Q

7 pulmonary disease classifications based on etiology

I think this doesn’t need to be fully memorized, just read it a time or two

A
  1. immune (i.e. vasculitis)
  2. infectious
  3. genetic
  4. neoplasm
  5. exposure (ie silica)
  6. pneumothorax
  7. venous thromboembolus

Q

5 general histo patterns of lung disease

A
  1. interstitial inflammation
  2. “airway disease”
  3. vasculitis
  4. focal
  5. granulomatous

For all of the above remember that there is overlap

Q

Chest pain is generally NOT caused by what?

Two pulmonary causes of chest pain that are gradual? Two pulmonary causes of sudden chest pain?

A
  • -chronic lung disease does NOT = chest pain.
    • infectious process or neoplasm = gradual chest pain
  • -PE and pneumothorax = sudden chest pain

Q

Rhonchi:

whats the sound, whats the cause?

A
  • lower pitched “musical noises”.
  • obstruction, usually with mucus secretions.
  • May be seen in acute CHF (which can cause transudate in the airways)

Q 
What are crackles/ rales? 
Common assc (3)?
A

suggest fluid in the lung parenchyma– compresses/ pops the alveoli
-clasically assc with CHF, chronic pulm edema, infection

Q

When might you get fine/ dry crackles?

A

when there is scarring (severe interstitial disease)

describes as “velcrow”

Q

How do effusion and consolidation effect resonance?

A

^^ fluid- HYPOresonance

because sound travels better through GAS than solids/liquids.

Q

How do pneumothorax and emphysema effect resonance?

A

^^ air- HYPERresonance

18
Q

When is a pneumothorax life threatening?

What do you do?

A

“Tension” pneumothoraxes are life threatening; cause rapid cardiopulmonary failure.

  • air ENTERS chest but cannot exit through lung or some outside wound= compression of organs.
  • Needs chest tube, stat
19
Q

What is ruptured in a pneumothorax (PTX)?

A

visceral pleura

20
Q

What are some causes of PTX? (3)

A
  1. spontaneous esp in COPD/ tall people
  2. trauma
  3. iatrogenic
21
Q

What is a pleural effusion?

What causes it? (3)

A

fluid under the lung/ in the pleural space

caused by any inflammatory process, esp tumor, infection, heart failure

22
Q

Pulmonary nodules- #1 cause; 3 others

A 
#1- benign from environmental allergens 
also early malignancy, CT disease, infection
23
Q

Three tumors that may met to the lung?

A

testicular, thyroid, kidney

Remember that colon cancer will go to the liver first; this is intuitive if you think about the anatomy and portal circulation

24
Q

Most common pulmonary pathology of all….

A

viral illnesses

25
Q 
HE WILL ASK THIS A LOT:
Give a quick one word assc for each of these sounds:
1. rales 
2. fine/ dry crackles 
3. rhonchi 
4. wheezing
A

rales/ wet crackles- edema
fine/ dry crackles- interstitial
rhonchi- secretions
wheezing- swelling

MENTIONED 3 FRICKIN’ TIMES

26
Q

What is the word for wheezing heard in the upper airway?

A

stridor! this is what you would call snoring.

27
Q

common viral infection in smokers

A

rhinovirus

28
Q

URI vs LRI: which is most likely to be bacterial?

A

LRI more commonly bacterial; URI mostly viral

29
Q

Influenza infection predisposes the lung to what other pathogen?

A

strep pneumo bacterial pneumonia

30
Q

What three pathogens can act as super antigens?

What do super antigens incite?

A

staph aureus, strep pnuemo, influenza= super antigens

super antigens= sepsis

31
Q

“crackles at the base of the lung”

What is this a classic description of?

A

CHF

32
Q

“Hyporesonance and pain at the base of lung”

What is this a classic description of?

A

Pleural effusion

**“I WILL PROBABLY GIVE YOU A QUESTION LIKE THIS.” - Meadows

33
Q

What would you see on CXR in the case of a pneumothorax?

A

black area without lung lines

34
Q

What would a PFT show in the case of a pleural effusion?

A

-would present like a restrictive disease;

normal FEV1:FVC, low TLC/ DLOC

35
Q

What percentage of RA patients have lung involvement?

A

nearly half.

36
Q

What do acute and chronic heart failure sound like in the lung?

A

Acute: fluid transudate–> ronchi
Chronic: WET CRACKLES at lung base

37
Q

Three causes of finger clubbing?

A

Congenital heart disease, pulm. fibrosis, lung cancer

38
Q

What does it mean if you see an ^ AP diameter on PE?

A

chronic hyperinflation (COPD, emphysema)

39
Q

How long would a cough due to RT irritation typically last in an asthmatic or a smoker?

A

3-8 weeks; will be self limited and you can differentiate this from interstitial disease based on hx

note that when patients say they feel like they need to cough up mucus in this case it is actually just infammation in the airway

40
Q

Phrenic nerve paralysis: how does this present?

What is a common cause?

A

Common on lt side after CABG
You will hear HYPOresonace on percussion exam because you are hitting the liver and the paralyzed diaphragm does not allow lung to expand and fill w air …

41
Q

1 cause of lung cancer ww?

A

biomass smoke– i.e. wood burning stove; think women in honduras
