It should say on the bottle how many units are in a ml.Where I work the Heparin is supplied in a 10,000 units/ml bottle so you would give 0.5ml.You need to check the bottle to make sure you are giving the right dosage.
the order is give 5000 units subcutaneously. if i am using a 1cc or 1ml syringe, how far would i pull the stopper of the syringe back? would i draw up to 0.5ml? also, is 0.5ml equal to 5000 units?
I'm glad that you're here asking questions, but I hope you realize that you don't have all of the information to calculate a safe injection. For once, I'm going to say that I hope you're a student asking a homework question
What is the strength of your Heparin? You cannot expect us to know if .5 ml equals anything unless we know the strength (units or mg per ml).
OP, never sit around and ponder what is right/wrong with drug admin. Always go directly to your references.
You need to constantly refer to your drug reference which = medication instructions that come with the medication, your pharmacy instructions, and your own drug references at hand. I would rec getting downloadable and FREE references to quickly look at when you have a question pop in your head and you are not working at a facility with a facility approved electronic drug reference.
