A nurse is caring for a client who has borderline personality disorder. Which of the following defense mechanisms is commonly used by clients who have this disorder and has the potential to create division amongst the healthcare team?

A. Splitting: This mechanism is commonly seen in clients with borderline personality disorder. It involves viewing people or situations in black-and-white terms, categorizing them as all good or all bad. This can create division among the healthcare team, as team members may be viewed differently by the client depending on their current mood or interactions, leading to conflicts and confusion within the team. B. Regression: This defense mechanism involves reverting to behaviors of an earlier developmental stage. While it may occur in borderline personality disorder, it does not typically create division among healthcare team members like splitting does. C. Reaction formation: In this case, individuals behave in a way that is opposite to their true feelings. Although it can occur in various contexts, it is not as commonly associated with creating division within the healthcare team. D. Denial: This mechanism involves refusing to accept reality or facts. While present in borderline personality disorder, it does not specifically lead to division among team members in the same way.
