Question 1 of 5
A nurse is preparing to administer dextrose 5% in water 350 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: The correct answer is A: 19 gtt/min.
To calculate the drip rate, use the formula: mL/hr = gtt/min × drop factor. First, convert 3 hours to minutes (3 hr × 60 min/hr = 180 min).
Then, calculate the mL/min infusion rate (350 mL ÷ 180 min = 1.944 mL/min). Now, use the drop factor of 10 gtt/mL to find the gtt/min (1.944 mL/min × 10 gtt/mL = 19.44 gtt/min). Since you can only administer whole drops, round down to the nearest whole number, giving you 19 gtt/min. Other choices are incorrect as they do not result from the correct calculations.
