Even when the question doesn't reveal results of the 3 diagnotic tests (ppd, chest xray, AFB), why do i still give prophylactic INH? Is it like a precaution?
I assumed "exposure" meant "positive ppd, but negative chest xray." I shouldn't have done this to the question, but I'm filipino and I remembered when i came back from the Philippines my ppd was postive but my chest xray was negative, and my doctor didn't give me INH. That's why i chose the answer that said to do nothing.. another wrong move with nlcex questions lol. :P
