Nurse: Roles, Education, Specialties, and Practice

A nurse is a licensed health professional who provides clinical care, advocacy and health promotion across settings. This article outlines roles, training, specialties, workplaces and current issues.

Overview

A nurse is a trained health professional who assesses, treats and supports people who are sick, injured, recovering or at the end of life. Nurses work alongside doctors and other health workers to deliver care, to educate patients and families, and to promote health in communities. They combine clinical skills, observation, communication and ethical judgement to keep people safe and to improve outcomes.

Core responsibilities

Nursing duties vary with role and setting but commonly include: taking histories and vital signs, administering medications and treatments, monitoring progress, coordinating care, documenting findings, and educating patients about self-care. Nurses also provide emotional support, help families with bereavement, and act as patient advocates when decisions about care are needed.

Education, licensure and career pathways

Preparation for nursing differs by country and by level of practice. Programs range from certificate courses for entry-level practical nurses to university degrees for registered nurses and postgraduate education for advanced practice nurses. Licensure or registration by a regulatory authority is required in most places. Specialized roles—such as nurse practitioners, clinical nurse specialists, and nurse anesthetists—require additional training and certification.

Common specialties and workplaces

  • Acute care and medical-surgical units
  • Pediatrics, obstetrics and neonatal care
  • Surgical nursing and perioperative support, including roles that assist during surgery
  • Mental health and psychiatric nursing
  • Community, public health and school nursing
  • Geriatrics, palliative care and hospice services
  • Specialty clinics and outpatient care, including chronic disease education such as nutrition and disease management

History and development

Nursing evolved from unpaid caregiving and religious orders to a regulated profession with standardized education and science-based practice. Over time nursing adopted evidence-based methods, public health principles and expanded scopes of practice. Professional organizations and regulatory bodies now oversee standards, ethics and continuing education.

Importance and notable facts

Nurses make up a large proportion of the health workforce and are essential for safe, continuous care. Many health systems face nurse shortages, which has driven innovations such as travel nursing, team-based care, telehealth nursing and new roles to meet demand. Nurses increasingly lead quality improvement, infection control and health promotion efforts.

Contemporary nursing is shaped by technology (electronic records, telemedicine), a focus on patient safety and interprofessional collaboration. Common challenges include workforce sustainability, burnout, equitable access to education, and adapting to demographic changes such as aging populations. Ethical issues—like end-of-life decisions and resource allocation—remain central to practice.

Why nursing matters

Nurses provide hands-on care, interpret clinical changes, teach and comfort patients, and coordinate complex care plans. Their role stretches from bedside procedures to community health promotion and policy advocacy. For many patients, nurses are the primary point of contact and an enduring source of support throughout illness and recovery.

Job title

With the amendment of the Nursing Professions Act (Krankenpflegegesetz - KrPflG) of 1985 by resolution of the Bundestag in July 2003, the fourth Nursing Act of the Federal Republic of Germany came into force on 1 January 2004. This introduced a new, state-protected occupational title of health care worker and nurse for nurses trained after 1 January 2004, replacing the previous titles of nurse (which still originated from the old Christian orderly system) and nurse respectively. The legal protection of the former occupational titles was not abolished in the process; nurses trained under the third KrpflG, nurse practitioners, paediatric nurses and paediatric nurses may either continue to use the previous occupational title or use the new title.

The designation health care worker and nurse takes into account the changed professional self-image of nursing, emphasises the increasing independence and professionalisation of nursing and expresses an expanded range of tasks of professional nursing in the direction of health care and counselling. At the same time, this is intended to replace the "ideologically shaped" occupational title of nurse. With the gradual merging of nursing training with that in paediatric nursing and in geriatric nursing into a generalist nursing profession by the Nursing Professions Act, from 2020 the job title will be changed in part to nursing specialist. Primary qualified university graduates will use the new job title in conjunction with the academic degree (§§ 37 to 39 PflBG). A planned evaluation of future occupational choices is to decide on the initially existing continuation of the occupational titles of health and paediatric nurse and geriatric nurse.

Nursing job titles from other countries such as Switzerland (Diplomierter Pflegefachmann), France (Infirmier), Sweden (Sjuksköterska) or the Anglo-American area (Nurse) are usually based on academic training and cannot be fully equated with the German dual training to become a health and nursing professional. However, the degrees are usually mutually recognised. Under the EU Directive on the mutual recognition of professional qualifications, it is possible for German nurses to work within the EU and Switzerland.

However, the term "health care worker" has not yet become established in general linguistic usage. Traditionally, the terms nurse or nurse practitioner continue to be used, both by patients and even by the holders of the corresponding professional title.

Professional activity and fields of work

Alongside firefighters and doctors, health care workers and nurses ("Krankenschwestern") consistently rank among the three most trusted professions in Germany. 87% of the population expresses "very high" or "fairly high" trust in them.

Tasks and activities

Health care and nursing staff independently care for patients or persons in need of care of all age groups in inpatient facilities or in the context of outpatient care. These tasks in the field of basic care include supporting the patient in all everyday areas of life, for example in feeding, position support or personal hygiene. They accompany the seriously ill and dying, care for the deceased and serve as contact persons for relatives or other persons concerned. Nursing specialists plan nursing care within the framework of the nursing process, document its implementation and assess the success of the nursing measures applied. They carry out the necessary nursing service-related accounting, organisational and administrative work with the help of nursing assistant programmes, and monitor and order materials and medication stocks. They provide assistance and guidance to trainees, nursing assistants, interns and housekeeping staff.

Nursing staff are the link between doctors, therapists, relatives and patients, independently carry out medical orders within the framework of treatment care, prepare patients for therapeutic and diagnostic measures or carry out ordered necessary medical treatments. They assist doctors in carrying out therapeutic measures and provide psychological care for patients. They perform administrative and organisational tasks, coordinate appointments with other specialist departments and members of the therapeutic team, and take part in ward rounds and meetings. As part of patient observation, they determine and document the data required for therapy, such as blood pressure, pulse and temperature, and assess the patient's sleep patterns, breathing and behaviour.

Health care and nursing staff advise people in need of care and their relatives about care measures, health promotion and guide them to help themselves. They help with the procurement of necessary aids, participate in the communication with health insurance companies and the determination of the need for care by the Medical Service of the Health Insurance (MDK).

Suitability

With regard to the use of allergenic products, there should be no allergies to these products, especially if they are hardly or not replaceable by alternatives (e.g. certain hand disinfectants). Shift work with early, late, night shifts and weekend duties can cause additional physical stress. Training companies usually require a medical certificate of health. Working with sick and dying people is psychologically stressful. Some educational institutions also require a certificate of good conduct.

Work locations

Typical places of work are the specialist departments in general hospitals, specialist hospitals (for example for psychiatry), sanatoria and rehabilitation facilities, as well as in dialysis centres, nursing homes, homes for the elderly and hospices and with general or specialised outpatient nursing services. Some health and nursing professionals work on a self-employed basis as nursing consultants or are employed by the MDK (Medical Review Board), in advice centres, health offices, nursing care support centres and by health or nursing care insurance companies in advisory or expert opinion functions. In case management, they draw up assistance plans and link medical care, nursing care, social support and domestic help in transitional care. Some nursing specialists are employed as non-commissioned officers in the medical service of the German armed forces, work in shipping as ship's nurses or as civil servant health and nursing staff in correctional hospitals and wards in correctional institutions.
