Two-point discrimination – can pt. recognize you are touching 2 points at a time 4. Extinction – pt. states whether your are touching L/R or both sides 5. Point location – touch pt. and they identify where they are being touched
65
What 4 things should you assess during a neurological re-check?
1. LOC (person, place, time) 2. motor function (facial movements, upper extremities, and lower extremities) 3. pupillary response (PERRLA) 4. vital signs (temp, pulse, resp.)
66
