Determine the best expression for the label

Using the Dosage Calculations knowledge point

• Household measurements like "teaspoon" should be converted to metric units (\(\text{mL}\)) on prescription labels to avoid dosing errors.
• The concentration is \(250\text{ mg}/5\text{ mL}\), so a dose of \(1\text{ teaspoon}\) corresponds to \(5\text{ mL}\).
• Therefore, the dose is best expressed as \(5\text{ mL}\).

Answer:

• (A) 5 mL (Correct answer)
• (B) One tablespoon
• (C) One tablet
• (D) 500 mg
