What information should a nurse provide a client undergoing an upper gastrointestinal series with fluoroscopy?

The correct information to provide to a client undergoing an upper gastrointestinal series with fluoroscopy involves the use of a contrast substance, typically barium, which is ingested (or sometimes administered rectally) to enhance visualization of the gastrointestinal tract during imaging. This substance allows the healthcare team to obtain clearer images of the esophagus, stomach, and duodenum, assisting in the diagnosis of conditions affecting these organs.

It is important to clarify that the test does involve the use of a contrast medium, but the formulation differs from traditional contrast dyes used in other imaging studies, which may be injected. As such, while the use of contrast is central to the test, the method of administration is through ingestion rather than injection. Understanding this aspect helps patients prepare mentally for the procedure.

The other choices focus on details that are either inaccurate or not directly relevant to the preparation protocol for this specific examination. Clients should be informed appropriately about how to prepare for the test, including necessary fasting instructions and what to expect during and after the procedure.
