Gxmo Ohio review Questions and
Answers 100% Pass
Contrast - ✔✔The difference between any two adjacent portions of the image
Attenuation - ✔✔Absorption of the X-ray beam by matter
Scatter radiation - ✔✔Part of the X-ray beam that scatters in opposite direction, from the
patient. Has less energy than primary beam. Not easily controlled
Detent - ✔✔Special mechanism that stops the X-ray tube in a specific location.
Trendelenburgs position - ✔✔Flat on back with head lower 15 degrees
Grid - ✔✔Device that absorbs most of the scatter radiation coming off pt, preventing it
from reaching IR. Increases pt exposure.
Floating tabletop - ✔✔Allows the top of X-ray table to move independently, which
makes it easier to align body part
Bucky - ✔✔Grid and pull out tray to hold the IR plate and center it to Central ray
Stationary grid - ✔✔Grid that does not move during exposure

, When to use a grid? - ✔✔10-12 cm or more in thickness or when kVp greater than 60
Upright cassette holder *UPRIGHT BUCKY* - ✔✔Hold IR in upright position. Mounted
on wall and able to be adjusted for height at 40 or 72 SID
Control console *panel* - ✔✔Where the limited operator sets exposure factors and
Initiates the exposure
Transformer cabinet - ✔✔Used to produce high voltage required for X-ray production
Fundamental rad safety - ✔✔The potential hazard is greater for the limited operator
than the pt because the limited operator is in frequent daily contact
Sources of radiation - ✔✔X-ray tube and any matter that is in the path of the X-ray
beam
Principle source of scatter? - ✔✔The patient
Should the limited be involved in holding patients? - ✔✔No never. Immobilization
devices or the patients family if need be
What should the GXMO do before making an exposure? - ✔✔Perform a safety check.
Make sure the X-ray door is closed. No one in X-ray room. Your completely behind
Barrier. No other IRs in the exposure area.
The source of X-rays? - ✔✔In a very small area inside the X-ray tube.
