A Syringe Question

Daytonite, BSN, RN · May 2, 2006

i've been trying to find a good image of a tb syringe on the internet and i just can't come across one for you to look at. a tb syringe holds a total of 1cc, or 1ml, of fluid. this 1cc is divided into 10 equal parts, or .1cc sections. the longer marks on the barrel are for these tenths of a cc, or .1cc increments. there are also another 10 markings inbetween each of the .1cc marks. each of those marks is .01cc. in all, there are a total of 100, .01cc marks on the barrel of a tb syringe. some manufacturers, only make 5 marks between the .1cc sections so that each one of those small sections represents .02cc. resulting in only a total of 50 marks on the barrel of the syringe. when you are shading off an amount, it is crucial that you first convert your dose into a decimal. once you have your decimal figure, locate all the .1cc marks on the syringe (there are 10 of them). the first one starts at the hub (where the needle is attached). as you move along the barrel these numbers increase (.1, .2, .3, .4, .5, etc) until you reach 1.0cc. the first number after the decimal point is where you will shade to on the syringe's .1 marks. if there is another number following that, you will shade just a few hundredths marks more but not beyond the next .1 mark. does that help you at all?

for example, if you are to give 3/4cc, you would convert that to .75cc. (divide 4 into 3) and shade as follows (.75 rounds up to .76):

Is this the only problem you had with your test? I have lots of websites with practice medication problems on them. I don't think any of them have any pictures of syringes on them, however. At least, I don't remember any of them having them.

OK, normally I wouldn't go to a VET site to look for insulin syringe dosing pictures, but this site was too good--and these pictures are very nice and accurate, so I hope that helps. Remember, these are insulin syringes and measures in UNITS, not CCs or MLs, but you still get to see how to count the little lines.

This is a 1 ml/cc syringe. The teaching looks good so it might help to visit that site for more information.

Good luck on your test!
