A nurse is preparing to administer 0.33% sodium chloride 120 mL IV to infuse over 30 min to a preschooler. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["240"]
Step-by-step calculation:
The nurse needs to administer 120 mL of sodium chloride.
The infusion time is 30 minutes.
Calculating the flow rate in mL/hr:
Convert the infusion time to hours: 30 minutes ÷ 60 minutes/hour = 0.5 hours
Divide the total volume by the infusion time: 120 mL ÷ 0.5 hours = 240 mL/hour

Correct Answer is ["1.3"]
Explanation
Step-by-step calculation:
The child's weight is 55 lb.
The medication dosage is 2 mg/kg.
The available medication concentration is 40 mg/mL.
Calculating the total dose in mg:
Convert the child's weight to kg: 55 lb ÷ 2.2 lb/kg = 25 kg
Calculate the total dose: 25 kg × 2 mg/kg = 50 mg
Calculating the volume to administer:
Use the concentration of the medication: 50 mg ÷ 40 mg/mL = 1.25 mL
Rounding the answer:1.25 rounds to 1.3 mL
Correct Answer is ["1.2"]
Explanation
To calculate the dose:
Convert the child’s weight from pounds to kilograms:
1 kg = 2.2 lb
51 lb÷2.2=23.2 kg
Calculate the prescribed dose in mg:
0.1 mg/kg×23.2 kg=2.32 mg
Determine the volume in mL to administer:
The concentration of the medication is 2 mg/mL.
2.32 mg÷2 mg/mL=1.16 mL
Round to the nearest tenth:
1.16 = 1.2 mL
