The nurse calculates a medication dosage. The order reads 500mg PO, available is 250mg per tablet. How many tablets should be administered?

✓ Correct Answer: Option B

Dosage calculation: Desired/Have × Quantity = 500mg/250mg × 1 tablet = 2 tablets. Always double-check calculations, especially for high-alert medications. Use unit analysis or ratio-proportion method. Independent double-check for high-risk meds.
