Introduction
This assessment evaluates the knowledge and cognitive skills required for intelligent performance of tasks
typically performed by entry-level radiologic technologists. The exam consists of 200 multiple-choice questions
divided into two sections, with a balanced mix of foundational theory, applied professional knowledge,
regulatory compliance, ethics, and real-world clinical scenarios. Questions assess critical thinking and decision-
making abilities essential for safe patient care, radiation protection, image production, and proper radiographic
procedures. The multiple-choice and scenario-based structure emphasizes real-world application, ensuring
candidates can translate theoretical knowledge into competent clinical practice while adhering to professional
standards and legal requirements.
,SECTION ONE: QUESTIONS 1–100
Question 1
When explaining a radiographic procedure to a pediatric patient (age 6), which communication approach is
MOST appropriate?
A. Use complex medical terminology to ensure accuracy
B. Provide simple, age-appropriate explanations using analogies
C. Speak only to the parent and avoid addressing the child
D. Rush through the explanation to minimize the child's anxiety time
🟢 Correct answer
🔴 RATIONALE: Age-appropriate communication using simple language and analogies helps pediatric patients
understand procedures without causing fear. Complex terminology confuses children, speaking only to parents
ignores the patient, and rushing increases anxiety.
Question 2
Which SI unit correctly measures absorbed radiation dose to tissue?
A. Coulomb per kilogram (C/kg)
B. Gray (Gy)
C. Sievert (Sv)
D. Becquerel (Bq)
,🟢 Correct answer
🔴 RATIONALE: Gray (Gy) is the SI unit for absorbed dose. C/kg measures exposure, Sv measures dose
equivalent/effective dose, and Bq measures radiation activity.
Question 3
For a PA chest radiograph, what is the recommended source-to-image distance (SID)?
A. 40 inches (100 cm)
B. 56 inches (140 cm)
C. 72 inches (180 cm)
D. 96 inches (240 cm)
🟢 Correct answer
🔴 RATIONALE: 72 inches (180 cm) is the standard SID for PA chest radiographs to minimize magnification of
cardiac structures and improve image quality.
Question 4
Which positioning technique best demonstrates the ( الساقfemur) without rotation?
, A. AP femur with foot internally rotated 15°
B. AP femur with foot in neutral position
C. Lateral femur with knee flexed 90°
D. AP femur with foot externally rotated 30°
🟢 Correct answer
🔴 RATIONALE: The neutral foot position ensures proper alignment of the femur without internal or external
rotation, providing accurate anatomical visualization.
Question 5
A patient presents with creatinine level of 2.5 mg/dL prior to contrast-enhanced CT. What is the MOST
appropriate action?
A. Proceed with contrast administration as scheduled
B. Administer extra hydration and proceed with contrast
C. Consult the physician before administering contrast media
D. Use high-osmolar contrast to reduce renal risk
🟢 Correct answer
🔴 RATIONALE: Elevated creatinine (normal: 0.6-1.2 mg/dL) indicates potential renal impairment. Contrast
administration may worsen kidney function, so physician consultation is required before proceeding.
