Did appropriate introductions to Treasury obtain approval? (4)

I believe the answer is:
took
'did' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps you can see an association between them that I can't see?
'introductions to treasury obtain approval?' is the wordplay.
'introductions to' indicates taking the first letters.
'approval?' becomes 'ok' (OK is an example).
The first letters of 'treasury obtain' is 'to'.
'to'+'ok'='TOOK'
'appropriate' acts as a link.
Can you help me to learn more?
(Other definitions for took that I've seen before include "Went through" , "Purloined" , "Gained; stole; made (notes)" , "Captured" , "Stole - accepted" .)
