A nurse is assisting in the care of a client who has schizophrenia and is being prescribed a new antipsychotic medication. The client's parent asks the nurse not to discuss the medication side effects with the client. Which of the following ethical principles does this request violate?

Rationale: A. Veracity: Veracity refers to the obligation to tell the truth and provide accurate information. While withholding information could also violate this principle, the core issue in this scenario centers more on the client's right to make informed decisions rather than truth-telling alone. B. Fidelity: Fidelity involves keeping promises and maintaining trust in the nurse-client relationship. While failing to inform the client may strain trust, the request from the parent specifically violates the client's right to participate in decisions about their care. C. Autonomy: Autonomy is the right of individuals to make informed decisions about their own healthcare. Withholding information about medication side effects directly interferes with the client’s ability to provide informed consent, violating this fundamental ethical principle. D. Justice: Justice involves fairness and equality in the distribution of care and resources. This principle is not directly implicated in the scenario, as the issue is not about fairness but about the individual’s right to know and decide.
