Take N non-empty items from clojure set

I have a set (I think) of items; similar to this: 

(def a ({:answers 3 :comments 12} {} {} {:answers 43 :comments 23} {}))

I want to ideally remove all empty items in that list, but keep the set intact otherwise.. what I am trying to do is: 

(defn drop-empty-items
 [a]
 (take-when #(not empty? %) a))

but this obviously doesn't work at all..

How do I do this, please?

I'm trying to return something to the effect of: 

({:answers 3 :comments 12} {:answers 43 :comments 23})

from drop-empty-items

(def a '({:answers 3 :comments 12} {} {} {:answers 43 :comments 23} {}))

(remove empty? a) 
;=> ({:answers 3, :comments 12} {:answers 43, :comments 23})
