Achim's suggestion is probably better because it will trigger for only one frame, which sound like what you're after.
Another option would be to connect the output of a random patch to a queue. You can then use a structure index patch to send a single value to the sprite, from the result of the queue. By stepping through various indices one can trigger the random values that have been stored in the queue.
