Chinese phrase in Lost episode S3.18 "D.O.C." (Spoilers for season 3)

If you're familiar with this episode you'll probably know that Naomi (the one who crash landed) spoke a few different language, one of which was Chinese. 

After about 5 listens I thought it sounded like "qu le shen me shi" but according to Lostpedia it's actually 出了什么事? [chū le shén me shì]. Is this a common phrase?
