Workbook Final Exam Review Flashcards
A ___ is an image of a patient’s anatomic parts as produced by the actions of x-rays on an IR
Radiograph
The ___ is the aspect of an x-ray beam that has the least divergence (unless there is angulation)
CR
true or false: the base plane of the skull is a transverse plane located between the infraorbital margin of the orbits and the superior margin of the external auditory canal (EAM)
True
True or false: the Frankfort horizontal plane is also referred to as the occlusal plane
False
The direction or path of the central ray defines the following positioning
a. Projection
b. View
c. Position
d. Perspective
a. projection
The positioning term that describes the general and specific body position is
a. projection
b. view
c. position
d. perspective
c. position
true or false: oblique body and lateral positions are describes according to the side if the body closest to the IR
True
true or false: decubitus positions always use horizontal x-ray beam
true
what is the name of the position in which the body is turned 90 degrees from the true AP or PA projection
lateral position
a patient is erect with the beck to the IR. The left side of the body is turned 45 degrees toward the IR. What is this position?
LPO
a patient is recumbent facing the IR. The right side of the body is turned 15 degrees toward the IR. What is this position?
RAO
The patient is lying on his back. The x-ray beam is directed horizontally and enters the right side and exists the left side of the body. An IR is placed against the left side of the patient. What specific position has been performed?
Dorsal Decubitus / Left lateral
The patient is erect with the right side of the body against the IR. The x-ray beam enters the left side and exists the right side of the body. Which specific position has been performed?
Right lateral
a patient on a cart is lying on the left side. The x-ray beam is directed horizontally and enters the posterior surface and exists the anterior aspect of the body. The IR is against the anterior surface. Which specific position has been performed?
PA left lateral decubitus
define tredelenburg
position in which the head is lower than the feet
define Fowler
position in which the head is higher than the feet
a projection using a CR angle of >/ 10 degree directed parallel along the long axis of the body or body part is termed an ____ projection
axial
the specific position that demonstrates the apices of the lungs, without superimposition of the clavicles is termed an ___ positon
lordotic
true or false: radiographic view is not a correct positioning in the US
true
true or false:the term varus describes the bending part of the part outward
false
is AP projection or positon?
projection
is prone projection or positon?
position
is tredelenburg projection or positon?
position
is LPO projection or positon?
position
is left lateral chest projection or positon?
position
is mediolateral ankle projection or positon?
projection
is tangential projection or positon?
projection
is lordotic projection or positon?
position
is inferosuperior projection or positon?
projection
is left lateral decubitus projection or positon?
position
list the 2 rules or principles for determining positioning routines as they relate to the maximum number of projections required in a basic routine
- minimum of 2 projections 90 degrees from each other
- minimum of 3 projections when joints are in prime interest area
A young child enters the emergency room with a fractured forearm. After one projection is completed that confirms a fracture, the child refuses to move the forearm for any additional projections.
What is the minimum number of projections that must be taken for this forearm study?
2
A young child enters the emergency room with a fractured forearm. After one projection is completed that confirms a fracture, the child refuses to move the forearm for any additional projections.
If additional projections are required for a routine forearm series, what should the technologist do with the young patient?
rather than move the forearm for a second projection, place the IR and x-ray tube as needed for a second projection 90 degrees from the first projection
