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

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
Q

empyema

A

puss in pleural space

26
Q

Pneumonia is common with…

A

the very young or very old

27
Q

Infants and penumonia

A

immature immune system

28
Q

Elderly and pneumonia

A

decreased cough and gag

29
Q

Risk factors of Pneumonia

A
  • infants, elderly
  • HIV/Aids
  • cancer, organ transplant
  • chronic illnesses (DM, cardiac, respiratory)
  • endotracheal intubation (ventilator associated pneumonia - VAP)
  • NG tubes
  • Smoking, alcoholism
30
Q

Prevention

A
  • Early identification and appropriate treatment

- Vaccines

31
Q

Vaccines

A
  • Pneumococcal
  • PCV13—children under 2 yrs.
  • PPSV23—adults
  • Hib—children under 2 yrs.
  • Influenza
32
Q

Clinical Manifestations

A
  • fever and chills
  • cough (productive and purulent)
  • chest pain
  • blood-tinged sputum
  • SOB
  • decreased appetite
  • cyanosis
  • crackles
  • wheezing
33
Q

Lifespan Considerations: Infants and Children

A
  • 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
Q

Lifespan considerations: Older Adults

A
  • decreased cough and gag
  • thick, viscous secretions
  • decreased cilia
  • meds, H/O smoking, COPD
35
Q

Diagnostic Studies for Pnemonia

A
  • CXR
  • CT Scan
  • Sputum C&S and Gram stain
  • CBC with diff
  • Serology (pathogen antibodies)
  • Pulse Ox
  • ABG
  • Bronchoscopy
36
Q

Pharmacologic Therapy

A

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
Q

CPT Includes

A
  • percussion
  • vibration
  • postural drainage
38
Q

Nursing Assessment

A
  • VS
  • LOC
  • skin color and temp
  • respiratory distress
  • lung sounds
  • consolability (infants)
39
Q

Nursing Care

A
  • 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
Q

Cephalosporin and PCNs

A

up to 30% with PCN allergy are also allergic to Cephalosporin

41
Q

Problem with high fowlers

A
  • drainage for lower lobe pneumonia
  • uncomfortable
  • ulcers*****
42
Q

Nursing Care Review for Pneumonia

A
  • Airway management
  • Pain management
  • Fluids and electrolytes
  • Safety initiatives
  • skin assessment
  • oxygen therapy
  • Patient education
