These 10 free ARRT(R) questions are organized by exam domain, so you can see how each part of the ARRT Radiography blueprint is tested. Reveal the answer and explanation under each question.
A radiographer performs a lumbar spine series without first asking the patient about the possibility of pregnancy. The patient is later determined to have been 8 weeks pregnant at the time of the examination. The radiographer's failure to follow the institutional pregnancy-screening protocol MOST directly constitutes which legal concept?
Correct answer: D - Negligence, because the radiographer failed to meet the accepted standard of care
Eight minutes after IV iodinated contrast administration for an IVU, a patient develops audible stridor, circumoral cyanosis, and begins clawing at their throat. The radiographer observes progressive laryngeal edema. What is the MOST appropriate immediate action?
Correct answer: B - Activate the emergency response system and prepare epinephrine 1:1,000 for IM administration
Before a lumbar spine series, a patient asks the radiographer: "Is there a radiation dose below which there is absolutely no cancer risk?" Which response is MOST consistent with the dose-response model used for radiation-induced cancer?
Correct answer: A - "No - the linear no-threshold model assumes any dose carries some level of increased risk."
A radiographer is standing 0.9 meters from the x-ray tube during a fluoroscopic procedure. The radiologist asks the radiographer to step closer and manually compress the patient's abdomen, reducing the radiographer's distance from the tube to 0.45 meters. Compared to the original position, how does the radiographer's exposure rate change?
Correct answer: C - It quadruples
A 34-year-old radiographer has worked in diagnostic radiology since age 24. According to NCRP recommendations, what is the maximum cumulative effective dose this individual should have received over their entire occupational career to date?
Correct answer: C - 340 mSv - based on the cumulative lifetime formula of 10 mSv multiplied by the worker's age in years
A DR hand radiograph produced at 55 kVp / 4 mAs / 100 cm SID / tabletop shows an exposure indicator within the facility's target range, but the radiologist flags the image for excessive quantum mottle. The radiographer wants to reduce mottle while maintaining the exposure indicator within the acceptable range. Which technique change BEST achieves both goals?
Correct answer: D - Increase mAs to 8 and reduce kVp to 48
A PA chest radiograph on an upright patient shows a homogeneous opacity in the right lower lobe that completely obliterates the right costophrenic angle. The physician wants to determine whether the opacity represents free-flowing pleural fluid or a fixed consolidation before ordering a CT. Which projection should the radiographer perform next, and how should the patient be positioned?
Correct answer: A - Left lateral decubitus - patient lies on the LEFT side with a horizontal beam directed across the right hemithorax
An orthopedic surgeon requests the intercondylar fossa projection that is performed with the patient PRONE, knee flexed to approximately 40-50 degrees, and a central ray angled 40-50 degrees caudad. Which projection does this describe?
Correct answer: B - Camp Coventry method
A biomedical engineer replaces a flat-panel DR detector following a hardware failure. Before the unit is returned to clinical use, which quality control procedure is MOST critical to perform to ensure accurate and uniform exposure indicators across the entire detector field?
Correct answer: C - Flat-field (flood-field) detector calibration to correct for non-uniform pixel sensitivity
A radiographer is performing an AP axial skull projection (Towne method) on a supine patient. The goal is to demonstrate the occipital bone, foramen magnum, and petrous ridges projected into the lower third of the orbits. What is the correct central ray angulation?
Correct answer: D - 30 degrees caudad to the orbitomeatal line (OML)
