A medication order for a patient weighing 60 Kg calls for 2500 units/kg of body weight of an antibiotic in 500mL D5W by IVdrip. The antibiotic is available in 10ml vials containing 200,000 units. How many milliliters of the medications should beadded to the bag of D5W to prepare the infusion?A. 16.5mlsB. 80mlsC. 0.75mlsD. 7.5mls

Answer 1

The first step to answer this question is to find the number of units needed for the 60kg patient:

$60kg\cdot\frac{2500u}{kg}=150000u$

Now, use the conversion factor that states that 10mL contain 200000 units to find the number of mililiters needed:

$150000u\cdot\frac{10mL}{200000u}=7.5mL$

It means that 7.5mL are needed.

The correct answer is D. 7.5mLs.
