If nerve stimulation is used (0.5 mA, 0.1 msec), the passage of the needle through the fascia iliaca and contact of the needle tip with the femoral nerve usually is associated with a motor response of the quadriceps muscle group.
Best Answer: I'm not 100% sure on this either, but it's my understanding that your actual rank doesn't have anything to do with it; the exact/decile/quintile/quartile/none is all about the system your school uses in their class rank.owever, when you select one of the others, it asks for which decile/quartile/quintile you're in rather than your specific rank, so I'm pretty sure you would choose exact. That's the one I'm going with on mine as well (: Hopefully that made sense.
Quartiles are a useful measure of spread because they are much less affected by outliers or a skewed data set than the equivalent measures of mean and standard deviation. For this reason, quartiles are often reported along with the median as the best choice of measure of spread and central tendency, respectively, when dealing with skewed and/or data with outliers. A common way of expressing quartiles is as an interquartile range.
