How many gtt/min should the nurse set the IV infusion to deliver if administering moxifloxacin 400 mg in 250 mL over 60 minutes with a drop factor of 15 gtt/mL?

To determine the correct drip rate in gtt/min (drops per minute) for the IV infusion of moxifloxacin, you start with the volume of fluid to be infused, the infusion time, and the drop factor provided.

You have a total volume of 250 mL to be infused over 60 minutes. First, you need to convert this volume to a drip rate in drops per minute. The drop factor of the IV set is given as 15 gtt/mL, meaning that for each milliliter of fluid that is infused, 15 drops will be delivered.

The first step is to calculate the total number of drops that will be infused over the entire time period:

1. Multiply the volume to be infused (250 mL) by the drop factor (15 gtt/mL): ( 250 , \text{mL} \times 15 , \text{gtt/mL} = 3750 , \text{gtt} )

2. Next, divide the total number of drops by the time of the infusion (60 minutes) to find the drip rate: ( \frac{3750 , \text{gtt}}{60 , \text
