A clinician orders 0.6 g of a drug to be given IV bolus. The solution concentration is 100 mg/mL. How many milliliters are required?

Explanation:
Calculating the dose in volume uses the simple relationship: Volume = Dose ÷ Concentration. First convert the prescribed dose to the same units as the concentration: 0.6 g is 600 mg. With a concentration of 100 mg per mL, the required volume is 600 mg ÷ 100 mg/mL = 6 mL. So 6 mL of the solution is needed to deliver the 0.6 g dose as an IV bolus. This approach directly ties together what you’re giving (dose) with how concentrated the solution is (concentration) to determine the correct fluid volume.
