GXMO STUDY GUIDE II UPDATED
ACTUAL Exam Questions and CORRECT
Answers
The link has been demonstrated in animal studies; Increased risk to humans cannot be predicted
with respect to an individual - CORRECT ANSWER - A link between radiation dose and
genetic effects
Increase kVP by 30% - CORRECT ANSWER - ____ will result in the greatest reduction
of patient dose, when millimpere-seconds (mAs) is adjusted to compensate for the change?
Faster speed IR system - CORRECT ANSWER - ___ will result in the lowest patient
dose?
Reduce the likelihood of genetic effects - CORRECT ANSWER - What is the primary
purpose of using gonad shields during radiography
Contact; Shadow - CORRECT ANSWER - Types of gonad shields
When the gonads are within 5 cm of the radiation field - CORRECT ANSWER - When
should gonad shielding be used?
repeat exposures - CORRECT ANSWER - The greatest cause of unnecessary radiation to
patients that can be controlled by the limited operator is:
clearly instructing patients - CORRECT ANSWER - The limited operator can reduce
repeat exposures by:
Limits the radiation field to the area of interest - CORRECT ANSWER - How does x-ray
beam restriction minimize patient exposure?
, Collimator - CORRECT ANSWER - What is the device that allows the limited operator to
vary the size of the radiation field
Removes longer-wavelength photons - CORRECT ANSWER - How does filtration reduce
patient exposure
2.5 mm Al equiv - CORRECT ANSWER - What is the National Council on Radiation
Protection and Measurements (NCRP) recommendation for the amount of total filtration?
Time, distance, shielding - CORRECT ANSWER - What are the three principal methods
used to protect limited operators from unnnecssary radiation exposure?
Apron, Glove, Thyroid shield - CORRECT ANSWER - What are types of personnel
radiation shielding
Scattered radiation from the patient - CORRECT ANSWER - Personnel shielding must be
worn on the rare occasion on which the limited operator may need to remain in the radiographic
room during an exposure to assist the patient in maintianing the proper position. What is the
source of the greatest radiation hazard under this circumstance?
Leakage - CORRECT ANSWER - What is the term for radiation that escapes from the x-
ray tube housing
They are considered occupationally exposed individuals - CORRECT ANSWER - Why
are limited operators prohibited from activities that result in direct exposure to the primary x-ray
beam
the operator should maximize the distance from the source during an exposure - CORRECT
ANSWER - Distance as a method used to limit operator exposure, means that:
