Without knowing the context, I can't necessarily give you the best
answer.  There are several possibilities; you might check out
continuations.

The question does come to mind, though, of why you are using do.  It's
part of Scheme, true, but I don't think that using it is a particularly
Scheme-like solution.  There may be other ways to express the same
function that don't use do, in which case your `early exit problem' will
likely take care of itself.  Again, though, without knowing context,
it's a little hard to be specific.

HTH,
