Correct Answer is ["50"]

Explanation

Step 1: The total amount of phenytoin required per dose is 250 mg.

Step 2: Each 5 mL of oral solution contains 25 mg of phenytoin.

Step 3: To find out how many mL are needed, we divide the total amount required by the amount in each 5 mL of oral solution. So, (250 mg ÷ 25 mg/5 mL).

Step 4: The result is 50 mL.

So, the nurse should administer 50 mL per dose. This is already a whole number, so no rounding is necessary.
