Most nurses recall the class in anatomy and physiology when we learned the great common memory aid, “On Old Olympus Towering Tops A Finn And German Viewed Some Hops” in an effort to learn the names of the 12 cranial nerves. For many of us, that moment was one of the last times we gave cranial nerves any thought. However, with diagnoses such as head injury and stroke continuing to rank highly on the morbidity and mortality charts, the ability of an emergency nurse to identify and monitor symptoms of neurologic dysfunction has become ever more critical.
