Assessing to see if someone can pay attention to ACL 2 Low information will require positioning the person so you can see if they can hold their body posture upright against gravitational forces.
To Verify
While seated on the edge of the bed, does the person hold their head up and standup if they can weight bear?
If they cannot weight bear, they should be able to hold their head up for at least 10 minutes. This confirms ACL 2 Low.
To Rule Out
To rule out ACL 2 High, you simply need to ask them where they are going. If you do not speak their language, they can usually respond to gestures for the behaviors of sleeping, eating and washing their hands or needing to go to the bathroom.
The sense of direction does not require verification that they are going in the right direction for their stated location. Within ACL 2 High, we give them credit for a sense of knowing where they are going and being able to say so.
