10, 15, 20, 60?I am trying to get a head start on my dosage and calculations for my last semester of school (school doesn't start for another week). I can figure out dosage, times, settings, concentration, etc, with no problems. But with a few of the questions, they ask, "which tubing would you use for....?" I've never thought of that. So, here's the question-1g Keflin in 50mL D5W to infuse in 20 min. Choose the appropriate tubing for this infusion:A. 10gtts/mLB. 15 gtts/mLC. 20 gtts/mLD. 60 gtts/mLI set up my problem like this:50mL------ X (type of tubing) = _____gtt/min20 minDoing the math, the answers are:A would come out to 25 gtt/minB would come out to 37.5 gtt/minD would come out to 150gtt/minSo which one do I choose? How do you know which tubing to use?
