I'm in my first semester of my last year of nursing school and I still struggle with the math. I had to withdraw from classes early last semester so I never got a good handle on figuring out the problems...and there is always the dimensional analysis vs. formula debate ( I typically work with formula...). Can someone explain how to solve this problem and/or recommend a good website?
A newly admitted patient is to recieve 1250 u of heparin per hour continuously. The solution available is 1 L D% 1/4 NS with 50000 u of heparin. Set calibration is 15 gtt/mL. Calculate the hourly flow rate and gtt/min.
(The answer key says 25 mL/hr and 6gtt/min...but im not understanding how they got those answers

Well I see how it is 6gtt/min. Use the 25mL/h.
25mL/60 min x 15gtt/mL = 6.25 = round to 6 gtt/min
but I don't see how you can get mL/h... they didn't give you an amount of time.. they just said continuously. But you need the mL/h to get the gtt/min, hopefully someone else can help!
