Preparing for a polygraph test

[FutureNurse2005]

My sister has to take a polygraph test, and was wondering if there is anything she can do to prepare for it? She is quite nervous about it as we know that this sort of test is not always accurate:o

So, is there anyway to prepare for it? It measures your blood pressure, heart rate and "natural responses", I dont understand how it could be accurate if someone is out of their mind nervous! lol Wouldnt those things be way off before the test??

Has anyone had one before? Does anyone know anything about them?

I would appreciate any help you could offer.

Thanks:)

I had a polygraph years before I became a nurse when applying for a job with the police department as a dispatcher. After the test was over, I was told that I was the most honest person that had ever been polygraphed by them. I wasn't nervous because I answered truthfully no matter how embarrassing some of the questions were. I have nothing to hide so why be fearful? Just tell your sister to be straight up honest about EVERYTHING they ask her, and all will go just fine. :)

I don't know what else to say except answer truthfully. I think they do a baseline strip. this will indicate her nervousness.

She will do just fine if she answer with the truth because lieing will increase all responses being measured
