Question 1 of 53 :
The healthcare provider prescribes amoxicillin 500 mg every 8 hours for a child who weighs 88 pounds. The recommended maximum safe dose is 50 mg/kg/24 hour. The available suspension is labeled, Amoxicillin Suspension 250 mg/5 mL. Based on this child weight, how many mL should the nurse administer ? (Enter numerical value only. (If rounding is required, round to the whole number.)
Correct Answer: 10 mL
· Convert pounds to kilograms:
- 88 lb * (1 kg / 2.2 lb) = 40 kg
· Calculate the maximum daily dose:
- 50 mg/kg/day * 40 kg = 2000 mg/day
Prescribed dose:
500mg every 8 hours
24hrs/8= 3 doses
Each dose= 500mg
Daily dose =500mg X 3= 1500mg
Available formulation= 250mg/5ml
Ml to administer per day = 1500 X 5/250= 30ml
Each dose= 30ml/3= 10ml
