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.
A. 2 mL
Choice A is wrong because it would result in an underdose of amoxicillin.
B. 4 mL
Choice B is wrong because it would result in an underdose of amoxicillin.
C. 8 mL
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.
D. 16 mL
Choice D is wrong because it would result in an overdose of amoxicillin.
