I'm a new RN, and new on a neuro trauma ICU. It is very important that I understand assessment descriptions. My last pt. was an SAH/SDH whose only response was localization to deep (and I mean deep) painful stimuli. No spontaneous movement and follows commands x0. 8 on the GCS. I described her in my assessment as "obtunded". My preceptor corrected me and pointed out that she was "lethargic". Lethargic in my mind describes someone who is drowsy but arousable. I think I can describe myself as lethargic at times. Can you experienced nurses shed some light on this assessment paramater so that I might better understand? Would love some insight on this.
