I've done these before but for some reason I'm blanking out on how to complete this problem. I usually use dimensional analysis and I can't remember how to set it up.
1. The order is to infuse 1000 units heparin per hour from an available solution strength of 25,000 units in 500 ml D5W. Calculate the ml/hr rate.
2. A solution of 25,000 units heparin in 500 ml D5W to infuse at a rate of 1200 units per hour. Calculate the ml/hr rate.
3. A 500 ml D5W with 20,000 units heparin infusing at 1000 units/hour. An order states to increase by 240 units/hour. What is the new rate? (do you just add the 240 to the original 1000 units?)
