2) 10 hrs
3) 15 hrs
4) 20 hrs

Answer 1

The infusion time for a 500 ml chemotherapy IV with a drip factor of 15 gtts/ml set at a flow rate of 25 gtts/min is 5 hours. The calculation involves converting the volume into drops and then dividing by the flow rate.

Step-by-step explanation:

To determine the infusion time for a 500 ml chemotherapy IV with a drip factor (infusion set delivering) of 15 gtts/ml set at 25 gtts/min, you would perform a calculation to find out how many minutes it would take for the entire volume to be infused. The total volume to be infused is 500 ml. Using the drip factor, which refers to the number of drops per milliliter (gtts/ml), we can convert the volume into drops.

The calculation is as follows:

First, calculate the total number of drops by multiplying the volume by the drip factor: 500 ml × 15 gtts/ml = 7500 gtts.

Then divide the total number of drops by the flow rate (drops per minute): 7500 gtts ÷ 25 gtts/min = 300 minutes.

Convert minutes into hours by dividing by 60: 300 minutes ÷ 60 = 5 hours.

Therefore, the infusion time required is 5 hours.
