Final answer:
The nurse in this scenario is acting as an advocate, legal overseer, and ethical caretaker by documenting, copying, and communicating the client's advance directive that stipulates not to resuscitate and ensuring the client's wishes are respected.
Step-by-step explanation:
The nursing role demonstrated by the nurse when a client admits to the telemetry floor with an advance directive not to be resuscitated is multifaceted. Firstly, the nurse acts as an advocate, ensuring that the client's wishes are understood and respected. This involves accurately documenting the existence of the advance directive in the client's electronic chart, making a copy of the document, and communicating the client's wishes to the physician promptly. Additionally, the nurse fulfills a legal responsibility role by ensuring that the advance directive is recognized and adhered to as a legal document. Lastly, the nurse plays an essential part in the ethical aspects of care, respecting the client's autonomy and right to make decisions regarding their own end-of-life care.
