When a prisoner is sent to the hospital, the symptoms shall be provided truthfully; the prisoner shall follow the treatment instructed and shall not ask the physician to add any text that is irrelevant to the illness. If the prisoner seeks any disposition or special treatment that is not required for the treatment, the physician shall refuse such request.
