Public health nurses work to improve the health of a community, rather than focusing on the individual. Programs they work on include traffic safety, obesity, climate change, chemical exposure prevention, emergency preparedness and more. Public health nursing organizations include the American Public Health Association (APHA). Public health nurses come from a wide range of specialties or can be credentialed in public health specifically. The American Nurses Credentialing Center (ANCC) maintains the Advanced Public Health Nursing (APHN-BC) credential program, formerly known as the Clinical Nurse Specialist in Public/Community Health credential. The U.S. Bureau of Labor Statistics predicts excellent, overall job growth for registered nurses. The median registered nurse salary is $62,450.
