This learning activity examines the foundations of healthy boundary-setting in nursing practice, exploring the distinction between personal and professional boundaries, the workplace dynamics that most commonly erode them, and evidence-based strategies for establishing and communicating limits that protect both clinician well-being and patient safety. Drawing on current nursing research and professional guidelines from the ANA and NCSBN, the activity guides nurses through the development of a personalized boundary action plan suited to their clinical setting, communication style, and individual vulnerabilities.
