I am a Charge Nurse at a state inpatient psychiatric hospital. I work on an all female unit. We have 5 out of 15 patients that have a personality disorder diagnosis. One patient has narcissistic personality disorder. We recently had an LPN that had very loose boundaries with this patient and both began to target me. The LPN was eventually removed from the unit. The patient caught me off guard one day and punched me in the face as well as multiple times in the head. This patient has a behavior treatment plan for milieu disruptive behavior. I feel like her disruptive behavior escalates her and others into physically dangerous situations. I guess I have an idea of what milieu disruption is but this patient's behavior is sometimes very subtle. Can anyone give me examples of milieu disruptive behavior that you have experienced? I want to avoid another situation like this in the future not only for myself but for my staff.
