Which of the following sequences of exams is correct for evaluating gastrointestinal issues?

The choice of gallbladder sonography, barium enema, and upper GI in this sequence is coherent with the clinical approach to evaluating gastrointestinal issues.

Starting with gallbladder sonography, this imaging is a non-invasive procedure commonly used to assess gallbladder-related conditions such as gallstones or inflammation. It provides immediate information about the gallbladder and surrounding structures, which can be critical in diagnosing acute abdominal pain.

Following gallbladder sonography with a barium enema is logical for further evaluation of the lower gastrointestinal tract, specifically the colon and rectum. This exam allows for visual exploration of these areas, helping to diagnose conditions such as colorectal cancer, inflammatory bowel disease, or other abnormalities in the colon.

The sequence concludes with an upper GI exam, which focuses on the esophagus, stomach, and the first part of the small intestine. This test typically evaluates issues such as ulcers, tumors, or reflux conditions. Placing it at the end of the sequence allows for a broader assessment after reviewing findings from the lower GI and gallbladder evaluations, particularly if there were indications of upper GI problems based on the prior tests.

This structured progression through the examinations not only follows a logical path in assessing potential issues but also maximizes
