First the direct answer: you can’t.

Some more context: there’s usually ways to deal with this issue. There’s voir dire for example, where you can do a practice run of the questions and answers for a specific witness, or the party can profer (idk if it’s spelled correctly) the testimony, giving the judge a general idea of the direct or cross-examination.

This usually only happens if something goes wrong. It can be things like the lawyer overstepping a boundary by accident, but it’s very frowned upon and they can be admonished and sanctioned by the judge.

For why to do about the “can’t put the shit back in the horse”, usually the judge gives the jury an admonishment and maybe even a curative instruction right before deliberation, but best case scenario it’s been handled in advance and doesn’t even happen.
