Assessment of the Lungs and Thorax Flashcards
1
Q
the thoracic cage consists of
A
- 12 thoracic vertebrae
- 12 pairs of ribs
- sternum
2
Q
how to the ribs connect to the thoracic cage
A
posteriorly
3
Q
what are the floating ribs
A
11th and 12th rib
4
Q
the ribs are connected to the sternum by
A
costal cartilage
5
Q
what are the 3 components of the sternum
A
- manubrium
- body
- xiphoid process
6
Q
intercostal space
A
the space between the ribs
7
Q
suprasternal notch
A
- u-shaped depression at the ventral aspect of the neck, just above the manubrium
8
Q
manubriosternal junction (angle of louis
A
- junction between manubrium and sternum; useful for rib identification
9
Q
anterior chest wall topographic markers
A
- nipples
- suprasternal notch
- manubriosternal junction (angle of louis)
- midsternal line
- costal angle
- clavicals
- midclavicular lines
10
Q
midsternal line
A
- imaginary vertical line through the middle of the sternum
11
Q
costal angle
A
- intersection of the costal margins
- usually no more than 90 degrees
12
Q
midclavicular lines
A
- imaginary vertical lines on right and left sides of chest that are “drawn” through the clavicle midpoints, parallel to the mensternal line
13
Q
a costal angle of more than 90 degrees is indicative of
A
emphysema
13
Q
lateral chest wall topographic markers
A
- anterior axillary lines
- posterior axillary lines
- midaxillary lines
13
Q
anterior axillary lines
A
- imaginary lines on the right and left sides of the chest “drawn” from the anterior axiallry fold through the anterolateral chest, parallel to the midsternal line
