Question about PCA on my pharm exam

[mb1949]

I had a pharm calculation exam today, one question I don't remember the exact wording, but it was fentanyl, infusing I assumed through a PCA, we were told by professor not to round up fentanyl, the answer came out something like 6.75ml/hr If I remember correctly, the only PCA I have seen can be programmed to the tenth but not the hundreth, any way I didn't round but some of my fellow students did, can we round this up or not, I am very confused on this on.

My school's rule for dosage calc. is 2 decimal places. I would fight it if it came back wrong though. They did not specify as to how much to round it by.

My school's rounding rules state that if the answer is greater than 1 ml round to 10th place if less than 1 ml round to 100ths.

Isn't it confusing usually we round to the tenth, unless its mL/hr than we round up to whole numbers, however I still don't understand this fentanyl and pca thing, oh well I quess I will find out monday, thanks fellow student nurses
