In pediatric continued severe pain management, 0.25 ml IM non-diluted corresponds to how many milligrams?

• A. 10 mg
• B. 50 mg
• C. 25 mg
• D. 100 mg

Answer: (C)

The key idea is dose = volume × concentration. If the preparation is non-diluted at 100 mg per milliliter, then a 0.25 mL dose contains 0.25 × 100 mg = 25 mg. So the correct dose is 25 mg. If the concentration were different, the calculation would change accordingly (for example, 0.25 mL at 10 mg/mL would be 2.5 mg). Always verify the labeled concentration on the vial before calculating.
