A nurse is preparing to administer dextrose 5% in water (DSW) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual 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 ["8"]
Convert hours to minutes: 3 hours X 60 minutes/hour = 180 minutes
Calculate the total number of drops: 150 mL X 10 gtt/mL = 1500 gtt
Calculate the drip rate: 1500 gtt / 180 minutes = 8.33 gtt/min
Round to the nearest whole number: 8 gtt/min

Correct Answer is ["117"]
Explanation
Infusion time in hours = 3 hours
Infusion rate (mL/hr) = 350 mL / 3 hours = 116.67 mL/hr
Rounded to the nearest whole number = 117 mL/hr
Correct Answer is ["325"]
Explanation
The client is prescribed 5,200 mL of fluid over the first 24 hours. To find out how many mL/hr the IV pump should be set to infuse for the first 8 hours, we can divide the total volume by the total time.
Let’s calculate:
Rate=TotalVolume/TotalTime
Substituting the given values:
Rate = 5200mL /24hr ≈ 216.67mL/hr
However, this is the rate for the entire 24 hours. The question asks for the rate for the first 8 hours. It’s common in burn injury treatment to administer half of the total 24-hour fluid volume in the first 8 hours. So, we need to calculate half of the total volume and then find the rate for the first 8 hours:
HalfofTotalVolume = 5200mL/2 = 2600mL
Rateforfirst8hours = HalfofTotalVolume / 8hr
Substituting the given values:
Rateforfirst8hours = 2600mL/8hr = 325mL/hr
So, the nurse should set the IV pump to deliver 325 mL/hr for the first 8 hours.
