Question 1 of 5
A nurse is preparing to administer 1.000 mL of lactated Ringer's IV over 6 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:
To calculate the IV flow rate in gtt/min, we first convert 6 hours to minutes (6 hrs x 60 min/hr = 360 min).
Then, we divide the total volume to be infused (1000 mL) by the total time in minutes (360 min), which gives us 2.78 mL/min. Next, we multiply 2.78 mL/min by the drop factor (10 gtt/mL), resulting in 27.8 gtt/min. Since we can't administer partial drops, we round up to the nearest whole number, which is 28 gtt/min.
Therefore, the correct answer is A (28 gtt/min). Other choices are incorrect because they do not align with the accurate calculation based on the given information.
