# simple math problem

Published

Hi I am a nursing student with a simple question to a simple math problem. It maybe that I am over thinking the answer to the question that this problem has me stumped. If anyone knows the answer it would be a great help!

Question: Ancef 1 Gram in 10 ml syringe. How many mg/ml are in the syringe? How many mls/hr will you set the pump?

First ---- 1 gram = 1000 mg. so if there is 1000 mg, you still have 10 ml (right?)

you are missing the time it is to run over.

Thanks... I got that far but that is how the question read so I thought it was asking for the mls over one hours time.

Since 1 gm equals 1000 mg, and your question is how many mg per 1 ml, you need to divide 1000 by 10 which will give you 100mg/ml.

If using a syringe pump, this is given over 3-5 minutes into a large vein or side port of a free-flowing line.

If Ancef is further reconstituted in 50-100cc of a diluent, it is normal to administer it over 30 minutes.

Your concerns are diluent/drug ratio to prevent incompatibilities (precipitations can occur with concentrations of Ancef in NS when your ratio is > 300mg of drug in one ml of diluent) and osmolarity. Increasing your diluent will decrease your osmolarity which in turn decreases the trauma to the Tunica Intima of the vein.

Hope this helps!

Your information can be obtained by looking in a drug book... Isn't that a reference all should be using with queries such as this?

this was labeled a math problem not a med adm prob......if you assume a rate, would you not be practicing med without benefit of lic?.....if i received this order i might look it up and THEN call the doc with the usual/standard time frame and GET the order........unless this is a standing order on the unit you work on.....

The MD will NEVER give you a rate of administration for Ancef, or most other medications... He or she will only give you the drug, drug amt and how often it needs to be administered. It is your responsibility to obtain the additional information.

Well, It is truly wonderful if you have MD's who would tolerate a phone call to them requesting that type of info!
