A nurse is preparing to administer cefoxitin 80 mg/kg/day IV every 6 hours to a 6 year-old child who weighs 20 kg. 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.)
Correct answer
400
Rationale
To calculate the correct dose for the child, we first need to determine the total daily dose. The child weighs 20 kg, so the total daily dose would be 80 mg/kg/day x 20 kg = 1600 mg/day. Since the medication is to be given every 6 hours, the total daily dose needs to be divided into 4 doses. Therefore, 1600 mg/day ├À 4 doses = 400 mg per dose. Hence, the correct answer is A: 400 mg. Other choices are incorrect because they do not follow the correct calculation process.
