Unit 2 - CXR & ABD evaluation
Cards in this deck (67)
- 1—Acceptable PA CXR
- 2—Acceptable Lateral CXR
- 3What makes a CXR repeatable?- poor inspiration
- clipping anatomy
- artifacts
- excessive rotation - 4How will a pneumothorax or a pneumonectomy appear on a radiograph?lung will not have any markings, or appear blacked out
- 5what could excessive lung markings on a radiograph indicate?conditions like pulmonary edema, fibrosis, or compression of lung tissue
- 6The air/fluid separation line on a CXR acts similarly to water in a cup, how will it appear on a radiograph?A defined line of brightness against a darkened area of air, it will tilt as the patient tilts
- 7Where will the tip of an endotracheal (air) tube be positioned in the lungs?1-2 in. superior to the carina
- 8Where will the tip of a pleural drainage (fluid) tube be placed?between 5th and 6th intercostal spaces
- 9How is the diaphragm positioned on a hypersthenic patient?high
- 10How is the diaphragm positioned on an asthenic patient?low
- 11How will the midcoronal plane be positioned against the IR to prevent rotation and keep the lung fields symmetric on a PA CXR?plane is parallel to the IR
- 12How can you determine rotation on a PA CXR?SC joints should be level and symmetric
- 13If a patient is rotated to the right for a PA CXR, how will the SC joints appear on the radiograph?the RIGHT SC joint will be superimposed within the spine
the LEFT SC joint will be free of superimposition
the LEFT lungs will be elongated because they are farther away from the IR - they will be magnified - 14How can you tell if the patient's shoulders were elevated on a PA CXR?the clavicles are level and the manubrium is at T2-3 with only about an inch of apex seen above clavicle
______________________________________
When shoulders are elevated, the lateral sides of the clavicles are elevated - 15If the superior portion of a patient's midcoronal plane is tilted forward towards the IR, how will the radiograph appear?manubrium situated @ T5 or lower
more than 1 in. of apex will be seen above the clavicles - 16If the superior portion of a patient's midcoronal plane is tilted backward away from the IR, how will the radiograph appear?manubrium situated @ T1-2 or higher
less than 1 in. of apex will be seen above the clavicles - 17Which directions will the lungs expand?Transversely
Anteroposteriorly
Vertically - 18Which direction of lung expansion is the greatest?Vertical
- 19Which pathology would require a PA CXR with expiration?pneumothorax
foreign body localization - 20How will the midcoronal plane be positioned with the IR to prevent rotation on a LAT CXR?midcoronal plane is perpendicular to IR
- 21What's the best way to determine rotation on a LAT CXR?if there's more than 0.5 in. of space between the posterior ribs and spine
- 22How can you tell if the patient was rotated to the LEFT for a LAT CXR?The heart shadow will extend anteriorly past the sternum
- 23How can you tell if the patient was rotated to the RIGHT for a LAT CXR?The gastric bubble will appear under the right hemidiaphragm, and the right lung will extend anteriorly beyond the sternum
- 24On a well inspired LAT CXR, where will the hemidiaphragm be seen?below T11
- 25Which way is the patient rotated?Right side is more anterior
- 26Which way is the patient rotated?Left side is more anterior
- 27Which way is the superior midcoronal plane tilted?FORWARD
- 28Which way is the superior midcoronal plane tilted?BACKWARD
- 29Which way is the patient rotated?RIGHT SIDE ANTERIORLY
- 30Which way is the patient rotated?LEFT SIDE ANTERIORLY
- 31Inaccurate CR angulation will _____ or _____ the heart and lungs on an AP CXRelongate or foreshorten
- 32If you have to use a 40-48 SID for an AP CXR, how will the image appear?heart will be magnified
- 33If your CR is angled too caudal on an AP CXR, how will the image look?manubrium will be inferior to T4
more than 1 in. of apex will be seen above clavicle
posterior ribs will be more vertical - 34If your CR is angled too cephalic on an AP CXR, how will the image look?manubrium will be superior to T4
less than 1 in. of apex will be seen above the clavicle
posterior ribs will be more horizontal - 35What's wrong with this AP CXR?the CR was angled too caudal
- 36What's wrong with this AP CXR?pt. leaned to the left,
shoulders elevated
- 37If there's fluid in right lung, which decubitus CXR would you perform?Right lateral decubitus
fluid falls - 38If there's fluid in the left lung, which decubitus CXR would you perform?Left lateral decub
fluid falls - 39If there's air in the right lung, which decubitus CXR would you perform?left lateral decubitus
air rises - 40If there's air in the left lung, which decubitus CXR would you perform?right lateral decubitus
air rises - 41How can you determine if the patient was rotated for a decubitus CXR?Whichever side is closer to the IR will have elongated posterior ribs, and the SC joint will be least superimposed by the vertebral column
- 42Which side of the patient is rotated closer to the IR?LEFT
- 43How can you determine if the patient was properly positioned for an AP Lordotic CXR?The clavicles should be level completely out of the lung field
- 44What's the positioning error on this AP Lordotic CXR?Patient's midcoronal plane is NOT at a 45 degree angle with the IR (not leaned back enough)
- 45How is rotation determined on an ABD xray?The iliac wing that's longer is the side that's rotated closer to the IR
- 46Which way is the pt rotated?RIGHT
- 47What's wrong with this ABD XR?overexposed
patient off centered
motion
- 48What's wrong with this ABD XR?underexposed
clipped diaphragm
- 49Which side should be down on a lateral decubitus ABD and why?Left Side Down
because the gastric bubble is on the left side, so we don't want to confuse it with possible free air in the ABD - 50How can you determine rotation on a Decubitus ABD XR?Iliac Wings
Spinous Processes - 51Which side of the patient is closer to the IR?Left side
- 52What's wrong with this decub ABD XR?left side cut off
bra artifact
- 53What's the repeatable error in this decub ABD XR?Diaphragm cut off
