Oriented X4

Person, place, time and situation. Some facilities only do 3X and some 4X...situation is the extra one.

Patient is aware of:

1. What their name is
2. Where they are
3. What time it is
4. What just happened/is happening

We just usually use x3

It's a good question... for some people, A&O x 3 would indicate a completely normal orientation, while for some A&O x 3 means they aren't oriented to event. Sometimes have to rely on context or, ideally, stop and clarify.

in NY it is x3 person place and time

You see EMTs/Paramedics use the A&O x 4 the most it is very helpful right after accidents...ie. Do you remember what just happened? A lot of people will remember everything else but will have a temporary loss of memory at the time of accident.
