Explanation:
The most important phrase is 'the divorce was not final', This mean that at the point of accidents, Mrs. Jones still held the status as his wife and considered the next of kin that can talk in Mr. Jones behalf (unless He specifically mentioned otherwise to his lawyer).
Because of this, Mrs. Jones has the authority to disclose her husband record and determine the type of treatment that Mr. Jones can choose in case he is unable to do so by himself due to the accidents.
