A nurse is preparing to administer 000 mL of lactated Ringer's IV over 6 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 ["28"]
Calculate the total infusion time in minutes:
6 hours X 60 minutes/hour = 360 minutes
Calculate the total number of drops:
1000 mL X 10 gtt/mL = 10,000 gtt
Calculate the drip rate:
Drip rate (gtt/min) = Total drops / Total infusion time (minutes)
Drip rate = 10,000 gtt / 360 minutes = 27.78 gtt/min
Rounded to the nearest whole number, the drip rate is 28 gtt/min.

Correct Answer is ["50"]
Explanation
Total volume to infuse = 50 mL
Total infusion time in minutes = 20 minutes
Drop factor = 20 gtt/mL
Drip rate (gtt/min) = (Total volume in mL) X (Drop factor) / (Total infusion time in minutes)
= 50 mL X 20 gtt/mL / 20 minutes = 50 gtt/min
Correct Answer is ["0.4"]
Explanation
Step-by-Step Calculation
Understanding the Problem
We need to administer 2000 units of heparin.
The available concentration of heparin is 5000 units/mL.
We need to find the volume to administer.
Calculations
Set up a proportion:
5000 units / 1 mL = 2000 units / x mL
Cross-multiply:
5000x = 2000
Solve for x:
x = 2000 / 5000
x = 0.4 mL
The nurse should administer 0.4 mL of heparin.
