hello this is the uh video for reconstituting drugs the key to reconstituting drugs is on the label you'll see why wouldn't we get a little further in when you get some medications from the pharmacy not all of the injectable drugs are going to be a liquid some of them come as little dried cakes or wafers or powders in a glass bottle and you'll have to inject a fluid into the bottle to dissolve or liquefy the powder so that it can be injected it's not strange for this to happen say for example in the left-hand vial there's a cake of dry dried medication and it'll be your job to uh inject a deal you want a diluent is just a fancy word for the liquid you're going to inject in to dissolve the medication and the label should tell you which type of liquid to inject here are some examples zosin is an antibiotic on the left and if you look at the bottom parts of the bottles you can see that there's a powdery material the same for the medication in the middle and on the right hand side you can see that there's a little ring of like a little wafer that has to be dissolved sometimes you'll see these bottles attached to iv bags this happens pretty common the there's usually a seal that has to be broken and then the water is squeezed from the bag into the bottle the little wafer is dissolved and then it's flipped upside down and you drain the water back into the bag now when i said the key is on the label uh it really is when you're reconstituting medications everything that you need is right on the label here if you look at the the red box it tells you to reconstitute with 10 milliliters of sterile diluent let's look a little closer so when you're looking at the label look at the instructions because that gives you the information you need to reconstitute the medication here reconstitute with 10 milliliters of sterile diluent okay so we know that we're going to inject 10 milliliters and the next important thing that we see is it gives you a dose of or a concentration of 60 milligrams per milliliter those are the things that you need to see on the label to do the math calculations here's an example of a medication box so if we're going to reconstitute this medication the first thing we're going to do is look at the instructions so looking at this the first step is to find the information that we need and if we read through it we can see that it says to add 80 milliliters of sterile water okay next thing we need to look at the medication order oh i'm sorry again if you look at it once i'm sorry back to step one you inject the 80 milliliters of sterile water and it'll give you a concentration of 0.5 milligrams of the mitomycin in each milliliter so 0.5 milligrams per milliliter then step two uh let's we'll read the doctor's order and say for example it says to give 1.5 milligrams of mitomycin so the next step is we set up the ratio proportion we've kind of touched on this a little bit during the past few videos and the uh better instructions are coming up in the next unit but if we kind of look at this then this is how we set it up as the 0.5 over 1 and what we need to administer is 1.5 milligrams so the x is the milliliters that we need to calculate so we cross multiply and come up with 0.5 x equals 1.5 we have to get x alone so we divide by 0.5 and x comes to 3 milliliters now there's something a little different on this label uh it's a little hard to see i apologize for that but if we kind of zoom in you'll see that some labels will give you additional information if you need to get a specific concentration you can add different volumes of fluid say for example if you want to get a concentration of 200 milligrams per milliliter it says to inject 4.2 milliliters if you want to get a concentration of 400 milligrams per milliliter then you add 1.8 milliliters of fluid so adding a different amount of fluid affects the concentration so some of them will give you different options like this and the amount of fluid that you're going to inject really depends on what the order is to uh to give okay that's going to be the end of this lecture practice sheets should be up what i would recommend doing though is on the this practice sheet go ahead and look at the next unit first the ratio proportion that will help you some in doing this practice sheet okay thank you
