Professional nursing practice mandates maintenance of therapeutic boundaries, prevention of dual relationships, protection of client confidentiality, and adherence to professional ethics. Boundary violations may impair clinical judgment, compromise trust, and expose sensitive health information, especially in digital communication contexts involving vulnerable adolescent populations. Rationale: A. Suggesting delayed communication via social media still implies willingness to engage outside professional boundaries. Boundary violation persists regardless of timing. Nurse-client relationships must remain strictly clinical. Social networking introduces risk of confidentiality breaches and role confusion, undermining professional integrity and therapeutic objectivity. B. Obtaining parental permission does not legitimize social media interaction with a client. Consent does not override professional standards. Digital communication outside clinical platforms risks confidentiality breaches. Ethical guidelines strictly prohibit forming personal or informal communication channels with clients regardless of age or guardian approval. C. Refusing interaction on social media appropriately maintains professional boundaries and prevents dual relationships. Nursing standards prohibit personal online engagement with clients to safeguard confidentiality and therapeutic integrity. This response reinforces ethical practice and protects both client welfare and professional accountability.
