brain injury impulsivness

We try to keep the patient close to the nurse's station, use bed alarms and family to sit with the patient. We are unable to have sitters in the critical care area so that is not an option for us. Sometimes I have seen nurses place signs around the room reminding the patient not to get up, to use the call light and wait for help. Just a few ideas, sometimes there is nothing you can do but use a restraint vest for the patient's safety.
