A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["500"]
To calculate the dose of erythromycin per administration, you can follow these steps:
- Determine the total daily dose: 2 g.
- Divide the total daily dose by the number of equally divided doses per day: 2 g / 4 doses =
0.5 g per dose.
- Convert grams to milligrams: 0.5 g * 1000 mg/g = 500 mg.
So, the nurse should administer 500 mg of erythromycin per dose.
