A nurse is to infuse two 1L bags of normal saline to a patient at 80ml/hr. How many hours will it take to infuse the total amount of normal saline?
(Round to the whole number. Assume no interruptions in the infusion.)

Answer and Explanation

The Correct Answer is ["25"]

To calculate the number of hours required to infuse two 1L bags of normal saline at a rate of 80 ml/hr, you can use the following formula:

Time (hours) = Total volume (ml) / Infusion rate (ml/hr)

First, calculate the total volume of normal saline to be infused:

Total volume = 2 bags x 1L/bag x 1000 ml/L = 2000 ml

Now, plug this into the formula:

Time (hours) = 2000 ml / 80 ml/hr

Time (hours) = 25 hours

So, it will take 25 hours to infuse the total amount of normal saline at a rate of 80 ml/hr, assuming no interruptions in the infusion. Rounded to the nearest whole number, it will take 25 hours.
