The prefix "postoperative" literally means "after surgery", indicating that it refers to events and procedures that occur after a surgery has been performed. The other options are incorrect because option A (before surgery) does not make sense in the context of the prefix as it would be known as "preoperative"; option C (during surgery) would be known as "intraoperative"; and option D (near surgery) does not accurately convey the timeframe of after a surgery has been completed. Therefore, option B is the most appropriate as it correctly reflects the meaning of the prefix "postoperative".
