What is the drip rate in mL/hour if an infusion of 300 mL is administered over 6 hours?

To determine the drip rate in mL/hour, you need to divide the total volume of the infusion by the total time in hours over which the infusion is administered. In this case, you have a total infusion volume of 300 mL that is to be given over 6 hours.

To calculate the drip rate:

1. Take the total volume: 300 mL.

2. Divide it by the total time: 6 hours.

The calculation looks like this:

[ \text{Drip rate (mL/hour)} = \frac{300 \text{ mL}}{6 \text{ hours}} = 50 \text{ mL/hour} ]

This means that the drip rate at which the infusion should be administered is 50 mL/hour. This is why the correct answer is the one indicating 50 mL/hour, as it reflects the accurate calculation based on the given volume and time for the infusion.
