anyone can recommend a website for drug calculations esp for small dosage. For ex when dose ordered comes out to 0.07ml and you have to add saline and end up giving 0.7 ml. Meds such as lasix,... Read More

So if we add saline to that syringe (vs adding that syringe to saline), we have more medicine than we have accounted for.We usually draw up the 0.07ml into a TB syringe and then add saline to it to make it 0.7ml total. So we don't dilute the lasix or other drug in it's original vial. We draw up only what we need from it.
We have a policy for fentanyl dilution. It comes 100mcg/2ml. We draw up the 2ml, then mix with 18ml NS to equal 100mcg/20ml or 5mcg/ml. Then we draw our dose from that.
I think that it's safer to dilute first.
