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 to pump to deliver? (Enter numerical value only.)
The Correct Answer is ["100"]
Given:
Volume of fluid: 2 liters (1 liter = 1000 mL, so 2 liters = 2000 mL)
Infusion time: 20 hours
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 2000 mL / 20 hr
Flow rate (mL/hr) = 100 mL/hr

Correct Answer is ["40"]
Explanation
Given:
Vial strength: Cefotaxime 2 grams (2000 mg)
Volume of diluent: 50 mL of normal saline
Step 1: Calculate the concentration of Cefotaxime in the reconstituted solution:
Concentration (mg/mL) = Total amount of Cefotaxime (mg) / Total volume of solution (mL)
Concentration (mg/mL) = 2000 mg / 50 mL
Concentration (mg/mL) = 40 mg/mL
Correct Answer is ["83"]
Explanation
Given:
Volume of fluid: 2 liters (1 liter = 1000 mL, so 2 liters = 2000 mL)
Infusion time: 24 hours
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 2000 mL / 24 hr
Flow rate (mL/hr) = 83.33 mL/hr
Step 2: Round to the nearest whole number:
Flow rate (mL/hr) ≈ 83 mL/hr
