A nurse is interviewing a client who was recently admitted. The client tells the nurse, "I have something to tell you, but you can't tell anyone else." Which of the following responses should the nurse make?

Introduction: Therapeutic communication requires establishing professional boundaries and maintaining transparency regarding the limits of confidentiality. Nurses must ensure the multidisciplinary team receives pertinent clinical data to maintain patient safety, especially concerning self-harm, suicidal ideation, or potential violence toward other individuals. A. This response is non-therapeutic because it offers false reassurance and establishes a pact of secrecy that violates professional nursing standards. Keeping secrets can compromise the safety of the client and others if the shared information involves harmful intent, ultimately hindering the effective delivery of psychiatric care. B. This is the most appropriate response as it maintains honesty and establishes clear boundaries. It informs the client that the nursing staff functions as part of a collaborative treatment team. This transparency prevents the client from feeling betrayed later if the information must be disclosed for safety reasons. C. This response is subjective and potentially paternalistic, as it suggests the nurse alone decides what information is valuable. While the nurse does exercise clinical judgment, the phrasing may cause the client to feel guarded or manipulated, rather than understanding the legal and ethical requirements of team-based communication. D. This choice gives the client total control over what is communicated to the healthcare provider. In a mental health setting, the nurse has a duty to report all clinically significant data. Allowing the client to "filter" the report could lead to the omission of critical diagnostic or safety-related information.
