Nurses are hands-on health professionals who provide focused and highly personalized care. A nurse practitioner (NP) is a mid-level practitioner and an advanced practice nurse (APN) with post-graduate education in nursing is prepared with advanced didactic and clinical education, knowledge, skills, and scope of practice in nursing. Licensed practical nurses take care of basic duties in settings such as hospitals, nursing homes, and long-term care facilities where nursing practice became a science, as well as an art. It is a complex ever-changing profession with ethics, standards, and best practices to improve your quality of care. Nurse educators for nursing are particularly conducted through implicit knowledge. Infection control nurses are concerned with preventing nosocomial or healthcare-associated infection, a practical sub-discipline of epidemiology.
