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.
To find the infusion time, we can use the formula:
Infusion Time = Volume of IV Solution / Infusion Rate
Given:
Volume of IV Solution = 460 mL
Infusion Rate = 90 mL/h
Substituting these values into the formula, we have:
Infusion Time = 460 mL / 90 mL/h
To calculate this, we divide the volume of IV solution by the infusion rate:
Infusion Time = 5.11 hours
Rounded to two significant figures, the infusion time is approximately 5.1 hours.
