CAMRT Radiography Practice Exam

In which position should a patient be placed to demonstrate a possible hiatal hernia during a GI exam?

1. Supine position

2. Trendelenburg position

3. Left lateral position

4. Seated position

The correct answer is: Trendelenburg position

Placing a patient in the Trendelenburg position can effectively aid in the evaluation of a possible hiatal hernia during a gastrointestinal exam. This position involves having the patient recline on their back while the legs are elevated higher than the head. By adopting this posture, gravitational forces can help pull the abdominal contents upward, potentially making it easier to visualize any herniation of the stomach through the diaphragm on imaging studies. This position can enhance the contrast between the organs and the diaphragm and can promote the filling of the esophagus and stomach, allowing for a clearer assessment of any abnormalities. Given its efficacy in demonstrating the anatomical changes associated with a hiatal hernia, this is the preferred positioning for such assessments.
