Question 1 of 5

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? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: A

Rationale: The correct answer is A: 8 gtt/min.
To calculate the drip rate in gtt/min, we first need to determine the total drops to be infused over 3 hours. 150 mL over 3 hours is 50 mL/hr. Next, convert mL/hr to gtt/hr: 50 mL/hr x 10 gtt/mL (drop factor) = 500 gtt/hr.
To find gtt/min, divide 500 gtt/hr by 60 min = 8.33 gtt/min, rounding to the nearest whole number gives 8 gtt/min.
Therefore, the nurse should set the manual IV infusion to deliver 8 gtt/min.
Other choices are incorrect because they do not follow the correct calculation based on the drop factor and infusion rate.
