This case will be used for two questions. Upon examination, your patient with TBI is not oriented and confabulates a story explaining his situation. Although you introduced yourself to him yesterday, he has no memory of this. Your examination of him progresses smoothly, although he attempts to brush his hair with your goniometer. When the nurse and an aide enter his room, which is now crowded and quite loud, he becomes angry and throws the goniometer. This patient is most likely functioning at which Rancho Level of Cognitive Functioning?
