A medication order is for 500 mg and is supplied as 1 g per 5 mL suspension. What volume is required for the dose?

Calculation: Ordered Dose: 500 mg Available Concentration: 1 g per 5 mL Convert grams to milligrams: 1 g = 1000 mg So, concentration = 1000 mg per 5 mL Calculate the volume to administer Volume to administer = (Ordered Dose ÷ Available Dose) × Volume Volume to administer = (500 ÷ 1000) × 5 Volume to administer = 0.5 × 5 = 2.5 mL
