A patient has been prescribed 200mg of Furosemide and they want it over 4 hours via a transfusion pump. The Furosemide has been made up to 250mg in 50mls. What is the rate and how much Furosemide is the patient getting each hour? ( X ml in 1 hour contains X mg of Furosemide)

Hey,
First of all, find out how how many mls is required for 200mg of furosemide (I would find out how many mls is required for 1mg and then times by 200). Then divide the total ml by 4 to get it per hour (as it is a 4 hour transfusion). This will give the Xml in 1 hour and then you can calculate how many Xmg is in that Xml (although you can just divide the prescribed amount by 4 as well).

Best wishes!
