Dose Calculation - 服用量の計算 -
|Sam:||Hi, Jenny. How was your home visit with Mr. Drew?|
|Jenny:||Hi, Sam. It was fine. He's doing much better now.|
|Sam:||That's good news. By the way can I ask you a favor?|
|Jenny:||Sure. What is it?|
|Sam:||I have to calculate the rate of the intravenous infusion. I need to know how many hours it will take for the patient to receive his full dose of medication.|
|Jenny:||Let’s see. The doctor ordered an IV infusion of a full dose of a hundred milligrams with a flow rate of 10 mg per hour. What is the concentration of the intravenous medication you have?|
|Sam:||I have a 50 mL intravenous infusion bottle with a concentration of 10 mg per 5 mL.|
|Jenny:||We can use the conversion factor to get the correct number of hours. First, we need to convert mL to mg and then mg to hours. So, multiply 50 mL by 10 mg and divide by 5 mL. That equals a 100 mg. Next, a 100 mg multiply by 1 hour equals a 100 mg per hour. Divide that by 10 mg, and the result is 10 hours.|
|Sam:||Thank you. Can I try?|
