Q

What are the causes of pneumonia?

Viral vs. Bacterial (ages)

A
  1. VIRAL = RSV, CMV, influ, rhino = ALL AGES
2. Bacterial = group B strep, gram -
neonates = group b strep, listeria
1-3mo = strep pneumo, chlamydia, staph
4mo-5yr = strep pneumo, HIB, M. pneumo
>5 years = mycoplasma pneumo, chlamydophilia pneumo and S. Pneumo
Mycoplasma is usually mild

Q

What are the clinical characteristics of cystic fibrosis?

( define, leads to…11)

A
  1. Autosomal recessive, dysregulation of chloride channels, dehydrated/viscous secretions in the airways, bile ducts, pancreas, intestines, vas deferens, sweat glands
  2. Leads to chronic pulmonary disease, nasal polyps, malnutrition, steatorrhea, biliary cirrhosis, male infertility, increased sweat production, pancreatitis, poor growth, diabetes, rectal prolapse
17
Q

How is CF diagnosed and tx? (2)

A
  1. DX with sweat test (could be from newborn screen), fam hx, and mutation detection
  2. Refer to CF center, antibiotics to cover pseudomonas (Ciprofloxin+aerosolized tobramycin), chest PT, pancreatic enzymes, nut support

  3. Exploratory phase > Inspiratory phase
25
Q

Bronchovesicular Breath Sounds (4)

A
  1. Heard in posterior chest between scapula and center part of anterior chest

  3. Inspiration = Expiration
  4. Difference in pitch and intensity is more equally detected in expiration
26
Q

Vesicular Breath Sounds (3)

A
  1. Soft, blowing or rustling sound over most lung fields
  2. Normally heard throughout inspiration and continues without pause through expiration but fades 1/3 into expiration
  3. Inspiration > expiration
27
Q

Fine crackles/Rales (3)

A
  1. Short, rattling sounds best heard on mild to late inspiration and occasionally on expiration
  2. Unaffected by cough
  3. Pneumonia and intersitial lung disease
28
Q

Coarse crackles (3)

A
  1. Short, explosive heard early inspiration and throughout expiration; intermittent bubbling or brief popping that lasts longer than fine crackles
