For an IV fluid bolus of 200 mL of dextrose 5% in water to be given over 30 minutes with a drop factor of 15 gtt/min, what should be the rate set for the manual IV infusion?

To determine the correct rate for the manual IV infusion, it is essential to calculate the infusion rate in drops per minute based on the volume of fluid to be administered, the time over which it should be delivered, and the drop factor of the IV set.

In this case, you need to infuse 200 mL of dextrose 5% in water over a period of 30 minutes. To find the infusion rate in mL per minute, you divide the total volume by the total time.

Calculating this:

200 mL ÷ 30 minutes = 6.67 mL/min

Next, you need to convert the mL per minute rate into drops per minute (gtt/min) using the drop factor of the IV set, which is given as 15 gtt/mL. This means that for every mL, 15 drops will be delivered.

Now, you can calculate the drop rate:

6.67 mL/min × 15 gtt/mL = 100.05 gtt/min

When you round this to the nearest whole number, the infusion rate is set to approximately 100 gtt/min.

Thus, the rationale for choosing the answer that corresponds to 100 gtt/min
