ARRT Patient Care Practice Exam

In what order should the following examinations be performed: UGI, IVU, BE?

1. 3, 1, 2

2. 1, 3, 2

3. 2, 1, 3

4. 2, 3, 1

The correct answer is: 1, 3, 2

The correct order for performing these examinations—Upper Gastrointestinal (UGI), Intravenous Urography (IVU), and Barium Enema (BE)—is based on the preparation and contrast agents used for each procedure. Starting with the Upper Gastrointestinal series, which involves the ingestion of a contrast material (barium) to visualize the esophagus, stomach, and the first part of the small intestine, is often preferred first. Since this examination primarily requires the patient to consume the contrast, any residual effects or concerns from this exam can be managed before moving on to the others. Following the UGI, the Barium Enema is performed next. This exam focuses on visualizing the large intestine using a different application of barium. Conducting the BE after the UGI allows for efficient use of the contrast agent and minimizes the chances of bowel contamination affecting the results of the UGI. Lastly, the Intravenous Urography, which does not involve any barium ingestion or introduction to the digestive system, is positioned at the end. IVU utilizes iodinated contrast that is administered intravenously, and it is essential to complete it last to avoid any potential interference from the previous barium studies. This sequence helps to ensure
