Q

Recurrent laryngeal nerve wraps around what on each side?

A

right: subclavian artery

17
Q

Tracheal branches at what vertebral level?

A

T4/T5

18
Q

What is the point of separation where trachea splits

A

carina

19
Q

If you inhale something, into which 1˚ bronchus is it going to go?

A

right, angled more vertically

left has to go around the heart

20
Q

Is lymphatic drainage of lung segmental like airway and blood flow?

A

NO!

may have fluid buildup after partial resection of lung

21
Q

Does lymph flow from one lung to the other?

A

yes

some lymph nodes connect the right and left lung

22
Q

Etiology of spontaneous pneumothorax

A

ruptured bulla

air escapes from lung into pleural space

or something pathology crossing lung parenchyma

23
Q

What is it called when you have a stab wound and get a pneumothorax from outside air?

A

open pneumothorax

mediastinal structures move with inspiration to unaffected side and back with expiration

24
Q

Etiology of tension pneumothorax

A

some structure acting like valve, cannot escape

mediastinal structures moved over

compression of great vessels

25
Q

Tx of tension pneumothorax

A

tube thoracostomy

4th or 5th intercostal space

26
Q

Pleural effusion

A

increase of fluid in the pleural space

27
Q

Hemothorax

A

blood entering the pleural sapce
