We gave our first IV push med today....I used a formula and my calculator to figure the IV push rate and it was correct.
However, our instructor wanted us to figure it in our head using the marks on the syringe. We used 3 mL syringe which is 30 marks.
The question is if you have drawn up 50mg/mL diluted with 3 mL NS (we gave Demerol) and you only want to give 12.5mg how do you do this in your head?
okay after reading this thread I am not quite sure why you add the extra 1 ml of the dermol is this protcol for the med? I know I should look this up however, i thought i would ask first for their opinion first. i was taught like daytonite stated above.
I read the question as posted at the bottom from the OP:
"The question is if you have drawn up 50mg/mL diluted with 3 mL NS how do you do this in your head? "
So 1ml for the Demerol and diluted with 3 ml of NS to me means that you now have 4ml of fluid irregardless of the size of the syringe (maybe it should say, 50mg/ml diluted to 3ml with NS). It is not a problem of the math we all agree on that it is just how you interpret the question. I guess different backgrounds give you different perspectives.
Heh heh. It's amazing how quickly a post can be misinterpreted.
I agree with all the above suggestions.
It all comes down to your comfort level in math, as well as what is your habit.
Whether it's 'halfing', or adding/diluting a solution to make it more compatible/easier to calculate.
As long as you can rationalize and get the correct answer, it really doesn't matter how you do it. Some nurses use formulas, others use charts and graphs.
Each to his/her own.
Best of luck.
