Question 1 of 5
A nurse is preparing to administer cefoxitin 80 mg/kg/day IV every 6 hr 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: The correct answer is 400 mg per dose.
To calculate this, first, determine the total daily dose: 80 mg/kg/day x 20 kg = 1600 mg/day. Next, divide this total by the number of doses per day: 1600 mg/day / 4 doses = 400 mg per dose. This ensures the child receives the appropriate amount of cefoxitin at each administration.
Incorrect answers:
A: 200 mg - Half of the correct dose, not sufficient.
B: 600 mg - Excessive dose, could lead to adverse effects.
C: 100 mg - Insufficient dose, may not be effective.
D: 300 mg - Below the correct dose, inadequate treatment.
E: 500 mg - Close but not rounded to the nearest whole number.
F: 700 mg - Excessive dose, could lead to adverse effects.
G: 350 mg - Below the correct dose, inadequate treatment.
