A nurse is preparing to administer valproic acid 125 mg PO. Available is valproic acid syrup 250 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Identify the given information: Dose of valproic acid: 125 mg Concentration of valproic acid syrup: 250 mg/5 mL Calculate the volume of valproic acid syrup to be administered: Volume = Dose (mg) / Concentration (mg/mL) Substitute the values: Volume = 125 mg / (250 mg/5 mL) Volume = 2.5 mL
