Nursing practice is right granted by a state to protect those who need nursing care. The guidelines of the NPA and its rules provide safe parameters to work, as well as protect patients from unsafe nursing and unprofessional practice. Nursing practice information, advisories and guidelines are provided by the BRN to ensure continuous communication of competency standards to consumers, registered nurses, advanced practice nurses, employers, educators, and other regulators. As the scope of nursing practice changes and grows, this information also changes. The principles of nursing practice describe what everyone, from staff to patients, can expect from nursing.
