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 problems 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". In the past, palliative care was a disease specific approach, but today the WHO takes a broader patient-centered approach that suggests that the principles of palliative care should be applied as early as possible to any chronic and ultimately fatal illness. This shift was important because if a disease-oriented approach is followed, the needs and preferences of the patient are not fully met and aspects of care, such as pain, quality of life, and social support, as well as spiritual and emotional needs, fail to be addressed. Rather, a patient-centered model prioritizes relief of suffering and tailors care to increase the quality of life for terminally ill patients.
Primary care is the day-to-day healthcare given by a health care provider. Typically this provider acts as the first contact and principal point of continuing care for patients within a healthcare system, and coordinates other specialist care that the patient may need. Patients commonly receive primary care from professionals such as a primary care physician, a physician assistant, a physical therapist, or a nurse practitioner. In some localities, such a professional may be a registered nurse, a pharmacist, a clinical officer, or an Ayurvedic or other traditional medicine professional. Depending on the nature of the health condition, patients may then be referred for secondary or tertiary care.
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. 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-operatory nursing. Courses leading to autonomous registration as a nurse typically last four years. Nurse education also provides post-qualification courses in specialist subjects within nursing.
Psychiatric nursing or mental health nursing is the appointed position of a nurse that specialises in mental health, and cares for people of all ages experiencing mental illnesses or distress. These include: neurodevelopmental disorders, schizophrenia, schizoaffective disorder, mood disorders, addiction, anxiety disorders, personality disorders, eating disorders, suicidal thoughts, psychosis, paranoia, and self-harm.
A licensed practical nurse (LPN), in much of the United States and Canada, is a nurse who cares 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, formulate and prescribe medications and treatment plans. NP training covers basic disease prevention, coordination of care, and health promotion, but does not provide the depth of expertise needed to recognize more complex conditions.
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:
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.
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 assessment 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.
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.
Nursing is a profession within the healthcare sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health and quality of life. Nurses may be differentiated from other healthcare providers by their approach to patient care, training, and scope of practice. Nurses practice in many specialties with differing levels of prescription authority. Nurses comprise the largest component of most healthcare environments; but there is evidence of international shortages of qualified nurses. Nurses collaborate with other healthcare providers such as physicians, nurse practitioners, physical therapists, and psychologists. There is a distinction between nurses and nurse practitioners; in the U.S., the latter are nurses with a graduate degree in advanced practice nursing, and are permitted to prescribe medications unlike the former. They practice independently in a variety of settings in more than half of the United States. Since the postwar period, nurse education has undergone a process of diversification towards advanced and specialized credentials, and many of the traditional regulations and provider roles are changing.
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.
Perioperative nursing is a nursing specialty that works with patients who are having operative or other invasive procedures. Perioperative nurses work closely with surgeons, anaesthesiologists, nurse anaesthetists, surgical technologists, and nurse practitioners. They perform preoperative, intraoperative, and postoperative care primarily in the operating theatre.
Pediatric psychology is a multidisciplinary field of both scientific research and clinical practice which attempts to address the psychological aspects of illness, injury, and the promotion of health behaviors in children, adolescents, and families in a pediatric health setting. Psychological issues are addressed in a developmental framework and emphasize the dynamic relationships which exist between children, their families, and the health delivery system as a whole.
Loretta C. Ford is an American nurse and the co-founder of the first nurse practitioner program. Along with pediatrician Henry Silver, Ford started the pediatric nurse practitioner program at the University of Colorado in 1965. In 1972, Ford joined the University of Rochester as founding dean of the nursing school.
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.
