A client receives a prescription for lactated Ringer’s 2 liters IV to be infused over 20 hours. How many mL should the nurse program the infusion pump to deliver? (Enter numerical value only.)
The Correct Answer is ["100"]
Calculation:
Convert the total volume from liters to milliliters:
Total volume (mL) = Total volume (liters) x 1000 mL/liter
= 2 liters x 1000 mL/liter
= 2000 mL
Total infusion time in hours = 20 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Total infusion time (hours)
= 2000 mL / 20 hours
= 100 mL/hour

Correct Answer is ["0.4"]
Explanation
Calculation:
Calculate the total daily dose in milligrams:
Total daily dose (mg) = Prescribed dose (mg/kg/day) x Child's weight (kg)
= 1.5 mg/kg/day x 42 kg
= 63 mg/day
Determine the number of doses per day:
Number of doses per day = 24 hours / Frequency of doses (hours)
= 24 hours / 6 hours/dose
= 4 doses/day
Calculate the dose to administer with each dose:
Dose per administration (mg) = Total daily dose (mg) / Number of doses per day
= 63 mg / 4 doses
= 15.75 mg
Calculate the volume to administer with each dose in mL:
Volume per dose (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 15.75 mg / 40 mg/mL
=0.39375 mL
Round to the nearest tenth:
= 0.4 mL
Correct Answer is ["0.7"]
Explanation
Calculation:
Desired dose = 35 mg
Available concentration = 50 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 35 mg / 50 mg/mL
= 0.7 mL
