A nurse is preparing to administer an IV fluid bolus of 500 mL 0.9% sodium chloride over 60 min. 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 if it applies. Do not use a trailing zero.)
The Correct Answer is ["83"]
Given:
Total volume to infuse: 500 mL
Infusion time: 60 minutes
Drop factor of tubing: 10 gtt/mL
To find:
Drip rate (gtt/min)
Step 1: Calculate the total number of drops
Total drops = Total volume x Drop factor
Total drops = 500 mL x 10 gtt/mL = 5000 gtt
Step 2: Calculate the drip rate
Drip rate = Total drops / Infusion time in minutes
Drip rate = 5000 gtt / 60 minutes = 83.33 gtt/min
Step 3: Round to the nearest whole number
83 gtt/min

Correct Answer is ["12"]
Explanation
Given:
Desired infusion rate: 1,200 units/hr
Available concentration: Heparin 25,000 units in 250 mL DSW
To find:
Infusion rate (mL/hr)
Step 1: Calculate the concentration of heparin in mL/hr
Concentration (units/mL) = Total units / Total volume
Concentration (units/mL) = 25,000 units / 250 mL = 100 units/mL
Step 2: Calculate the infusion rate in mL/hr
Infusion rate (mL/hr) = Desired infusion rate (units/hr) / Concentration (units/mL)
Infusion rate (mL/hr) = 1,200 units/hr / 100 units/mL = 12 mL/hr
Correct Answer is ["8"]
Explanation
Given:
Total volume to infuse: 150 mL
Infusion time: 3 hours
Drop factor of tubing: 10 gtt/mL
To find:
Drip rate (gtt/min)
Step 1: Convert infusion time to minutes
3 hours x 60 minutes/hour = 180 minutes
Step 2: Calculate the total number of drops
Total drops = Total volume x Drop factor
Total drops = 150 mL x 10 gtt/mL = 1500 gtt
Step 3: Calculate the drip rate
Drip rate = Total drops / Infusion time in minutes
Drip rate = 1500 gtt / 180 minutes = 8.33 gtt/min
Step 4: Round to the nearest whole number
8 gtt/min
