Final answer:
The State Nurse Practice Act is the best source to consult for a nurse questioning an assigned duty concerning the scope of nursing practice, as it provides clear legal guidelines.
Step-by-step explanation:
If a nurse feels that an assigned duty is outside the scope of nursing practice, the best source to address this concern is the State Nurse Practice Act. This document provides the legal definition of a nurse's responsibilities and the boundaries within which a nurse must operate. The State Nurse Practice Act is specific to each state, giving clear guidelines about the duties permitted under a nurse's license.
While the ANA Code of Ethics provides the ethical framework for nursing practice and the Nurse's Bill of Rights advocates for the rights of nurses in the workplace, these do not offer legal scope of practice definitions. The QSEN Initiative focuses on quality and safety education for nurses but is not a regulatory document. If a duty seems outside of what is legally allowed, the State Nurse Practice Act is the authoritative source for scope of practice issues.
