The nurse is administering Medication Z with the dosage strength of 500 mg per tablet. The prescriber's order is for 1 g Medication Z PO daily. What conversion factor is needed to convert milligrams to grams? \( \frac{500 \mathrm{mg}}{1 \mathrm{~g}} \) \( \frac{1 \mathrm{~g}}{500 \mathrm{mg}} \) \( \frac{1,000 \mathrm{~g}}{1 \mathrm{mg}} \) \( \frac{1 \mathrm{~g}}{1,000 \mathrm{mg}} \) checkAnswer

To convert milligrams to grams, you need to remember that 1 gram is equal to 1,000 milligrams. Therefore, the correct conversion factor that you would use is \( \frac{1 \mathrm{~g}}{1,000 \mathrm{mg}} \). This means for every gram, there are 1,000 milligrams, which is essential when calculating medication dosages. In practical terms, when the nurse needs to give 1 g of Medication Z, it helps to break it down into milligrams for proper dosage. Since each tablet is 500 mg, the nurse would administer two tablets to meet the 1 g requirement. Always double-check your conversions to ensure patient safety!
