A provider order states kanamycin 700 mg im, the kanamycin label states to add 5ml of sterile water to 1 gram kanamycin, how many milliliters should be given

Answer : 0.14 mL of sterile water should be added to 700 mg of kanamycin.

Explanation : We know that 5 mL of sterile water has to be added to 1 gram of kanamycin so we have to find for 700 mg;

We can use the comparison formula here, where the unknown volume of sterile water in mL can be calculated;

700 mg / (1000 mg X 5 mL) = 0.14 mL

Hence, 0.14 mL will be added to 700 mg of karamycin.
