In most jurisdictions, Good Samaritan laws only protect those that have had basic first aid training and are certified by the American Heart Association, American Red Cross, St. John Ambulance, American Safety and Health Institute or other health organization. In other jurisdictions, any rescuer is protected from liability, granted the responder acted rationally.

Yes. In states where these “Good Samaritan” laws are as you describe, you are protected as long as you render aid within the limits of your training/certification. However, rendering some sort of basic comfort and aid, even if it's just kneeling beside the victim and providing comforting words, is the least a normal, compassionate person would be expected to do under most circumstances.
