0.5 teaspoons should be administered.

Explanation:

One teaspoon is approximately equal to five milliliters.

1 teaspoon = 5 ml

The label on the vial states 100 mg per ml.

1 ml = 100 mg

5 ml = 500 mg = 1 teaspoon

That is 500 mg = 1 teaspoon

The physician writes an order for 250 mg of a medication for a patient

500 mg = 1 teaspoon

250 mg = 0.5 teaspoon

So 0.5 teaspoons should be administered.
