Nurses utilize the Codes of Ethics established by the International Council of Nurses and the American Nurses Association in situations that require adherence to ethical principles, particularly in maintaining patient confidentiality and ensuring informed consent. Providing confidential genetic testing for a client is a prime example of this application, as it involves handling sensitive health information that is crucial for protecting the client's privacy and dignity.

In this scenario, the ethical guidelines help nurses navigate the complexities associated with genetic testing, including the potential implications for the client and their family. These codes emphasize the importance of respecting patient autonomy, ensuring informed choice, and maintaining confidentiality. This is vital in genetic testing, where the stakes can be particularly high due to potential disclosures of hereditary conditions and other personal health information.

While advocacy for curricula, ethical deliberations, and competency development are all important aspects of nursing practice, they do not directly involve the immediate application of ethical codes in the context of protecting patient rights and interests like the provision of confidential genetic testing does.
