Success
Test Bank: 28 Advanced MCQs with Rationales
1. Which of the following best describes the primary goal of radiologic
safety practices in diagnostic imaging?
A. Reducing equipment wear and tear
B. Increasing patient throughput
C. Protecting patients and personnel from unnecessary exposure
D. Ensuring image sharpness and detail
✅ Correct Answer: C
Rationale: The central principle of radiologic safety is minimizing
radiation exposure to patients and staff without compromising diagnostic
quality, following the ALARA principle (As Low As Reasonably
Achievable).
2. Wilhelm Conrad Roentgen is credited with which of the following
discoveries in 1895?
A. The gamma ray
B. The computed tomography scanner
C. The X-ray
D. The positron emission signal
✅ Correct Answer: C
Rationale: Roentgen discovered X-rays in 1895 while experimenting
with cathode rays, laying the foundation for modern diagnostic
radiology.
,3. In the context of student success, the term “emotional intelligence”
most accurately refers to the ability to:
A. Memorize large amounts of clinical content
B. Regulate one's emotions while empathizing with others
C. Score well on standardized licensing exams
D. Understand physiological reactions to radiation
✅ Correct Answer: B
Rationale: Emotional intelligence is critical in healthcare as it supports
self-awareness, self-regulation, and the ability to connect empathetically
with patients and colleagues.
4. Which radiation safety concept emphasizes using the minimum dose
necessary to achieve diagnostic quality images?
A. Inverse square law
B. Isodose calculation
C. ALARA principle
D. Photoelectric effect
✅ Correct Answer: C
Rationale: ALARA stands for “As Low As Reasonably Achievable”
and is a guiding safety principle in radiologic practice aimed at
minimizing radiation dose.
5. The accrediting body responsible for setting educational standards in
radiologic technology programs in the U.S. is:
A. ARRT
B. OSHA
C. JRCERT
D. HIPAA
, ✅ Correct Answer: C
Rationale: The Joint Review Committee on Education in Radiologic
Technology (JRCERT) accredits educational programs in radiologic
sciences, ensuring quality and compliance with national standards.
6. Which of the following is the most effective strategy for a student
technologist to manage clinical stress?
A. Avoiding emotionally intense cases
B. Studying only immediately before exams
C. Practicing mindfulness and time management
D. Working overtime to impress instructors
✅ Correct Answer: C
Rationale: Evidence-based strategies like mindfulness, sleep hygiene,
and structured time management are proven to support learning, reduce
stress, and improve resilience.
7. The inverse square law states that:
A. Radiation exposure increases with higher tube current
B. Doubling the distance from the source reduces intensity by half
C. Radiation intensity is inversely proportional to the square of the
distance
D. Exposure time has no effect on dose
✅ Correct Answer: C
Rationale: According to the inverse square law, intensity decreases with
the square of the distance from the source (I ∝ 1/d²), which is
foundational for positioning and shielding practices.
