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.)

Calculation: Desired dose = 350 mg. Available concentration = 250 mg / 5 mL = 50 mg/mL. Calculate the volume to administer in milliliters (mL). Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) = 350 mg / 50 mg/mL = 7 mL.
