A nurse is caring for a 17-year-old client who is experiencing a relapse of leukemia and is refusing treatment. The client's mother insists that the client receive treatment. Which of the following actions should the nurse take?

The correct answer is B: Notify the provider of the situation. As a nurse, it is crucial to uphold the client's autonomy and right to refuse treatment, especially considering the client is a minor. By notifying the provider, the nurse ensures that the healthcare team is aware of the situation and can explore ethical and legal implications. Administering treatment against the client's wishes without proper authorization is a violation of the client's rights. Offering antiemetics, administering sedatives, or initiating IV per parent's request without proper assessment and authorization can compromise the client's autonomy and wellbeing. It is essential to involve the provider to address the complex ethical and legal considerations in this scenario.
