A nurse is preparing to administer cefazolin IVPB over 20 min. Available is cefazolin 1 g in 100 mL of dextrose 5% in water (DSW). The drop factor of the manual IV tubing is 15gtt/mL. The nurse should set the IV infusion to deliver how many gtt/min? (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 ["75"]
Step-by-Step Calculation
Understanding the Problem
We need to administer 100 mL of cefazolin over 20 minutes.
The drop factor of the tubing is 15 gtt/mL.
We need to calculate the drip rate in gtt/min.
Calculations
Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Total volume (mL) / Infusion time (min)
Infusion rate = 100 mL / 20 min = 5 mL/min
Calculate the drip rate:
Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)
Drip rate = 5 mL/min X 15 gtt/mL = 75 gtt/min
The nurse should set the IV infusion to deliver 75 gtt/min.

Correct Answer is ["125"]
Explanation
Step-by-Step Calculation
Understanding the Problem
We need to administer 1000 mL of 0.9% sodium chloride over 8 hours.
We need to calculate the infusion rate in mL/hr.
Calculations
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 1000 mL / 8 hr = 125 mL/hr
The nurse should set the IV pump to deliver 125 mL/hr.
Correct Answer is ["56"]
Explanation
Convert hours to minutes: 3 hours X 60 minutes/hour = 180 minutes
Calculate the total number of drops: 500 mL X 20 gtt/mL = 10,000 gtt
Calculate the drip rate: 10,000 gtt / 180 minutes = 55.56 gtt/min
Round to the nearest whole number: 56gtt/min
