A nurse practitioner prepares 460. mIL of an IV of normal saline solution to be delivered at a rate of 90. mL/h. What is the infusion time, in hours, to deliver 460. mI?

Express your answer to two significant figures and include the appropriate units

To find the infusion time in hours, we can divide the volume of the IV solution by the flow rate:

infusion time = volume / flow rate

Using the given values:

infusion time = 460 mL / 90 mL/h

Calculating this division, we find:

infusion time ≈ 5.11 hours

Rounded to two significant figures, the infusion time is approximately 5.1 hours.
