I made a mistake, i thought my thinking was wrong lol, its D.. vasospasm is very very rare for GERD..
But when you look @ metaplasia of esophagus,, 5-15% of patients have symptoms of GERD... plus i failed 2 notice that this has been occuring for 8 months, meaning its chronic and very likely of metaplasia lol... The trick is the period of symptoms.
Hope 2 god i didn't get this q on the exam hahaha. I think this q is in the kaplan q bank as well lol.. always remember, first guess are the best answers lol..
