✍️ Sample GXMO Questions & Answers
1. What makes a professional competent in X-Ray Equipment Operation?
Competence requires the integration of knowledge, skills, experience, and professional conduct.
2. What is the primary effect of increasing the kVp (kilovoltage peak) setting on an X-ray image?
Increasing the kVp (kilovoltage peak) setting increases the energy and penetrating power of the X-ray beam. This allows more X-rays to pass through denser tissues, resulting in a wider range of gray shades and thus decreasing the overall image contrast. While penetration increases, the differences between tissue densities become less pronounced, leading to a 'longer scale' of contrast.
3. What is the primary purpose of standardized procedures in Image Quality?
Standardized procedures ensure that all practitioners deliver consistent, safe, and high-quality outcomes.
4. Which approach is most effective for problem-solving in Image Quality?
Systematic, evidence-based approaches lead to more reliable solutions than ad hoc methods.
5. A patient with an indwelling urinary catheter is being positioned for a pelvic radiograph. The technologist should:
The catheter bag must remain below bladder level to allow gravity drainage, and the tubing must not be pulled or kinked during positioning.
6. Which exposure factor most directly controls motion blur (voluntary or involuntary patient movement)?
Exposure time determines how long the patient is irradiated; shorter exposure times minimize the opportunity for motion to blur the image.
