Ohio GXMO Study Guide Review
Questions and Answers Latest Version
100% Verified
What is the purpose of the GXMO certification in Ohio?
✔✔The GXMO certification in Ohio allows individuals to perform basic radiologic procedures
under the supervision of a licensed radiographer.
What is required for a GXMO to perform a radiographic exam in Ohio?
✔✔A GXMO must work under the supervision of a licensed radiographer and have completed
the necessary education and certification requirements.
What is the maximum exposure limit for a patient during a radiographic procedure?
✔✔The maximum exposure limit is determined by the ALARA (As Low As Reasonably
Achievable) principle, which ensures that radiation exposure is minimized.
What should a GXMO do if a patient refuses an X-ray procedure?
✔✔The GXMO should inform the supervising radiographer and ensure that the patient’s
decision is respected.
1
,What is the primary reason for proper patient positioning in radiographic exams?
✔✔Proper patient positioning ensures that the correct area of the body is imaged and that the
image quality is optimal for diagnosis.
How does collimation affect the quality of a radiographic image?
✔✔Collimation reduces the amount of radiation exposure to areas outside the area of interest,
improving image quality and reducing scatter radiation.
What is the standard SID (Source-to-Image Distance) for most radiographic exams?
✔✔The standard SID is typically 40 inches for most radiographic exams, though this may vary
depending on the procedure.
How should a GXMO handle a situation where a patient is unable to hold their breath during an
X-ray?
✔✔The GXMO should ensure that the patient is as comfortable as possible and repeat the
exposure as needed, following proper technique.
What is the purpose of shielding in radiography?
2
,✔✔Shielding helps to protect parts of the body from unnecessary radiation exposure during an
X-ray procedure.
What does the term "radiation dose" refer to?
✔✔Radiation dose refers to the amount of radiation the patient receives during an imaging
procedure, which should be kept as low as possible to avoid harm.
What should a GXMO do if a radiographic image is unclear or of poor quality?
✔✔The GXMO should consult with the supervising radiographer to ensure the proper procedure
is followed and the image is re-executed if necessary.
How is the effectiveness of a radiographic image determined?
✔✔The effectiveness of an image is determined by its ability to clearly show the anatomy being
imaged, without excessive exposure or distortion.
What is the role of the radiologic technologist in infection control during imaging procedures?
✔✔The radiologic technologist must follow infection control protocols, including sanitizing
equipment and practicing hand hygiene to prevent cross-contamination.
3
, What does "ALARA" stand for, and why is it important?
✔✔ALARA stands for "As Low As Reasonably Achievable," and it is important because it helps
minimize radiation exposure to patients and staff while still providing high-quality images.
What is the difference between a diagnostic X-ray and a therapeutic X-ray?
✔✔Diagnostic X-rays are used for imaging purposes, while therapeutic X-rays are used for the
treatment of medical conditions, such as cancer.
What is the role of the supervising radiographer in relation to the GXMO?
✔✔The supervising radiographer is responsible for overseeing the GXMO's work, ensuring
proper technique, and ensuring patient safety during radiographic procedures.
What is the main focus when performing radiographic procedures on pediatric patients?
✔✔The main focus is to minimize radiation exposure while ensuring proper positioning and
cooperation from the child.
How should a GXMO handle a patient with a known allergy to contrast agents?
✔✔The GXMO should inform the supervising radiographer immediately, who will assess the
situation and determine an appropriate course of action.
