The American Nurses Association (ANA) defines the Scope and Standards of Practice primarily to:

Choice A reason: The ANA Scope and Standards of Practice do not govern economic factors such as specific salary scales or mandatory staffing ratios. These are typically managed through facility policies, labor unions, collective bargaining agreements, or specific state-level legislative mandates regarding hospital staffing safety. Choice B reason: The ANA standards do not replace state Nurse Practice Acts (NPAs). NPAs are statutory laws enacted by state legislatures that provide the legal framework for nursing practice within that specific state. The ANA standards serve as a professional guide that complements, rather than overrides, these legal requirements. Choice C reason: Nursing is regulated at the state level rather than the federal level in the United States. While federal laws like HIPAA affect nursing, the professional standards of practice are established by professional organizations like the ANA to define clinical expectations and professional performance for all registered nurses. Choice D reason: The primary purpose of the ANA Scope and Standards of Practice is to provide a definitive description of the professional duties, responsibilities, and clinical expectations of nursing. It serves as a template for professional evaluation, quality improvement, and the definition of the nurse's role in the multidisciplinary team.
