Question 1 of 5
A provider prescribes dextrose 5% in water (D5W) IV to infuse at 100 mL/hr. The drop factor on the IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number.)
Correct Answer: C
Rationale: The correct answer is C: 100.
To calculate the IV flow rate in gtt/min, first convert the prescribed volume rate from mL/hr to mL/min by dividing by 60 (100 mL/hr รท 60 = 1.67 mL/min).
Then, multiply the mL/min by the drop factor (1.67 mL/min x 60 gtt/mL = 100 gtt/min). This ensures the correct administration rate of D5W.
Choice A is incorrect as it does not match the calculated value.
Choices B and D are also incorrect as they do not reflect the accurate conversion and multiplication process.
