Final answer:
The best legal safeguard for a graduate nurse is to have a valid license.
Step-by-step explanation:
The best legal safeguard for a graduate nurse starting a first nursing job would be to have a valid license. A valid license is essential for practicing nursing legally and ensures that the nurse meets all the necessary requirements and qualifications. Without a valid license, the nurse may face legal consequences and could jeopardize their career.
While competent practice is important for a nurse, having a valid license is the legal requirement and provides the necessary protection. A legal contract and following management policies are also important but do not serve as the best legal safeguard for a nurse.
