A nurse is preparing to administer valproic acid 500 mg PO. Available is valproic acid oral solution 250 mg/5 mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["10"]

Step 1: Determine the Medication Concentration

The total amount of medication in the solution is 250 mg.
The total volume of the solution is 5 mL.
To find the concentration per mL:
250 mg ÷ 5 mL = 50 mg/mL

Step 2: Determine the Required Volume

The prescribed dose is 500 mg.
To find the volume needed:
500 mg ÷ 50 mg/mL = 10 mL

Thus, the nurse should administer 10 mL of the solution to deliver the required 500 mg dose.
