NursingNursing 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.
Nurse practitionerA 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. The scope of practice for a NP is defined by legal jurisdiction.
Medical prescriptionA prescription, often abbreviated or Rx, is a formal communication from a physician or other registered healthcare professional to a pharmacist, authorizing them to dispense a specific prescription drug for a specific patient. Historically, it was a physician's instruction to an apothecary listing the materials to be compounded into a treatmentthe symbol (a capital letter R, crossed to indicate abbreviation) comes from the first word of a medieval prescription, Latin (), that gave the list of the materials to be compounded.
Medicare Part DMedicare Part D, also called the Medicare prescription drug benefit, is an optional United States federal-government program to help Medicare beneficiaries pay for self-administered prescription drugs. Part D was enacted as part of the Medicare Modernization Act of 2003 and went into effect on January 1, 2006. Under the program, drug benefits are provided by private insurance plans that receive premiums from both enrollees and the government. Part D plans typically pay most of the cost for prescriptions filled by their enrollees.
Advanced practice nurseAn advanced practice nurse (APN) is a nurse with post-graduate education and training in nursing. Nurses practicing at this level may work in either a specialist or generalist capacity. APNs are prepared with advanced didactic and clinical education, knowledge, skills, and scope of practice in nursing. In the United States, the National Council of State Boards of Nursing along with other nursing authorities and organizations recommend the use of the term and acronym advanced practice registered nurse (APRN) as described in the Consensus Model for APRN Regulation, Licensure, Accreditation, Certification and Education.
Nursing managementNursing management consists of the performance of the leadership functions of governance and decision-making within organizations employing nurses. It includes processes common to all management like planning, organizing, staffing, directing and controlling. It is common for registered nurses to seek additional education to earn a Master of Science in Nursing or Doctor of Nursing Practice to prepare for leadership roles within nursing. Management positions increasingly require candidates to hold an advanced degree in nursing.
Gerontological nursingGerontological nursing is the specialty of nursing pertaining to older adults. Gerontological nurses work in collaboration with older adults, their families, and communities to support healthy aging, maximum functioning, and quality of life. The term gerontological nursing, which replaced the term geriatric nursing in the 1970s, is seen as being more consistent with the specialty's broader focus on health and wellness, in addition to illness. Gerontological nursing is important to meet the health needs of an aging population.
Physician assistantA Physician Assistant or Physician Associate (PA) is a type of healthcare professional. While these job titles are used internationally, there is significant variation in training and scope of practice from country to country, and sometimes between smaller jurisdictions such as states or provinces. Depending on location, PAs practice semi-autonomously under the supervision of a physician, or autonomously performing a subset of medical services classically provided by physicians.
Registered nurseA 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. Registered nurses are employed in a wide variety of professional settings, and often specialize in a field of practice.
Prescription drugA prescription drug (also prescription medication, prescription medicine or prescription-only medication) is a pharmaceutical drug that is permitted to be dispensed only to those with a medical prescription. In contrast, over-the-counter drugs can be obtained without a prescription. The reason for this difference in substance control is the potential scope of misuse, from drug abuse to practicing medicine without a license and without sufficient education. Different jurisdictions have different definitions of what constitutes a prescription drug.
