            (3)      The attending physician determines that:

                  (i)      There is a substantial risk of death or immediate and serious harm to the patient; and

                  (ii)      With a reasonable degree of medical certainty, the life or health of the patient would be affected adversely by delaying treatment to obtain consent.
