Calculation
A nurse is preparing to administer valproic acid 400 mg PO bid for migraine headaches. Available is valproic acid 250 mg/5mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) In this case: Desired dose = 400 mg Concentration = 250 mg/5 mL = 50 mg/mL Plugging the values into the formula: Volume = 400 mg / 50 mg/mL = 8 mL
