The routine that is best suited for identifying a swallowed coin in a child is a KUB (Kidneys, Ureters, Bladder) combined with a lateral abdomen view. This approach effectively visualizes the anatomy and provides comprehensive information regarding the coin's position. The KUB view demonstrates the overall abdominal contents, allowing for the identification of the coin in the gastrointestinal tract, typically in the esophagus or stomach.

The additional lateral abdomen view is crucial because it can reveal the coin’s orientation and ensure it is not obscured by overlying structures. The lateral view can help differentiate between a coin lying flat, which may appear as a thin line on the KUB, and a coin oriented on its edge, which could indicate a different clinical significance.

The other options, while they may provide some relevant information, do not combine views as effectively as the KUB and lateral abdomen approach. An acute abdomen series typically includes several views to assess for potential acute abdominal conditions but may not focus on the specifics of an ingested foreign body. The KUB and left lateral decubitus or the supine and erect KUB sequences may not provide as clear a delineation of the object’s position and characteristics compared to the combination of KUB and lateral abdomen
