A nurse is preparing to administer dextrose 5% in water (DW) 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?
Correct answer
A
Rationale
To calculate the IV infusion rate in gtt/min, we first need to determine the total volume to be infused over 3 hours. 150 mL over 3 hours equals 50 mL/hr. Next, convert 50 mL/hr to gtt/hr using the drop factor of 10 gtt/mL, giving us 500 gtt/hr. To find gtt/min, divide 500 by 60 (minutes in an hour), which equals approximately 8. Therefore, the nurse should set the manual IV infusion to deliver 8 gtt/min. This ensures the correct administration rate of dextrose 5% in water. Other choices are incorrect as they do not result from the correct calculation based on the given information.
