A

3 recalled words = negative for cog impairment
1-2 recalled words + normal clock = negative
1-2 recalled words + abnormal clock = positive
0 recalled words = positive

21
Q

What is the impromptu testing method?

A

Put 3-5 common objects on the desk and ask patient to name and remember them, then put them out of sight.

Ask patient to draw large clock face and put all numbers ina nd set hands to 10 past 5

Ask patient to recall objects

(very similar to mini-cog)

22
Q

Series of 6 questions to test cognition:

Abnormal = >7
