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"]
Explanation
1 tablespoon (Tbsp) = 15 milliliters (mL).
Calculate the dose in tablespoons:
15 mL÷15 mL/Tbsp=1
Round to the nearest whole number: 1 Tbsp
Correct Answer is ["0.45"]
Explanation
Calculating the total dose in mg:
Convert the child's weight to kg: 74 lb ÷ 2.2 lb/kg = 33.64 kg
Calculate the total dose: 33.64 kg × 4 mcg/kg = 134.56 mcg
Converting mcg to mg:
1 mg = 1000 mcg
134.56 mcg ÷ 1000 mcg/mg = 0.13456 mg
Calculating the volume to administer:
Use the concentration of the medication: 0.13456 mg ÷ 0.3 mg/mL = 0.45 mL
