Only Atlantic species (Ginglymostoma cirratum) of 25 carpet shark species (family Orectolobidae). Yellow- or gray-brown, sometimes with dark spots, it may grow to over 13 ft (4 m) long. It may attack swimmers, especially when provoked, but is not related to the dangerous gray nurse (Odontaspis arenarius), a sand shark.

Health-care profession providing physical and emotional care to the sick and disabled and promoting health in all individuals through activities including research, health education, and patient consultation. Nursing gained recognition in the 19th century with the activities of Florence Nightingale. Many nurses have specialties (e.g., psychiatry, critical care). Nurse-practitioners, clinical nurse specialists, nurse-anesthetists, and nurse-midwives undertake tasks traditionally performed by physicians. Nursing degrees go as high as the doctorate, and staff positions include administration. In addition to health-care settings, nurses practice in schools, the military, industry, and private homes. Community (public health) nurses educate the public on topics such as nutrition and disease prevention.

A nurse is responsible—along with other health care professionals—for the treatment, safety, and recovery of acutely or chronically ill/injured people, health maintenance of the healthy, and treatment of life-threatening emergencies in a wide range of health care settings. Nurses may also be involved in medical and nursing research and perform a wide range of non-clinical functions necessary to the delivery of health care. Nurses also provide care at birth and death. There is currently a shortage of nurses in the United States and a number of other developed countries.
The nursing career structure varies throughout the world. Typically there are several distinct levels of nursing practitioner distinguished by scope of practice. The major distinction is between task-based nursing and professional nursing. Nurses throughout the world are increasingly employed as registered nurses, advanced practice nurses, clinical nurse specialists and nurse practitioners. At the top of the educational ladder is the doctoral-prepared nurse. Nurses may gain a PhD or another doctoral degree, specializing in research, clinical nursing, and so forth. These nurses practice nursing, teach nursing, and carry out nursing research. As the science and art of nursing has advanced, so has the demand for doctoral-prepared nurses.
In various parts of the world, the educational background for nurses varies widely. In some parts of eastern Europe, nurses are high school graduates with twelve to eighteen months of training. In contrast, Chile requires any registered nurse to have at least a bachelor's degree.
Nurses are the largest group of providers in the health care system--there are over two million registered nurses in the United States of America (U.S.) alone, comprising about 13% of the fifteen million workers in the health care and social assistance category tracked by the U.S. Department of Labor.
Nursing is one of the most female-dominated occupations, but the number of males entering the profession is increasing. For example, in 2000 only 5.4% of registered nurses in the U.S. were male, however, that percentage represents a 226% increase over the previous two decades. In 2007, internationally, 10.7% of registered nurses and 10.4% of licensed practical nurses were male. Although the rise in the number of males entering and working in the nursing profession is an ongoing trend, females continue to predominate in nursing, as well as in the health care sector as a whole.
Governments regulate the profession of nursing to protect the public.
Examples include:
Australia has a long tradition of post-basic courses, usually of a six month (minor) or twelve month (major) duration, which included midwifery, maternal and child welfare, psychiatric, peri-operative ("theatre nursing"), intensive care, and coronary care in later years, as well as a myriad of other courses. They are now provided by the university sector as postgraduate diplomas or post graduate certificates, depending on the length and complexity.
Enrolled nurses are trained in the "technical and further education" (TAFE) sector of approximately twelve months duration. In some states, this length has been increased to 18 months to result in diploma level qualification rather than certificate 4. All Enrolled nurse training courses now include a module that permits enrolled nurses to dispense oral, topical, enteral medications, and intramuscular and subcutaneous injections. In some areas of Australia NSW in particular Enrolled nurses are also allowed to administer intravenous medications via a peripheral cannula up to a schedule 4d.
Types of nurses
In all states other than Victoria, nurses fall into the following major categories:
Professional titles
The professional courtesy title "sister" has fallen into disuse and disapproval, even though it was formerly used by both male and female registered general nurses. The title "nurse" was used when addressing enrolled nurses. The term "matron" is inadvisable.
In keeping with the relaxed attitude to formalities in Australia, most nurses are happy to be addressed by their first name and describe themselves either as "an RN" or "an EN". In Victoria, an enrolled nurse will commonly describe themselves as a "Div. 2".
In some instances, it could be argued that this is as a natural professional evolution and recognition of the outstanding clinical expertise some nurses have attained over the course of their careers in areas such as wound management.
All registered nurses and nurse practitioners in the province of Alberta are expected to maintain their clinical competence in order receive an annual practice permit from the College and Association of Registered Nurses of Alberta which also sets standards for scope of practice and provides practice support.
Some postgraduate nursing specialities include medical, pediatric, obstetric, surgical and community health nursing which are offered by a large number of colleges and universities throughout India. Some institutes such as the National Institute of Mental Health and Neurological Sciences (NIMHANS) offer specialization in psychiatric nursing, neurosurgical nursing.
The nursing staff at institutes and hospitals are segregated into teaching and clinical divisions. In the clinical division, the nurses' stages are- ward nurse, nursing superintendent grade 3, nursing superintendent grade 2, and nursing superintendent grade 1. And in the teaching section they are called nursing tutor grade 2 and grade 1.
There are seven divisions of the register; general, psychiatric, children's, intellectual disability, midwifery, public health and tutor.
Significant developments have occurred in post registration nurse education with a variety of programs available to nurses to support their practice and develop their career.
Similarly the NCNZ caused minor controversy when they gave the title nurse practitioner, thus preventing those with the title from using it. As a nurse practitioner, the nurse must undertake an approved course of study and present a portfolio of evidence to NCNZ for approval. There are now approximately 20 NP's in New Zealand with a smaller number of granted prescribing rights.
A Professional Regulatory Nursing Board implements and enforces the Nursing Act. The board is composed of a chairperson and six additional members, all of whom are nurses with at least a master's degree and ten years of nursing experience. The board inspects nursing schools, conducts licensure examinations, issues and monitors certificates of licensure, promulgates a code of ethics, participates in recognizing nursing specialty organizations, and prescribes guidelines and regulations governing the profession under the Nursing Act.
Subjects studied in the first year include:
The second year includes study of sciences fundamental to basic nursing and, depending upon the area for which the nursing school has been approved, one of the following subjects:
Since the 1990s, UK nurses are educated to diploma, bachelor's and even undergraduate master's degree levels. There are also post-graduate courses for graduates with a degree in a health related subject. They undertake their training at universities and in placements in healthcare services. The student will train in adult, child, mental health, or learning disabilities branch.
The Nursing and Midwifery Council in the UK is the regulatory body for nurses, midwives, and specialist practitioners. It maintains a register that is split into three parts:
In addition to this, there are two levels of nurse: first-level nurses trained for three or four years (RGN, RMN, RSCN, RNMH, RNchild, RNadult, RNmental health, RN Learning Disability) whereas second-level nurses are the state enrolled nurses (SENs) who trained for two years. The SEN training has been phased out, with many SENs retiring or converting to level one through further study.
Registered Nurses are able to undertake advanced practice training, commonly at advanced degree level to become specialist nurses in various fields, such as Emergency Nurse Practitioner. These nurses will have obtained, in addition to the basic registration with the NMC, an advanced recordable qualification.
Many nurses are members of trade unions, which represent them both individually and as a profession. The two main unions are UNISON and the Royal College of Nursing.
Prior to the creation of the new three-part register on August 1, 2004, nurses and midwives were divided into a part of the register they held a qualification in. This may be now described as a 'sub-part' of the nursing register. All newly qualified nurses register in 'sub-part' 12, 13, 14 or 15, showing their branch qualification. However, nurses still practicing and holding qualifications in 'sub-parts' 1-9 are registered as such.
There are approximately 689,000 nurses and midwives on the NMC's register, including those not practicing within the UK who have maintained their registration. Approximately 12% of registrants are male, and this is increasing. As of August 2005, the NMC register split into three parts: nurses, midwives, and specialist community public health nurses. There are 'sub-parts' that the nurse or midwife is registered to practice in.
There are various other higher managerial and specialist nurse roles; however these are less well defined on a national scale and vary from country-to-country.
An academic course of study at any level typically includes such topics as anatomy and physiology, ethics, psychology, nursing theory and legal issues. Additionally, extensive training in nursing practice is required.
All U.S. states and territories require graduation from an accredited nursing program and successful completion of the NCLEX-RN to obtain state licensure as an RN.
