Thank You

I am pretty much trying to teach myself how to do these calculations. I'm beginning my last semester in an ASN program and we have barely touched dosage calculations. They say we will hit it hard this upcoming semester..Critical care rotations..Anyway, I just received these problems in the mail from the school with a note to have them completed by the first class. I have Dosage Calculations Made Easy and many other pocket guides with formulas included. I'm still confused and don't know where to begin with these problems. If anyone could please explain them to me I will really appreciate the help!!! 1. The Dr. ordered Cordarone IV 900 mg to be added to 500 ml of D5W and run IV at a rate of 1mg/min for 6 hours. The manufacturer's directions agree with the Dr. order. The available 3 ml vials of Cordarone contain 50 mg per 1 ml. The infusion set delivers 60 drops per ml. A. How many ml of Cordarone IV should the nurse add to the 500 ml D5W? B. How many mg of drug are pesent in 1 ml of the Cordarone IV 900 mg in 500 ml of D5W solution? C. How many ml per minute must infuse to deliver the prescribed amount of drug? D.How mant ml per hour should the electronic infusion device be set to deliver? 2. The Dr. has ordered Intropin 200 mg to be added to 250 ml of D5W and run IV at a rate of 5 mcg/kg/min until the pt. systolic blood pressure is greater than 110 mmHg. The manufacturer directions agree with the Dr order. The available 5 ml vials of Intropin contain 200 mg. The IV set delivers 60 drops per 1 ml. A. How many ml of Intropin should the nurse add to the 250 ml D5W? B. Based on weight, how many mcg/min of Intropin should the pt. receive? C. How many mg of drug are present in 1 ml of the Intropin 200 mg in 250 ml D5W? D. How many ml per min must infuse to deliver prescribed amount? E. How many ml per hour should the IV device be set to deliver? Thank you
