Good luck!

A registered nurse ("RN"), is a health care professional responsible for implementing the practice of nursing through the use of the nursing process (in concert with other health care professionals). Registered nurses work as patient advocates for the care and recovery of the sick and maintenance of the healthy. In their work as advocates for the patient, RNs ensure that the patient receives appropriate and professional care. RNs use the nursing process to assess, plan, implement, and evaluate nursing care of the sick and injured.

The scope of practice of registered nurses is the extent to which an RN can practice and the limits of that practice. In the United States, these limits are determined by a set of laws known as the Nurse Practice Act of the state or territory in which an RN is licensed. Each state has its own laws, rules, and regulations governing nursing care. Usually the making of the rules and regulations is delegated to a state board of nursing, which performs the day-to-day administration of these rules, qualifies candidates for licensure, licenses nurses and nursing assistants, and makes decisions on nursing issues. The scope of practice for a registered nurse is wider than for a licensed practical or vocational nurse (LPN or LVN) because of the level and content of education as well as what the Nurse Practice Act says about the respective roles of each.

In the hospital setting, registered nurses are often assigned a supervisory role to oversee tasks performed by LPNs and unlicensed assistive personnel such as nursing assistants. However, the RN remains responsible for the safety and care of the patient.

RNs are not limited to employment as bedside nurses. Registered nurses are employed by physicians, attorneys, insurance companies, private industry, school districts, ambulatory surgery centers and fire departments, among others. Some registered nurses are independent consultants who work for themselves, while others work for large manufacturers or chemical companies.
