Term
| Name several specific criteria for evaluating a PA chest X-ray: |
|
Definition
1. Lungs - costaphrenic angles / apices
2. Vascular markings
3. SC joints equidistant to spine
4. 10 posterior ribs
5. MSP
6. Marker
7. Shoulders rolled forward
8. Collimated |
|
|
Term
| Why should a routine CXR be done on full inspiration? |
|
Definition
1. Diaphragm moves inferiorly
2. Costal muscles expands thorax
3. More air with less strain on 2nd inspiration |

Term
| Which phase of respiration removes air from the lungs? |
|
Definition
|
|
Term
| When using the phase of respiration that removes air, the diaphragm will move __________. |
|
Definition
|
|
Term
| Why is a left lateral chest projection preferable to a right lateral? |
|
Definition
| Places heart closer to IR, reduces magnification. (Larger OID increases magnification) Also used to show the heart, aorta, and left sided pulmonary lesions |
|
|
Term
| Why do we do a routine chest x-ray at an SID of six feet? |
|
Definition
| To decrease magnification of the heart |

|
Definition
down
* fluid-side down, air-side up |
|
|
Term
