For example, they assess trends to identify health risk factors, assign priorities for health-related interventions to enhance positive outcomes, design and implement health education activities and campaigns (DeMarco & Healey-Walsh, 2020). They deliver medical care when needed, including referring people to other related services. The public health nurses also provide information on local health services and programs, which are available to enhance aces to care and play advocacy roles to improve access to healthcare in underserved communities.In the 21st century, public health nurses face many challenges. For instance, there is a public health nursing workforce shortage, which leads to errors, dissatisfaction, burnouts, high mortality rates, and higher morbidity. There are generation workforce concerns due to increasing diversity, poor communication, disharmony, and a corresponding decrease in quality in patient care (DeMarco & Healey-Walsh, 2020). Besides, there is increasing clinical practice complexity and changing delivery systems since medicine is dynamic. In this manner, public health nurses have to engage in continuous education development to acquire new and modern skills and knowledge to meet the changing complex needs of the patients. The nurses are also urged to conduct new and better studies to improve the nursing profession through evidence-based practice.YirlenPublic health nurses play an integral role in promoting and upholding communities’ health care quality.

(2017), the United States Medicare admission is estimated to upsurge to 80 million, leading to increased healthcare demand in 2030 because of the aging baby boomers. Secondly, public healthcare nursing faces a shortage of physicians because of retirement and increasing healthcare demand.
