Nursing
Professional nursing

The practice of nursing is based upon a social contract that delineates professional rights and responsibilities as well as accountability mechanisms. In almost all countries, nursing practice is defined and governed by law, and entrance to the profession is regulated at the national or state level.

The nursing community worldwide aims for professional nurses to ensure quality care, while maintaining their credentials, code of ethics, standards, and competencies, and continuing their education. Multiple educational paths lead to becoming a professional nurse; these vary by jurisdiction; all involve extensive study of nursing theory and practice as well as training in clinical skills.

Nurses provide care based on the individual's physical, emotional, psychological, intellectual, social, and spiritual needs. The profession combines physical science, social science, nursing theory, and technology.

Nurses typically hold one or more formal credentials. Roles and responsibilities follow the level of education. For example, in the United States, Licensed Practical Nurses (LPN) have less education than Registered Nurses (RN) and accordingly, a narrower scope of practice.
