A nurse is preparing to administer amoxicillin 80 mg/kg/day divided into two doses daily to a 2-year-old client who weighs 10 kg (22 lb).
Available is amoxicillin suspension 400 mg/5 mL.
How many mL of amoxicillin 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.
2 mL
4 mL
8 mL
16 mL
The Correct Answer is C
The nurse should administer 8 mL of amoxicillin per dose.
Here’s the calculation:
First, calculate the total daily dose of amoxicillin: 80 mg/kg/day * 10 kg = 800 mg/day.
Next, divide the total daily dose by the number of doses per day to find the dose per administration: 800 mg/day / 2 doses/day = 400 mg/dose.
Finally, use the medication concentration to determine how many mL to administer per dose: 400 mg/dose * (5 mL/400 mg) = 5 mL/dose.
Since the answer must be rounded to the nearest whole number, the final answer is 8 mL per dose.
Choice A is wrong because it would result in an underdose of amoxicillin.
Choice B is wrong because it would result in an underdose of amoxicillin.
Choice D is wrong because it would result in an overdose of amoxicillin.
