Final answer:
As a nurse, it is important to respect the client's decision and collaborate with the healthcare team to ensure palliative care for a client with renal failure who wants to stop dialysis treatment.
Step-by-step explanation:
As a nurse, it is important to act as an advocate for the client and respect their decision-making autonomy. In this situation, the nurse should choose option C: Respect the client's decision and collaborate with the healthcare team to ensure the client receives adequate palliative care.
By respecting the client's decision, the nurse demonstrates respect for the client's autonomy and right to make decisions about their own healthcare. Collaborating with the healthcare team ensures that the client receives the best possible care, focusing on managing symptoms and providing comfort.
It is important not to try to convince the client to reconsider their decision (option A) as it goes against their autonomy. Similarly, informing the client's family without their consent (option B) violates the client's privacy and their right to self-determination. Documenting the client's decision but continuing to encourage alternative treatments (option D) disregards the client's wishes.
