ARRT Nuclear Medicine Technology Examination Practice Test
Nuclear medicine technology applies radioactive tracers to evaluate organ function, tissue distribution, and physiologic processes. Practice material samples patient preparation and identification, radiopharmaceutical handling, planar imaging, SPECT and PET acquisition, and gamma-camera quality control. It also addresses patient care around procedures, including responses to injection-site symptoms and instructions that support tracer clearance.
Exam overview
About the ARRT Nuclear Medicine Technology Examination Exam
The work combines safe administration with technically sound image acquisition and interpretation support. Technologists verify patient identity, check preparation requirements, document radiopharmaceutical preparation times, and respond appropriately when a patient reports a possible injection-site complication. Understanding tracer distribution helps explain instructions such as drinking fluids and voiding after imaging, while uptake procedures may involve reference-standard or background measurements. Acquisition concepts include why SPECT cameras rotate around the patient and how PET detection differs from conventional single-photon imaging. Quality-control questions may distinguish intrinsic uniformity testing, performed without a collimator, from other camera checks. Clinical judgment also includes assessing whether a procedure is justified and deciding how to proceed when a patient has not followed fasting instructions.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
During a radiopharmaceutical administration, the patient reports pain and swelling at the injection site. What should the technologist do?
Show answer
Correct answer: BPain and swelling may indicate infiltration or another injection complication. The technologist should stop, assess and document the event, notify the appropriate clinical staff, and follow local procedures for evaluating the administration and its effect on the study.
A radiopharmaceutical kit is reconstituted, but the preparation has not yet been used. Why is the preparation time important to document?
Show answer
Correct answer: AReconstitution time is needed to track the preparation's age and apply the kit instructions and facility procedures for expiration, storage, and quality control. It does not replace dose assay or other required checks.
Why is a reference standard or background measurement sometimes obtained during a thyroid uptake study?
Show answer
Correct answer: AA background measurement can help account for radiation not attributable to the thyroid, while a reference standard supports comparison with the administered activity. The exact calculation and measurement setup depend on the instrument and local protocol.
A patient asks why they need to drink fluids and void frequently after a routine bone scan. Which explanation is most appropriate?
Show answer
Correct answer: AFor many bone-imaging protocols, hydration and frequent voiding promote urinary excretion of unbound tracer and can reduce bladder activity and patient radiation dose. These instructions should be adapted to the specific study and the patient's clinical condition.
A patient is scheduled for a study that requires fasting. The patient reports eating shortly before arrival. What should the technologist do?
Show answer
Correct answer: CRecent food intake may affect some studies, but the significance depends on the specific examination and protocol. The technologist should communicate the information to the supervising clinician and follow established instructions rather than making an independent change.
Which action best supports accurate identification of a patient before administering a radiopharmaceutical?
Show answer
Correct answer: AUsing two approved patient identifiers and matching them with the order helps prevent wrong-patient procedures. Room numbers and familiarity are not reliable substitutes.
In SPECT acquisition, what is the purpose of rotating the gamma camera around the patient?
Show answer
Correct answer: ASPECT gathers projection data from multiple angular views around the patient. Reconstruction of those views produces a three-dimensional distribution estimate; rotation itself does not eliminate attenuation.
How to use this practice test
The free question bank contains 50 published practice questions. Each session presents up to 20 questions selected at random, with results shown after the session. Use the questions to check recall of tracer handling, patient-care decisions, imaging principles, and equipment quality control; review missed answers against the underlying concept before trying another session.
Preparation tips
- For radiopharmaceutical scenarios, practice linking preparation-time documentation to the reliability and traceability of the administered dose.
- Compare planar, SPECT, and PET detection and acquisition principles, including camera rotation and coincidence-based PET detection.
- Review gamma-camera uniformity testing and distinguish intrinsic testing without a collimator from extrinsic testing with one.
- Work through patient-care decisions involving identity verification, fasting deviations, injection-site pain or swelling, and post-scan hydration and voiding instructions.
- For thyroid uptake questions, identify how reference-standard or background measurements contribute to interpreting uptake results.
