Public Health Nursing Careers

While there are many areas of public health nursing you can be a part of, here’s a look at a few paths in demand today.

Disaster Preparedness, Response and Recovery

According to the American Public Health Association (APHA), public health nurses are an important part of the National Preparedness Goal, which is part of the National Preparedness System. However, due to legal and ethical concerns, nurses who want to respond in catastrophic events should be aware of laws in their state and have the appropriate training.

There are four disaster stages in which public health nurses participate in:

  • Prevention
  • Preparedness
  • Response
  • Recovery

Each phase has different goals and needs. For instance, if you’re responding to a disaster, you may work at determining the needs of the community and triaging victims. On the other hand, you might find yourself working in the prevention stage developing plans to increase the public’s understanding of what to do during a disaster.

Army Public Health Nurse

Joining the nurse corps allows you to work directly with the military community and their families to improve their health and quality of life.

As a public health nurse in the army, your role will include:

  • Disseminate health information by working with local officials, the community and schools
  • Assess community needs
  • Develop public health plans and programs for military members and their families

Childhood Obesity

Childhood obesity has been in the news for some time but with the help of public health nurses, improvements have been made. You’ll work with community leaders, parents, schools and the government to promote better habits among children. Other tasks include:

  • Educating parents on dangers of obesity and ways they can help their children
  • Advocating for healthier school menus by working with nutritionists and faculty
  • Developing improvement plans based on assessments of a community
  • Working with local officials to build more parks and other areas for physical activity

Career Advancement

Most registered nurses (RN) begin their careers are staff nurses in hospitals or community health settings. With experience, good performance and continuing education, you can move on to more specialized settings and be promoted to management positions.

Increasingly, management-level nursing positions require a master’s degree. Because of the diverse work involved in public health nursing, students in a master’s-level public health nursing program will benefit from taking courses including biostatistics, environmental health, epidemiology, and behavioral sciences.

After you’ve gained two years of experience in public health nursing practice, you can become certified in your field. Although not required, certification can increase your chances of getting a job and receiving promotions.
