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? (Round the answer to the nearest whole number.)

Correct Answer: A

Rationale:
To calculate the IV flow rate in drops per minute (gtt/min), we use the formula: (Volume to be infused in mL ÷ Time in minutes) × Drop factor. Given: Volume = 350 mL, Time = 180 minutes (3 hours), Drop factor = 10 gtt/mL. Using the formula: (350 ÷ 180) × 10 = 19 gtt/min. This is rounded to the nearest whole number, giving us 19 gtt/min.
Choice A is correct because it correctly calculates the IV flow rate based on the given parameters.

Choices B, C, and D are incorrect as they do not accurately calculate the flow rate.
