The correct answer to this question would be C: a levin tube is a double lumen nasogastric tube with an air vent. I don’t know what this definition applies to, but I do know that it is not a levin tube.
A levin tube is a thin, small tube with markings at the 18 inch and 24 inch marks, as well as other places. The levin tube also has only one lumen, and it’s small.
The rest of the answers on here are correct. The cantor tube has an inflatable bag. The Miller-Abbot tube is used to drain the small intestine, and so on. Since the question asks us to define which one is wrong, my work here is done.
