Correct Answer is ["25"]
Explanation
To calculate the flow rate in drops per minute (gtt/min) for the IV infusion of clindamycin, you can use the following formula:
Flow rate (gtt/min) = (Volume to be infused (mL) * Drop factor) / Time (minutes)
First, you need to determine the volume to be infused. In this case, it's 100 mL. The drop factor is given as 15 gtt/mL, and the time is 60 minutes (1 hour).
Now, plug these values into the formula:
Flow rate (gtt/min) = (100 mL * 15 gtt/mL) / 60 minutes
Flow rate (gtt/min) = (1500 gtt) / 60 minutes
Flow rate (gtt/min) = 25 gtt/min
So, the nurse should set the flow rate to deliver 25 gtt/min for the IV infusion of clindamycin.
