 It is the nurse's job to be aware of signs that professional boundaries may be crossed or have been crossed.Warning signs of boundary crossing that may lead to boundary violations include frequently thinking of a client in a personal way, keeping secrets with a specific client, favouring one client's care at the expense of another's and telling a client personal things about yourself in order to make an impression.Anything that could comprise the client's well-being if the relationship with a registered nurse is continued or discontinued can be considered a warning sign.
