I have this medication calculation problems and I have been trying to solve them but I just can't find the right solutions The displacement value for co-amoxiclav is 0.9ml per 1.2g vial. What volume of water for injection would you add to the vial to give a concentration of 60mg in 1ml? A bag of 0.2% lignocaine is prescribed at a rate of 3mg per minute for a 65kg lady. At what rate should the infusion run in ml/hr?

welcome to an! the largest online nursing community!
i answered this in your other post. we are happy to help but we won't do the problem for you. what did you come up with? show us your work so we can help you better and figure out where you are having trouble.
if the displacement value is 0.9 per 1.2g. there is 1.2g per 1ml, right? so if you have 1.2g in 1 ml how many cc would you have to add to have a final concentration of 60 mgs per 1ml. watch your decimal points.
if you have a 2% solution of lidocaine....
how many grams is that? then.....
how many milligrams is that per bag of ivf
how many mg of lidocaine is in the iv bag?
what is the concentration of the drug in the bag?
what is the drug concentration per cc in the bag?
how many cc/hr is needed to deliver 3mg/min
if the dose is just 3mg/min do you really need the weight?
