QUESTIONS AND CORRECT ANSWERS
(VERIFIED ANSWERS) PLUS RATIONALES
2025|2026 Q&A | INSTANT DOWNLOAD PDF
1. Quick ARRT Exam Overview
• Purpose: Certifies radiologic technologists for safe and effective practice.
• Format: Computer-based, ~200 questions.
• Domains (approximate weight):
1. Patient Care (~33%)
2. Safety (radiation protection, procedures) (~22%)
3. Image Production (~25%)
4. Procedures (positioning, anatomy, protocols) (~20%)
2. Sample ARRT-Style Practice Questions
Patient Care
1. Before performing a radiographic exam, the technologist must verify:
• A. Patient’s blood type
• B. Correct patient and correct exam
• C. Patient’s insurance status
• D. Patient’s dietary intake
Answer: B. Correct patient and correct exam
Rationale: Patient identification and exam verification are key safety steps
before any radiographic procedure.

Safety
2. Which unit measures occupational radiation dose?
• A. Gray (Gy)
• B. Sievert (Sv)
• C. Becquerel (Bq)
• D. Coulomb/kg
Answer: B. Sievert (Sv)
Rationale: Sievert is the SI unit for equivalent dose, accounting for radiation
type and biological effect.
Image Production
3. Increasing kVp will primarily affect:
• A. Image sharpness
• B. Patient dose only
• C. Image contrast and beam penetration
• D. Focal spot size
Answer: C. Image contrast and beam penetration
Rationale: Higher kVp increases beam energy, decreasing contrast but
improving penetration.
Procedures
4. Which projection best demonstrates the intervertebral foramina of the
lumbar spine?
• A. AP projection
• B. Lateral projection

A+ Grade RADIOLOGIC TECHNOLOGIST – ARRT EXAM.pdf
• C. Oblique projection
• D. PA projection
Answer: C. Oblique projection
Rationale: Oblique lumbar spine images show intervertebral foramina
clearly.
Safety / Radiation Biology
5. What is the annual occupational radiation dose limit for radiation workers
in the U.S.?
• A. 10 mSv
• B. 50 mSv
• C. 150 mSv
• D. 500 mSv
Answer: B. 50 mSv
Rationale: The NCRP (National Council on Radiation Protection) sets the
annual occupational dose limit at 50 mSv.
6. What happens to wavelength when frequency increases?
• A. Wavelength increases
• B. Wavelength decreases
• C. Wavelength stays the same
• D. Wavelength becomes infinite
Answer: B. Wavelength decreases
Rationale: Wavelength and frequency are inversely related when
propagation speed is constant.

7. What is the most common cause of aliasing in Doppler ultrasound?
• A. Low frequency transducer
• B. PRF (pulse repetition frequency) too low
• C. Excessive attenuation
• D. High propagation speed
Answer: B. PRF (pulse repetition frequency) too low
Rationale: Aliasing occurs when Doppler shift frequency exceeds half the
PRF (Nyquist limit).
8. Which ultrasound mode displays motion of structures over time?
• A. B-mode
• B. M-mode
• C. Doppler mode
• D. 3D mode
Answer: B. M-mode
Rationale: M-mode records motion of structures along a single scan line
over time.
9. The beam width is primarily determined by:
• A. Frequency
• B. Focal depth
• C. Transducer aperture and focusing
• D. Pulse duration
Answer: C. Transducer aperture and focusing
Rationale: Beam width depends on aperture size and focusing; narrower
beams improve lateral resolution.
