A nurse is preparing to administer amoxicillin 350 mg PO. Available is amoxicillin 250 mg/5 mL. How many mL should the nurse administer? (Round to the nearest whole number.)

Desired dose = 350 mg. Available concentration = 250 mg / 5 mL. Calculate the volume to administer. Volume (mL) = Desired dose (mg) / Available concentration (mg/mL) = 350 mg / (250 mg / 5 mL) = 350 mg × (5 mL / 250 mg) = (350 × 5) / 250 mL = 1750 / 250 mL = 7 mL.
