A nurse is preparing to administer dextrose 5% in water 40 mL IV to infuse over 20 min to a child. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["120"]
Step-by-Step Solution:
Determine the total infusion time in hours.
The infusion time is 20 minutes.
There are 60 minutes in an hour.
The infusion time in hours = 20 minutes / 60 minutes/hour = 0.3333 hours.
Calculate the infusion rate in mL/hr.
The total volume to be infused is 40 mL.
The infusion time is 0.3333 hours.
The infusion rate = 40 mL / 0.3333 hours = 120 mL/hr.

Explanation
Identify the given information:
Dose of ferrous fumarate: 3 mg/kg/day
Weight of the toddler: 22 lb
Concentration of ferrous fumarate drops: 45 mg/0.6 mL
Convert the toddler's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total daily dose of ferrous fumarate in mg:
Total daily dose = Dose/kg/day x Weight (kg)
Substitute the values:
Total daily dose = 3 mg/kg/day x 22 lb x (0.453592 kg/1 lb)
Total daily dose ≈ 29.97 mg
Calculate the dose per dose (every 8 hours):
Dose per dose = Total daily dose / 3
Substitute the values:
Dose per dose = 29.97 mg / 3
Dose per dose ≈ 9.99 mg
Calculate the volume of ferrous fumarate drops to be administered:
Volume = Dose per dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 9.99 mg / (45 mg/0.6 mL)
Volume ≈ 0.133 mL
Round the answer to the nearest tenth:
Volume ≈ 0.1 mL
Correct Answer is ["13"]
Explanation
Identify the given information:
Dose of acetaminophen: 400 mg
Concentration of acetaminophen liquid: 160 mg/5 mL
Calculate the volume of acetaminophen liquid to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 400 mg / (160 mg/5 mL)
Volume = 12.5 mL
Round the answer to the nearest whole number:
Volume ≈ 13 mL
