(3) An individual who, by medical examination, is found to be incapacitated shall then be admitted or referred for treatment.  Transportation may be provided to an individual admitted or referred for treatment through the approved service program or the emergency medical service.

(4) The voluntarily admitted individual may leave at any time or may consent to remain as long as the health professional believes appropriate.

(5) If a voluntarily admitted individual is admitted to an approved service program or emergency medical service, the family, next of kin, or someone whom the individual designates, shall be notified as promptly as possible.  If an adult requests that there be no notification, the request shall be respected.
