How to say "Are you nuts?"
I am not sure how much used is 気が変. But I have personally never heard it.

The most accurate expression I can think of now would be :

> 頭がおかしい

You could also use :

> 馬鹿{ばか} - 阿呆{あほう}

Which are useful to express shock after someone do something dangerous or
stupid.

answer
「気{き}が変{へん}になったか。」 makes sense and it is not bad at all, but that plain
か-ending makes it sound a little stiff.

You could say:

「正気{しょうき}で言{い}ってるの？」

「頭{あたま}おかしいんじゃない？」

「気が狂{くる}っちゃったんじゃないの？」

「気は確{たし}か（なの）？」
