The claim shall take into consideration the claimant's lost employment opportunities, lost lifestyle opportunities, and emotional distress experienced as a result of personally caring for the person with a disability .

The claim shall be in addition to any other claim, including without limitation a reasonable claim for nursing and other care. The claim shall be based upon the nature and extent of the person's disability and, at a minimum but subject to the extent of the assets available, shall be in the amounts set forth below:
