Correct Answer is ["63"]
Explanation
Flow rate (mL/hr)=Total volume (mL)/Infusion time (hr)
Insert the given values:
Total volume = 500 mL.
Infusion time = 8 hr.
Flow rate=500 mL/8 hr=62.5 mL/hr.
Round to the nearest whole number:
62.5 rounds to 63 mL/hr
Correct Answer is ["3.5"]
Explanation
Convert the child’s weight from pounds to kilograms:
52 lb÷2.2=23.6 kg.
Calculate the total daily dose in micrograms (mcg):
7.5 mcg/kg/day×23.6 kg=177 mcg/day.
Determine the volume in mL to administer:
The elixir concentration is 50 mcg/mL
177 mcg÷50 mcg/mL=3.54 mL.
Round to the nearest tenth:
3.54 rounds to 3.5 mL.
