What is the primary method for documenting contrast administration in an IR exam?

The primary method for documenting contrast administration in an interventional radiology (IR) exam is through the Begin or End Exam Navigators used by technologists. These navigators provide a structured framework within the Epic system that ensures all necessary aspects of the procedure, including contrast administration, are accurately recorded.

Using the Begin or End Exam Navigators allows technologists to input vital information in real-time, providing a clear, concise, and comprehensive log of the contrast used during the procedure. This documentation is essential not just for maintaining an accurate patient record but also for ensuring patient safety, as it helps healthcare providers track the type, amount, and timing of contrast administration.

In contrast to the other choices, which involve different aspects of patient care or documentation, the Begin or End Exam Navigators specifically cater to the technical execution of the imaging procedure and detail the contrast usage, making it the most appropriate method for this task.
