Dosage Calculation Question......help please

Hello all!

I'm a level II Practical Nursing student in need of help with a calculations question.

Q: A clinet has orders for 40units of insulin. There are no insulin syringes available. The nurse's only recourse is to use a tuberculin syringe to draw up the insulin. Using the TB syringe, how may cc will the draw be to deliver 40units of insulin?

a. 0.15cc

b. 3cc

c. 0.4cc

d. 1cc

If 1 units = 100ml...so would you divide 100ml by 40. I did that and got 0.4. Is that correct?

Thanks in advance.

    NEVER substitute a TB for Insulin Syringe. GO somewhere else and FIND the appropiate syringe. Another floor, Central, Pharmacy whereever in your institution syringes are stocked.

    Thanks MERRYWIDOW46! In a real situation I would find a insulin syringe from another department (naturally). However, this is just a math question on a worksheet. I'm trying to find out if the answer I came up with is correct?

    Thank you for taking the time to respond.

    I need to make a note here, the formula is written just a little bit backward. The conversion is: 100 units of insulin equals 1 milliliter.

    I also got the same answer of 0.4mL.
