When scheduling radiographic examinations, which statement is true about barium studies?

• A. Schedule first
• B. Schedule in the afternoon
• C. Schedule last
• D. Schedule a scout CT scan first

Answer: (C)

Scheduling barium studies last takes into account the practical need to thoroughly clean and disinfect the room after a potentially messy GI exam. Barium contrast can coat the walls and equipment and may leave residue in drains, so having it at the end of the day minimizes disruption to other patients and reduces cross-contamination risk. It also allows the room to be reset and prepared for the next day without delaying other procedures. Placing it earlier in the day would require cleaning between patients or keeping the room idle, which is inefficient and increases the chance of mix-ups or delays. The option about a scout CT scan is unrelated to the management of a GI contrast study.
