As a classmate and I decided , being a CNA is n't exactly enjoyable work , but it 's rewarding . I might have saved a guys life ! I noticed blood in his stool ( 'cause that 's about half of what CNAs do : wipe people 's asses ) which indicated internal bleeding . He had been feeling icky all day and when I told the LPN about the blood and she checked it out , she called for an ambulance to take him to the hospital .
