Radiographic Positioning Test

Posted on Updated on

Question 1 (1 point)  If a bone is projected longer or shorter than it actually is on the radiographic image, it is known as: Question 1 options:   Angulation   Anatomic Position   Distortion   Recorded Detail

Question 2 (1 point)  Radiographs of the hands, wrist, feet, and toes are routinely displayed on the illuminator with the digits: Question 2 options:   Positioned towards the ceiling   Positioned towards the floor   Horizontal towards the right   Horizontal towards the left

Question 3 (1 point)  What are the two controlling factors of magnification? Question 3 options:   Density and Contrast   SID and OID   Central ray angle and central ray alignment   Part/image receptor alignment and SID

Question 4 (1 point) Collimation of the x-ray beam prompts which of the following: (1) an increase in radiographic contrast (2) reduction of scatter and secondary radiation (3) reduction in radiation to the patient Question 4 options:   1 & 2   1 & 3   2 & 3   1, 2 & 3

Question 5 (1 point)  Where should the lead marker be placed when performing an AP Oblique projection of the cervical vertebrae? Question 5 options:   The R marker is always used   The L marker is always used   Always mark the side closest to the IR   Always mark the side farthest from the IR

Question 6 (1 point)  Involuntary motion can be caused by which of the following? (1) peristalsis (2) spasm (3) breathing Question 6 options:   1 & 2   1 & 3   2 & 3   1, 2, & 3

Question 7 (1 point) How should a PA projection radiograph of the chest be displayed? Question 7 options:   As viewed from the perspective of the x-ray tube   So that the side of the patient that is closer to the IR during the procedure is the side of the image closer to the display device   As though the patient was standing in front of the viewer, with the patient’s right side aligned with the viewer’s right side and the patient’s left side aligned to the viewer’s left side   As though the patient was standing in front of the viewer, with the patient’s right side aligned with the viewer’s left side and the patient’s left side aligned with the viewer’s right side

Question 8 (1 point)  How should a left lateral projection radiograph of the chest be displayed? Question 8 options:   As though the patient were standing in front of and facing to the left of the viewer.   As though the patient were standing in the normal anatomic position, face to face with the viewer.   So that the side of the patient where the x-ray beam enters  is the side of the image closer to the viewbox.   So that the side of the patient closer to the IR during the procedure is the side of the image closer to the viewbox.

Question 9 (1 point) Which factor controls radiographic contrast? Question 9 options:   Exposure Time   mA   SID   kVp

Question 10 (1 point) Which radiographic term refers to the degree of blackness between two adjacent areas on a radiograph? Question 10 options:   Density   Contrast   Magnification   Recorded detail
