Formal exceptions to rulings or orders of the court are unnecessary; but for all purposes for which an exception has heretofore been necessary it is sufficient that a party, at the time the ruling or order of the court is made or sought, makes known to the court the action which the party desires the court to take or the party’s objection to the action of the court and the party’s grounds therefor if requested; and if a party has no opportunity to object to a ruling or order at the time it is made, the absence of an objection does not thereafter prejudice the party. With the consent of the court a party may object to an entire line of testimony, or to the entire testimony of a witness, or to testimony on a single subject matter, and if such objection shall be overruled, it shall not be necessary for the party to repeat his or her objection thereafter, but every part of such testimony thereafter introduced shall be deemed to have been duly objected to and the objection overruled.
