week 6: special projections (chest and abd) Flashcards
Abd lateral decubitus position has the CR enter at ____
2 inches above the iliac crest
Determining air fluid levels in a chest XR requires a completely _____________, as in ____________
erect position with a horizontal CR, PA or decubitus chest
all chest XR are taken with an SID of _______
72 inches
An AP supine or AP semi-erect chest XR is taken with the IR in __________ orientation
portrait or landscape
what is to note about the AP supine/semierect CR for a chest XR?
CR angled caudad to be perpendicular to long axis of sternum (generally a ~5 degree angle)
in an AP supine/semierect chest XR, CR angled ________ to be __________ to long axis of _______ (generally a _______________)
caudad, perpendicular, sternum, ~5 degree angle
with the chest XR in the supine/semi erect position, it is preferred for patient to be (completely supine/adjusted to semi-erect) if possible
adjusted to semi-erect
what are the 3 exceptions noted in the Bontrager book for evaluation criteria of an AP projection of a supine/semi-erect chest XR?
- Heart appears larger due to an increased mag. from shorter SID and increased OID of heart
- Possible pleural effusions for this type of patient often obscures vascular lung markings
- Usually, inspiration is not as full
for an AP projection supine/semi-erect chest XR, correct CR angle leads to ____ being in the same horizontal plane with an ________________
clavicles, unobstructed view of apical regions
SID for all chest XR, standard or special projections
72 inches
IR size for all chest XR, standard or special projections
14x17 inches
A lateral decubitus (AP projection) chest XR is taken with the IR in __________ orientation
landscape

patient positioning notes for lateral decubitus (AP projection) chest XR (2 of 2)
-cart ____
-pillow under patient’s ____
-knees __________
-_______________ with no body rotation
