Kantrex IM TO be given

Question

A provider order states kantrex 700 mg IV now the kantrex label states to add five mills of sterile water to 1 g of kantrex ; 0.5g=2ml. How many milliliters Should be given

Answer 1

Hi Leticia,

I can help you here. The formula is:

Dose you want

____________ X amount of liquid

Dose you have

You WANT 700mg you HAVE 1g (1000mg) in 5ml of LIQUID

700 divided by 1000 = .7 X 5 = 3.5ml (you would administer 3.5ml to the patient)

Remember to always use the same units - for example make sure everything is in milligrams (700mg & 1000mg) instead 700mg and 1g. You need to convert 1g into 1000mg.

Does that make sense?
