I always thought being a good samaritan was the right thing to do. Well one of my nurse instructors told us that if we see someone who needs CPR dying in the street we should not get involved. That if the person dies or lives and the people find out we are nurses, that familes can try to sue (for broken ribs or permanent damages, etc..). She says it's best to just call 911 and wait until medical personell arrive and let them deal with it. Is this true?
