A registered nurse (RN) is a nurse who has graduated or successfully passed a nursing program from a recognized nursing school and met the requirements outlined by a country, state, province or similar government-authorized licensing body to obtain a nursing license. An RN's scope of practice is determined by legislation, and is regulated by a professional body or council.
Palliative care is an interdisciplinary medical caregiving approach aimed at optimizing quality of life and mitigating suffering among people with serious, complex, and often terminal illnesses. Within the published literature, many definitions of palliative care exist. The World Health Organization (WHO) describes palliative care as
"an approach that improves the quality of life of patients and their families facing the problem associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial, and spiritual".
Pediatric nursing is part of the nursing profession, specifically revolving around the care of neonates and children up to adolescence. The word, pediatrics, comes from the Greek words 'paedia' (child) and 'iatrike' (physician). 'Paediatrics' is the British/Australian spelling, while 'pediatrics' is the American spelling.
Nurse education consists of the theoretical and practical training provided to nurses with the purpose to prepare them for their duties as nursing care professionals. This education is provided to student nurses by experienced nurses and other medical professionals who have qualified or experienced for educational tasks, traditionally in a type of professional school known as a nursing school or college of nursing. Most countries offer nurse education courses that can be relevant to general nursing or to specialized areas including mental health nursing, pediatric nursing, and post-operative nursing. Nurse education also provides post-qualification courses in specialist subjects within nursing.
A licensed practical nurse (LPN), in much of the United States and Canada, is a nurse who provides direct nursing care for people who are sick, injured, convalescent, or disabled. In the United States, LPNs work under the direction of physicians, mid-level practitioners, and may work under the direction of registered nurses depending on their jurisdiction.
A nurse practitioner (NP) is an advanced practice registered nurse and a type of mid-level practitioner. NPs are trained to assess patient needs, order and interpret diagnostic and laboratory tests, diagnose disease, prescribe medications and formulate treatment plans. NP training covers basic disease prevention, coordination of care, and health promotion.
An Associate of Science in Nursing (ASN) is a tertiary education nursing degree which typically takes 2–3 years to complete. In the United States, this type of degree is usually awarded by community colleges or similar nursing schools. Some four-year colleges also offer this degree. Students awarded an Associate of Science in Nursing are qualified to sit for the NCLEX-RN and apply for licensure as a Registered Nurse.
Nursing credentials and certifications are the various credentials and certifications that a person must have to practice nursing legally. Nurses' postnominal letters reflect their credentials—that is, their achievements in nursing education, licensure, certification, and fellowship. The letters usually appear in the following order:
Nursing in the United States is a professional health care occupation. It is the largest such occupation, employing millions of certified professionals. As of 2023, 3,175,390 registered nurses were employed, paid a median income of $86,070.
Critical care nursing is the field of nursing with a focus on the utmost care of the critically ill or unstable patients following extensive injury, surgery or life-threatening diseases. Critical care nurses can be found working in a wide variety of environments and specialties, such as general intensive care units, medical intensive care units, surgical intensive care units, trauma intensive care units, coronary care units, cardiothoracic intensive care units, burns unit, paediatrics and some trauma center emergency departments. These specialists generally take care of critically ill patients who require mechanical ventilation by way of endotracheal intubation and/or titratable vasoactive intravenous medications.
Emergency nursing is a specialty within the field of professional nursing focusing on the care of patients who require prompt medical attention to avoid long-term disability or death. In addition to addressing "true emergencies," emergency nurses increasingly care for people who are unwilling or unable to get primary medical care elsewhere and come to emergency departments for help. In fact, only a small percentage of emergency department (ED) patients have emergency conditions such as a stroke, heart attack or major trauma. Emergency nurses also tend to patients with acute alcohol and/or drug intoxication, psychiatric and behavioral problems and those who have been raped.
In the United States, a psychiatric-mental health nurse practitioner (PMHNP) is an advanced practice registered nurse trained to provide a wide range of mental health services to patients and families in a variety of settings. PMHNPs diagnose, conduct therapy, and prescribe medications for patients who have psychiatric disorders, medical organic brain disorders or substance abuse problems. They are licensed to provide emergency psychiatric services, psychosocial and physical assessments of their patients, treatment plans, and manage patient care. They may also serve as consultants or as educators for families and staff. The PMHNP has a focus on psychiatric diagnosis, including the differential diagnosis of medical disorders with psychiatric symptoms, and on medication treatment for psychiatric disorders.
Neonatal nursing is a sub-specialty of nursing care for newborn infants up to 28 days after birth. The term neonatal comes from neo, "new", and natal, "pertaining to birth or origin". Neonatal nursing requires a high degree of skill, dedication and emotional strength as they care for newborn infants with a range of problems. These problems vary between prematurity, birth defects, infection, cardiac malformations and surgical issues. Neonatal nurses are a vital part of the neonatal care team and are required to know basic newborn resuscitation, be able to control the newborn's temperature and know how to initiate cardiopulmonary and pulse oximetry monitoring. Most neonatal nurses care for infants from the time of birth until they are discharged from the hospital.
A family nurse practitioner (FNP) provides continuing and comprehensive healthcare for the individual and family across all ages, genders, diseases, and body systems. Primary care emphasizes the holistic nature of health and it is based on knowledge of the patient in the context of the family and the community, emphasizing disease prevention and health promotion.
A pediatric intensive care unit, usually abbreviated to PICU, is an area within a hospital specializing in the care of critically ill infants, children, teenagers, and young adults aged 0–21. A PICU is typically directed by one or more pediatric intensivists or PICU consultants and staffed by doctors, nurses, and respiratory therapists who are specially trained and experienced in pediatric intensive care. The unit may also have nurse practitioners, physician assistants, physiotherapists, social workers, child life specialists, and clerks on staff, although this varies widely depending on geographic location. The ratio of professionals to patients is generally higher than in other areas of the hospital, reflecting the acuity of PICU patients and the risk of life-threatening complications. Complex technology and equipment is often in use, particularly mechanical ventilators and patient monitoring systems. Consequently, PICUs have a larger operating budget than many other departments within the hospital.
Nurses in Canada practise in a wide variety of settings, with various levels of training and experience. They provide evidence-based care and educate their patients about health and disease.
A neonatal nurse practitioner (NNP) is an advanced practice registered nurse (APRN) with at least 2 years experience as a bedside registered nurse in a Level III NICU, who is prepared to practice across the continuum, providing primary, acute, chronic, and critical care to neonates, infants, and toddlers through age 2. Primarily working in neonatal intensive care unit (NICU) settings, NNPs select and perform clinically indicated advanced diagnostic and therapeutic invasive procedures. In the United States, a board certified neonatal nurse practitioner (NNP-BC) is an APRN who has acquired Graduate education at the master's or doctoral level and has a board certification in neonatology. The National Association of Neonatal Nurse Practitioners (NANNP) is the national association that represents neonatal nurse practitioners in the United States. Certification is governed by the National Certification Corporation for Obstetrics, Gynecologic and Neonatal Nursing Specialties (NCC).
An adult-gerontology nurse practitioner (AGNP) is a nurse practitioner that specializes in continuing and comprehensive healthcare for adults across the lifespan from adolescence to old age.
Nursing is the largest healthcare profession in the United States, with more than 3.1 million registered nurses. Between 2012 and 2022, employment for nurses is projected to grow by 19 percent, which is more than any other profession. Nurses make up the largest component of staff in hospitals but are also able to provide care in clinic settings, patient's homes, schools, nursing homes, public health agencies, and mental health centers. In addition, nurses can be found in the military, in industry, nursing education, and do health care research. Nurses in these various roles and settings can provide direct patient care and case management, but also develop and establish nursing practice and quality standards within complex healthcare systems. As each degree can provide a different level of care for patients and function in vastly different roles, it is important to differentiate between them. The levels of nursing degrees have different educational requirements, licensure, and credentialing that can vary state to state.
An acute care nurse practitioner (ACNP) is a registered nurse who has completed an accredited graduate-level educational program that prepares them as a nurse practitioner. This program includes supervised clinical practice to acquire advanced knowledge, skills, and abilities. This education and training qualifies them to independently: (1) perform comprehensive health assessments; (2) order and interpret the full spectrum of diagnostic tests and procedures; (3) use a differential diagnosis to reach a medical diagnosis; and (4) order, provide, and evaluate the outcomes of interventions. The purpose of the ACNP is to provide advanced nursing care across the continuum of health care services to meet the specialized physiologic and psychological needs of patients with acute, critical, and/or complex chronic health conditions. This care is continuous and comprehensive and may be provided in any setting where the patient may be found. The ACNP is a licensed independent practitioner and may autonomously provide care. Whenever appropriate, the ACNP considers formal consultation and/or collaboration involving patients, caregivers, nurses, physicians, and other members of the interprofessional team.
