, INTRODUCTION
The purpose of this examination is to evaluate the clinical competency and technical
proficiency of radiologic technologists. This assessment covers essential knowledge in
radiation safety, anatomy, image optimization, and patient management. By utilizing a
mix of multiple-choice and scenario-based questions, the exam tests the candidate's
ability to apply theoretical concepts to real-world clinical situations. Emphasis is placed
on critical thinking, decision-making, and adhering to professional ethical standards. This
practice document ensures that practitioners are prepared to maintain high-quality
diagnostic standards, prioritize patient welfare, and uphold regulatory compliance in
diverse healthcare settings.
SECTION ONE: QUESTIONS 1–100
1. Which of the following is the primary objective of ALARA principles in radiography?
A. Increasing image resolution at any cost
B. Keeping radiation doses as low as reasonably achievable
C. Maximizing equipment lifespan
D. Reducing the need for repeat exposures
🟢 B. Keeping radiation doses as low as reasonably achievable
🔴 RATIONALE: ALARA stands for As Low As Reasonably Achievable, which is the
, foundational radiation safety principle to minimize patient and staff exposure while
maintaining diagnostic quality.
2. A patient is unable to stand and requires a lateral chest radiograph. Which position
is most appropriate?
A. Left lateral decubitus
B. Dorsal decubitus
C. Trendelenburg
D. Fowler's
🟢 A. Left lateral decubitus
🔴 RATIONALE: The left lateral decubitus position is standard for demonstrating
air-fluid levels in the chest when a patient cannot stand upright.
3. Which interaction with matter contributes most to occupational dose?
A. Photoelectric effect
B. Compton scattering
C. Pair production
D. Photodisintegration
🟢 B. Compton scattering
🔴 RATIONALE: Compton scattering is the primary source of scatter radiation in
the diagnostic range, which creates the radiation hazard for radiographers in the
room.
, 4. If a patient is injured due to a technologist’s failure to provide the standard of care,
the technologist may be held liable under which legal doctrine?
A. Res ipsa loquitur
B. Negligence
C. Strict liability
D. Informed consent
🟢 B. Negligence
🔴 RATIONALE: Negligence occurs when a professional fails to provide the
expected standard of care, resulting in harm to the patient.
5. Which grid ratio would require the highest increase in mAs?
A. 5:1
B. 8:1
C. 12:1
D. 6:1
🟢 C. 12:1
🔴 RATIONALE: Higher grid ratios are more efficient at cleaning up scatter but
require a greater increase in radiation dose to compensate for the absorbed
primary beam.
6. The "anode heel effect" is best described by which statement?
A. Radiation intensity is greater at the anode side
B. Radiation intensity is greater at the cathode side
C. The image is brighter on the anode side
