A nurse is preparing to administer amoxicillin 500 mg PO every 12 hr. The amount available is amoxicillin 250 mg/5 mL suspension. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Desired dose per administration = 500 mg. Available concentration = 250 mg/5 mL. Calculate the volume in milliliters (mL) to administer per dose. Volume (mL) = Desired dose (mg) / (Available concentration (mg) / Available volume (mL)) = 500 mg / (250 mg / 5 mL) = 500 mg / 50 mg/mL = 10 mL.
