GXMO OHIO ACTUAL EXAM PAPER FULL
QUESTIONS AND CORRECT ANSWERS
2026
◉ Correct radiographic density
Answer: Neither too dark nor too light
◉ Correct contrast
Answer: Makes all anatomy more visible neither flat and grey or too
black and white. Provides sufficient differences in density to easily
make out details in all portions of image.
◉ Structures with great tissue density *bone*
Answer: Absorb more radiation than less dense *muscle*
◉ Remnant radiation or exit radiation
Answer: Forms the latent image on the IR, by passing through
opposite side of pt.
◉ Prime factors of radiation-
Answer: mA, time, kVp, and SID
, ◉ mA controls-
Answer: Filament heat/electrical current that flows through the
tube
The flow rate of electrons across the tube
The rate of X-ray production
◉ mA=
Answer: QUANTITY
◉ Exposure time secs or msecs
Answer: Controlled by tune in X-ray circuit
Directly proportional with quantity
◉ Radiographic phantom is
Answer: A human skeleton or portion of skeleton encase in a plastic
material with tissue density similar to humans
◉ Caliper
Answer: Tool used for body part measurement
◉ Optimum kVp
