The demand for personnel in the healthcare industry is increasing. The United States Bureau of Labor Statistics (BLS) projects that employment in healthcare occupations will expand by 16% between the years 2020 and 2030, which is much faster than the average growth projected for all other occupations.

Registered nurses, often known as RNs, are one of the types of healthcare professionals that are in high demand to care for an aging population. They are extremely sought after.


A healthcare provider is considered to be a registered nurse if they have successfully completed a nursing education program and is in possession of a valid nursing license. The main thing that makes registered nurses different from each other is where they choose to specialize.

Still, nurses can show potential employers that they are trained in a certain field by taking nurse education courses and getting credentials in those fields.


Different types of registered nurses fall into different categories according to the fields in which they specialize. The following is a list of some of the several types of registered nurses that are available in the United States:

Critical Care Nurse / ICU Nurse

Nurses who specialize in critical care work in intensive care units (ICUs) and critical care units (CCUs). Critical care nurses are sometimes referred to as intensive care unit (ICU) nurses, and vice versa. They are experts in providing care to patients who are hospitalized for serious diseases and require supervision 24 hours a day, seven days a week. The AACN is also in charge of making sure that nurses who work in intensive care units and critical care units have the right certifications.

Public Health Nurse

Nurses who work in the field of public health may find employment with government agencies, nonprofit groups, and other types of organizations that promote public health by providing educational opportunities and screenings. In contrast to registered nurses who work in private practices, those who work in public health are primarily concerned with the treatment of entire communities. The Certification in Public Health exams are given by the National Board of Public Health Examiners and can be taken by registered nurses who have a minimum of a bachelor’s degree and five years of relevant work experience in the field of public health.

Medical-Surgical Nurse

The majority of the time, medical-surgical nurses will be found working in hospital settings, where they will manage multiple patients on a daily basis, often between five and seven. Certifications for these nurses are given out by the Medical-Surgical Nurse Certification Board (MSNCB) and the American Nurses Credentialing Center (ANCC).

Addiction Nurse

RNs who specialize in addiction are sometimes referred to as substance abuse nurses. They may have chosen this line of work because they or a loved one has struggled with addiction to alcohol, or other substances. Alternatively, they may have witnessed someone they care about struggling with addiction. Recovery centers, hospitals, and outpatient care facilities are all common places of employment for addiction nurses. The International Nurses Society on Addictions (IntNSA) is in charge of giving nurses who work in the field of addictions certifications.

Occupational Health Nurse

An occupational health nurse will most often be found working in a clinical environment. However, they may also be employed full-time as nurses by large corporations. A large manufacturing corporation, for instance, would hire an occupational health nurse to help prevent injuries, manage workplace health issues, and administer workers’ compensation and family medical leave. These are all important aspects of workplace safety and health. The American Board for Occupational Health Nurses (ABOHN) has a program that lets people get certified.

Neonatal Nurse

A premature newborn, an infant who was born with a life-threatening or persistent condition, or an infant who was born before their due date are the focus of a neonatal nurse’s care. They might work in a critical care unit, intensive care unit, neonatal intensive care unit (NICU; pronounced “nick-you”), trauma unit, or some other type of medical facility. The AACN is in charge of the certification process for these registered nurses.

Cardiovascular Nurse

Cardiovascular Nurse Cardiovascular nurses are employed in healthcare facilities such as hospitals, coronary care units (CCUs), and physician practices to provide medical attention to patients who suffer from heart disease. The American Association of Critical-Care Nurses is the organization in charge of certifying nurses who work in the cardiovascular field (AACN).

Gastroenterology Nurse

Nurses who specialize in the field of gastroenterology provide assistance to patients who suffer from gastrointestinal ailments that affect the stomach and digestive tract. They could offer assistance to physicians while they are performing endoscopies and colonoscopies. The American Board of Certification for Gastroenterology Nurses (ABCGN) is the group in charge of certifying nurses who work in gastroenterology.
