A nurse is preparing to administer phenytoin 100 mg oral suspension PO to a school-age child who has epilepsy. According to the medication label. What is the total dose of the container? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Identify the given information: Concentration of phenytoin oral suspension: 100 mg/4 mL Volume of the container: 4 mL Calculate the total dose of phenytoin: Total dose = Concentration (mg/mL) x Volume (mL) Substitute the values: Total dose = 100 mg/4 mL x 4 mL Calculate the result: Total dose = 100 mg
