Sample Questions

Question 1
Within the radiologist-led team, what is the defining scope limitation for a Registered Radiologist Assistant (R.R.A.) performing advanced procedures?
The R.R.A. may provide initial observations but cannot render the final, official interpretation of imaging studies
The R.R.A. may render final interpretations on plain radiographs but not on cross-sectional imaging
The R.R.A. practices fully independently once certified by ARRT
The R.R.A. may only perform procedures on patients under age 18 under radiologist supervision
Question 2
A 68-year-old patient scheduled for a fluoroscopic esophagram has a serum creatinine of 2.8 mg/dL and an eGFR of 24 mL/min/1.73 m². The study will use oral barium sulfate only. Based on the ACR Manual on Contrast Media, what is the correct action?
Proceed with the barium esophagram; renal function is not a contraindication to oral barium
Cancel the study because the eGFR is below 30
Administer IV normal saline at 100 mL/hr for 12 hours before the study
Substitute iodinated water-soluble contrast (Gastrografin) for the barium
Question 3
A patient develops severe bronchospasm and hypotension 2 minutes after IV iodinated contrast injection during a fluoroscopy-guided procedure. What is the first-line pharmacologic treatment according to the ACR Manual on Contrast Media?
Intramuscular epinephrine 0.3 mg (0.3 mL of 1:1,000) in the lateral thigh
IV diphenhydramine 50 mg
IV hydrocortisone 200 mg
Sublingual nitroglycerin 0.4 mg
Question 4
A patient with a documented prior moderate reaction to iodinated contrast requires a fluoroscopy-guided procedure that cannot be performed without iodinated contrast. Which ACR premedication regimen is most appropriate for an elective procedure?
Prednisone 50 mg PO at 13, 7, and 1 hour before contrast, plus diphenhydramine 50 mg IV/PO/IM 1 hour before contrast
Prednisone 10 mg PO 30 minutes before contrast only
Methylprednisolone 1 g IV immediately before contrast
Diphenhydramine 25 mg PO 15 minutes before contrast only
Question 5
