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.

Correct Answer is C
Explanation
The correct answer is d. Exhibits head lag when pulled to a sitting position.
Choice A: Unable to hold a bottle At around 6 months of age, some babies can hold their own bottle. This is not a concerning finding for a 5-month-old infant. Therefore, this is not the correct answer.
Choice B: Unable to roll from back to abdomen Rolling over often starts around 4-6 months, so it’s not unusual for a 5-month-old to still be developing this skill. Therefore, this is not the correct answer.
Choice C: Absent grasp reflex The grasp reflex is an involuntary movement that your baby starts making in utero and continues doing until around 6 months of age. The grasp reflex lasts until the baby is about 5 to 6 months old. Therefore, this is not the correct answer.
Choice D: Exhibits head lag when pulled to a sitting position By the age of 5 months, most infants have developed enough strength in their neck and upper body to control their head movement. This means they should not exhibit a significant head lag when pulled to a sitting position1. If this is not the case, it could indicate a delay in motor development or a potential neurological issue, which should be reported to the healthcare provider for further evaluation. Therefore, this is the correct answer.
