest physiotherapy
37
CPT Includes
- percussion - vibration - postural drainage
38
Nursing Assessment
- VS - LOC - skin color and temp - respiratory distress - lung sounds - consolability (infants)
39
Nursing Care
- antibiotics as ordered--ask about allergies - Antipyretics - I&Os - encourage fluids - Assess sputum color - Ongoing respiratory assessment - Fowlers or high fowlers position - deep breach cough - suction - assess for pleuritic pain - use pillow for splint when coughing - O2 as needed - Teaching: smoking cessation, vaccines
40
Cephalosporin and PCNs
up to 30% with PCN allergy are also allergic to Cephalosporin
41
Problem with high fowlers
- drainage for lower lobe pneumonia - uncomfortable - ulcers*****
42
Nursing Care Review for Pneumonia
- Airway management - Pain management - Fluids and electrolytes - Safety initiatives - skin assessment - oxygen therapy - Patient education
