Introduction
The purpose of this comprehensive examination is to rigorously evaluate the
candidate's mastery of foundational radiologic technology concepts, safety
regulations, and clinical protocols outlined in chapters one through three. This
assessment measures essential skills and knowledge required for safe,
competent clinical practice, encompassing both core theoretical concepts and
complex clinical scenarios. Utilizing a robust format of multiple-choice and
scenario-based questions, the exam emphasizes real-world application, critical
thinking, and rapid clinical decision-making. Candidates are tested on their
ability to integrate radiation safety practices, ethical standards, and technical
imaging principles to ensure optimal patient outcomes and regulatory
compliance in healthcare environments.
SECTION ONE: QUESTIONS 1–100
Question 1
Which of the following professional organizations is primarily responsible for
establishing and maintaining national standards of practice and the code of
ethics for radiologic technologists?
A. American Board of Radiology
B. American Registry of Radiologic Technologists
C. Joint Review Committee on Education in Radiologic Technology
D. American Society of Radiologic Technologists
,🟢 D. American Society of Radiologic Technologists
🔴 Explanation: The American Society of Radiologic Technologists develops the
practice standards, curriculum, and code of ethics for the profession, while the
American Registry of Radiologic Technologists is the certifying body for
credentialing.
Question 2
A radiologic technologist enters a patient's room and notices the patient is
confused and attempting to stand unassisted from a wheelchair, posing an
immediate fall risk. What is the most appropriate initial action?
A. Immediately apply soft wrist restraints to secure the patient.
B. Leave the room to locate a nurse for assistance.
C. Stay with the patient, provide verbal reassurance, and request immediate
assistance.
D. Instruct the patient firmly to sit back down without approaching them.
🟢 C. Stay with the patient, provide verbal reassurance, and request immediate
assistance.
🔴 Explanation: Patient safety is the top priority; staying with the confused
patient prevents a fall while calling or signaling for help ensures safe, immediate
assistance without leaving the patient vulnerable.
Question 3
What is the primary biological effect of ionizing radiation on living tissue at the
atomic level?
A. Thermal destruction
B. Ionization of atoms and molecules
C. Molecular resonance
D. Optical excitation
🟢 B. Ionization of atoms and molecules
🔴 Explanation: Ionizing radiation possesses sufficient energy to remove orbital
electrons from atoms, creating ion pairs that can disrupt cellular structures and
cause biological damage.
Question 4
Under the legal doctrine of res ipsa loquitur, which of the following must be
proven by the plaintiff in a medical malpractice lawsuit?
,A. The injury was caused by third-party negligence outside the hospital.
B. The injury would not ordinarily occur in the absence of negligence, the
agency was under the exclusive control of the defendant, and the plaintiff did
not contribute to the injury.
C. The technologist intentionally harmed the patient during the procedure.
D. The patient signed an informed consent form before the incident occurred.
🟢 B. The injury would not ordinarily occur in the absence of negligence, the
agency was under the exclusive control of the defendant, and the plaintiff did
not contribute to the injury.
🔴 Explanation: Res ipsa loquitur translates to "the thing speaks for itself" and
applies when an injury clearly implies negligence and the instrumentality was
solely in the defendant's control.
Question 5
Which imaging system component is primarily responsible for converting
remnant radiation into an electrical signal in modern digital radiography flat-
panel detectors?
A. Intensifying screen
B. Photomultiplier tube
C. Thin-film transistor array and scintillator or photoconductor
D. Vacuum tube cathode filament
🟢 C. Thin-film transistor array and scintillator or photoconductor
🔴 Explanation: Direct and indirect digital radiography detectors use active
matrix arrays featuring thin-film transistors combined with photoconductors or
scintillators to capture and convert radiation into digital signals.
Question 6
What is the legal term used to describe a civil wrong committed by one
individual against the person or property of another, which may result in a
lawsuit for damages?
A. Felony
B. Tort
C. Misdemeanor
D. Subpoena
🟢 B. Tort
, 🔴 Explanation: A tort is a civil wrong other than a breach of contract,
encompassing intentional acts like battery or unintentional acts like negligence
committed against a patient or property.
Question 7
Which personal protective equipment measure is most critical when performing
a portable chest radiograph on a patient diagnosed with active pulmonary
tuberculosis?
A. Wearing sterile surgical gloves
B. Donning an N95 respirator mask before entry
C. Wearing a standard paper face mask
D. Requiring the patient to wear a lead apron
🟢 B. Donning an N95 respirator mask before entry
🔴 Explanation: Tuberculosis is an airborne infection requiring droplet nuclei
precautions, specifically mandating the use of a properly fitted N95 or higher-
level respirator mask for healthcare personnel entering the room.
Question 8
What does the radiation protection principle of ALARA stand for?
A. As Low As Reasonably Achievable
B. As Low As Radiation Allows
C. Always Limit Administrative Radiation Amounts
D. Annual Limit Allocation of Radiation Absorption
🟢 A. As Low As Reasonably Achievable
🔴 Explanation: ALARA is the fundamental guiding philosophy in radiation
protection, requiring technologists to use every reasonable effort to maintain
radiation exposures as far below occupational and public dose limits as
practical.
Question 9
A patient arrives in the imaging department with a physician's order for a lumbar
spine series, but the patient states they are pregnant. What is the technologist's
most appropriate immediate action?
A. Proceed with the examination using standard techniques.
B. Refuse to perform the exam and send the patient home.
C. Consult the ordering physician and the radiologist to verify pregnancy status
