A client is receiving a 200 ml bolus of 0.9% sodium chloride to be infused over 20 minutes. The nurse should set the infusion pump deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["600"]
Given:
Volume of fluid: 200 mL
Infusion time: 20 minutes
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Convert infusion time from minutes to hours:
Infusion time (hr) = 20 minutes / 60 minutes/hr
Infusion time (hr) = 1/3 hour
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 200 mL / (1/3) hr
Flow rate (mL/hr) = 200 mL x (3/1) hr
Flow rate (mL/hr) = 600 mL/hr

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 ["30"]
Explanation
Given:
Total insulin in solution: 100 units
Volume of solution: 250 mL
Infusion rate: 12 units/hour
Step 1: Determine the concentration of insulin in the solution:
Concentration (units/mL) = Total insulin (units) / Volume of solution (mL)
Concentration (units/mL) = 100 units / 250 mL
Concentration (units/mL) = 0.4 units/mL
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Infusion rate (units/hr) / Concentration (units/mL)
Infusion rate (mL/hr) = 12 units/hr / 0.4 units/mL
Infusion rate (mL/hr) = 30 mL/hr
