Question 1 of 5
A nurse is preparing to administer 0.9% sodium chloride (NS) 3000 mL IV to infuse over 24 hr. The drop factor on the 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: B
Rationale:
To calculate the rate of IV infusion in gtt/min, we first need to determine the total volume to be infused per minute. 3000 mL over 24 hr is 125 mL/hr (3000 mL / 24 hr).
Then, convert 125 mL/hr to mL/min by dividing by 60, resulting in approximately 2.08 mL/min (125 mL/hr / 60). Next, convert mL/min to drops/min using the drop factor of 10 gtt/mL, giving us 20.8 gtt/min. Since we need to round to the nearest whole number, the correct rate of infusion is 21 gtt/min (rounded up from 20.8).
Therefore, choice B (21) is the correct answer.
Choices A, C, and D are incorrect as they do not result from the calculation.
