A client is receiving a litre of 0.9% sodium chloride IV solution to be administered over 12 hours. The nurse should set the infusion pump to infuse how many mL per hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["83"]
Total volume to be infused = 1 litre
Convert the total volume from liters to milliliters:
Total volume (mL) = Total volume (liters) x 1000 mL/litre
= 1 litre x 1000 mL/litre
= 1000 mL
Total infusion time in hours = 12 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Total infusion time (hours)
= 1000 mL / 12 hours
≈ 83.33 mL/hour
Round to the nearest whole number:
Rounded infusion rate = 83 mL/hour

Correct Answer is ["1250"]
Explanation
Convert the child's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 55 pounds / 2.2 pounds/kg
= 25 kg
Calculate the total daily dose in milligrams:
Total daily dose (mg) = Prescribed dose (mg/kg/24 hours) x Child's weight (kg)
= 300 mg/kg/24 hours x 25 kg
= 7500 mg/24 hours
Determine the number of doses per day:
Number of doses per day = 24 hours / Frequency of doses (hours)
= 24 hours / 4 hours/dose
= 6 doses/day
Calculate the dose to administer for each dose:
Dose per administration (mg) = Total daily dose (mg) / Number of doses per day
= 7500 mg / 6 doses
= 1250 mg/dose
Correct Answer is ["300"]
Explanation
Calculate the total volume to be infused over 8 hours:
Total volume infused (mL) = Infusion rate (mL/hour) x Infusion time (hours)
= 75 mL/hour x 8 hours
= 600 mL
Calculate the remaining volume in the IV bag after 8 hours:
Remaining volume (mL) = Initial volume (mL) - Total volume infused (mL)
= 900 mL - 600 mL
= 300 mL
