Many times people don't understand what they do, or what they should do simply because they don't have the knowledge. Long before we, as a nation, realized that smoking was bad for us, many people smoked. Through knowledge they concluded that smoking is bad, why and how to quit and that best practices would never have started. Through education, nurses can bring vital health and prevention information to the community, family and individual. In this way, the nurse can increase awareness of dangers, risks and avoidances for the community or family. Teen pregnancy, sexually transmitted diseases, suicide, bullying, diabetes, obesity and smoking are just some of the problems these nurses face. The home educator works on a smaller scale with individuals and families on issues such as living with chronic illnesses and preventing comorbidities. They provide education to the family on how to manage behaviors and other medical problems. By providing the community, family and individual with the knowledge and skills needed to prevent and manage health problems, everyone can be healthier through good decisions, prevention and timely interventions..
