Radiologic Technologist Practice Exam

During a barium enema exam, in which direction should the enema tip be inserted initially?

1. Posterior while the patient is exhaling

2. Posterior while the patient is inhaling

3. Anterior while the patient is exhaling

4. Anterior while the patient is inhaling

The correct answer is: Anterior while the patient is exhaling

In the context of a barium enema procedure, the enema tip should be inserted anteriorly (toward the front of the body) while the patient is exhaling. This technique is employed to help ensure that the tip is properly positioned within the rectum, minimizing discomfort for the patient and reducing the risk of injury to the rectal wall. When the patient exhales, the diaphragm moves upward, creating a bit more space in the abdominal cavity and allowing for easier insertion of the enema tip. Inhaling, on the other hand, would expand the abdomen and can create tension, making it more difficult and potentially uncomfortable for the patient during the insertion process. Choosing this method not only enhances patient comfort but also aligns with proper technique to ensure adequate preparation for the imaging procedure, prioritizing safety and effectiveness.
