Peter, It's hard to say what the best solution is here without understanding all the context - but one approach which you could use is findAndModify. This will query for a single document and return it, and also apply an update to it.

You could use this to find a document to process and simultaneously modify a "status" field to mark it as being processed, so that other workers can recognize it as such and ignore it.

There is an example here that may be useful: http://docs.mongodb.org/manual/reference/command/findAndModify/
