The laws that regulate nurses and nursing assistants are known as the Nurse Practice Act (Oregon Revised Statutes, Chapter 678.010-678.445). Any changes in the law must be made by the legislature. This law grants the OSBN authority to write administrative rules (Divisions 1-63) that further define the law. These rules have the effect of law and help define safe and competent practice. The OSBN can change administrative rules, and the public can provide comment and input during the rulemaking process.
