Nurse licensure is the process by which a nurse obtains official permission to practice nursing in a specific state or country. This typically involves completing an accredited nursing program, passing a national licensing exam, and meeting any additional state requirements. Licensure ensures that nurses have the necessary knowledge and skills to provide safe and effective care to patients. Each state has its own nursing board, such as the Nurse Licensure Compact, which allows for easier practice across state lines. Maintaining licensure often requires ongoing education and renewal every few years, ensuring that nurses stay updated on best practices and advancements in healthcare.
