ARRT Patient Care Practice Exam

What condition is considered a contraindication for barium studies?

1. GI perforation

2. Constipation

3. Diarrhea

4. Previous barium studies

The correct answer is: GI perforation

Barium studies involve the administration of barium sulfate to visualize the gastrointestinal tract during imaging procedures, such as X-rays. A significant contraindication for these studies is gastrointestinal perforation. When there is a perforation, the integrity of the GI tract is compromised, leading to the risk of barium leaking into the abdominal cavity. This can result in serious complications, including peritonitis, which is a life-threatening condition requiring immediate medical intervention. Therefore, performing a barium study in the presence of GI perforation can exacerbate the patient's condition and pose serious health risks. Constipation and diarrhea, while important considerations in terms of patient comfort and preparation for a barium study, do not pose immediate contraindications. Previous barium studies do not inhibit the ability to perform the exam, although they require careful consideration regarding patient history and timing. Thus, GI perforation stands out as a critical condition that must be addressed before any barium procedure is considered.
