CAMRT Radiography Practice Exam

Which routine best identifies a swallowed coin in a child?

1. Acute abdomen series

2. KUB and left lateral decubitus

3. Supine and erect KUB

4. KUB and lateral abdomen

The correct answer is: KUB and lateral abdomen

The routine that best identifies a swallowed coin in a child is to perform a KUB (Kidneys, Ureters, Bladder) and a lateral abdomen view. The KUB view provides a comprehensive assessment of the abdominal contents, allowing for visualization of the coin in the gastrointestinal tract, while the lateral view enhances the ability to locate the object more precisely, especially if it’s in the esophagus or at a specific level within the stomach or intestines. The lateral abdomen view is particularly critical because it can help differentiate the coin from surrounding structures, providing clearer evidence of its location and facilitating further management or intervention if needed. Thus, using both views together gives a thorough examination that is effective in identifying swallowed coins in pediatric patients.
